Description

Background Technology

[0001] Electronic devices (such as computing systems) may typically include one or more media drives, such as solid-state drives (SSDs), hard disk drives (HDDs), CD-ROM drives, or DVD drives. One or more reception locations (e.g., drive bays) may be included in the chassis of the electronic device used to receive these media drives. Media drives (multiple drives) may be installed directly in these reception locations, or they may be first received in drive carriers, which themselves may be received in the reception locations. For example, drive carriers may be used in computing systems (such as servers, high-performance computing systems, data storage devices, converged or hyperconverged systems, or other computing systems) to facilitate the installation and removal (e.g., hot-swapping) of media drives on the computing system.

[0002] Drive carriers are used to configure media drives, such as solid-state drives (SSDs), as field-replaceable units (FRUs), allowing the drives to be hot-swapped into computing systems. Therefore, drive carriers are defined by the physical form factor of SSDs or drives, configured to house them, and standardized by industry form factors (e.g., SSD form factors). For example, the Enterprise and Data Center Standard Form Factor (EDSFF) is designed for data centers using servers that utilize storage devices such as SSDs. As a form factor, it defines specifications such as dimensions and electrical interfaces that storage devices should have to ensure that data center operators, server manufacturers, and SSD manufacturers can produce products compatible with those from multiple manufacturers. Therefore, the EDSFF drive mentioned here refers to a drive having a form factor specified in one of the EDSFF family of standards, including but not limited to SFF-TA-1006, SFF-TA-1007, or SFF-TA-1008, and the EDSFF drive carrier is a drive carrier configured to house and support EDSFF drives. Because drivers may have different physical dimensions, they may also have different edge arrangements, different mounting hole positions, and different LED indicator arrangements. Therefore, different driver carriers are used on different drivers with different physical dimensions. Attached Figure Description

[0016] It should be emphasized that, according to industry standard practice, the various features are not drawn to scale. In fact, for ease of discussion or explanation, the dimensions of the various features can be increased or decreased at will. Detailed Implementation

[0017] The following describes illustrative examples of the claimed subject matter. For clarity, this specification does not describe all features of an actual implementation. It is understood that in the development of any actual implementation, many implementation-specific decisions may be made to achieve developer-specific goals, such as adhering to system-related and business-related constraints, which will vary from implementation to implementation. Furthermore, it is understood that such development work, while complex and time-consuming, is routine for those skilled in the art who possess the knowledge of this disclosure.

[0018] As stated herein, the article “a” has its common meaning in the patented technology, namely “one or more”. In this document, the term “about” when applied to a numerical value generally refers to a quantity within the tolerance range of the device producing that value, or in some instances, to ±10%, ±5%, or ±1%, unless otherwise expressly stated. Furthermore, the term “substantially” in this document means a quantity ranging from approximately 51% to approximately 100%, or almost all, or all, or for example, approximately 51% to approximately 100%. Moreover, the examples in this document are for illustrative purposes only and are intended for discussion only, not limitation.

[0019] As stated in this document, “providing” an item means having possession and / or control of that item. For example, this may include forming (or assembling) part or all of an item from its constituent materials, and / or possessing and / or controlling an item that has been formed.

[0020] Indicator LEDs are typically used to indicate the status of a drive. A drive may include activity indicator LEDs and status indicator LEDs. An activity indicator LED may blink whenever the drive is accessed (typically a read / write operation). A status indicator LED can indicate different operational states of the drive. For example, a status indicator LED can indicate when the drive is not detected by the system, when the drive is online, when the drive is ready to be removed, or when the drive has failed. Different drives have different physical dimensions and may have different indicator LED arrangements. In particular, the indicator LED positions of solid-state drives conforming to the E1.S ESDFF specification may differ from those of solid-state drives conforming to the E3.S EDSFF specification. Due to these differences in indicator LED positions, different light guide designs are used for different drives conforming to different form factor specifications. To support these different light guide designs, different drive carrier designs exist for different drives. Designing, tooling, manufacturing, and installing drive carriers for different drives requires additional time and cost. Furthermore, warehousing and managing the inventory of drive carriers with different designs adds to the workload and cost of inventory management.

