Embodiment Construction

[0014] The fan control system based on the SPARC architecture server of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the fan control system based on the SPARC architecture server of the present invention uses the W83795 monitoring chip to collect temperature information in the node, and is connected to the management module in the node through the SMbus bus, and the management module passes the network or SMbus bus to each node. The hardware information is transmitted to the system management unit through the backplane; the system management unit manages the system fan module through the SMbus bus according to the temperature status of each node, controls the fan speed, and adjusts the system ambient temperature.

[0016] The thermistor is placed directly under the main heating element in the printed board; and the bias resistance value of the thermistor is determined through thermal ...

Abstract

The invention provides a fan control system based on an SPARC architecture server. A W83795 monitoring chip is used for acquiring the temperature information in nodes and is connected to a management module in the nodes through an SMbus, and the management module transmits hardware information of each node to a system management unit through a network or the SMbus via a back plate; the system management unit manages a system fan module, controls the speed of the fan and adjusts the system environment temperature through the SMbus according to the temperature state of each node. Compared with the prior art, the system has the advantages that the temperature states of the nodes can be grasped in real time, the system fan can be managed and controlled effectively, and the system is reasonable in design, simple in structure, easy to machine and convenient to use and has high using value.

Description

technical field [0001] The invention relates to the field of fan control systems, in particular to a fan control system based on SPARC architecture servers. Background technique [0002] Nowadays, in the field of computer in our country, independent design has formed a trend. Among them, the processor IC represented by the Phytium processor based on the SPACR architecture has been widely recognized due to its excellent performance and design freedom, and has developed the CPCI- S, ATCA, SSI and other server systems in the form of blades. [0003] The density of blade servers is much higher than that of traditional rack-mounted servers, and the space for components and devices is extremely limited, so that nodes must use passive heat dissipation, and the form of active heat dissipation for the whole machine; in addition, the Phytium processor has high power consumption and general heat resistance. ; Therefore, once the wind speed of the whole machine is too low, the CPU in t...
