Description

[0002] In the field of servers, there are different size specifications for the width of the chassis, such as the relatively small 19-inch specification and the relatively large 21-inch specification. The 19-inch specification is the mainstream width for general-purpose servers, and the 21-inch specification is used in some OCP (open computer project) and ODCC (open data center committee) centralized power supply cabinets. In recent years, as the power consumption of central processing units increases, the size of the heat sink increases, and the number of memories increases, the structure of a server with a central processing unit equipped with a full-memory channel cannot be arranged in a small-size chassis.

[0003] In related technologies, a small-size chassis is directly changed to a large-size chassis to meet the layout requirements. However, in this way, the large-size chassis cannot be placed in a cabinet for a small-size chassis, which leads to the inability to use in a computer room that has been deployed with a small-size chassis. Instead, a new computer room must be built, and the application scenarios are very limited.

Detailed Implementation

[0070] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0071] The core of this invention is to provide a switching device that can accommodate a central processing unit with a full range of memory channels in a small-sized rack without replacing existing racks in the data center or building a new data center, which is beneficial for the diversification of customer server designs and the standardization of data centers.

[0072] The adapter provided by this invention includes a cabinet 1, an outer frame 2, and an extension 4. Please refer to [reference needed]. Figure 1 .

[0073] The width dimension of rack 1 is used to correspond to the width dimension of a smaller server. The specific direction of the width dimension of rack 1 is as follows: Figure 1 As shown in Figure W, rack 1 is used to house small-sized servers. Specifically, small-sized servers are in contrast to large-sized servers 3. For example, a small-sized server is a 19-inch server, and a large-sized server 3 is a 21-inch server. Rack 1 is used to house 19-inch servers. Through the setting of the outer frame 2 and the extension 4, this invention enables rack 1, which corresponds to 19-inch servers, to accommodate 21-inch servers. This allows the server structure with a central processing unit with fully configured memory channels to be laid out in a large-sized chassis to meet layout requirements. Furthermore, it allows large-sized chassis to be placed in rack 1, which corresponds to existing small-sized chassis. It can be used in data centers where small-sized chassis have already been deployed, making the application scenarios more flexible and unrestricted.

[0074] In a specific application, such as two full-channel central processors, due to the problem of excessive volume of the heat sink, only large-size servers 3 can meet the layout requirements of two central processors. Through the adapter device of the application, two full-channel central processors can be placed in a small-size server cabinet 1 corresponding to a small-size specification without reducing the memory number of the central processor to ensure the performance of the server, without replacing the existing server cabinet or building a new data center, which is beneficial to the diversification of customer server design and the normalization of data center.

[0075] Specifically, the outer frame 2 is arranged in the server cabinet 1, which is fixed in the server cabinet 1. The specific fixing method can be assisted by limiting parts, fastening parts, etc., which are not limited here.

[0076] Among them, please refer to Figure 1 , Figure 2 The height direction, width direction and length direction of the placement interval 201 are the same as the height direction, width direction and length direction of the server cabinet 1. The length direction here is as shown in L of Figure 1 , the width direction is as shown in W of Figure 1 , and the height direction is as shown in H of Figure 1 .

[0077] The outer frame 2 has a plurality of placement intervals 201 arranged along the width direction of the outer frame 2, and the placement intervals 201 are used to place large-size servers 3. The height dimension of the placement interval 201 is used to correspond to the width dimension of the large-size server 3, and the height in the height dimension of the placement interval 201 is as shown in the H direction of Figure 1 , and the width dimension of the large-size server 3 is as shown in the h direction of Figure 1 . The width dimension of the placement interval 201 is used to correspond to the height dimension of the large-size server 3, wherein the width in the width dimension of the placement interval 201 is as shown in the W direction of Figure 1 , and the height dimension of the large-size server 3 is as shown in the h direction of Figure 1 .

