Abstract

System chassis (100; 200; 800; 1100), comprising: a frame (110; 210; 1110) having a width, depth and height; and a plurality of partitions (120a-120d; 220; 820; 1020; 1120) coupled to the frame and forming a plurality of receptacles (121; 221), each configured to accommodate an electronics compartment (160; 260; 1160) containing an electronic assembly (170; 270; 1170), wherein each of the plurality of partitions comprises a metal sheet having a front edge (126; 226; 1026), a rear edge (228; 1028) and two side edges (122, 124; 222, 224; 1022, 1024), the two side edges being attached to two side walls (112, 114; 212, 214;812, 814) of the frame, and wherein the front edge of the metal sheet has a concave shape, such that the distance between the front edge and the rear edge of the metal sheet decreases continuously when moving laterally from one of the side edges to the center of the front edge, and increases continuously when moving laterally from the center to the other of the side edges.

Description

INTRODUCTION

[0001] Some electronic systems comprise a variety of electronic devices (e.g., servers, network devices, power supplies, etc.) housed in a common mechanical enclosure called the system chassis. Each of these electronic devices includes an electronic assembly (e.g., a system board with a processor and memory, etc.) and a mechanical support structure or enclosure that supports and / or houses the electronic assembly, which may be referred to herein as an electronic assembly carrier. The electronic assemblies can be inserted into corresponding slots or receptacles in the system chassis.

[0002] One or more dividers are often integrated into the system chassis. The dividers help define the slots or receptacles that house the electronic assemblies, with the dividers being positioned as separators between each electronic assemblies as the assemblies are installed into the system chassis. The dividers can help support the electronic assemblies and provide signal isolation between the electronic assemblies. The dividers are typically attached to two opposite sides of the system chassis, and sometimes the dividers are attached to a rear side of the system chassis. However, the dividers are usually not attached to the front of the system chassis - the front of the system chassis is often left relatively open to allow unobstructed insertion of trays. The dividers can be made of sheet metal, e.g.Steel, and be relatively thin to limit their weight, space requirements and costs.

[0003] Some electronic systems are configured for rack installation. For example, a typical rack-based system chassis typically conforms to the Electronics Industry Association (EIA) EIA-310 standard. EIA-310 allows a variety of mounting configurations, including varying heights and depths for the electronics bays. However, all of these configurations fit into a system chassis with a maximum width of 19 inches, limiting the width of the electronics bays to 17.5 inches. Other system chassis may conform to different standards and / or have different dimensions. BRIEF DESCRIPTION OF THE DRAWINGS

[0005] In some system chassis, the dividers, especially those made of thin metal, may flex slightly. This flexion is most common at the leading edges of the dividers, which are not directly supported by the system chassis. In some cases, this flexion can be caused by gravity pulling on the dividers. In other cases, this flexion can be caused by external objects pressing on the system chassis, such as the weight of another system stacked on top of the system chassis. If the flexion or flexion becomes excessive, a user may be unable to insert an electronics mounting tray into the system chassis due to interference between the tray and the flexing divider.When attempting to insert an electronic assembly into a receptacle with a curved divider, in some cases the curved divider may interfere with and damage the physical connectors on the back of the electronic assembly that are used to connect the electronic assembly to other electronic assemblies in the system chassis.

[0006] In general, the wider the dividers, the more likely they are to sag and the more severe the sag will be. While sag can sometimes occur in common rack-based system chassis around 19 inches wide, sag is often a much more significant problem in wider system chassis. Some newer system chassis designs, for example, can be as wide as 30.5 inches or more. The thinner the dividers, the more likely sag and the more severe the sag will be. Some newer system chassis designs may have relatively thin dividers to allow electronics bays to be placed closer together (thus increasing the number of such bays that can fit in a given size enclosure), as well as to reduce weight and cost.As a result, the wide and thin partition walls in these systems can bend or flex even more along their leading edges (the edge not attached to the system chassis). Furthermore, in some cases, it is not possible to provide the partition walls with support structures (such as ribs, hems, or other support structures) to prevent flexion, as in some cases it is desirable to keep the walls thin and lightweight, and such support structures can result in increased thickness and / or weight.

[0007] To solve the problems associated with curved partitions, the examples described herein may utilize a system chassis including one or more partitions having a concave shape along the leading edge of the partitions. In other words, instead of the leading edge of the partition extending in a straight line perpendicular to the two lateral sides of the partition, such that the partition has a substantially rectangular profile, the leading edge in the examples described herein has a concave shape in which a center of the leading edge is offset rearward relative to the two lateral sides of the leading edge.More specifically, the concave shape is such that the distance between the leading edge and the trailing edge of the bulkhead continuously decreases as one moves laterally from one side edge to a center of the leading edge and continuously increases as one moves laterally from the center to the opposite side edge. In some examples, the concave shape may be symmetrical about the center of the leading edge. For example, the concave shape may be a "V" shape, a curved shape (e.g., a semicircle, a semi-ellipse, a parabola, part of a hyperbola, etc.), or another concave shape. In some examples, the concave shape allows the leading edge to serve as a lead for engagement with the electronic subrack to prevent deflection of the bulkhead when the electronic subrack is inserted into the system chassis between the bulkheads.When the tray is inserted into the system chassis, the tray initially engages the divider at the two lateral sides of the front edge, as these are the forward-most portions of the divider (due to the concave shape of the front edge). The divider sags very slightly near the lateral sides (because the lateral sides are attached to the system chassis), so the divider does not interfere with or prevent the tray from being inserted during initial engagement. Therefore, the lateral sections of the tray can slide under the divider during initial engagement. While there may be significant bulge near the center of the front edge, the center of the front edge is behind the tray during initial engagement (due to the concave shape of the front edge), so the drooping center section does not interfere with the tray at this time.As the tray is pushed further into the system chassis after the initial snap, the parts of the tray already under the divider touch the divider and lift the parts of the divider not yet in contact with the tray but at a front contact point between the tray and divider. This lifting of the divider at the front contact points avoids interference that could otherwise occur, allowing the tray to be inserted further. As the tray is pushed in, the front contact points between the divider and a front edge of the electronics tray advance along the front edge from the side edges of the divider to the center of the front edge, with the tray gradually lifting more and more of the divider.As the contact points advance, the area of ​​contact / overlap between the divider and the electronics tray increases, gradually reducing the deflection or flexion of the divider. When the tray reaches the midpoint of the leading edge of the divider, the deflection or flexion can be substantially or completely eliminated, reducing or eliminating the interference between the electronics compartment and the divider.

