Description

Technical Field

[0001] The present invention relates to the technical field of servers, and more specifically, to a switching device. Background Art

[0002] In the server field, chassis width has different size specifications, such as the relatively small size of 19 inches and the relatively large size of 21 inches. Among them, 19 inches is the mainstream width of general servers, and 21 inches is used in some OCP (open compute project) and ODCC (open data center committee) centralized power supply cabinets. In recent years, with the increase in the power consumption of the central processing unit, the increase in the size of the radiator, and the increase in the number of memories, the server structure with a central processing unit with full memory channels can no longer be arranged in a small-sized chassis.

[0003] In the related art, a small-sized chassis is directly changed to a large-sized chassis to meet layout requirements. However, in this way, the large-sized chassis cannot be placed in the cabinet of the small-sized chassis, resulting in that it cannot be used in a computer room where a small-sized chassis has been deployed. It can only be used in a newly built computer room, and the application scenarios are very limited.

DETAILED DESCRIPTION

[0070] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0071] The core of the present invention is to provide a switching device that can arrange a central processing unit with full memory channels in a small-sized cabinet without replacing the existing cabinets in the computer room or building a new data center, which is conducive to the diversification of customer server design and the normalization of data centers.

[0072] The switching device provided by the present invention includes a cabinet 1, an outer frame 2, and an extension member 4. Figure 1 .

[0073] The width dimension of the cabinet 1 is used to correspond to the width dimension of the small-size server. Here, the direction of the width dimension of the cabinet 1 is as follows: Figure 1 As shown in W, the cabinet 1 is used to place small-sized servers. Specifically, the small-sized servers are relative to the large-sized servers 3. For example, the small-sized servers are specifically 19-inch servers, and the large-sized servers 3 are specifically 21-inch servers. The cabinet 1 is used to place the 19-inch servers. The present invention arranges the outer frame 2 and the extension 4 so that the cabinet 1 corresponding to the 19-inch server can place the 21-inch server, so as to meet the server structure with a central processing unit with full memory channels. It can be arranged in a large-sized chassis to achieve the layout requirements, and the large-sized chassis can be placed using the cabinet 1 corresponding to the original small-sized chassis, and can be used in the computer room where the small-sized chassis has been deployed. The application scenario is more flexible and not restricted.

[0074] In specific applications, for example, if the central processing units with two fully configured channels can only be placed in a large-sized server 3 due to the problem of excessive heat sink volume, the adapter device of the present application can be used to place the central processing units with two fully configured channels in a small-sized cabinet 1 corresponding to a smaller-sized chassis without reducing the memory number of the central processing unit to ensure server performance. This eliminates the need to replace existing cabinets in the computer room or build a new data center, which is conducive to the diversification of customer server design and the normalization of data centers.

[0075] Specifically, the outer frame 2 is disposed in the cabinet 1. The "being disposed in the cabinet 1" here specifically means being fixed in the cabinet 1. The specific fixing method can be by means of limiting components, fastening components, etc., which is not limited here.

[0076] Among them, please refer to Figure 1 , Figure 2 The height, width, and length directions of the placement interval 201 are respectively the same as those of the cabinet 1. The length direction here is as follows: Figure 1 The L in the figure indicates that the width direction is as follows Figure 1 The W in the figure indicates that the height direction is Figure 1 The H in the figure indicates.

[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 the large-size server 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 dimension of the placement interval 201 specifically refers to Figure 1 The H in the figure indicates the direction, and the width dimension of the large-size server 3 specifically refers to Figure 1 The h in the figure indicates the direction. 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 dimension of the placement interval 201 specifically refers to Figure 1 The W in the figure indicates the direction, and the height dimension of the large-size server 3 specifically refers to Figure 1 The h in the figure indicates direction.

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

[0079] On 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. The vertical placement here 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. The extension piece 4 has a plurality of connection parts in the length direction. Each connection part can be connected to the outer frame 2 to change the length of the placement interval 201. The specific change of the length of the placement interval 201 here is based on being able to adapt to 21-inch servers of different lengths. The specific length range that can be formed by the extension piece 4 and the outer frame 2 is 780~920mm. The specific plurality of connection parts can be a plurality of mounting holes on the extension piece 4 or a slide rail on the extension piece 4. As long as the extension piece 4 can be movable relative to the outer frame 2 so that the outer frame 2 can be connected to connection parts at different positions, the effect of increasing the length of the placement interval 201 can be achieved.

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

[0082] In this embodiment, under the premise that the large-size server 3 is a 21-inch server, the height range of the outer frame 2 is 547~577mm, and the width of the outer frame 2 is 448mm, which is the width of a standard 19-inch chassis. A plurality of placement intervals 201 are provided in the outer frame 2, so that at least two 21-inch servers can be placed. Of course, placing one server is also possible. For a 21-inch server, its height can be 1U, 2U or others. The height dimension of a 21-inch server is equal to the width dimension of the placement interval 201, and the corresponding placement interval 201 can be adapted in combination with the actual height of the 21-inch server. U can be specifically a standard 45mm, 46.5mm, 48mm or others, and the U height can be customized according to actual needs without restriction.

