Description

Technical Field

[0001] The present disclosure relates to the field of computer technology, and in particular to an immersion liquid cooling cabinet and a cabinet assembly method. Background Art

[0002] In recent years, with the continuous development of Internet technology, the information technology fields such as computers, networks, and communications have placed higher and higher requirements on the integration of electronic devices, and the requirements for heat dissipation of highly integrated electronic devices have become higher and higher. In order to achieve higher heat dissipation efficiency, liquid cooling technology has gradually been applied to various electronic devices and peripheral equipment related to electronic devices (such as cabinets).

[0003] In the related art, cabinets that use liquid cooling technology usually adopt a vertical wiring solution, that is, the cables need to be laid vertically in the cabinet after the equipment is put on the rack. Therefore, in the related art, the cables need to be laid after all the equipment in the cabinet is put on the rack, and the implementation process is fixed; and the wiring time in the cabinet is long, resulting in the cover being opened for a long time, and the inside of the cabinet, such as the liquid inside, is exposed to the outside for a long time, thereby causing liquid or cabinet contamination; or, due to various factors such as personnel tools, liquid or cabinet contamination may also be caused.

[0004] Therefore, the vertical wiring solution applied to the cabinet has a long cable deployment time and low efficiency; at the same time, the long wiring process has a high risk of causing pollution to the inside of the cabinet, which has an adverse effect on the stability of the overall operation of the cabinet. Summary of the invention

[0030] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0031] Before explaining the immersion liquid cooling cabinet and the cabinet assembly method provided by the embodiments of the present disclosure, the terms that may be involved in the embodiments of the present disclosure are first explained.

[0032] Immersion liquid cooling: a heat dissipation technology; in an immersion liquid cooling cabinet, servers and switches are deployed in a special liquid. The heat generated by the operation of the server and switch can be removed through the circulation of the liquid.

[0033] Tank: Cabinet, equivalent to the cabinets in traditional air-cooled data centers, used to accommodate switches and servers.

[0034] DAC: Direct Attach Cable, directly connected cable, refers to the cable between the switch and the server; it can be a special transmission cable with modules at both ends and a cable in the middle.

[0035] ASW: Access layer switch; data exchange module access layer switch, access to cloud server, uplink interconnection core switch DSW;

[0036] DSW: Distribution layer switch; core switch, used to connect various ASW access layer switches.

[0037] PSW: Ethernet switch; used for Ethernet network communication between device layers.

[0038] OAW-S: Out-of-band switch; responsible for IP configuration and other tasks for the server.

[0039] Pre-deployment: that is, prefabricated deployment, which is a new integrated wiring method under immersion liquid cooling, which improves the efficiency of cable deployment in the cabinet and increases the overall operation stability of the cabinet.

[0040] The immersion liquid cooling cabinet provided by the embodiments of the present disclosure can be configured in a data center, a network wiring room, a floor wiring room, a central computer room, a data computer room, a control room and a control center, or applied to other scenarios that require pre-deployment of cables in the cabinet, which is not limited here. Exemplarily, when the immersion liquid cooling cabinet is applied to any of the above scenarios, the cables between the switch and the server can be pre-deployed using a pre-deployed cable management rack, and the pre-deployed cable management rack is connected to the cabinet body after the cables are pre-deployed, which can reduce the time for deploying cables in the cabinet and improve the wiring efficiency; at the same time, it reduces the time to open the cabinet cover and the time the interior of the cabinet and the liquid therein are exposed, reduces pollution to the interior of the cabinet, improves the safety of the operation of the equipment in the cabinet, and is conducive to the overall stable operation of the cabinet. Exemplarily, when the immersion liquid cooling cabinet is used for cable deployment, the integrated solution for implementing the integrated wiring of the cabinet can be divided into two parts: internal wiring of the cabinet and external wiring of the cabinet. The interface between the two parts of the wiring is that the flange-terminated equipment (including servers and switches) is deployed on the outside of the cabinet. The ASW switch inside the cabinet is connected to the lower end port of the flange, and the PSW switch outside the cabinet is connected to the upper end port of the flange. Exemplarily, the internal wiring of the cabinet includes the deployment of cables such as DAC, power cables, and network cables that need to be immersed in liquid, and the material composition of all cables is strictly prohibited from containing plasticizers.

[0041] Compared with the wiring scheme in the related art, in the cabinet and its assembly method provided by the embodiment of the present disclosure, a detachable pre-deployed cable management rack is set in the cabinet. By using the pre-deployed cable management rack to pre-deploy the cables between the switch and the server, it is equivalent to pre-positioning the cable laying work in the cabinet, improving the efficiency of cable deployment in the cabinet, and solving the cable positioning problem at the same time, and improving the accuracy between the switch port and the corresponding cable. In addition, the embodiment of the present disclosure provides a length reserved binding tool. The tool is used to reserve the length, so as to realize the precise vertical laying of cables without the physical switch in the detachable pre-deployed cable management rack, which is equivalent to proposing a new cable laying rule and standard outside the cabinet.