[0008] In some examples, one or more of the partitions may include two support structures extending along each of the two side edges of the partition. The two support structures may be used to secure the partition to the system chassis. For example, the support structure may be flanges that are integrally mounted perpendicular to a flat portion of the partition.

[0009] In some examples, the system chassis may be configured to operate as a computing system with a plurality of electronics compartments containing electronic assemblies. The electronic assemblies may include, for example, compute nodes, storage nodes, switches or other network devices, communication interface nodes, etc.

[0010] The figures describe various devices, systems, and methods consistent with aspects of the present disclosure.

[0011] Fig. is a block diagram illustrating a system 10 having a system chassis 100. It should be understood that Fig. is not intended to depict specific shapes, dimensions, or other structural details accurately or to scale, and that implementations of the system 10 and the system chassis 100 may have different numbers and arrangements of the illustrated components and may also include other parts not shown.

[0012] As in Fig. As shown, the system 10 includes a system chassis 100, and the system chassis 100 includes a frame 110 and a set of partitions 120a-120d. The frame 110 and the set of partitions 120 are connected to each other to form a set of receptacles 121. In particular, each pair of adjacent partitions 120, together with portions of the frame 110, may define and partially enclose an open volume corresponding to one of the containers 121. The receptacle 121 may be configured to receive an electronics compartment 160. In some examples, the system 10 includes one or more such electronics trays 160. In Fig. For example, an electronics compartment 160 is shown within the receptacle 121 formed by the partitions 120a and 120b and the frame 110. As shown, one electronics compartment 160 is present, however, the frame 110 is configured to accommodate any number of electronics compartments similar to the electronics compartment 160. The electronics compartment 160 also includes an electronic assembly 170, which is described further below. In some examples, the system 10 consists of the frame 110 without any of the electronics compartments 160 installed therein.

[0013] For the sake of simplicity, the system 10 is described here in relation to the Fig. , in which the partition walls 120 are generally horizontal, and the directional terms used herein for various components of the system 10, such as "side," "top," "bottom," etc., are used herein with reference to this illustrated orientation. However, it should be understood that the system 10 may have other orientations and configurations, as described in more detail below; in such case, the directional terms used herein with reference to the illustrated orientation may be different in the other orientation. For example, a "top" of the frame 110 may be in the orientation of Fig. become a lateral side of the frame 110 when the chassis 100 is rotated 90 degrees.

[0014] The frame 110 may have the general shape of a hollow cube or a hollow rectangular cuboid (with one or more sides omitted or interrupted and / or openings formed therein) having a height, width, and depth that can accommodate one or more electronics compartments 160. The width and height dimensions are shown in Fig. where the depth dimension is perpendicular to the width and height dimensions (ie extending into the side in Fig. extends). The frame 110 may be constructed from any suitable construction material. Suitable construction materials include, but are not limited to, metals such as steel, copper, brass, aluminum, or other relatively rigid materials such as plastics. In one example, the frame 110 is formed from steel and has a height of 48 inches, a width of 30.5 inches, and a depth of 24 inches. In some embodiments, all or a portion of the frame 110 may include a subframe consisting of structural rails and cross members that form a skeleton with the desired dimensions for use with the frame 110. One or more panels or other structures may be attached to the subframe to form an outer shell having at least a top wall 116, a bottom wall 118, and two side walls 112 and 114. These panels or walls may be formed, for example, from sheet metal.In some examples, the shell of the frame 110 may also include a back wall (not shown). In some examples, the back wall is discontinuous (i.e., it is composed of multiple pieces that are not necessarily directly connected to each other) and / or has one or more openings to allow for the routing of cables or other infrastructure and / or to allow airflow. The front of the frame 110 may, in some examples, be missing a wall or panel to allow for insertion and removal of the electronics trays 160. In other examples, the frame 110 may have a front wall or panel or door (not shown) that is removable or can be opened (e.g., on a hinge) to allow insertion or removal of the electronics compartments 160, but in such examples, the dividers 120 are not attached to the front wall / door.

[0015] References will occasionally be made below to the top, bottom, front, rear, and side surfaces of the frame 110 or the system chassis 100. These terms generally refer to the locations or areas associated with the sides or faces of the frame 110. For example, references to the top, bottom, and side surfaces of the frame 110 generally refer to the areas at or around the top wall 116, the bottom wall 118, and the side walls 112 and 114, respectively. References to the front and rear surfaces of the frame 110 may generally refer to the other two sides of the frame 110 that are perpendicular and tangent to the top, bottom, and side walls 116, 118, 112, and 114. Note that the front and rear surfaces do not necessarily have corresponding walls.As used herein, the “front” differs from the back in that the front is the side from which the electronics trays 160 are inserted into the system chassis 100.

[0016] In some examples, the frame 110 may also include additional structures (not shown), such as vertical or horizontal partition walls connected to other parts of the frame, e.g., to one of the walls 112, 114, 116, and 118. These vertical or horizontal partition walls may, for example, form additional compartments or containers for accommodating other components of the system 10.

[0017] Each of the partitions 120 is made from a sheet of metal whose width corresponds to the width of the frame 110. The sheet of metal may be substantially flat. In some examples, the sheet of metal may have features such as ribs or notches in its surface. The depth of the partitions 120 may vary but is typically similar to the depth of the frame 110. The metal used to fabricate the partitions 120 may include, but is not limited to, steel, copper, brass, and aluminum. In one example, the partitions 120 are made from sheet steel. In some examples, the partitions are 0.71 mm (0.028 in) thick. In some examples, the partitions are 1.01 mm (0.040 in) thick. In some examples, the partitions are between 0.71 mm (0.028 in) and 1.01 mm (0.040 in) thick. In some examples, the partitions are less than 0.71 mm (0.028 in) thick. In some examples, the partition walls are thicker than 1.01 mm (0.040 in).In some examples, the partitions are substantially flat and have no additional features to minimize weight and reduce the space occupied by the partitions 120 within the frame 110.

