Problems solved by technology

One method is to add a BMC to the storage node to achieve control, but it will increase a lot of cost; the other method is to hand over the heat dissipation control of the storage node to the BMC of the computing node, and pull the management signals such as PWM of the BMC to the storage node. Node mode or BMC-I2C-storage node CPLD mode, but this method requires additional management cables, and it is difficult to achieve real-time cooling control when the BMC hangs up
[0004] There is currently no effective solution to the problems of high cost of cross-node heat dissipation control, many cables, low stability, and poor autonomy in the existing technology

Abstract

The invention discloses a cross-node in-band heat dissipation control method and device. The method includes: sending a first instruction for acquiring temperature information of a storage node by a baseboard management controller of a computing node; The serial connection SCSI expander chip sent to the storage node through the serial connection SCSI data link; the temperature information of the storage node is obtained by the serial connection SCSI expander chip and fed back to the baseboard management controller; the baseboard management controller According to the temperature information of the storage node, it is determined that the second instruction for controlling the working intensity of the fan of the storage node is transmitted to the serial connection SCSI expander chip; the second instruction is sent to the fan of the storage node complex by the serial connection SCSI expander chip Logic programmable device to control the working intensity of the fan. The invention can reduce extra cost, avoid using extra cables, improve work stability and self-control ability of storage nodes.

Description

technical field [0001] The present invention relates to the field of heat dissipation control, and more specifically, to a cross-node in-band heat dissipation control method and device. Background technique [0002] In the development of server cabinets, the combination of computing nodes and storage nodes is becoming more and more popular, and the corresponding heat dissipation management and control methods are gradually attracting attention. At present, servers usually use air cooling to dissipate heat, and a management chip implements a fan control strategy to meet heat dissipation requirements. [0003] In the architecture where computing nodes are paired with storage nodes, computing nodes usually use BMC to control fans, while heat dissipation of storage nodes becomes a problem. One method is to add a BMC to the storage node to achieve control, but it will increase a lot of cost; the other method is to hand over the heat dissipation control of the storage node to the...