[0021] The subject matter disclosed herein provides an adaptable light guide housing for different light guide designs, such that the light guide housing (capable of holding light guides of different designs) can be mounted in a universal driver carrier for drivers with different form-size specifications. In some instances, the subject matter of the invention provides a universal driver carrier for EDSFF drivers having either E1.S or E3.S form-size specifications. Because the light guide housing mounted inside the driver carrier can accommodate light guides of various designs, any light guide can be mounted into the housing, depending on which EDSFF driver (E1.S or E3.S) will be mounted in the driver carrier. With the universal light guide housing mounted within the carrier, the universal driver carrier can be used for drivers with multiple form-size specifications, instead of using driver carriers specifically designed for each type of driver. By using a universal driver carrier with an adaptable light guide housing, the development and production of driver carriers can be simplified and cost-effective.

[0022] This article describes an example of a configurable optical guide housing. This housing is adaptable to accommodate optical guides with various designs for different EDSFF drives, which have different dimensional parameters, for example, those found in the EDSFF form-size specification. In some examples, the optical guide may include a base structure and a top cover, which are configured together to mount either a first or a second optical guide on a drive carrier, wherein the first and second optical guides may have different arrangements. In one example, the housing is designed to accommodate both EDSFF drives conforming to the E1.S specification and solid-state drives conforming to the E3.S specification, with one optical guide mounted at a time. Because the housing inserts into a universal drive carrier, the universal drive carrier can accommodate two EDSFF drives conforming to different form-size specifications (E1.S or E3.S). Therefore, by using a universal drive carrier with a configurable optical guide housing, the development and production of drive carriers and optical guides can be simplified and cost-effective.

[0023] Figure 1A This is an exploded view showing a light guide housing 100 according to one embodiment of the subject matter. The light guide housing 100 can hold a light guide 102, which is designed to mate with an EDSFF driver having an E3.S form factor specification. The driver may have a first indicator light-emitting diode (LED) on the front side for indicating driver power and activity. The driver may have a second indicator LED on the front side for indicating driver operation or fault conditions. In one example, the light guide housing 100 may be mounted in a driver carrier of the driver.

[0024] The light guide housing 100 has a two-piece structure, including a base structure 104 and a top cover 106. The base structure 104 and the top cover 106 can be snapped together. The base structure 104 and the top cover 106 are together configured to mount the light guide 102. The light guide 102 is also referred to as the first light guide 102. In some examples, such as Figure 1B As shown, the base structure 104 and the top cover 106 are together configured to mount a second light guide 108. The second light guide 108 is designed to mate with an EDSFF driver having an E1.S. shape-size specification. The light guide housing 100 is configured to mount one light guide at a time. The first light guide 102 and the second light guide 108 have different light guide arrangements, which are configured to receive light from different LED arrangements associated with different driver size parameters. That is, in some examples, the first light guide 102 is designed to be a driver for an LED having an E3.S. shape-size specification and having two horizontally arranged LEDs (e.g., at two predetermined positions spaced apart along the horizontal direction), while the second light guide 108 is designed to be a driver for an LED having an E1.S. shape-size specification and having two vertically arranged LEDs (e.g., at two predetermined positions spaced apart along the vertical direction).

[0025] like Figure 1A As shown, the light guide 102 has a pair of elongated light-conducting portions 102a and 102b. Light-conducting portion 102a extends between the light receiving end 110 and the light emitting end 112, and light-conducting portion 102b extends between the light receiving end 114 and the light emitting end 116. When the light guide housing 100 and the light guide 102 are mounted in the driver carrier, the light receiving ends 110 and 114 are arranged near the rear side of the front guide rail (as described below as front guide rail 406), thus adjacent to (e.g., directly in front of) the position of the LED of the driver mounted on the driver carrier, wherein the driver has a first LED arrangement, such as an arrangement comprising horizontally arranged LEDs. (Refer to...) Figure 1B The second light guide 108 has a generally Y-shaped structure, including an elongated first light guide 108-a and a second light guide 108-b. The first light guide 108-a extends between the light receiving end 118 and the light emitting end 120, and the second light guide 108-b extends between the light receiving end 122 and the light emitting end 124. When the light guide housing 100 and the second light guide 108 are mounted in the driver carrier, the light receiving ends 118 and 120 are arranged near a front rail (such as front rail 406), thereby being adjacent to (e.g., directly in front of) the LED of a second type of driver mounted on the driver carrier, wherein the second type of driver has a second different LED arrangement, such as an arrangement including vertically arranged LEDs.