[0042] Combined with the following Figure 1-Figure 11 , an immersion liquid cooling cabinet, a cabinet assembly method, and a length reservation binding tool provided in an embodiment of the present disclosure are exemplarily described.

[0043] like Figure 1 As shown, the immersion liquid cooling cabinet (hereinafter referred to as "cabinet") 10 provided in the embodiment of the present disclosure may include: a cabinet body 110 and a pre-deployed cable management rack 120; the cabinet body 110 is used to accommodate switches and servers; the pre-deployed cable management rack 120 is detachably connected to the cabinet body 110 and is used to pre-deploy cables between switches and servers.

[0044] In the embodiment of the present disclosure, the cabinet 110 can be used to accommodate switches and servers. The specific accommodation method of the switches and servers can be set based on the needs. Figure 2 and Figure 3 An exemplary description is given.

[0045] In the disclosed embodiment, the pre-deployed cable management rack 120 can be used to pre-deploy cables between switches and servers, that is, the pre-deployed cable management rack 120 can pre-deploy cables between switches and servers directly based on the relative spatial positions of the servers and switches in the absence of physical switches and servers.

[0046] Based on this, by directly assembling the pre-deployed cable management frame 120 after the cables between the pre-deployed switch and the server with the cabinet 110, it is equivalent to directly connecting the pre-deployed cable management frame 120 with pre-wired cables to the cabinet 110, thereby reducing the time for deploying cables in the cabinet.

[0047] In the immersion liquid cooling cabinet 10 provided in the embodiment of the present disclosure, the immersion liquid cooling cabinet 10 is provided with: a cabinet body 110 and a pre-deployed cable management rack 120; the cabinet body 110 accommodates switches and servers; the pre-deployed cable management rack 120 is detachably connected to the cabinet body 110 and is used to pre-deploy cables between the switches and the servers. The pre-deployed cable management rack 120 can be used to pre-deploy cables between the switches and the servers. After the cables are pre-deployed, the pre-deployed cable management rack 120 is connected to the cabinet body 110, which can reduce the time for deploying cables in the cabinet 10 and improve the wiring efficiency; at the same time, it reduces the time for opening the cover of the cabinet 10 and the time for the interior of the cabinet 10 and the liquid therein to be exposed, reduces the pollution to the interior of the cabinet 10, is beneficial to improving the operating stability and safety of the switches and servers, and thus is beneficial to improving the overall operating safety and stability of the cabinet 10.

[0048] In an optional embodiment of the present disclosure, Figure 2-Figure 5 As shown, the cabinet 10 includes a plurality of accommodating units (indicated by U numbers, also referred to as "U-bit numbers", which are numbered in Arabic numeral sequence) for accommodating switches (including ASW master, ASW standby and OAW-S) and servers (i.e., Server); the pre-deployed cable management frame 120 includes a cable outlet hole 122, which is respectively arranged corresponding to each accommodating unit.

[0049] In the embodiment of the present disclosure, the accommodating units are sequentially arranged in the cabinet 110 for accommodating switches and servers; corresponding cable outlet holes 122 are arranged in the pre-deployed cable management rack 120, and the cable outlet holes 122 can allow the pre-deployed cables in the pre-deployed cable management rack 120 to extend out so that the cables can be connected to the servers and switches in the corresponding accommodating units.

[0050] Exemplarily, after the cabinet 10 is assembled, the cable outlet holes 122 correspond to the positions of the accommodating units, respectively, so that the cables extending from the pre-deployed cable management rack 120 can be easily and conveniently connected to the corresponding servers and switches. The connection method is simple and convenient, which is conducive to saving the time used to connect the cables to the server and switch, thereby helping to improve the efficiency of cable deployment.

[0051] In the disclosed embodiment, the cabinet 10 includes accommodating units for accommodating servers and switches, and the pre-deployed cable management frame 120 includes cable outlet holes 122 respectively arranged corresponding to each accommodating unit. This facilitates the corresponding connection between the pre-deployed cables in the pre-deployed cable management frame 120 and the switches and servers accommodated in the cabinet 110. The connection method is simple and convenient, which is conducive to saving cable deployment time, improving cable deployment efficiency, and thereby reducing the risk of contamination inside the cabinet, thereby improving the overall operating safety and stability of the cabinet.