[0018] Each of the partitions may be connected to the frame 110 using a suitable fastening mechanism. In some examples, the fastening mechanism may include attaching each of the partitions 120 to a portion of the sidewalls of the frame 110 with mechanical fasteners, such as rivets, bolts, or other fasteners. In other examples, each of the partitions 120 may be attached to a portion of the sidewalls of the frame 110 by soldering, welding, gluing, interlocking connections, or another fastening mechanism. More specifically, in some examples, a side edge 122 of the partition 120 is connected to the sidewall 112 and an opposite side edge 124 of the partition 120 is connected to the sidewall 114. In other examples, one or both side edges 122 or 124 of the partitions 120 are connected to intermediate structures (not shown), e.g.,with vertical partition walls (not shown) extending vertically between the top and bottom of the frame 110. Although the partition walls 120 in . Fig. are shown extending horizontally and connected to the side walls 112 or 114, this is only one possible configuration, and the partition walls 120 could be configured differently. For example, the partition walls 120 could extend vertically and be connected to the top and bottom walls 116 and 118. The partition walls 120 that extend horizontally, as in Fig. can be referred to as a horizontal configuration of the system chassis 100, while the partition walls 120 that extend vertically can be referred to as a vertical configuration. The principles of the present disclosure can apply equally regardless of the orientation of the system chassis 100. In embodiments in which the system chassis 100 has a different orientation than that illustrated, the directional terms used herein should be translated accordingly, e.g., what is referred to in Fig. shown horizontal configuration is described as being arranged on a "lateral side" of the chassis 100, in a vertical configuration it may be arranged on an "upper" or "lower" side of the chassis 100.

[0019] The electronics compartment 160 is shaped to fit into the receptacles formed by the dividers 120 and the frame 110. In some examples, the electronics compartment 160 has the general shape of a cube or a rectangular cuboid with a height, width, and depth. The electronics compartment 160 may be constructed of similar construction materials as the frame 110. In one example, the electronics tray is formed of steel and has a height of 1.75 inches, a width of 30.5 inches, and a depth of 24 inches. In some embodiments, all or a portion of the electronics compartment 160 may include a subframe structure similar to the structure described above for the frame 110.

[0020] The electronics compartment 160 contains an electronic assembly 170. The electronic assembly 170 includes a plurality of electronic components that are electrically connected to one another and that form all or part of an electronic device capable of performing a function or operation. Examples of electronic devices include, but are not limited to, a compute node, a storage node, a switch or other network device, a power supply unit, and a communications interface node. In some implementations, the electronics compartment may include one or more electrical connectors that interface between the electronic assembly 160 and other electronic components, such as other electronic assemblies 160 in electronics compartments 170 as part of the system chassis 100 or external to the system chassis 100.In some examples, power and / or communication connectors (not shown) may be disposed within the system chassis 100 at locations corresponding to the receptacles 121 so that they blindly connect to complementary connectors disposed on or within a rear surface of the electronics compartment 160 when the electronics compartment is inserted into the corresponding receptacle 121. These connectors may be disposed on a midplane or backplane (not shown) extending perpendicular to the dividers 120 and the side walls 112 and 114, thereby interconnecting the various electronic assemblies 170 installed in the system 10.In some examples, power and / or communication cables may be used in addition to or instead of a midplane or backplane circuit board to connect the various electronic assemblies 170 to each other and / or to other devices.

[0021] In Fig. The partition walls 120b-120d are shown as bent or curved downward (the curvature is exaggerated in the illustration for clarity, but the illustration is not intended to show the actual dimensions or extent of the curvature). The downward bending or deflection, also referred to as sagging, can be caused, for example, by the force of gravity on the horizontally oriented partition walls 120b-120d (in the horizontal configuration of the system chassis 100). In addition, the deflection can also be due to forces acting on the frame 110 and compressing it. Although the deflection in Fig. While shown facing downward, in some cases one or more of the horizontally oriented dividers 120 may bend or flex upward, for example, due to a force acting on the sides of the frame 110. In other implementations utilizing the vertical configuration of the system chassis 100, the vertically oriented dividers 120 may bend laterally, for example, due to forces acting on the top and / or bottom of the frame 110 (e.g., due to another object being stacked on top of the frame 110).

[0022] In Fig. The partition 120a is shown as flat and straight, while the other partitions 120b-120d are shown curved. The partition 120a is flat because the electronics compartment 160, together with the frame 110, was inserted into the receptacle formed by the partitions 120a and 120b. In other words, the partition 120a originally had a similar inclination to the partitions 120b-120d before the electronics compartment 160 was inserted. Each of the partitions 120a-120d has a front edge 126 (in Fig. only one is labeled), which, viewed from a perspective above or below the partition 120, has a concave shape, similar to the perspectives in Fig. shown. This concave shape is such that the distance between the leading edge and the trailing edge (not shown) of the partition 120 continuously decreases as one moves laterally from either side of the leading edge 126 (the sides of the leading edge 126 adjacent to the side edges 122 and 124 of the partition 120) toward the central portion of the leading edge 126. In other words, as one moves laterally along the leading edge 126 from the side edge 122 to the side edge 124, the front-to-back distance continuously decreases from the side edge 122 until reaching an inflection point at the central portion, and after the inflection point, the front-to-back distance now continuously increases as one moves from the central portion to the side edge 124.Thus, the lateral sides of the leading edge 126 (adjacent the side edges 122 and 124) are located further forward than all other portions of the leading edge 126, and the leading edge 126 may have an inflection point or minimum at the central portion of the leading edge 126, with this inflection point being the rearmost portion of the leading edge 126. The concave shape of the leading edge 126 may, for example, comprise a concave shape formed from two or more interconnected line segments, such as a V-shape. Fig. For example, FIG. 12A shows an example configuration of the partition walls 120 (in the form of the partition wall 220) with a V-shaped leading edge. As another example, the concave shape of the leading edge 126 may have a curved or arched shape, such as a semicircle, a semi-ellipse, a parabola, a hyperbola (or a portion thereof), an ogive, or another curve. Fig. For example, FIG. 12A shows an example configuration of the partition walls 120 (in the form of partition wall 1020) with a curved leading edge. As another example, the concave shape may consist of a combination of curved and linear segments. The concave shape of the leading edge 126 prevents the partition wall 120a, which initially has a sag, from interfering with the electronics compartment 160 at the beginning of insertion. As the insertion process progresses, the slope of the partition wall 120a is gradually reduced, so that the partition wall 120a remains relatively flat, as shown.

