Description

A complete cabinet server and its multiplexed power supply module

technical field

The invention relates to the technical field of servers, in particular to a multiplexed power supply module. The invention also relates to a complete cabinet server.

Background technique

The demand for servers in the Internet industry is increasing day by day, and more and more customers will consider building their own cabinet servers. The whole cabinet server integrates multiple single-node servers, switches, cooling and power systems, and optimizes and upgrades the use and management of traditional multiple single-node servers.

Compared with single-node servers, the whole cabinet server has the following advantages: 1. The whole cabinet server can improve the space utilization rate of the server room. Due to the power supply system of multiple nodes in the whole cabinet, the cooling system realizes unified management, which saves a lot of computer room space. Second, the whole cabinet server improves the power efficiency. The centralized management module of the entire cabinet can centrally adjust the load rate of the power module to cope with different computing scenarios. 3. The whole cabinet server can reduce power consumption. Because the centralized management module of the whole cabinet can centrally adjust the power consumption of the cooling system to cope with different working scenarios. Fourth, the whole cabinet server improves the simplicity and convenience of delivery. Since most of the whole cabinet assembly can be realized in the factory, the workload of reassembly in the server room is greatly reduced, and the delivery of the whole cabinet becomes more concise.

At present, many Internet companies have the requirements for using both single-node servers and full-rack servers, but the power supply module of a single-node server is quite different from that of a full-rack server. The same server motherboard needs to support both single-node power supply and the power supply of the whole cabinet, which requires two different power supply modules to be designed for the single-node server and the whole cabinet server to meet the power supply of the same motherboard in different server chassis. .

The power supply of a single-node server generally uses a CRPS power supply. The input of the CRPS power supply module is 220V AC power, and the output is a gold finger. The gold finger is connected to the CRPS power connector on the motherboard to output the 12V DC power supply and CRPS logic signals to the motherboard. The power supply input of the whole cabinet server is taken from the power supply copper bar at the rear of the whole cabinet, generally 48V DC power supply or 12V DC power supply. Riveted to the connector and connected to the power board. Then, the power board is connected to the main board of the sub-node server at each layer for power supply through connectors or cables.

However, due to the different structural models of the power supply unit of the single-node server and the power supply unit of the whole cabinet server, when building the whole cabinet server, the sub-node servers of each layer of the whole cabinet server cannot share the same specification as the single-node server. motherboard, or two sets of motherboards with different specifications must be used, which will inevitably lead to an increase in the construction cost. At the same time, the output logic signal of the power supply unit of the whole cabinet server does not match the output logic signal of the power supply unit of the single-node server, so that the sub-node servers of each layer of the whole cabinet server cannot share the same set of mainboard management software with the single-node server.

Therefore, how to solve the problem that the single-node server and the entire cabinet server cannot share the motherboard and the motherboard management software due to the different structure of the power supply unit, and reduce the construction cost, is a technical problem faced by those skilled in the art.

The golden finger 3 is arranged at the other end of the support frame 1 , and is mainly used to form a signal connection with the CRPS power connector reserved on the motherboard to form a signal connection, so as to transmit power to the motherboard.

The power supply control board 4 is arranged on the support frame 1, and is connected with the power supply clip 2 and the gold finger 3 at the same time. The control signals output to the main board are the same, so that the main board in each layer of sub-node servers in the built-in cabinet server maintains the same power supply mode as the single-node server, so that the entire cabinet server can share the main board with the single-node server. and motherboard management software.

Compared with the prior art, the multiplexed power supply module provided in this embodiment does not require additional modification or replacement of the main board power receiving structure and main board management software, so the construction cost of the entire cabinet server can be greatly reduced, which is convenient for the server room. Use both single-node servers and full-rack servers.

In a preferred embodiment of the support frame 1, in order to facilitate the installation of the reusable power module in the cabinet, in this embodiment, the support frame 1 is a rectangular frame, and in order to avoid extra space, it is convenient for the server chassis For common use on a single-node server and a complete cabinet server, the external dimension of the support frame 1 is the same as that of the CRPS power supply in the prior art (there are many standard specifications). In this way, when the multiplexed power supply module is installed on the server in the whole cabinet, the installation method will be the same as the installation method of the CRPS power supply on the single-node server. Of course, if necessary, the volume of the support frame 1 can also be appropriately reduced or its shape can be modified on the basis that the size structure of the margin finger 3 is kept compatible with the CRPS power supply.

Further, in order to optimize the distribution form of each component on the support frame 1, in this embodiment, the power supply clip 2 is specifically arranged on the front end face (or rear end face) of the support frame 1, and correspondingly, the gold finger 3 is specifically arranged. On the rear end face (or front end face) of the support frame 1, the two are arranged at both ends of the length direction of the support frame 1, so as to use the power supply clip 2 to connect with the power supply row on the cabinet and the gold finger 3 to connect with Connect to the CRPS connectors on the mainboard of the sub-node server at each layer.

Not only that, in order to facilitate the power supply clip 2 to transfer the power to the gold finger 3 for output after taking the power, a power supply cable 5 is added to the support frame 1 in this embodiment. Specifically, one end of the power supply cable 5 is connected to the end of the power supply clip 2 , and the other end is connected to the power supply control board 4 , and then connected to the gold finger 3 through the power supply control board 4 .