[0052] In an optional embodiment of the present disclosure, Figure 2 and Figure 3 As shown, the accommodating unit includes at least one of a main switch accommodating unit, a standby switch accommodating unit, an out-of-band switch accommodating unit and a server accommodating unit. The main switch accommodating unit is used to accommodate a main access layer switch (shown as ASW-main), the standby switch accommodating unit is used to accommodate a standby access layer switch (shown as ASW-standby), the out-of-band switch accommodating unit is used to accommodate an out-of-band switch (shown as OAW-S), and the server accommodating unit is used to accommodate a server (shown as 1UServer); wherein the out-of-band switch accommodating unit is located between the main switch accommodating unit and the standby switch accommodating unit. The server accommodating units are respectively arranged on a side of the main switch accommodating unit away from the out-of-band switch accommodating unit, and on a side of the standby switch accommodating unit away from the out-of-band switch accommodating unit; correspondingly, the cable outlets include switch cable outlets and server cable outlets, the switch cable outlets are respectively arranged corresponding to the main switch accommodating unit, the standby switch accommodating unit and the out-of-band switch accommodating unit, and the server cable outlets are respectively arranged corresponding to the server accommodating units; wherein the switch cable outlets and the server cable outlets are respectively used to allow cables connecting the switch and the server to extend out.

[0053] In the disclosed embodiment, a single cabinet is equipped with two access layer switches and one out-of-band switch, and both are arranged at the center of the cabinet, with servers connected thereto arranged radiating to both ends; correspondingly, corresponding accommodating units are arranged in the cabinet, so that in the accommodating units of the cabinet, the switch accommodating units (including the main switch accommodating units, the standby switch accommodating units, and the out-of-band switch accommodating units) are all arranged in the middle of the server accommodating units, that is, the server accommodating units are arranged on both sides of the switch accommodating units. Corresponding to the spatial positions of the accommodating units in the cabinet, in the pre-deployed cable management rack, the cable outlets include switch cable outlets and server cable outlets, and the server cable outlets are arranged on both sides of the switch cable outlets, respectively corresponding to the accommodating units for accommodating the corresponding devices, so that the connection between the cables and the corresponding servers and switches can be achieved by using a smaller cable length.

[0054] For example, Figure 2 and Figure 3 In the figure, a 54U standard cabinet is used as an example to illustrate the configuration of servers and switches. The access layer switch is placed in the middle of the cabinet, the main access layer switch (shown as ASW-main) is placed at the 26U position, the standby access layer switch (shown as ASW-standby) is placed at the 29U position, and the out-of-band switch (shown as OAW-S) is placed at the 28U position. 24 1U servers are placed on both sides of the switch, for a total of 48 1U servers.

[0055] In other embodiments, when the cabinet adopts other sizes, other methods known to technical personnel in this field can also be used to configure the server and switch, and the accommodating units in the cabinet and the cable outlet holes in the pre-deployed cable management rack are set accordingly, which is not limited here.

[0056] For example, in Figure 2 Based on Figure 3 The cables 011 connected between the server and the switch are respectively arranged in a cross manner to both sides by the pre-deployed cable management rack with the positions of the respective switches as the center, and the cables are output at the positions of the corresponding servers, thereby realizing the pre-deployment of the cables.

[0057] It is understandable that the above embodiments only show different accommodating units by the number U, but do not constitute a limitation on the cabinet provided in the embodiment of the present disclosure. In other embodiments, other methods known to those skilled in the art may be used to identify the accommodating units, which are not limited here.

[0058] In the embodiment of the present disclosure, the switch accommodating unit is located at the center of the cabinet, and the server accommodating units are symmetrically arranged on both sides of the switch accommodating unit; correspondingly, in the cable outlet holes of the pre-deployed cable management rack, the switch cable outlet holes are located at the center of the pre-deployed cable management rack, and the server cable outlet holes are symmetrically arranged on both sides of the switch cable outlet holes, so that the cables between the server and the switch can be pre-deployed while making the cable deployment more regular and the cable management more convenient; and the cables are more symmetrical in the areas on both sides of the switch cable outlet holes in the pre-deployed cable management rack, so that the space occupied by the cables on both sides of the switch cable outlet holes in the pre-deployed cable management rack is equivalent, which is beneficial to improving the utilization rate of the internal space of the pre-deployed cable management rack, and further beneficial to realizing the small size design of the cable management rack.

[0059] In an optional embodiment of the present disclosure, Figure 5 As shown, a three-layer fixing structure 124 is provided on one side of the pre-deployed cable management frame 120 to fix cables connected to the out-of-band switch, cables connected to the main access layer switch, and cables connected to the backup access layer switch, respectively.

[0060] In the disclosed embodiment, the cables corresponding to the switch positions are divided into three types, namely, cables connected to the main access layer switch, cables connected to the backup access layer switch, and cables connected to the out-of-band switch. Among them, since it is necessary to pre-deploy the cables between the server and the switch in the pre-deployed cable management rack 120 in the absence of physical switches and servers, in order to ensure that the cable sequence can be maintained without being messy after the cables are pre-deployed, a three-layer fixed structure 124 is set on one side of the pre-deployed cable management rack 120 to respectively fix the cables connected to the out-of-band switch, the cables connected to the main access layer switch, and the cables connected to the backup access layer switch, so as to facilitate the cables to be plugged into the corresponding out-of-band switch, the main access layer switch, the backup access layer switch, and the corresponding server during the cabinet assembly process, thereby saving time and improving wiring efficiency.