[0023] As mentioned above, the receptacles 121 are generally defined (i.e., bounded) by a pair of adjacent partition walls 120 along with portions of the frame 110. However, in some examples, one or more of the receptacles 121 may be defined by a single one of the partition walls 120 along with other portions of the frame 110. For example, in some examples, a topmost receptacle 121 is bounded by one of the topmost partition walls 120 and the top wall 116. As another example, in some cases, a bottom receptacle 121 is bounded by a lower one of the partition walls 120 and the bottom wall 118 of the frame 110.

[0024] In the Fig. A system chassis 200 is described that corresponds to various aspects of the disclosure. The system chassis 200 may be a configuration of the system chassis 100 described above. Thus, various components of the system chassis 200 may be similar to the components of the system chassis 100 described above. The above descriptions of the components of the system chassis 100 also apply to the similar components of the system chassis 200, so duplicate descriptions are omitted below for clarity. Similar components of the system chassis 100 and 200 are given reference numbers with the same last two digits, such as 110 and 210. Although the system chassis 200 may be a configuration of the system chassis 100, the system chassis 100 is not limited to the configuration of the system chassis 200.

[0025] Various elements of the System Chassis 200 or components thereof are illustrated in several figures. In describing the elements below, reference is made to one or a few figures that are considered particularly relevant to the element being described. Therefore, in the following description, the Fig. not necessarily described separately and in strict order, but rather switching back and forth between different illustrations. Furthermore, it should be understood that when reference is made to specific illustrations in relation to a particular element, other illustrations besides those identified may depict the same part from different perspectives.

[0026] The Fig. show a perspective view and a front view of the system chassis 200, respectively. The system chassis 200 includes a frame 210. The frame 210 has a top wall 216, side walls 212 and 214, and a bottom wall 218. The top wall 210, the side walls 212 and 214, and the bottom wall 216 are formed from one or more steel sheets. The frame 210 has rectangular openings at the front and rear of the frame 210. The frame includes a plurality of partition walls 220 having a front edge 226 and lateral side edges 222 and 224 (only one of the partition walls 220 is shown in the Fig. labeled). The partition walls 220 also have a rear edge 228 which Fig. is not visible, but in Fig. (and others). The Fig. The front edge 226 shown has a concave shape and tapers inwardly from the lateral side edges 222 and 224 to the center of the front edge 226. The side edges 222 and 224 are attached to the inner surface of the side walls 212 and 214, respectively, of the frame 210.

[0027] Each of the partition walls 220 is in Fig. with a bend or arc at the leading edge 226. As shown in Fig. As shown, the bend or bulge can be seen particularly with respect to a dashed line 271 running from one corner edge 222 to the other corner edge 224 across the width of the frame 210, as seen from the side, wherein the dashed line 271 indicates a nominal position of the partition wall 220 if no bulge were present. Note that the Fig. The curvature shown is exaggerated to make it more visually obvious and the actual dimensions are not shown.

[0028] Fig. is a plan view of one of the partition walls 220, with the rest of the system 200 not visible. The concave shape of the leading edge 226 is V-shaped towards the trailing edge 228. The distance from the leading edge 226 to the trailing edge 228 (along a line parallel to the side edges 212 and 214) is maximum at the sides 227a and 227b of the leading edge 226 (at the junction of the leading edge 226 with the side edges 212 and 224). This maximum value of the front-to-rear distance is in Fig. as distance 274. The distance between the leading edge 226 and the trailing edge 228 continuously decreases as one moves along the leading edge 226 from the side edge 227a to a center point 229. At the center point 229, the front-to-back distance reaches a minimum value, shown as distance 273. In particular, the front-to-back distance decreases linearly as one moves from the lateral side 227a to the center point 229. Similarly, the distance from the leading edge 226 to the trailing edge 28 continuously decreases as one moves along the leading edge 226 from the lateral side 227b to the center point 229, from the maximum value at the lateral side 227b to the minimum value at the center point 229. Thus, the leading edge 226 is symmetrical about the center point 229.

[0029] The difference between the distance 274 and 273, which may be referred to as the depth of the concave shape, may depend on several factors, such as the width of the dividers 220 and the material or thickness of the dividers 220, as well as the orientation of the system chassis 220. Each of these factors can affect the amount of bending or curvature (e.g., flexion) present in the dividers. Greater bending or flexion may require a greater depth of the concave shape to prevent excessive binding during contact between the electronics compartment and the divider. In some examples, the depth of the concave shape is three inches. In other examples, the depth may have a different value, including values ​​greater or less than three inches.

[0030] Fig. show four different states when installing an electronics compartment 260 into the system chassis from three different views. In particular, the Fig. show a first state, Fig. show a second state, Fig. show a third state, and the Fig. show a fourth state. The electronics compartment 260 is installed in the frame 210 by inserting the electronics compartment 260 into a receptacle 221. The receptacles 221 are formed by one of the partition walls 220, the two side walls 212 and 214, and either another adjacent partition wall 220 or another part of the frame, such as the top wall 216 or the bottom wall 218. In Fig. the receptacle 221 into which the tray 260 is inserted is the lowermost receptacle 221 defined between one of the partition walls 220 and the bottom wall 218 of the frame 210. Fig. are cross sections along 4-4 ​​in Fig. showing the top of the partition 220 in the frame 210 together with the electronics compartment 260. Fig. show perspective views of the electronics compartment 260 and the receptacle 221 in the frame 210. Fig. show rear views of the electronics compartment 260 and the container 221 in the frame 210.