[0083] In this embodiment, by vertically placing a relatively large-sized server 3 into the placement interval 201, and using the height dimension of the placement interval 201 to meet the placement requirements of the large-sized server 3 in the width direction, the large-sized server can be placed in the cabinet 1 of the small-sized server. When the central processing unit with full memory channels is laid out, even if a larger-sized chassis is replaced to meet the layout requirements, the small-sized cabinet 1 corresponding to the smaller-sized chassis can be directly used, without replacing the existing cabinets in the computer room or building a new data center, which is conducive to the diversification of customer server design and the normalization of the data center. Specifically, it can be realized that a 21-inch server chassis can be placed in a 19-inch server cabinet.

[0084] Based on the above embodiments, please refer to Figure 1 , Figure 3 The two side walls of the cabinet 1 in the width direction are provided with support rails 101, and the support rails 101 are at least supported at the bottom of the outer frame 2 in the height direction, and the outer frame 2 and the support rails 101 are slidably connected. The width direction of the cabinet 1 here specifically refers to Figure 1 As indicated by W.

[0085] In a specific embodiment, two side walls in the width direction of the cabinet 1 are provided with strip-shaped rails 101. When the outer frame 2 is disassembled relative to the cabinet 1, the outer frame 2 can be pulled or pushed so that the outer frame 2 can slide relative to the rails 101 to achieve the effect of convenient disassembly and assembly. The effect that the strip-shaped rails 101 can achieve is to support the bottom of the outer frame 2, so that when the outer frame 2 is relatively fixed on the rails 101, the outer frame 2 and the large-sized server 3 inside it have better stability.

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

[0087] In the above two specific implementations, it should be noted that after the outer frame 2 slides into place relative to the support rail 101, the outer frame 2 and the support rail 101 still need to be fixed with the help of fasteners, and the specific fasteners can be screws.

[0088] On the basis of any of the above embodiments, one end of the outer frame 2 away from the extension piece 4 is a plug-in interface, and the plug-in interface is used for plugging and unplugging the large-size server 3 relative to the outer frame 2. The plug-in interface here is based on the outer frame 2 being a frame-type structure, and the specific size is consistent with the size of the inner cavity of the outer frame 2. The large-size server 3 can be inserted into the placement interval 201 from the position of the plug-in interface, and can also be pulled out from the placement interval 201 to move the large-size server 3 out of the plug-in interface.

[0089] Both sides of the plug interface are provided with folded edges 202, the folded edges 202 extend in a direction away from the placement interval 201, and the folded edges 202 on both sides of the plug interface correspond to the two side walls in the width direction of the connecting cabinet 1. Figure 4 The height direction of the folded edge 202 is provided with screw holes for correspondingly connecting the folded edge 202 and the square hole bars on both sides of the cabinet 1. A plurality of screw holes may be provided. The width direction and the height direction are respectively as follows: Figure 1 and Figure 4 W and H in the middle indicate.

[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 between the outer frame 2 and the support rail 101, when the outer frame 2 slides into place, the folded edge 202 is fixedly connected to the cabinet 1 to achieve the fixation of the outer frame 2 relative to the cabinet 1, so that the outer frame 2 and the large-size server 3 arranged therein have better stability and reliability.

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

[0092] Based on 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 to ensure the structural strength of the outer frame 2. In this case, the height of the corresponding placement interval 201 is not adjustable, and is directly designed according to the width of the actual corresponding large-size server 3, so that large-size servers 3 of different standards can be installed in the cabinet 1 corresponding to the small-size server. The different standards here include but are not limited to the Scorpio standard and the OCP standard industry standard.

[0093] Based on any of the above embodiments, please refer to Figure 4The outer frame 2 includes an outer frame body 206, a cover plate 205 that can move along the height direction of the outer frame body 206, and the top of the outer frame body 206 has an opening. 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 the large-size servers 3 of different specifications, 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 set on the cover plate 205 and / or the outer frame body 206 to increase the structural strength, so as to prevent the outer frame 2 from shaking unsteadily and affecting the stable operation of the large-size server inside.

[0094] Specifically, the cover plate 205 can move along the height direction of the outer frame body 206, and the specific setting method is not limited. Specifically, the cover plate 205 can move 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 slides into place, it needs to be fixed to the outer frame body 206 with the help of fasteners to ensure the reliable connection between the cover plate 205 and the outer frame body 206, so as to ensure the overall reliability and stability of the outer frame 2. In this case, the specific folding edge 202 is set on the outer frame body 206 to facilitate the connection with the cabinet 1.

[0095] Based on any of the above embodiments, please refer to Figure 5 , the outer wall of the extension piece 4 is connected to the inner wall of the outer frame 2, and the extension piece 4 has an extension section 401 connected to the placement section 201. The extension piece 4 is provided with an opening in the circumference, and the opening is provided corresponding to the placement section 201, so that the extension section 401 of the extension piece 4 can be connected to the placement section 201, so as to achieve the effect of changing the length of the placement section 201, and improve the applicability of the conversion device. Specifically, if the large-size server 3 is a 21-inch server, the overall size of the 21-inch server has different standards, such as the OCP standard and the Scorpio standard. The length value corresponding to the 21-inch server may be between 780 and 900 mm, or may be 900 mm, or may be 920 mm. By providing the extension section 401, the length of the placement section 201 can have a space that can be extended to suit the different lengths of the large-size server 3.

[0096] The extension piece 4 is provided with a plurality of rows of mounting holes 402 in the length direction, and each row of mounting holes 402 can be connected to the fixing holes 204 of the outer frame 2.