[0061] Exemplarily, the structure of the fixing structure 124 can be a binding buckle. In the disclosed embodiment, three binding buckles are arranged on the rear side of the pre-deployed cable management rack, which are used to bind cables connected to the out-of-band switch, cables connected to the main access layer switch, and cables connected to the backup access layer switch; wherein the cables connected to the out-of-band switch are bound at the bottom layer, the cables connected to the backup access layer switch are bound at the middle layer, and the cables connected to the main access layer switch are bound at the top layer, so as to realize the layered fixing of the three different cables.

[0062] It is understandable that the above only uses the binding buckle as an example to illustrate the fixing structure. In other embodiments, other structural forms or spatial arrangement forms of fixing structures can also be used to fix the pre-deployed cables in the pre-deployed cable management rack based on other cable grouping methods, which is not limited here.

[0063] In the disclosed embodiment, by setting up a pre-deployed cable management rack on one side including a three-layer fixed structure for fixing cables connected to the out-of-band switch, cables connected to the main access layer switch, and cables connected to the backup access layer switch, the position of each cable can be made clear, which is beneficial to saving time for connecting the cables to the corresponding servers and switches during the cabinet assembly process, thereby saving time and improving the cabinet assembly efficiency.

[0064] In an optional embodiment of the present disclosure, the front scale of the pre-deployed cable management rack is further provided with an auxiliary fixing structure; the auxiliary fixing structure corresponds to the position of each accommodating unit, and is used to adjustably fix the cables corresponding to the position of the same accommodating unit.

[0065] In the disclosed embodiment, an auxiliary fixing structure is provided on the front scale of the pre-deployed cable management rack, and the position of the auxiliary fixing structure corresponds to the position of the accommodating unit, so as to achieve adjustable fixing of the cables at the same accommodating unit position, that is, the position of the cable is fixed, but its length is still adjustable. With such a setting, while achieving a relatively fixed position of the cable, which is convenient for connecting the corresponding ports of the corresponding server and switch, the length of the cable outlet can be adjusted to an appropriate length that can connect to the port but is not too long, so that the length tolerance is large, which is conducive to realizing on-demand wiring based on the spatial position in the cabinet and improving wiring efficiency.

[0066] Exemplarily, the auxiliary fixing structure can be a binding buckle. In combination with the above, three groups of cables (i.e., cables connected to the out-of-band switch, cables connected to the main access layer switch, and cables connected to the backup access layer switch) at the same U-position fixed position can be uniformly bound to the binding buckle of the front scale of the pre-deployed cable management rack; and the switch side uniformly reserves the cable length based on the statistical socket position of each outlet U-position.

[0067] Exemplarily, the auxiliary fixing structure may further include a magic tie. In combination with the above, in the pre-deployed cable management rack, the cables corresponding to the single U position of the cabinet are uniformly tied to the same position using a magic tie to facilitate fine-tuning of the length of the cables after they are plugged in.

[0068] It is understandable that the above only uses the binding buckle as an example to illustrate the auxiliary fixing structure. In other embodiments, the employer fixing structure of other structural forms or spatial arrangements can also be used to achieve unified fixing of the pre-deployed cables corresponding to the same accommodation unit in the pre-deployed cable management rack, which is not limited here.

[0069] In the disclosed embodiment, a cabinet is provided including a cabinet body and a pre-deployed cable management rack, so that cables between servers and switches can be pre-deployed on the outside of the cabinet body by using the cable management rack, thereby eliminating the need for long-term vertical deployment of cables inside the cabinet body, which is beneficial to shortening the time required for deploying cables inside the cabinet, reducing the risk of liquid or cabinet contamination caused by long-term exposure inside the cabinet and long-term human operation inside the cabinet, and is beneficial to improving the overall operational stability and safety of the equipment and the cabinet; at the same time, since the corresponding cable deployment operation can be performed before the equipment inside the cabinet is put on the shelf, or synchronously with the putting on the shelf, the delivery time after the equipment is put on the shelf is greatly shortened.

[0070] The disclosed embodiment also provides a cabinet assembly method for assembling an immersion liquid-cooled cabinet; wherein the structure of the immersion liquid-cooled cabinet may be any of the structures provided in the above-mentioned embodiments, and includes a cabinet body and a pre-deployed cable management rack. By pre-deploying cables connecting servers and switches in the pre-deployed cable management rack, and directly assembling the pre-deployed cable management rack with the cabinet body, the time for deploying cables in an exposed state inside the cabinet can be reduced, thereby improving the cable deployment efficiency. At the same time, by shortening the cable deployment time, the risk of contamination of liquid and other components inside the cabinet can be reduced, which is beneficial to improving the overall operating stability and safety of the equipment and cabinet.