[0031] Fig. show the electronics compartment 260 at a point where it is aligned with the receptacle 221 in the frame 210. In some embodiments, guide structures (not shown), such as rails or grooves, may be provided on one or both side walls 212 and 214 of the frame 210 between the dividers 220. Additionally, complementary guide structures may be attached to the electronics tray 260 that engage the guide structures of the frame 210. The electronics compartment 260 includes a frame 261, and in some examples, the complementary guide structures may be disposed on or in the sides 262 and 264 of the frame 261. As shown in the Fig. As shown, the frame 261 may include guide tabs 263 and 265 adjacent to or formed as part of the sides 262 and 264. The guide tabs 263 and 264 extend rearwardly beyond the front edge 266 of the frame 261, are located along the rear of the electronics compartment 260, and are aligned with the bottom surface of the partition 220 along each side edge 222 and 224.

[0032] Fig. show the areas 275 and 276, where the areas 275 correspond to the areas without contact or overlap between the partition 220 and the frame 261 and the areas 276 correspond to the areas with contact or overlap between the partition 220 and the frame 216. In the Fig. In the state shown, the tray 260 is not yet inserted into the receptacle 221, so that there is no contact / overlap between the partition 220 and the frame 261, as indicated by the non-contact area 275 extending across the width of the partition 220. As shown in Fig. As shown, the partition 220 in this state exhibits a significant curvature, with the partition 220 hanging below the upper surface of the tray 260. Thus, if the partition 220 had a conventional configuration without the concave leading edge, the partition 220 would interfere with the tray 260 and block its insertion. However, because the partition 220 has the concave leading edge 226, this curvature does not prevent the insertion of the tray 260, as described further below.

[0033] After the first state, which is in the Fig. As shown, the tray 260 may initially be inserted into the receptacle 221. In examples where the electronics compartment 260 includes tabs 263 and 265, the tabs 263 and 265 may be the first portions of the compartment 260 inserted into the receptacle 221. The divider 220 has little to no sag on the lateral sides (because the divider 220 is attached to the frame 220 at the lateral sides), and therefore the tabs 263 and 265 may fit beneath the divider 220 without interference. In some examples, the tabs 263 and 265 may include beveled or rounded insertion features on their top surfaces to ensure that the tabs 263 and 265 slide beneath the divider 220 without interference. As the tabs 263 and 265 slide under the partition 220, they may come into contact with the underside of the partition 220, which may serve to slightly lift the portions of the partition 220 immediately adjacent to the tabs 263 and 265.This ensures that when the front edge 266 of the tray 260 finally reaches the front edge 263, the front edge 266 can pass under the front edge 263 (at least in the area immediately adjacent to the tabs 263 and 265).

[0034] In other examples, tabs 263 and 265 are omitted. In this case, the lateral sides of leading edge 266 may be the first portion of leading edge 266 to engage leading edge 263. In such cases, the lateral sides of leading edge 266 may slide under bulkhead 220 for the same reasons as tabs 263 and 265 (i.e., they are located near the lateral edges where there is little to no slack).

[0035] Fig. show the electronics compartment 260 shortly after an initial insertion into the receptacle in the frame 210. The Fig. The state shown represents the point of first or initial contact between the front edge 266 of the electronics compartment 260 and the front edge 226 of the partition 220. The contact points between the front edge 266 of the tray 260 and the front edge 226 of the partition 220 are shown in the Fig. characterized by contact zones 290 and 291. 4B, 5B, and 6B. Those portions of the leading edge 266 that are closer to the center point 229 than the contact zones 290 and 291 have not yet made contact with the leading edge 226, while the portions of the leading edge 266 that are farther from the center point 229 than the contact zones 290 and 291 have already passed under the leading edge 226. In this state, portions of the frame 261 have passed under the partition 220, as indicated by the contact or overlap areas 276. These contact or overlap areas 276 correspond to the areas located between the side edges 222 and 224 of the partition 220 and the contact zones 290 and 291. At this initial point of insertion, the contact zones 290 and 291 are particularly close to the side edges 222 and 224, so that the contact or overlap areas 276 are small.The remaining portion of the leading edge 266 not within the contact areas 276 still lies within the no-contact or no-overlap area 275. In some embodiments, the guide structures described above, such as the guide tabs 263 and 264, may assist in snapping the electronics compartment into the frame 210. As shown in FIG. Fig. As shown, a certain amount of deflection remains in the partition wall 220, which is, however, less than that in Fig. existing amount of deflection. The contact between the tray 260 and the partition 220 at the contact zones 290 and 291 reduces the deflection because the tray 260 now supports a portion of the leading edge 226 of the partition 220, and thus the unsupported portion of the leading edge 226 is shorter than before.

[0036] As the tray 260 is further inserted into the receptacle 221, the leading edge 266 slides against the leading edge 226, and the contact points between the leading edge 266 and the leading edge 226 gradually shift inward toward the center point 229, as can be seen from comparing FIGS. 4A, 4C, and 4D. The contact points move inward toward the center point 229 due to the concave shape of the leading edge 226 as the tray 260 is inserted. Since the leading edge 266 is in contact with the underside of the partition 220 at the contact points, the tray 260 lifts the partition 220 more and more as the contact points move inward until the sag is effectively eliminated. At various points during this insertion process, portions of the partition 220 located near the center point 229 may experience some deflection / tilt, as shown in the Fig. shown, but this bulge in the center 229 does not prevent further insertion, because due to the convex shape of the front edge 226, the curved sections near the center 229 are behind the tray 260, as shown in the Fig. shown, and thus these curved portions do not interfere with the tray 260. When the leading edge 266 finally reaches the center 229 of the leading edge 226, the partition 220 will have been sufficiently raised by the progressive contact between the leading edge 266 and the leading edge 226.