[0026] exist Figure 1A and 1BIn this configuration, the first light guide 102a and the second light guide 102b, which can be supported within the housing 100, are configured to be compatible with the LED indicator positioning of an EDSFF driver having an E3.S form factor specification. Similarly, the first light guide 108-a and the second light guide 108-b, which can also be supported within the housing 100, are configured to be compatible with the LED indicator positioning of an EDSFF driver having an E1.S form factor specification. Specifically, the light receiving end 110 of the first light guide 102a and the light receiving end 114 of the second light guide 102b are oriented close to the indicator LED of the E3.S EDSFF driver, so that when connected to the driver carrier, both light receiving ends 110 and 114 are horizontally aligned with a spacing and position consistent with the LED of the E3.S EDSFF driver. On the other hand, when the light receiving end 118 of the first light guide 108-a and the light receiving end 122 of the second light guide 108-b are oriented close to the indicator LED of the E1.SEDSFF driver, the light receiving ends 118 and 120 are horizontally aligned with the E1.S EDSFF driver LED at the same spacing and position when connected to the driver carrier. Therefore, regardless of whether an E1.SEDSFF driver or an E3.S EDSFF driver is installed in the driver carrier, the adaptable housing 100 according to the example here can retain either the first light guide 102 with two elongated light conductors 102a and 102b or the second light guide 108 with two elongated light conductors 108-a and 108-b. The first light guide 102 and the second light guide 108 can be adapted to redirect the light indicated by the EDSFF driver LED to their respective light emitting ends, namely light emitting ends 112 and 116 for the first light guide 102 and light emitting ends 120 and 122 for the second light guide 108. Furthermore, regardless of whether an E1.S EDSFF driver or an E3.SEDSFF driver is installed, the spacing and orientation between the light emitters 112 and 116 and between the light emitters 120 and 124 on the front surface 126 of the base structure 104 are the same.

[0027] Refer again Figure 1AThe base structure 104 has a rear surface 128 opposite to the front surface 126. The front surface 126 refers to the surface of the base structure 104 facing the user of the light guide housing when the light guide housing 100 is mounted in the driver carrier. The base structure 104 also includes a first light guide cavity 130 and a second light guide cavity 132 spaced apart from the first light guide cavity 130. The first light guide cavity 130 has a first end 130a located at the front surface 126 and a second end 130b located at the rear surface 128. The second light guide cavity 132 has a first end 132a located at the front surface 126 and a second end 132b located at the rear surface 128. Each of the first light guide cavity 130 and the second light guide cavity 132 is a channel formed on the base structure 104 and configured to hold a light guide therein.

[0028] The base structure 104 further includes a raised ramp 134 extending between the first optical guide cavity 130 and the second optical guide cavity 132. The raised ramp 134 has a first edge 134a adjacent to the first optical guide cavity 130 and a second edge 134b adjacent to the second optical guide cavity 132. Furthermore, as... Figure 1A As shown, the top cover 106 has a cutout 136. When the top cover 106 and the base structure 104 mate, the cutout 136 is located above the second edge 134b of the raised ramp 134, and the second edge 134b of the raised ramp 134 is parallel to the edge of the cutout 136. The base structure 104 may also include a slot 138 extending through the front surface 126 and the rear surface 128 of the base structure 104. The slot 138 is configured to receive a ridge-like extension formed on an adapter reference surface, the adapter being formed in a recess in the driver carrier. In various embodiments, the base structure 104, the top cover 106, and their sub-components / parts are made of plastic. Examples of plastic materials may include polycarbonate and polycarbonate / acrylonitrile-butadiene-styrene (PC-ABS).