[0071] In an optional embodiment of the present disclosure, Figure 6 As shown, the cabinet assembly method may include the following steps:

[0072] S501: Determine location information of servers and switches in a cabinet.

[0073] In the embodiment of the present disclosure, the position information is information used to indicate a spatial position.

[0074] In the disclosed embodiment, the cabinet is used to accommodate the server and the switch, and the server and the switch are connected by cables. The location of the server and the switch determines the length and the outlet position of the cable. Therefore, in order to realize the pre-deployment of the cable, it is necessary to first determine the location information of the server and the switch in the cabinet.

[0075] For example, in combination with the above Figure 2 and Figure 3 , the location information of the server and the switch can be represented by the number U. You can refer to the above for understanding, and will not repeat it here.

[0076] It can be understood that the location information of the server and the switch may also be represented by spatial coordinates or other forms known to those skilled in the art, which are not limited here.

[0077] S502: Based on the location information, deploy cables between the switch and the server in a pre-deployed cable management rack.

[0078] In the disclosed embodiment, the cables in the pre-deployed cable management rack are used to connect the switch and the server. After the positions of the switch and the server are determined in the aforementioned S501, in this step, the cables can be deployed in the pre-deployed cable management rack outside the cabinet based on the positions of the switch and the server.

[0079] For example, in combination with the above, after the number of U-bits of switches and servers is confirmed, the pre-deployed cable management rack can be moved horizontally outside the cabinet for cable deployment with the switch as the center. For example, network cables and DACs of corresponding U-bit lengths are preferentially deployed outside the cabinet, that is, prefabricated cable deployment is performed.

[0080] It is understandable that, in addition to meeting the corresponding U-position length, the pre-deployed cables can also reserve a certain length of outgoing cables to effectively connect the server and the switch, which is exemplified in the following text.

[0081] S503, assembling the pre-deployed cable management rack and the cabinet after the pre-deployed cables are assembled.

[0082] In the disclosed embodiment, the pre-deployed cable management rack that has completed the pre-deployment process of the cables is assembled with the cabinet, eliminating the need for long-term vertical deployment of the cables inside the cabinet, thereby shortening the time for deploying the cables inside the cabinet.

[0083] For example, Figure 7 As shown, after the cable pre-deployment is completed, the cover of the pre-deployed cable management rack is pushed into the positioning column along the direction indicated by the arrow in the figure and fixed, for example, by snapping the thumb positioning column 022, or by other structures or methods, which are not limited here. Afterwards, the pre-deployed cable management rack and the pre-deployed cables therein are moved as a whole into the cabinet, and fixed to the cabinet using the fixing bolts of the pre-deployed cable management rack, such as Figure 8 .

[0084] It can be understood that the pre-deployed cable management rack can be detachable and fixed to the cabinet.

[0085] In other embodiments, an easily detachable snap-on fastener (referred to as a "fastener") may be provided at each end and the middle of the pre-deployed cable management rack. After the pre-deployed cable management rack and the pre-deployed cables therein are moved into the cabinet, the pre-deployed cable management rack and the cabinet may be assembled by installing the fastener.

[0086] In other embodiments, other methods known to those skilled in the art may be used to achieve the assembly of the pre-deployed cable management rack and the cabinet, which is not limited here.

[0087] For example, taking the liquid-cooled cabinet Kylin 3.0 server as an example, in the related art, it usually takes 4 hours for a single cabinet and a single team of personnel to deploy cables. However, in the assembly solution provided by the embodiment of the present disclosure, a cable pre-deployment solution is adopted, which can only take 2 hours for a single cabinet and a single team of personnel to deploy cables, shortening the time by half.

[0088] In the assembly method of the cabinet provided by the embodiment of the present disclosure, by pre-deploying cables between switches and servers based on the location information of servers and switches in the pre-deployed cable management frame, the pre-deployment of cables outside the cabinet is realized. Thereafter, by assembling the pre-deployed cable management frame and the cables therein with the cabinet, it is equivalent to directly combining the pre-deployed cable management frame with deployed cables with the cabinet, thereby reducing the time for deploying cables in the cabinet, reducing the exposure time of the interior of the cabinet, reducing the risk of contamination of the cabinet and the liquid therein, and facilitating the safe and stable operation of the equipment and the cabinet as a whole. At the same time, after the equipment is put on the shelf, the equipment can be directly connected by cable, and the cable length can be fine-tuned, thereby shortening the cable deployment time, shortening the delivery time after putting on the shelf, and improving the delivery efficiency.

[0089] In an optional embodiment of the present disclosure, Figure 6 On the basis of, before S503, the method may further include a step of putting equipment on a shelf, namely:

[0090] Place the switch and server in the cabinet.