[0037] For example, the Fig. shows the electronics compartment 260 at a further point of insertion into the receptacle in the frame 210. At this point of insertion, the contact points between the leading edge 266 and the leading edge 226 have shifted even further inward, as indicated by the contact zones 292 and 293. Thus, the contact or overlap areas 276 from each side 222 and 224 along the leading edge 226 are extended further to the contact zones 292 and 293. The remaining part of the leading edge 266 remains in the non-contact area 275. As shown in Fig. shown, the deflection of the partition wall 220 is compared to that in Fig. The deflection shown is very small, especially at the transition from the Fig. shown condition to that in Fig. In the state shown, the contact points move further inward, so that the length of the cantilevered portion of the leading edge 226 is reduced, resulting in a reduction in deflection.

[0038] Fig. show the electronics compartment 260 at an even more distant insertion point into the receptacle in the frame 210. At this point of insertion, the contact points between the leading edge 266 and the leading edge 226 are moved even further inward, as indicated by the contact zones 294 and 295. Thus, the contact or overlap areas 276 are even closer to the center 229 of the leading edge 226 and extend from the sides 222 and 224 to the contact zones 294 and 294. The small part of the leading edge 266 around the center 229 remains in the area of ​​no contact 275 with the leading edge 266. As in Fig. As shown, the sag of the partition 220 is almost completely eliminated. In particular, because the contact points are now quite close together, only a small length of the leading edge 226 remains unsupported, and therefore there is little to no deflection.

[0039] After the Fig. As shown, the tray 260 can be inserted further into the receptacle 221 until finally the contact points between the front edge 266 and the front edge 226 converge in the center 229 (not shown). At this point, the slack in the partition 220 is effectively eliminated (or at least reduced enough so that it is no longer a problem). Thereafter, further insertion of the tray 260 causes the front edge 266 to pass under the front edge 226 and move rearward until the Fig. The fully installed state shown is reached.

[0040] In some embodiments, the tray 260 may include structural features that ensure that only the front edge 266 and the tabs 263 and 265 (if present) come into contact with the front edge 226 of the divider 220 when the electronics tray is inserted into the receptacle up to the midpoint 229 in the frame 210. For example, the front edge 266 may have a height equal to or slightly greater than the height of the remaining portion of the electronics compartment 260. Furthermore, the front edge 266 may have a height greater than the height of any external structures, such as electronic connectors, located forward of the front edge 266 at the rear of the electronics compartment 260.

[0041] Fig. shows a perspective view of the electronics compartment 260 fully inserted and attached to the frame 210. The partition 220 rests on all or part of the top of the electronics compartment 260, eliminating the sag, similar to the partition 120a described above. As shown in Fig. As shown, the front 268 of the electronics compartment 260 is illustrated flush with the front of the frame 210. In other embodiments, the front may be recessed or protruding. Furthermore, some embodiments may include an additional mechanism for attaching the electronics compartment 260 to the frame 210 to hold the electronics compartment 260 in a fixed position. The attachment mechanism may be permanent, semi-permanent, or removable. The attachment mechanism may be present on the front, back, and / or sides of the electronics compartment 260. The attachment mechanism may include a latch or other form of attachment using fasteners, such as screws, or some form of clamping that exerts a force against either the electronics compartment or the frame 210.

[0042] Now to the Fig. A system chassis 800 is described in accordance with various aspects of the disclosure. The system chassis 800 may be a configuration of the system chassis 100 or 200 described above. Thus, various components of the system chassis 800 may be similar to the components of the system chassis 100 and 200 described above. The above descriptions of the components of the system chassis 100 and 200 are applicable to the similar components of the system chassis 800, so duplicate descriptions are omitted below for clarity. Similar components of the system chassis 100, 200, and 800 are given reference numbers with the same last two digits, such as: B. 110, 210 and 810. Although the System Chassis 800 can be a configuration of the System Chassis 100 or 200, the System Chassis 100 or 200 are not limited to the System Chassis 800 configuration.

[0043] Fig. show a perspective view and a front view of the system chassis 800, respectively. In this example, the partition walls 820 each include support structures 882 and 884 located on opposite sides. As shown in the Fig. As shown, these support structures 882 and 884 extend along and are coupled to the side walls 812 and 814, respectively, of the frame in the system chassis 880. In some examples, the support structures 882 and 884 extend from the front to the back of the frame. Each of the support structures 882 and 884 may extend along all or a portion of the side walls 812 and 814, respectively. Each of the support structures 882 and 884 is attached to the side walls 812 and 814 with mechanical fasteners. As shown, the support structure 882 is attached to the side wall 812 with a rivet 885. The support structure 884 is attached to the side wall 814 with a rivet 886 (in Fig. shown). In other embodiments, other mechanical fasteners such as screws, nuts, and bolts may also be used. Although only one mechanical fastener (e.g., rivet) is shown, multiple mechanical fasteners extending the length of the support structures 882 and 884 may be used. Furthermore, in some embodiments, the support structures 882 and 884 may be attached by other attachment mechanisms such as welding, gluing, engaging flanges or other engagement structures attached to the sidewalls 812 and 814, or any other attachment mechanism.

[0044] As shown, the support structures 882 and 884 are each formed as part of the partition 820. The support structures 882 and 884 are formed as flanges that are orthogonal to and below (or, in other examples, above) the horizontal portion of the partition 820. The partition 820 may, for example, be formed from a sheet of metal that is bent along two parallel lines on opposite sides to form the support structures 882 and 884. In this way, the support structures 882 and 884 are integrally connected to the partition 820. In other embodiments, the support structures 882 and 884 may be disposed above the partition 820. In some embodiments, the support structures 882 and 884 may be separate from the partition 820. In these embodiments, the support structures 882 and 884 can be attached to the partition wall 820 by fastening, welding, gluing, etc.be attached, or the partition 820 may rest on the support structures 882 and 884 without necessarily being attached thereto.

