Description

Technical Field

[0001] This utility model belongs to the field of rack server testing technology, and in particular relates to a power supply module for testing rack servers, and a test rack for rack servers. Background Technology

[0002] With the increasing prevalence of rack-mount servers, centralized power supply rack-mount servers are increasingly moving towards liquid cooling and blind-plug design. Currently, nodes in centralized power supply rack-mount servers are typically powered by externally input 380V high-current three-phase AC power modules, providing 48~54V DC power to the rack-mount server.

[0003] Due to the dedicated power supply and liquid cooling connection structure of the rack-mount server, rack-mount server nodes must be used in a liquid-cooled server room with a rack. However, a typical rack is 0.6 meters wide, 1.2 meters long, and 2.2 meters high, making it impossible to place it on a laboratory test bench during testing. Furthermore, laboratory test benches generally do not provide a 380V high-current three-phase AC power interface, but only a 220V AC power interface. A 380V high-current three-phase AC power interface can only be provided in the server room area, and most laboratories do not have a rack-mount liquid-cooled testing environment.

[0004] In summary, limitations in rack size, power supply interfaces, and the liquid-cooled testing environment necessitate that rack-mounted nodes be placed in a dedicated environment for debugging, unlike ordinary servers which can be independently debugged on laboratory benches. This testing method is overly dependent on the environment, requiring multiple people to remotely share the same rack, potentially leading to interference between operations. It also does not support simultaneous power-on and signal measurement, making debugging and positioning during the design phase extremely inconvenient. Summary of the Invention

[0005] To address the problem that current testing of rack-mount servers is limited by power supply interface restrictions and cannot be conducted on experimental equipment, this utility model provides a power supply module for testing rack-mount servers.

[0006] To solve the above problems, firstly, the technical solution adopted by this utility model is a test power supply module for rack-mount servers, including a module housing;

[0007] The module housing contains a power board and several PSU power supplies;

[0008] Each PSU power supply input terminal is connected to an AC power input port, which is located on the module housing and is compatible with the power socket of the experimental machine.

[0009] The power board is equipped with CRPS connectors and integrated power traces. The CRPS connectors are connected to the output terminals of each PSU power supply and the integrated power traces. The other end of the integrated power traces is connected to a power supply cable.

[0010] The module housing is also equipped with a power clip connector.

[0011] The power clip connector is connected to the power supply cable. In this solution, by providing an AC power input port that matches the power socket of the experimental machine, the problem of the lack of a 380V high-current three-phase AC power interface for laboratory machines in the prior art is solved. This allows the entire rack server node to be tested on ordinary laboratory machines without relying on a specific computer room power environment, improving the flexibility and convenience of testing. Integrating the power board and several PSU power supplies into the module housing, and providing CRPS connectors, combined power cabling, and power clip connectors, not only achieves stable power supply and effective distribution, but also makes the power module structure compact, easy to install and maintain, reduces the complexity and failure risk of external wiring, and improves overall reliability and stability.

[0012] Preferably, the power board is also equipped with a BMC;

[0013] The BMC is connected to each PSU power supply via an I2C bus;

[0014] The BMC is connected to a PHY chip, which has a GE interface and is connected to an RJ45 management network port through the GE interface.

[0015] The RJ45 management port is located on the module casing. In this preferred embodiment, power management functions are implemented through the BMC, the PSU power supply status is managed through the I2C bus, and the RJ45 management port can be connected to a laboratory interactive machine and management host to achieve monitoring and management of the PSU power supply.

[0016] On the other hand, this application also provides a test cabinet for rack servers, including a cabinet shell, wherein the height of the cabinet shell is less than a set height threshold;

[0017] The cabinet housing has a front window, a rear window, a top cover, a bottom, and two side walls;

[0018] The cabinet housing contains a power module and several server nodes;

[0019] The power supply module is the test power supply module described in the first aspect;

[0020] The rear window is equipped with a copper busbar for power supply.

[0021] The power supply copper busbar is connected to the power clip connector and each server node.

[0022] Each AC power input port of the power module is connected to the power socket of the experimental platform via a power cable passing through the front window of the rack housing. This test rack for rack-mount servers uses the aforementioned power module for rack-mount server testing, combined with the power supply copper busbar located in the rear window, which can effectively provide a stable power supply to the server nodes inside the rack. It also solves the problems of power interface mismatch and unstable power supply in the laboratory, ensuring the normal operation of the server nodes in the laboratory environment. Furthermore, because the rack housing height is less than a set height threshold, its volume is significantly reduced compared to traditional racks, facilitating movement and placement in the laboratory environment. This solves the problem of racks being too large to be placed on laboratory platforms, allowing rack-mount server nodes to be independently debugged in the laboratory environment.