[0091] In the embodiment of the present disclosure, the switch includes at least one of a main access layer switch, a backup access layer switch and an out-of-band switch; the server includes a first group of servers and a second group of servers of equal number; the out-of-band switch is arranged between the main access layer switch and the backup access layer switch, the first group of servers is arranged on the side of the main access layer switch away from the out-of-band switch, and the second group of servers is arranged on the side of the backup access layer switch away from the out-of-band switch, as can be seen above Figure 2 or Figure 3 .

[0092] In the disclosed embodiment, before assembling the pre-deployed cable management rack and the cabinet, it is also necessary to place the equipment on the rack, that is, place the switch and the server in the corresponding accommodation unit of the cabinet to complete the placement of the switch and the server in the cabinet.

[0093] Therefore, after the cables are pre-deployed in the pre-deployed cable management frame, after the cabinet is in place and leveled, and the server and switch are installed, the pre-deployed cable management frame and the pre-deployed cables therein are moved as a whole into the cabinet for assembly.

[0094] Based on this, after S503, the method may further include a cable plugging step, namely:

[0095] Connect the switch and server using pre-installed cables.

[0096] In the disclosed embodiment, after the pre-deployed cable management rack is assembled with the cabinet, the pre-deployed cables in the pre-deployed cable management rack are used to connect the corresponding switches and servers to achieve the connection between the server and the switch in the cabinet, and perform process fixing and fine-tuning.

[0097] In the embodiment of the present disclosure, before assembling the pre-deployed cable management rack and the cabinet, the switches and servers are placed on the rack, that is, they are placed in the corresponding accommodation units in the cabinet; and after assembling the pre-deployed cable management rack and the cabinet, the pre-deployed cables are connected to the corresponding servers and switches to achieve electrical connection and communication connection.

[0098] In other implementations, the device listing may be performed simultaneously with S502 , or the device listing may be performed after S502 , which is not limited here.

[0099] In an optional implementation of the present disclosure, the cable includes at least one of a direct connection cable, a network cable, and a power cable.

[0100] In the embodiment of the present disclosure, the direct connection cable is DAC, and the terminology has been explained in the previous text and will not be repeated here. The network cable is used to transmit network signals, and the power cable is used to provide power supply signals.

[0101] In other implementations, the cable may also include other types of cables connecting a switch and a server, which are not limited here.

[0102] Based on this, Figure 6 On the basis of, S502 may specifically include:

[0103] In the pre-deployed cable management rack, for directly connected cables and / or network cables, the cables are arranged in a bifurcated manner along the arrangement direction of the servers on both sides, with the switches to which they are connected as the center, and the cables are connected at the positions corresponding to the server connections to be plugged into the ports of the server.

[0104] In the disclosed embodiment, when pre-deploying cables in a pre-deployed cable management rack, based on the relative positions of the switch and the server, the cables are managed in a cross manner to both sides with the switch as the center, and the cables are brought out at positions corresponding to the connection servers to ensure that the cables are plugged into the ports of the corresponding servers, and to facilitate even distribution of the cables after plugging, without entanglement or crossing between the cables.

[0105] After the pre-deployed cable management rack is assembled with the cabinet, the outgoing cables are plugged into the corresponding ports of the server, and the cables are evenly distributed in the cabinet after plugging, without any entanglement or crossing between the cables, thus ensuring that the cables are clearly organized and easy to find; at the same time, since there is no entanglement or crossing between the cables, the signal impact between different cables is small, and the signal accuracy is high.

[0106] In the disclosed embodiment, by setting up the pre-deployment method of cables in the pre-deployed cable management rack, the pre-deployed cables and the cables after connecting the server and the switch in the cabinet are clearly organized and easy to find; the signal interference between them is small and the signal accuracy is high.

[0107] In an optional implementation of the present disclosure, the outgoing lengths of the cables at locations corresponding to the respective servers are the same, that is, all are unified.

[0108] In the disclosed embodiment, the cable outlet length is the length of the cable extending out of the pre-deployed cable management frame, which is equal to the cable length between the pre-deployed cable management frame and the port of the server, is related to the distance between the two, and depends on the model of the server.

[0109] For example, take the cable length between the pre-deployed cable management rack applicable in the liquid-cooled cabinet Kylin 3.0 server to the corresponding server port as an example: the port may include a network cable plug-in port, such as RJ45; it may also include 4 direct connection cable plug-in ports, such as optical port 0, optical port 1, optical port 2 and optical port 3; among which, the outgoing line length corresponding to RJ45 is 210mm, the outgoing line length corresponding to optical port 0 is 180mm, the outgoing line length corresponding to optical port 1 is 200mm, the outgoing line length corresponding to optical port 2 is 220mm, and the outgoing line length corresponding to optical port 3 is 240mm.

[0110] It can be understood that in other embodiments, the cable outlet length corresponding to each server can be determined based on the distance between the pre-deployed cable management rack and the server port, and can be set based on the requirements of the cabinet and its assembly method, which is not limited here.