[0045] Fig. is a plan view of another example of a partition 1020. The partition 1020 is an example configuration of the partition 120 of the system chassis 100. Furthermore, in some examples, the partition 1020 in the system chassis 200 or 800 may be used instead of the partitions 220 or 820. In this example, the concave shape of the leading edge 1026 has a curved shape toward the trailing edge 1028. This is in contrast to the more angular concave shape formed from straight line segments in the partition 220 of Fig. is formed. The distance between the leading edge 1026 and the trailing edge 1028 along the side edge 1024 is shown as distance 1074. The distance between the leading edge 1026 and the trailing edge 1028 continuously decreases as one moves along the leading edge 1026 to a midpoint 1029, shown as distance 1073. Similarly, the distance between the leading edge 1026 and the trailing edge 1028 along the side edge 1022 continuously decreases as one moves along the leading edge 1026 to the midpoint 1029, by the same distances 1074 and 1073, respectively. As described above, the depth of the concave shape may depend on several factors that affect the amount of bend or curvature present in the partition 1020. In some examples, the depth is three inches, similar to the depth of the partition 220 described above.In other examples, the depth may have a different value, including values ​​greater or less than three inches.

[0046] As in Fig. As shown, the curved shape of the leading edge 1026 is in the form of a semicircle. Other curved shapes may also be used, such as a parabola, a semi-ellipse, or a hyperbola. More complex concave shapes may also be used, such as an acoustic horn or a pointed arch resembling a combination of a V-shape and a curved shape, or a curve created by reflecting one or more curved segments at the center 1029 (e.g., reflecting an exponential or logarithmic curve at the center 1029).

[0047] In the examples discussed so far, the convex shape of the leading edge is generally symmetrical at its center. However, in other examples, the convex shape is not necessarily symmetrical. For example, with respect to the partition wall 1020, the leading edge 1026 may include a curved segment between the side edge 1022 and the center point 1029 that is distinct from a curved segment between the side edge 1024 and the center point 1029, as long as both curved segments continuously decrease as they move inward from the side edges 1022 or 1024 toward the center point 1029.

[0048] Fig. is a block diagram that conceptually represents a computing system 1000. It is to be understood that Fig. It is not intended to depict specific shapes, dimensions, or other structural details accurately or to scale, and implementations of computing system 1000 may vary in the number and arrangement of the illustrated components and may also include other parts not shown. Computing system 1000 may be used as part of a multi-node, parallel computing system.

[0049] The computing system 1000 includes a system chassis 1100. The system chassis 1100 may, for example, be one of the system chassis 100, 200, or 800 described above. The system chassis 1100 includes a frame 1110. The frame 1110 includes a series of partitions 1120. The frame 1110 and the set of partitions 1120 are coupled together to form a set of receptacles in a manner similar to that described above. A set of electronics trays 1160 are attached to or mounted within the receptacles in the frame 1110. In the illustration shown, three electronics trays 1160 are attached to or mounted within three receptacles. In other implementations, the computing system 1100 can be configured to accommodate more or fewer electronics trays similar to the electronics tray 1160.

[0050] The frame 1110 and the partition walls 1120 may be made of a suitable construction material and configured in a manner similar to that described above. In particular, each of the partition walls 1120 has a front edge (not shown) having a concave shape. The concave shape of the front edge may be similar to that shown in Fig. described V-shape, which in Fig. described curved shape or other concave shapes, as long as the distance between the leading edge and the trailing edge of the partition 1120 continuously decreases as it moves laterally from one side edge to a center of the leading edge and continuously increases as it moves laterally from the center to an opposite side edge of the partition.

[0051] Each of the electronics compartments 1160 contains one or more electronic assemblies 1170. The electronic assemblies 1170 may be attached to the electronics compartments using any known attachment mechanism. Each of the electronic assemblies 1170 may be configured to perform the same operations and / or functions, or may be configured to perform different operations and / or functions as part of the operation of the computing system 1100. Examples of different types of electronic assemblies include, but are not limited to, a compute node, a storage node, a switch, and a communication interface node.

[0052] In some embodiments, each of the electronics compartments 1160 may also include structural features such as a frame, as well as separate top, bottom, and / or side walls as described above. In some embodiments, each of the electronics compartments 1160 may further include structural features associated with the front edge of the electronics compartment, as well as guidance structures, such as side tabs, that assist in the alignment, engagement, and insertion of the electronics compartment as part of the assembly or attachment of the electronics compartments 1160 to the frame 1110.

[0053] The system chassis 1100 also includes a power supply 1130 and a data bus 1140. In addition, each of the electronics compartments 1160 also includes a power supply interface 1176 and a data interface 1177. The power supply 1130 is connected to the power supply interface 1176 on each of the electronics bays 1160 and provides electrical power for operating the electronic assemblies 1170. The data bus 1140 establishes a data and signal communication connection between the electronic assemblies 1170 in each of the electronics compartments 1160 via the data interfaces 1177. In some embodiments, one or both of the power supply interfaces 1176 and the data interfaces 1177 are located on the rear of the system compartment.In some implementations, one or both of the connections between the power interfaces 1176 and the power supply 1130 and the data interfaces 1177 and the data bus 1140 may be made via either a backplane interconnect interface or a midplane interconnect interface on the system chassis 1100.

[0054] In some examples, compute system 1100 includes an HPC system, such as an HPE Cray EX system, an HPE Apollo system, or other HPC systems. In some examples, compute system 1100 includes a converged or hyperconverged compute system, such as an HPE ConvergedSystem, an HPE SimpliVity system, or other converged / hyperconverged system. In some examples, compute system 1100 consists of a collection of individual servers, such as HPE ProLiant servers or other servers.

[0055] Fig. describes an example method 1200 for mounting an electronics tray, e.g., the electronics tray 260, in a system chassis, e.g., the system chassis 200. In block 1210, an electronics tray 260 containing an electronic assembly 270 is aligned with an opening in a receptacle formed by two partition walls 220 and the sides of the frame 210 in the system chassis 200. One or more of the partition walls 220 have a front edge 226 having a concave shape as described above. The alignment is performed in a manner similar to the Fig. As described in the Fig. As shown, one or both of the side tabs 263 and 265 are aligned with the side walls 222 and 224 of the frame 210.