[0029] The base structure 104 may further include a pair of sidewalls 140 and 142 (also referred to as first sidewall 140 and second sidewall 142) extending between the front surface 126 and the rear surface 128. The first sidewall 140 and second sidewall 142 may extend perpendicularly between the front surface 126 and the rear surface 128. A first locking clip 144 is formed on the first sidewall 140, and a second locking clip 146 is formed on the second sidewall 142. The top cover 106 has a first recess 148 and a second recess 150, wherein when the top cover 106 is mounted on the base structure 104, the first recess 148 engages with the first locking clip 144, and the second recess 150 engages with the second locking clip 146. The first locking clip 144 and the second locking clip 146 may interlock with the first recess 148 and the second recess 150, thereby ensuring that the top cover 106 is snap-fitted onto the base structure 104. When the top cover 106 is mounted on the base structure 104, the locking clips 144 and 146 on the base structure 104 can be bent, allowing the top cover 106 to be properly seated on the base structure 104. Specifically, refer to... Figure 1A The first locking clip 144 can be bent in the direction shown by arrow T1, and the second locking clip 146 can be bent in the direction shown by arrow T2. Since the first locking clip 144 and the second locking clip 146 are made of plastic material, as long as the top cover 106 is installed in place on the base structure 104, the first locking clip 144 and the second locking clip 146 will lock and reset in the vertical position, thereby engaging with the first groove 148 and the second groove 150 of the top cover 106, so as to detachably fasten the top cover 106 to the base structure 104.

[0030] The base structure 104 also includes a locking socket 152. The locking socket 152 is formed on a first sidewall 140 of the base structure 104. Although not shown in the figures, another locking socket similar to the locking socket 152 may also be formed on a second sidewall 142. Therefore, locking sockets can be provided on each pair of sidewalls 140 and 142. Each locking socket is configured to receive a drive carrier (e.g., Figure 5A and 5B (As shown) The corresponding flange on the adapter of the main body.

[0031] Furthermore, the top cover 106 includes a first retaining wall 154 and a second retaining wall 156. When the light guide housing 100 is inserted into the driver carrier frame (e.g., Figure 5A and 5B In the recess of the actuator carrier frame (such as the first retaining wall 154 and the second retaining wall 156, the first retaining wall 154 and the second retaining wall 156 can be formed in the recess of the actuator carrier frame (such as the first retaining wall 154 and the second retaining wall 156). Figure 5A and 5BThe light guide housing 100 moves within the corresponding wall socket (as shown). The wall socket is formed on each side of the driver carrier frame to receive the first retaining wall 154 and the second retaining wall 156. As long as the retaining walls 154 and 156 are inside the socket, the light guide housing 100 is prevented from sliding out of the recess.

[0032] Figure 2A and 2B The front and rear perspective views of the light guide housing 100 in Figure 1 are shown with the first light guide 102 installed. (Refer to...) Figure 2A A top cover 106 is mounted on a base structure 104, with a first light guide 102 held between them. The light-emitting end 112 of the first light-conducting portion 102a of the first light guide 102 extends from the first end 130a of the first light guide cavity 130. The light-emitting end 116 of the second light-conducting portion 102b of the first light guide 102 extends from the first end 132a of the second light guide cavity 132. (Refer to...) Figure 2B The light receiving end 110 of the first light transmitting part 102a of the first light guide 102 extends from the second end 130b of the first light guide cavity 130. The light receiving end 114 of the second light transmitting part 102b of the first light guide 102 extends from the second end 130b of the second light guide cavity 132.

[0033] Figure 3A and 3B The front and rear perspective views of the light guide housing 100 in Figure 1 are shown, with the second light guide 108 installed. A top cover 106 is mounted on a base structure 104, with the second light guide 108 held between them. Figure 3A As shown, the light emitting end 120 of the first light-conducting portion 108a of the second light guide 108 extends from the first end 130a of the first light guide cavity 130. The light emitting end 124 of the second light-conducting portion 108b of the second light guide 108 extends from the first end 132a of the second light guide cavity 132. The light receiving end 118 of the first light-conducting portion 108-a of the second light guide 108 extends from the cut-off portion 136. At least a portion of the first light-conducting portion 108-a is disposed and held at the edge of the cut-off portion 136 and the raised ramp. Figure 3A and 3B Between the edges (not shown), the light receiving end 118 of the first light-conducting portion 108a of the second light guide 108 extends from the cut-off portion 136. The light receiving end 122 of the second light-conducting portion 108-b of the second light guide 108 extends from the second end 132b of the second light guide cavity 132. The thickness of the base structure 104 is W millimeters (mm). In some examples, the thickness "W" can range from 5.5 mm to 7.5 mm.