[0111] In the embodiment of the present disclosure, by setting the outgoing cable lengths of the cables corresponding to the locations of the servers to be uniform, the regularity of cable deployment can be increased, which is conducive to simplifying the cable deployment process.

[0112] In an optional implementation of the present disclosure, the length of the cable in the pre-deployed cable management rack is equal to the straight-line distance between the corresponding connected switch and the server.

[0113] In the disclosed embodiment, the length of the cable in the pre-deployed cable management rack, i.e., the length of the cable within the space defined by the pre-deployed cable management rack and not extending outside the pre-deployed cable management rack, is equal to the straight-line distance between the switch and the corresponding connected server, and the pre-deployed cable is arranged roughly straight in the pre-deployed cable rack. In combination with the above, the length of the cable in the pre-deployed cable management rack may be the U-position length between the corresponding accommodation units for placing the switch and the server. In other embodiments, the length may also be characterized by length units, such as centimeters or millimeters, etc., which are not limited here.

[0114] In the disclosed embodiment, by setting the length of the cables in the pre-deployed cable management rack equal to the straight-line distance between the corresponding connected switch and the server, the pre-deployed cables can be arranged straight in the pre-deployed cable management rack, with clear organization, and are not easily entangled with each other, and the signal interference between them is small.

[0115] In other embodiments, the length of the cable in the pre-deployed cable management rack may also be greater than the straight-line distance between the corresponding connected switch and server, so as to reserve sufficient adjustable length and realize flexible adjustment of the cable length.

[0116] In an optional embodiment of the present disclosure, Figure 6 On the basis of the above, the process of pre-deploying cables also includes:

[0117] Leave room for a bend between the server ports and the pre-deployed cable management arm.

[0118] In the disclosed embodiment, a reserved bend is provided between the port of the server and the pre-deployed cable management frame to achieve flexible plugging and length fine-tuning between the cable and the port of the server.

[0119] For example, taking the liquid-cooled cabinet Kylin 3.0 server as an example, without calculating the cable structure length, the reserved curvature of the cable can be increased by 5cm to 8cm on the basis of each length.

[0120] In other embodiments, when the method is applied to other types of liquid cooling cabinets and corresponding servers accommodated therein, the length range of the reserved curvature may also be other values ​​or value ranges, which are not limited here.

[0121] In the embodiment of the present disclosure, during the process of pre-deploying cables, a bend is reserved between the port of the server and the pre-deployed cable management frame, so as to facilitate fine adjustment of the length after the cables are plugged in, so as to ensure effective connection between the cables and the server.

[0122] In the cabinet assembly method provided by the embodiment of the present disclosure, the cable deployment operation can be performed in advance, that is, the cables in the pre-deployed cable management rack can be deployed before the equipment is put on the shelf, without having to wait until the equipment in the cabinet is put on the shelf before deploying the cables. Therefore, after the equipment is put on the shelf, it is only necessary to plug in the cables and fine-tune the length, so as to quickly assemble the complete cabinet, shorten the time used for implementing the delivery process, and realize the ability of rapid delivery.

[0123] At the same time, since there is no need to deploy cables vertically in the cabinet, the pre-deployment cable management and bundling processes that may cause internal contamination of the cabinet are carried out outside the cabinet. Only cable length adjustment and upstream operations are performed in the cabinet, and no construction waste or other possible pollution is generated. As a result, the time for deploying cables in the cabinet is shortened and efficiency is improved. At the same time, the risk of contamination inside the cabinet and the liquid in it caused by long-term exposure inside the cabinet is reduced, thereby improving the operating safety and stability of the equipment in the cabinet and the cabinet as a whole.

[0124] The embodiment of the present disclosure also provides a length-reserving binding tool, which is applied in the cable pre-deployment process in cabinet assembly.

[0125] In the embodiment of the present disclosure, during the implementation of cable pre-deployment, the switch port positions need to be unified. In order to ensure that the pre-deployed cable management rack and the pre-deployed cables therein can be quickly fine-tuned after being translated into the cabinet of the cabinet, a length reservation binding tool can be used to reserve the length on the switch side.

[0126] It can be understood that the length refers to the reserved length below the bend of the cable on the upper side of the switch, and the height is 3-5cm.

[0127] In an optional embodiment of the present disclosure, Fig. 9 As shown, the length reserved binding tool 30 includes two clamps 301 arranged opposite to each other, and an adjustable fixing member 302 for fixing the opposite ends of the clamps 301; an opening 303 with a preset recessed depth is arranged on the side of the clamp 301, and the opening is used for placing the cable; the adjustable fixing member 302 is used to respectively adjust the relative distance between the two clamps 301 at both ends to adjust the reserved length of the cable.

[0128] In the embodiment of the present disclosure, the clamping plate 301 includes a first clamping plate 3011 and a second clamping plate 3012 . The first clamping plate 3011 and the second clamping plate 3012 are arranged opposite to each other and are adjustably fixed by an adjustable fixing member 302 .