[0056] In block 1220, a front edge 266 of the electronics compartment 260 is engaged with the receptacle in the frame 210. The engagement of the electronics compartment 260 occurs in a similar manner as described above in the Fig. described. In particular, one or both corners of the leading edge 266 contact the leading edge 226 of the upper partition 220 used to form the receptacle at or near one or both corners of the leading edge 226 near the side edges 222 and 224.

[0057] In block 1230, the electronics compartment 260 is inserted into the receptacle in the frame 210. The insertion is carried out in a similar manner as above in the Fig. , as well as Fig.. In particular, a contact region advances incrementally along the concave-shaped leading edge 226 from an initial engagement point in block 1220 until the leading edge 266 of the electronics compartment 260 reaches a midpoint 229 on the leading edge 220. As the contact region advances to the midpoint 229, the bend or bulge initially present in the partition 220 is removed. The electronics compartment 260 can be inserted further into the receptacle without interference between the partition 220 and the electronics compartment 260.

[0058] In some embodiments, the electronics compartment 260 may contain more than one electronic assembly 270. Additionally, in some implementations, the electronics compartment 260 may contain one or more power interface connectors (e.g., power interface 1176) and one data interface connector (e.g., data interface 1177). Furthermore, these power interface connectors and data interface connectors may be connected to other electronics compartments 260 mounted on the system chassis 200 via a backplane interconnect interface or a midplane interconnect interface on the system chassis 200. In this manner, the system chassis 200 may be configured as a computing system, for example, computing system 1100.

[0059] The above description describes various types of electronic circuits. The term "electronic" as used herein should be understood broadly and includes all types of circuits that use electricity, including digital and analog circuits, direct current (DC) and alternating current (AC) circuits, circuits that convert electricity to another form of energy, and circuits that use electricity to perform other functions. In other words, no distinction is made here between "electronic" circuits and "electrical" circuits. In some cases, certain electronic circuits may also include processing circuits. Processor or processing circuits include circuits configured with logic to perform various operations.The logic of the processing circuitry may include specialized hardware for performing various operations, software (machine-readable and / or processor-executable instructions) for performing various operations, or any combination thereof. In examples where the logic includes software, the processing circuitry may include a processor for executing the software instructions and a storage device that stores the software. The processor may include one or more processing devices capable of executing machine-readable instructions, such as a processor, a processor core, a central processing unit (CPU), a controller, a microcontroller, a system-on-chip (SoC), a digital signal processor (DSP), a graphics processing unit (GPU), etc.In cases where the processing circuitry includes dedicated hardware in addition to or instead of the processor, the dedicated hardware may include any electronic device configured to perform specific operations, such as an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a complex-programmable logic device (CPLD), discrete logic circuits, a hardware accelerator, a hardware encoder, etc. The processing circuitry may also include any combination of dedicated hardware and processor plus software.

[0060] It should be understood that both the general description and the detailed description include examples that are explanatory and are intended to aid understanding of the present disclosure without limiting the scope of the present disclosure. Various mechanical, compositional, structural, electronic, and operational changes may be made without departing from the scope of this description and the claims. In some instances, well-known circuits, structures, and techniques have not been shown or described in detail in order not to obscure the examples. Like numerals in two or more figures represent like or similar elements.

[0061] In addition, spatial, positional, and relational terms are used herein to assist the reader in understanding examples of the implementations, but not to limit the implementation to any particular frame of reference, orientation, or positional relationship. For example, spatial, positional, and relational terms such as "above," "below," "side," "below," "below," "below," "above," "top," "proximal," "distal," and the like may be used herein to describe directions or to describe the spatial relationship of one element or feature to another element or feature, as depicted in the figures. These spatial terms are used in the figures with reference to frames of reference and are not limited to any particular real-world frame of reference. For example, the "up" direction in the figures does not necessarily correspond to "up" in a worldwide frame of reference (e.g.,away from the Earth's surface). If a different frame of reference than the one shown in the figures is considered, the spatial terms used here may need to be interpreted differently in that different frame of reference. For example, the direction described as "up" in one of the figures may correspond to a direction described as "down" in another frame of reference rotated 180 degrees with respect to the frame of reference of the figure. As another example, if a device is rotated 180 degrees in one world frame of reference compared to how it is represented in the figures, then an object described here as being "above" or "over" a second object with respect to the figures would be "below" or "beneath" the second object with respect to the world frame of reference.Furthermore, the positions of the objects shown in the figures were chosen for better illustration and description; however, in practical implementation, the objects may be positioned differently.

[0062] Furthermore, the singular forms "a," "an," and "the" also include the plural forms unless the context indicates otherwise. Furthermore, the terms "comprises," "including," "includes," and the like specify the presence of certain features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups. Components described as coupled may be directly coupled electronically or mechanically, or they may be indirectly coupled through one or more intermediate components, unless expressly stated otherwise.Mathematical and geometric terms are not necessarily to be used in accordance with their strict definitions unless the context of the description suggests otherwise, because a person having ordinary technical knowledge would understand that, for example, an essentially similar element functioning in an essentially similar manner could easily fall within the scope of a descriptive term even though the term also has a strict definition.

[0063] Making available: For the purposes of this article, "making available" means acquiring possession and / or control of the item. This may, for example, mean forming (or assembling) the item, in whole or in part, from its component parts and / or acquiring possession and / or control of an already formed item.

[0064] And / or: Occasionally, the term "and / or" is used here in conjunction with a list of items. This wording means that any combination of items in the list—from a single item to all items and every permutation in between—can be included. For example, "A, B, and / or C" means "one of {A}, {B}, {C}, {A, B}, {A, C}, {C, B}, and {A, C, B}."

[0065] Elements and their associated aspects that are described in detail in one example may, whenever practical, be included in other examples in which they are not specifically shown or described. For example, if an element is described in detail with reference to one example and not described with reference to a second example, the element may still be claimed as included in the second example.

[0066] Unless otherwise noted herein or apparent from the context, the use of terms of approximation such as "substantially," "approximately," "about," "approximately," "about," and the like is intended to disclaim mathematical precision and instead to refer to a range of variation including, but not strictly limited to, the stated value, property, or relationship.