[0034] Figure 4This is a top isometric view of the drive carrier 400, which is also referred to as the "drive carrier frame 400" or "frame 400". Figure 4 As shown, the frame 400 comprises a hybrid two-piece structure, including a first frame portion 402 made of a metal material and a second frame portion 404 made of a plastic material. The first frame portion 402 and the second frame portion 404 are interconnected, thereby forming a structure configured to receive and mount a media drive for an electronic device (such as a computing device), including but not limited to a solid-state drive. In one embodiment described below, the frame 400 is configured to receive and mount an EDSFF drive. It should be understood that... Figure 4 Not intended to show a specific shape, size, or other structural detail accurately or to scale, embodiments of frame 400 may have different numbers or arrangements of components shown, and may also include other components not shown. Furthermore, it should be understood that the disclosed frame 400 may be used to mount different types and configurations of media drives, and may have different shapes, sizes, and features, and is not limited to a particular drive technology.

[0035] Frame 400 includes a front guide rail 406 having a first end 405, a second end 407, and a body 408 extending in a transverse direction T between the first end 405 and the second end 406. Frame 400 also includes a first side guide rail 410 and a second side guide rail 412. The first side guide rail 410 extends from the first end 405 of the front guide rail 406 in a longitudinal direction L perpendicular to the transverse direction T, and the second side guide rail 412 extends from the second end 407 of the front guide rail 406 in a longitudinal direction L perpendicular to the transverse direction T and is parallel to the first side guide rail 410. In this way, the front guide rail 406, together with the first side guide rail 410 and the second side guide rail 412, forms frame 400, which is configured to receive a generally cuboid-shaped driver (located within an open space within the first side guide rail 112 and the second side guide rail 114) and mount the driver for insertion into a generally cuboid-shaped driver holder. For example, the body 408 of the front guide rail 406 includes a front surface 414 and a rear surface 416. When the driver is mounted to the frame 400, the rear surface 416 is adjacent to and faces the driver. The first side guide rail 112 and the second side guide rail 114 are configured to slide into the driver bracket. When the frame 400 is mounted to the driver bracket, the user can access the front surface 414.

[0036] The front guide rail 406 includes a recess 418. The recess 418 is a through hole formed in the body 408 of the front guide rail 406. As shown in Figures 1 to 3B, the recess 418 is configured to receive and mount the light guide housing 100. Ridge extension 420 (as shown in Figures 1 to 3B) Figure 5A (As shown in the enlarged view) is formed on the body 408 of the front guide rail 406. The base structure 104 of the light guide housing 100 has a slot 138 for receiving the ridge extension 420 (as shown in Figures 1 to 1). Figure 3B (As shown). The light guide housing 100 (equipped with a first light guide 102 or a second light guide 108) can be inserted longitudinally into the recess 418. When the light guide housing 100 is inserted into the recess 418, the slot 138 can slide against the ridge extension 420. It should be noted that the light guide housing 100 can be inserted into the recess 418 as long as the slot 138 and the ridge extension 420 are aligned. Therefore, the ridge extension 420 allows the light guide housing 100 to be inserted into the recess 418.

[0037] Figure 5A yes Figure 4 A partial magnified view of the front of the driver carrier frame 400. Figure 5A A portion of the front guide rail 406 is shown. A first adapter 422 is formed on the body 408 of the front guide rail 406. The first adapter 422 forms the sidewall of a recess 418 extending in the opposite direction to the longitudinal direction L. The first adapter 422 includes a first flange 424. When the light guide housing 100 is inserted into the recess 418, the first flange 424 can slide into a locking socket (locking socket 152 as shown in Figures 1 to 3B).