[0129] In the disclosed embodiment, the adjustable fixing member 302 may include a fixing rod 3021 and an adjusting member 3022 movable on the fixing member 3021. By adjusting the position of the adjusting member 3022 on the fixing member 3021, the position of the clamping plate 301 can be adjusted.

[0130] For example, the fixing member 3021 may be a screw or a threaded rod, and the adjusting member 3022 may be a nut; both ends of the clamping plate include holes for the screw (or threaded rod) to pass through, and the nut is screwed on the screw (or threaded rod) and is arranged on both sides of the clamping plate 301. By adjusting the position of the nut on the screw (or threaded rod), the relative distance between the two clamping plates 301 can be changed. In other embodiments, the adjustable fixing member 302 may also be implemented in other structural forms, which are not limited here.

[0131] In the disclosed embodiment, the opening 303 reserved on the side of the clamping plate 302 is used to place cables, and the openings opposite to each other of the two clamping plates 301 are used to clamp the same cable, so that different lengths of pre-deployed cables can be reserved by changing the relative distance between the two clamping plates 301.

[0132] Exemplarily, the preset recess depth of the opening 303 may be set based on the wire diameter of the cable, and may be any value or value range that meets the requirement of clamping the cable, which is not limited herein.

[0133] Exemplarily, the recessed depths of the openings 303 may be equal, or may be set within a certain depth range, which is not limited herein.

[0134] Exemplarily, the shapes of the openings 303 may be the same or different, which is not limited here.

[0135] Exemplarily, the clamping plate 301 may be a wooden board, an acrylic board or other boards, which are not limited here.

[0136] Exemplarily, in combination with the above, the length-reserved binding tool may include a tool for a network cable and a direct-connect cable (ie, DAC), the dimensions of which are shown in Table 1.

[0137] Table 1 Tool size table

[0138]

[0139] Among them, Tool 1 represents the binding tool used for reserving the length of the network cable, Tool 2 represents the binding tool used for reserving the length of the DAC, the opening size represents the recessed depth of the opening, the opening interval represents the distance between two adjacent openings, and the distance from the rack represents the distance from the last section of the opening to the pre-deployed cable management rack.

[0140] For example, Fig. 9 and Fig.10 Tool 2 is shown, Fig.11 Tool 1 is shown. Figure 9-11 , and Table 1, in the cabinet provided by the embodiment of the present disclosure, the RJ45 port of the out-of-band switch is 48 ports evenly distributed on both sides of the out-of-band switch, and the number of ports on a single side is 24, corresponding to Fig.11The number of openings in the switch is 24; the number of ports on the access layer switch (i.e. the switch to which the DAC is plugged) is 16 on one side, and 4 ports form a group, with a 2.9 cm interval in the middle of each group, and a 1.4 cm interval between two adjacent openings in each group.

[0141] That is, in an optional embodiment of the present disclosure, the length reserved binding tool may include two types, namely, a network cable reserved binding tool and a direct connection cable reserved binding tool; in the network cable reserved binding tool, the intervals between two adjacent openings are equal; in the direct connection cable reserved binding tool, every 4 openings form a group; the intervals between two adjacent openings in the same group are equal; the interval between two adjacent groups is greater than the interval between two adjacent openings in the same group.

[0142] In other embodiments, the clamping plate may be set to other sizes as long as it can meet the cable pre-deployment requirements of the corresponding cabinet, which is not limited here.

[0143] In the disclosed embodiment, a length reservation binding tool 30 is provided, which includes two clamping plates 301 arranged opposite to each other and an adjusting fixture 302 for adjusting the relative distance between the two clamping plates 301. The relative distance between the two ends of the two clamping plates 301 is adjusted by adjusting the fixing 302 to adjust the reserved length of the pre-deployed cables, thereby achieving accurate reservation of cables in a scenario without physical switches and servers, which is conducive to accurate vertical deployment of cables and improves cable deployment accuracy and efficiency.

[0144] In an optional embodiment of the present disclosure, Fig.10 or Fig.11 As shown, the angle between the extension direction X1 of the opening 303 and the extension direction X0 of the side of the clamping plate 301 is an acute angle.

[0145] In the disclosed embodiment, in order to enable the opening 303 to better clamp the cable and prevent the cable from slipping, the angle between the extension direction X1 of the opening 303 and the extension direction X0 of the side of the clamping plate 302 is set to be an acute angle.

[0146] Exemplarily, the acute angle may be 45°, 50°, 30°, 50° to 60°, or other angles or angle ranges, which are not limited herein.

[0147] For example, Fig.10 and Fig.11 Taking the direction shown in as an example, the extension direction X1 of the opening 303 and the extension direction X0 of the side of the splint 301 form an angle toward the right. In other embodiments, the extension direction X1 of the opening 303 and the extension direction X0 of the side of the splint 301 may also form an angle toward the left, which is not limited here.