[0023] Preferably, vertical fixing brackets are provided on both side walls of the cabinet housing, and the vertical fixing brackets on the two side walls are arranged in pairs;

[0024] Each side wall has a vertical fixed bracket with a horizontal L-shaped bracket, and the horizontal L-shaped brackets of two side walls are arranged in a group facing each other.

[0025] The server nodes and power modules are mounted on a corresponding set of horizontal L-shaped brackets. In this preferred embodiment, the vertical fixed brackets and horizontal L-shaped brackets located on the two side walls of the cabinet housing allow for flexible adjustment and installation according to the different sizes and heights of the server nodes and power modules, supporting various specifications of equipment. The paired vertical fixed brackets and the oppositely positioned horizontal L-shaped brackets provide a stable support structure for the server nodes and power modules, reducing vibration and displacement during operation, lowering the risk of failure due to poor physical contact, and facilitating the installation and disassembly of the equipment.

[0026] Preferably, the server node is connected to an external air-hydraulic CDU;

[0027] Each server node is equipped with a water inlet and a water outlet;

[0028] The water inlet and outlet are connected to the external air-fluid CDU via pipes passing through the rear window of the cabinet housing. In this preferred embodiment, the water pipes of the liquid-cooled server node are directly connected to the water pipes of the external air-fluid CDU by manual connection, which is a simple liquid cooling connection method, enabling liquid cooling performance testing of the entire cabinet server node in a laboratory environment.

[0029] Preferably, the rear window is equipped with a blind-insertion manifold interface plate;

[0030] The inlet and outlet pipes are connected to the external air-fluid CDU via the blind-plug manifold interface plate. In this preferred embodiment, when the server node is used as a liquid-cooled blind-plug cabinet node, a blind-plug manifold interface plate can be installed on the rear window of the cabinet shell. The liquid-cooled server node is first inserted into the blind-plug manifold interface plate, and then the blind-plug manifold interface plate leads out the inlet and outlet pipes to the external air-fluid CDU. This allows the inlet and outlet pipes of the server node to be quickly and conveniently connected to the external air-fluid CDU without complicated alignment and installation operations. This improves the connection efficiency of the liquid cooling system, reduces the time and difficulty of manual operation, and also reduces the risk of failures such as leakage due to improper connection.

[0031] Preferably, the rear window is provided with a cable management tray;

[0032] Each server node is connected to the hub. In this preferred embodiment, when the server nodes are used as blind-plug rack nodes, the hub allows for backplane interface testing of the server nodes. The hub centrally manages and organizes the cables of each server node, avoiding cable clutter, reducing mutual interference and tangling, and improving the neatness and maintainability of the cabling inside the rack.

[0033] Preferably, the rear window is provided with transverse reinforcing ribs;

[0034] The power supply copper busbar is vertically arranged in the middle of the rear window and fixedly mounted on the reinforcing rib;

[0035] The blind-insertion manifold interface board includes a first blind-insertion manifold interface board and a second blind-insertion manifold interface board;

[0036] The first blind-plug manifold interface plate and the second blind-plug manifold interface plate are disposed opposite to each other on both sides of the power supply copper busbar and are fixedly disposed on the reinforcing rib;

[0037] The first blind-plug manifold interface board connects the liquid inlet of each server node to the water outlet of the external air-fluid CDU.

[0038] The second blind-insertion manifold interface board connects the liquid outlet of each server node to the water inlet pipe of the external air-liquid CDU.

[0039] The hub includes a first hub and a second hub;

[0040] The first and second hubs are positioned opposite each other on either side of the power supply copper busbar, with the first hub located between the first blind-plug manifold interface plate and the power supply copper busbar, and the second hub located between the second blind-plug manifold interface plate and the power supply copper busbar. In this preferred embodiment, the transverse reinforcing ribs in the rear window not only enhance the structural strength of the rear window, better supporting components such as the power supply copper busbar, blind-plug manifold interface plate, and hubs, but also improve the functionality and practicality of the entire cabinet by optimizing the space utilization of the rear window.

[0041] Preferably, the top cover of the cabinet housing is removable;

[0042] The RJ45 management port is located on the front window of the cabinet housing;

[0043] The spacing between two adjacent sets of horizontal L-shaped brackets is 1U in height. In this preferred embodiment, the top cover of the cabinet is removable, allowing direct access to the waveform quality of the topmost node for signal quality testing and troubleshooting. The RJ45 management port is located on the front window of the cabinet, facilitating connection and management with external network devices and enabling maintenance personnel to remotely monitor and manage power modules and other equipment. The 1U spacing between adjacent sets of horizontal L-shaped brackets conforms to standard server equipment installation dimensions, facilitating the installation and expansion using standardized server nodes and power modules, thus improving the cabinet's versatility and scalability.