[0038] Figure 5B yes Figure 4 A partially enlarged rear view of the driver carrier frame 400. A second adapter 426 is formed on the body 408 of the front guide rail 406. The second adapter 426 forms the sidewall of the recess 418, opposite to the first adapter 422, and extends in a direction opposite to the longitudinal direction L. The second adapter 426 includes a second flange 428. When the light guide housing 100 (as shown in Figures 1 to 3B) is inserted into the recess 418, the second flange 428 can slide into the locking socket 152 (as shown in Figures 1 to 3B). Therefore, each of the first flange 424 and the second flange 428 is received by a corresponding locking socket formed on the base structure 104 of the light guide housing 100 (as shown in Figures 1 to 3B). Since the first flange 424 and the second flange 428 are locked in their corresponding sockets, the light guide housing is prevented from shifting from its position in the recess 418. This ensures a tight fit between the light guide housing 100 and the driver carrier frame 400, allowing the user to easily hot-swap the driver carrier frame 400 (with the light guide housing 100 mounted) from the driver tray without the risk of the light guide housing shifting out of position. When the light guide housing 100 is inserted into the recess 418, the adapters 422 and 426 on the base structure 104 can be bent so that the top cover 106 is mounted on the base structure 104. Specifically, refer to... Figure 5AThe first adapter 422 can be bent in the direction shown by arrow X1, and the second adapter 424 can be bent in the direction shown by arrow X2. Since the first adapter 422 and the second adapter 426 are made of plastic, they can be elastically snapped back into place once the light guide housing 100 is installed in the recess 418. After the first adapter 422 and the second adapter 426 snap back into place, the first flange 424 and the second flange 428 are respectively received by corresponding locking sockets formed on the base structure 104 of the light guide housing 100, thereby locking the light guide housing 100 in the recess 418. Furthermore, the frame 400 also includes a first wall socket 430 and a second wall socket 432. The first wall socket 430 and the second wall socket 432 are formed on a portion of the body 408 of the frame 400, which forms the boundary of the recess 418. When the light guide housing 100 is inserted into the recess 418, the retaining wall portion ( Figure 1A As shown, 154 and 156 can slide into the first wall socket 430 and the second wall socket 432. Specifically, the first retaining wall 154 of the light guide housing 100 can slide into the first wall socket 430, and the second retaining wall 156 of the light guide housing 100 can slide into the second wall socket 432, thereby forming a tight fit between the retaining wall portion and the corresponding socket. This prevents the light guide housing 100 from sliding out of the recess 418.

The base structure also includes a raised ramp extending between the first light guide cavity and the second light guide cavity. The raised ramp includes a first edge adjacent to the first light guide cavity and a second edge adjacent to the second light guide cavity. The light guide housing also includes a top cover having a cut-off portion. In step 704, method 700 includes inserting the light guide housing into a recess in a front guide rail of the driver carrier, such as driver carrier frame 400. Inserting the light guide housing into the recess exposes the front surface of the base structure to the front portion of the driver carrier. In step 706, method 700 includes providing the light guide housing with a first light guide, such as... Figure 1A The light guide 102, or the second light guide, such as Figure 1B Any one of the light guides 108. The light guide housing is configured to carry one light guide at a time, wherein the first light guide and the second light guide have different light guide arrangements.

[0042] In some examples, method 700 may include inserting a driver-containing carrier into a driver tray of an electronic device, such that the front portion of the driver carrier is exposed to the front portion of the electronic device. Furthermore, in some examples, when the light guide housing is inserted into the recess, a ridge-like extension is formed on the driver carrier body, such as ridge-like extension 420 (e.g., Figures 4 to 6B ), and slots that penetrate the front and back of the base structure, such as slot 138 ( Figures 1A to 3B and Figure 6A , 6B Interaction between the two. Furthermore, when the light guide housing is inserted into the recess, a layer is formed in the adapter (such as...). Figure 5A and 5B Each flange on adapters 422 and 426 shown (as shown) Figure 5A and 5B The flanges 424 and 428 shown herein correspond to the locking sockets (such as those on the sidewall of the base structure of the light guide housing) located on the light guide housing. Figure 1A and 1B The locking sockets 152 shown are locked together.