[0078] Taking a 19-inch server as an example, the 19-inch server is usually placed horizontally in the server cabinet 1, that is, the width direction, height direction and length direction of the 19-inch server correspond to the width direction, height direction and length direction of the server cabinet 1.

[0079] In the premise that the large-size server 3 is a 21-inch server, the 21-inch server is vertically placed in the outer frame 2 through the height space of the cabinet 1 corresponding to the 19-inch server, so that the large-size server 3 can be placed in the cabinet 1 corresponding to the small-size server. Here, the vertical placement means that the width dimension of the 21-inch server corresponds to the height dimension of the placement interval 201.

[0080] The extension piece 4 is arranged along the length direction of the outer frame 2, and the length direction of the extension piece 4 has a plurality of connecting portions, each of which can be connected with the outer frame 2 to change the length of the placement interval 201. Here, the length of the placement interval 201 is changed based on the ability to adapt to 21-inch servers of different lengths. The length range that can be formed by the extension piece 4 and the outer frame 2 is 780-920 mm. Specifically, the plurality of connecting portions can be a plurality of mounting holes on the extension piece 4, or can be a slide rail on the extension piece 4. As long as the extension piece 4 can move relative to the outer frame 2 to enable the outer frame 2 to connect connecting portions at different positions, the effect of increasing the length of the placement interval 201 can be achieved.

[0081] In a specific embodiment, the extension piece 4 can slide relative to the outer frame 2, either of the two is provided with a slide rail, and the other is provided with a sliding block. When the extension piece 4 slides to a certain position relative to the outer frame 2, the extension piece 4 needs to be locked to ensure the reliable stability of the placement interval 201. In this case, the distance that the extension piece 4 slides can be obtained by means of the scale on the inner side or the outer side of the extension piece 4, or the length of the placement interval 201 corresponding to the distance that the extension piece 4 slides can be directly obtained after the extension piece 4 slides a certain distance, so as to facilitate convenient and accurate adjustment. The locking mode of the extension piece 4 can be realized by means of hole position and screw cooperation to achieve reliable fixation.

[0082] In the embodiment, in the premise that the large-size server 3 is a 21-inch server, the height range of the outer frame 2 is 547-577 mm, and the width of the outer frame 2 is the width of a standard 19-inch cabinet, which is 448 mm. A plurality of placement intervals 201 are arranged in the outer frame 2, that is, at least two 21-inch servers can be placed in the outer frame 2. Of course, one 21-inch server can also be placed. For the 21-inch server, the height can be 1U, 2U or other. The height dimension of the 21-inch server is equal to the width dimension of the placement interval 201, and the corresponding placement interval 201 can be adapted according to the actual height of the 21-inch server. U can be a standard 45 mm, 46.5 mm, 48 mm or other, and can be customized according to actual needs without limitation.

[0083] In the embodiment, the large-size server 3 is vertically placed in the placement section 201, and the height of the placement section 201 satisfies the placement requirement of the large-size server 3 in the width direction, so that the large-size server can be placed in the cabinet 1 of the small-size server. When the central processing unit is arranged in the layout memory channel, even if the larger size cabinet is replaced to meet the layout requirement, the smaller size cabinet corresponding to the smaller size cabinet 1 of the smaller size cabinet can be directly used, without replacing the existing cabinet of the data center or building a new data center, which is beneficial to the diversification of customer server design and the normalization of data center. Specifically, the 21-inch server cabinet can be placed in the 19-inch server cabinet.

[0085] In a specific embodiment, the two side walls in the width direction of the cabinet 1 are provided with the strip-shaped supporting rail 101. When the outer frame 2 is disassembled relative to the cabinet 1, the outer frame 2 can be slid relative to the supporting rail 101 by pulling or pushing the outer frame 2, so as to realize the effect of convenient disassembly. The effect that the strip-shaped supporting rail 101 can realize is to support the bottom of the outer frame 2, so that when the outer frame 2 is relatively fixed on the supporting rail 101, the outer frame 2 and the large-size server 3 inside it have good stability.