[0044] Preferably, the cabinet shell has a width of 600mm, a length of 1200mm, and a diameter of 240mm.

[0045] The server node is a server node with a height of 48mm (OU) or a server node with a height of 44.45mm (RU).

[0046] The dimensions of the power module housing are 265mm × 73mm × 39mm;

[0047] The number of PSU power supplies is 6;

[0048] The AC power input port is connected to the 220V power socket of the experimental machine. In this preferred embodiment, by determining the specific dimensions of the cabinet shell, power module, and server node, the entire test cabinet system can better adapt to the space and equipment layout of the laboratory, improving space utilization. At the same time, the connection of the AC power input port of the power module to the 220V power socket of the experimental machine ensures compatibility with the laboratory power environment.

[0049] As can be seen from the above technical solutions, the advantages of this utility model are as follows: This solution provides a power supply module for testing rack-mount servers, which can be easily connected to the 220V AC power supply in the laboratory to provide the required DC power to the rack-mount server nodes; furthermore, the test rack for rack-mount servers in this solution eliminates the dependence on power supply interfaces, and also eliminates the rack size limitation by the rack shell height being less than a set height threshold, and solves the liquid cooling test environment limitation by using a blind-plug manifold interface board; this allows rack-mount server nodes to be independently, flexibly, and efficiently debugged and tested on laboratory benches like ordinary servers, eliminating the dependence on dedicated computer room environments and reducing testing costs and difficulties; through optimized cable management via hub settings, the efficiency and accuracy of testing are improved, enabling rapid equipment installation and debugging, facilitating signal measurement and fault diagnosis, and also enabling comprehensive performance testing of power supply, liquid cooling, and other systems to ensure the stable operation of rack-mount server nodes under various operating conditions. Furthermore, the modular and standardized design of the test cabinet and power supply modules supports various specifications of server nodes and power supply modules, and can be easily connected and integrated with external network devices or external air-fluid CDUs, improving the compatibility and scalability of the entire system.

[0072] Example 1

[0073] like Figure 1 As shown, a test power supply module for rack-mount servers includes a module housing.

[0074] The module housing contains a power board 1 and several PSU power supplies 2;

[0075] Each PSU power supply 2 has an AC power input port connected to its input terminal. Each AC power input port is located on the outer shell of the module and is matched with the power socket 3 of the experimental machine.

[0076] The power board 1 is provided with a CRPS connector 4 and a combined power supply line 5. The CRPS connector 4 is connected to the output end of each PSU power supply 2 and the combined power supply line 5. The other end of the combined power supply line 5 is connected to a power supply cable 6.

[0077] The module housing is also provided with a power clip connector 7;

[0078] The power clip connector 7 is connected to the power supply cable 6;

[0079] Specifically, the 54V DC outputs of each PSU power supply 2 are combined by merging the power supply cable 5, and then the power supply cable 6 is connected to the power clip connector 7.

[0080] It should be noted that by setting an AC power input port that matches the power socket of the experimental machine, the problem of the lack of a 380V high-current three-phase AC power interface for laboratory machines in the existing technology is solved. This allows the server nodes in the entire rack to be tested on ordinary laboratory machines without relying on a specific computer room power environment, thus improving the flexibility and convenience of testing. Integrating the power board 1 and several PSU power supplies 2 into the module housing, and setting up components such as CRPS connectors 4, combined power cabling 5, and power clip connectors 7, not only achieves stable power supply and effective distribution, but also makes the power module structure compact, easy to install and maintain, reduces the complexity and failure risk of external wiring, and improves the overall reliability and stability.

[0081] Example 2

[0082] like Figure 2 As shown, unlike Embodiment 1, the power board 1 is also equipped with a BMC 8;

[0083] The BMC 8 is connected to each PSU power supply 2 via I2C bus 11;

[0084] The BMC 8 is connected to a PHY chip 9, which has a GE interface and is connected to an RJ45 management network port 10 through the GE interface.

[0085] The RJ45 management port 10 is located on the module housing;

[0086] It should be noted that the BMC 8 on the power board 1 accesses the PSU power supply 2 through the I2C bus 11 to realize the status management of the PSU power supply 2. The BMC 8 leads out a GE interface through the PHY chip 9 and connects to the RJ45 management network port 10 on the front window of the power module. It can also be connected to the laboratory switch and management host to realize the monitoring and management functions of the PSU power supply 2.

[0087] Example 3

[0088] like Figure 3 As shown, a test rack for rack-mounted servers includes a rack housing 12, the height of which is less than a set height threshold.

