Description

A server system and installation method for optimizing heat dissipation

technical field

The invention relates to a heat dissipation optimization system for a server, in particular to a server system and an installation method for optimizing heat dissipation.

Background technique

With the continuous rise and development of Internet and cloud computing technology, higher requirements are put forward for the data processing capability and storage capacity of the server. The general large-scale data center computer room costs a lot of money. Whether it is a computer room rented or a self-built computer room, the rent and construction cost are very expensive.

In order to save floor space and make full use of space, high-density deployed server products came into being. Such products generally have three characteristics: centralized power supply, centralized heat dissipation, and centralized management. The usual server structure is mainly based on 2U chassis, which is deployed on the rack in the computer room. In order to increase the number of servers deployed in the 2U space on the rack in the computer room, the four-star server came into being. Namely: Deploying 4 server nodes in a 2U space can effectively improve the space utilization of the computer room.

For example, a four-star server includes: 4 server nodes, a system cooling fan, a hard disk module, 2 power modules, and 5 parts of the system board. Among them: the power supply of server nodes, system cooling fans, and hard disk modules are all realized by centralized power supply on the system board.

In the traditional four-star server system structure, the server nodes get power directly from the system mid-board, and the fans and hard disk backplanes installed in the system get power from the system mid-board through power supply cables. As the performance of the new generation of CPU is getting better and better, the corresponding power consumption is also getting bigger and bigger. The current flowing on the system board is also increasing, so the system board needs to be provided with larger ventilation holes to solve the heat dissipation problem of the new generation CPU. However, opening larger ventilation holes on the system board will reduce the current carrying capacity of the system board. When the system continues to work at full load, the temperature of the system board PCB will continue to rise, causing the risk of burning the board.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.

Among them, the technical terms involved in the manual have the following meanings:

HDD BP, English full name Hard disk backplane, Chinese meaning is hard disk backplane; PDB, English full name Power Distribute board, Chinese meaning is power distribution board; NODE means server node, PSU means power module, PDB means power distribution board, FAN means fan , HDD means a hard disk module.

As shown in Fig. 1-Fig. 3, the four sub-star server system in the prior art is compared with the present invention as an example for illustration.

As shown in Figure 1, the four-star server system structure used in the prior art includes 4 server nodes 4, 1 system mid-board 1, 4 fans 3, 24-port hard disk backplane 2, and 4 hard disk modules 5. Two power supply modules. Two power supply modules PSU0 and PSU1 are plugged into the system mid-board to supply power for 4 server nodes. Fans FAN0\FAN1\FAN2\FAN3 are located between the system mid-board and HDD BP, and are connected to the system mid-board through cables. Electricity, 4 hard disk modules HDD0-5\HDD6-11\HDD12-17\HDD18-23 are plugged into the 24-port HDD BP, and the HDD BP is connected to the system board through cables to realize the connection of power supply and signal link .

As shown in FIG. 2 , a schematic structural diagram of a board in a system in the prior art. The board is a passive board and does not contain active components such as chips, MOS, and triodes. It is used to realize the interconnection and transfer of power supply and signal of all functional units of the server system. The system board is provided with 4 server node interfaces 8, 2 PSU interfaces 9, 4 air duct openings 7, 4 fan interfaces 6, and 4 HDDBP power supply interfaces 10.

Therefore, in the heat dissipation process of the entire server, the fan draws air from right to left during operation. The cold air in the air duct flows through the four hard disk modules and the hard disk backplane, and then is sucked by the fan through the air duct openings on the system middle board. Then the CPU, memory, PCH, BMC and other components in the server node are cooled, and finally the hot air is discharged from the left side. Because the existing scheme adopts the scheme of the middle board of the system, as the performance of the CPU on the server node continues to improve, the power consumption of the CPU continues to increase. Under the condition that the rated speed of the system fan cannot be increased, it is necessary to reduce the flow resistance of the air duct to take away more heat. In this way, it is necessary to enlarge the opening of the air duct on the middle board of the system, as shown in FIG. 2 . If the opening of the air duct becomes larger, the current-carrying path for supplying current to the server node will inevitably be narrowed, and the current-carrying capacity of the board in the system will decrease, which will cause the problem of local PCB overheating.

As shown in Figure 3, a server system for optimizing heat dissipation in this embodiment includes a server node 4, a power module, a power distribution board 12, and a hard disk backplane 2, and a fan 3 is arranged between the server node 4 and the hard disk backplane 2 , the power supply module supplies power to the hard disk backplane 2 after being connected to the power distribution board 12 through a cable, and the hard disk module 5 is installed on the other side of the hard disk backplane 2, and the hard disk module 5 is connected to the hard disk backplane 2 through a cable; The server node 4 is connected to the hard disk backplane 2 through the node side plate 11; the fan 3 is connected to the hard disk backplane 2 through a cable, and the optimized heat dissipation channel formed by the fan 3 during operation includes cooling air from the hard disk module 5, the hard disk The backplane 2 is sucked by the fan 3 and then discharged after passing through the server nodes 4 . In this embodiment, the power module PSU0\PSU1 is connected to the PDB, and then the PDB is connected to the HDD BP through a cable, and the power supply to each functional unit of the system is realized through the HDD BP. In this system, HDD BP not only includes the function of interconnecting with the hard disk module, but also includes the power supply interconnection and signal interconnection of server node NODE0\1\2\3 and fan FAN0\1\2\3.

The server node and the HDD BP implement power acquisition and signal interconnection to the HDD BP through the node side board. Specifically: the server node NODE0 and the node side board 0 are plugged into the HDD BP for power and signal interconnection. The server node NODE1 and the node side board 1 are plugged into the HDD BP for power and signal interconnection. The server node NODE2 and the node side board 2 are plugged into the HDD BP for power and signal interconnection. The server node NODE3 and the node side board 3 are plugged into the HDD BP for power and signal interconnection.

This system optimizes the working process of the air duct after heat dissipation. When the server is working, the fan draws air from right to left. The cold air in the air duct flows through the hard disk module, and then the system fan directly draws the air flow to the CPU, memory, and PCH, BMC, etc. are cooled, and finally the hot air is discharged from the left side. Therefore, the optimized heat dissipation server system of the present invention can well solve the heat dissipation problem caused by the board in the system, and furthermore, there will be no problem of deterioration of the current carrying capacity.

As shown in Figure 3, a server system installation method for optimizing heat dissipation of the present invention includes the following steps, specifically as follows:

①. Prepare the server node tray, main board, CPU, memory, hard disk, HDD BP, power supply and signal cables, node side board, PDB, power module;