[0086] In a specific embodiment, the two side walls in the width direction of the cabinet 1 are provided with the L-shaped supporting rail 101, the horizontal end of the supporting rail 101 is supported at the bottom of the outer frame 2, and the vertical end of the supporting rail 101 is supported at the side of the outer frame 2. The L-shaped supporting rail 101 forms reliable support for the bottom and the circumference of the outer frame 2, so that the outer frame 2 has good reliability and stability when it slides relative to the supporting rail 101. In this way, at least one of the horizontal end and the vertical end of the supporting rail 101 can be slidingly connected with the outer frame 2.

[0087] In the above two specific embodiments, it should be noted that after the outer frame 2 is slid relative to the supporting rail 101 to the position, the outer frame 2 and the supporting rail 101 still need to be fixed by means of fasteners, and the fasteners can be screws.

[0089] The two sides of the plug interface are provided with the folded edge 202, the folded edge 202 extends away from the direction of the placement interval 201, and the folded edges 202 on the two sides of the plug interface are used for connecting the two side walls in the width direction of the cabinet 1. Please refer to Figure 4 , the folded edge 202 is provided with a screw hole in the height direction, which is used for corresponding connection of the folded edge 202 and the square hole strip on the two sides of the cabinet 1, and the screw hole can be provided with multiple. The width direction and the height direction here are respectively indicated as W and H in Figure 1 and Figure 4 .

[0090] Among them, the folded edge 202 is folded outward relative to the overall structure of the outer frame 2, on the basis of the sliding connection of the outer frame 2 and the support rail 101, when the outer frame 2 is slid to the position, the folded edge 202 and the cabinet 1 are fixedly connected, the fixation of the outer frame 2 relative to the cabinet 1 is realized, the outer frame 2 and the large size server 3 arranged in the outer frame 2 have good stability and reliability.

[0091] In the embodiment, the outer frame 2 can be an integral piece, which is formed by processing a plate to ensure the structural strength and reliability.

[0092] On the basis of any of the above embodiments, please refer to Figure 4 , the outer frame 2 includes an outer frame body 206 and a cover plate 205, the outer frame body 206 and the cover plate 205 are integrally formed, the structural strength of the outer frame 2 is ensured by the integrally formed manner, in this case, the height of the corresponding placement interval 201 is not adjustable, and is directly designed according to the actual width of the corresponding large size server 3, so that different standards of large size servers 3 can be installed in the cabinet 1 corresponding to the small size server. The effect. The different standards here include but are not limited to scorpion standard, OCP standard and industry standard.

[0093] On the basis of any of the above embodiments, please refer to Figure 4The outer frame 2 comprises an outer frame body 206 and a cover plate 205 which is movable along the height direction of the outer frame body 206. The top of the outer frame body 206 has an opening, and the cover plate 205 is connected to the outer frame body 206 to close or open the opening. In this case, the height of the placement interval 201 formed by the outer frame 2 can be adjusted, specifically according to different specifications of the large-size server 3, so that the outer frame 2 has better applicability. In this case, considering the structural strength of the outer frame 2, reinforcing ribs can be provided on the cover plate 205 and / or the outer frame body 206 to increase the structural strength, so as to avoid the shaking of the outer frame 2 affecting the stable operation of the large-size server inside.

[0094] The cover plate 205 can be moved along the height direction of the outer frame body 206, and the specific arrangement manner is not limited. Specifically, the cover plate 205 can be moved up and down along the side wall of the outer frame body 206 to change the height of the placement interval 201, and a slide can be used. However, it should be noted that after the cover plate 205 is slid into place, it needs to be fixed to the outer frame body 206 by means of fasteners to ensure reliable connection of the cover plate 205 and the outer frame body 206, so as to ensure the reliable stability of the outer frame 2 as a whole.