[0089] The cabinet housing 12 is provided with a front window 12.1, a rear window 12.2, a top cover 12.3, a bottom, and two side walls;

[0090] The cabinet housing 12 is equipped with a power module 13 and several server nodes 14.

[0092] The rear window 12.2 is equipped with a power supply copper busbar 15;

[0093] The power supply copper busbar 15 is connected to the power clip connector 7 and each server node 14.

[0094] Each AC power input port of the power module 13 is connected to the power socket 3 of the experimental machine through a power supply cable passing through the front window 12.1 of the cabinet housing 12.

[0095] This embodiment uses the test power module for rack-mount servers as described in Embodiment 1 or Embodiment 2. Combined with the power supply copper busbar 15 set in the rear window 12.2, it can effectively provide a stable power supply for the server node 14 in the rack. At the same time, it solves the problems of mismatched laboratory power interfaces and unstable power supply, ensuring the normal operation of the server node in the laboratory environment. Furthermore, since the height of the rack housing 12 is less than the set height threshold, the volume is greatly reduced compared to traditional racks, making it easier to move and place in the laboratory environment. This solves the problem that racks are too large to be placed on laboratory benches, allowing rack-mount server nodes to be independently debugged in the laboratory environment.

[0096] Example 4

[0097] like Figure 4 As shown, a test rack for rack-mounted servers includes a rack housing 12, the height of which is less than a set height threshold.

[0105] Each side wall has a vertical fixed bracket with a horizontal L-shaped bracket, and the horizontal L-shaped brackets of two side walls are arranged in a group facing each other.

[0106] The server node 14 and the power module 13 are mounted on a corresponding set of horizontal L-shaped brackets;

[0116] The blind-plug manifold interface board includes a first blind-plug manifold interface board 18.1 and a second blind-plug manifold interface board 18.2;

[0117] The first blind-plug manifold interface plate 18.1 and the second blind-plug manifold interface plate 18.2 are disposed opposite to each other on both sides of the power supply copper busbar 15 and are fixedly disposed on the reinforcing rib 17;

[0118] The first blind-insertion manifold interface board 18.1 connects the liquid inlet of each server node 14 with the water outlet of the external air-liquid CDU 16.

[0119] The second blind-insertion manifold interface board 18.2 connects the liquid outlet of each server node 14 with the water inlet pipe of the external air-liquid CDU 16;

[0120] The hub includes a first hub 19.1 and a second hub 19.2;

[0121] The first hub 19.1 and the second hub 19.2 are disposed opposite to each other on both sides of the power supply copper busbar 15, and the first hub 19.1 is disposed between the first blind-plug manifold interface plate 18.1 and the power supply copper busbar 15, and the second hub 19.2 is disposed between the second blind-plug manifold interface plate 18.2 and the power supply copper busbar 15.

[0122] The top cover 12.3 of the cabinet housing 12 is removable;

[0123] The RJ45 management port 10 is provided with the front window 12.1 of the cabinet housing 12;

[0124] The spacing between two adjacent groups of horizontal L-shaped supports is 1U in height;

[0125] The cabinet housing 12 is 600mm wide, 1200mm long, and 240mm thick;

[0126] The server node 14 is a server node with a height of 48mm (OU) or a server node with a height of 44.45mm (RU).

[0127] The dimensions of the power module 13's module housing are 265mm × 73mm × 39mm;

[0128] The number of PSU power supplies 2 is 6;

[0129] The AC power input port is connected to the 220V power socket of the experimental machine;

[0130] It should be noted that the test rack supports a height of 5U, with each U being 48mm high. It supports the insertion of 48mm OU high nodes or 44.45mm RU high nodes into the rack housing 12.

The small air-liquid CDU transfers heat from the liquid to the air through its own fan and can be placed on a nearby laboratory workbench. Alternatively, a blind-plug manifold interface board can be installed on the test rack. The server node is first inserted into the blind-plug manifold interface board, and then the blind-plug manifold interface board leads out inlet and outlet water pipes to the small air-liquid CDU. Or, the water pipes can be manually connected directly between the rear window of the server node and the small CDU without using a blind-plug manifold interface board for conversion.

[0133] When using liquid-cooled blind-plug rack nodes, a small blind-plug manifold interface board can be designed for the rear window 12.2 of the test rack. The blind-plug manifold interface board has a height of 5U and is used for blind-plugging server nodes 14 onto the blind-plug manifold interface board of the rear window. When using cable blind-plug rack nodes, a small test-specific hub can be designed with a simple blind-plug cable connection topology (such as loopback mode) for testing the backplane side interface of server nodes 14. When using the small blind-plug manifold interface board and the small hub, a horizontal reinforcing rib structure 17 needs to be designed at the rear of the rack to enhance the structural installation strength of the blind-plug manifold interface board and the hub.
