Description
Technical field
The present invention relates to computer fields, and more specifically, more particularly to a kind of fan monitoring device.
Background technique
The integrated level of server is higher and higher at present, especially as blade server and be exclusively used in artificial intelligence calculating AI
Server etc. is integrated with more CPU, GPU, memory bar and hard disk etc., the server of high integration in lesser chassis space
The pressure of case radiation is also exacerbated while higher performance is provided.The common radiating mode of server is still to pass through at present
To take away the heat in cabinet, the heat-sinking capability of fan largely affects Wind-cooling type service for fan exhausting or blowing
The performance of device work.Due to being constantly in the state of running at high speed, long-time abrasion and dust accretions in server booting rear fan
Fan axis lubricity can be made poor, fan noise increases and revolving speed lowers, it is also possible to machine core is burnt out when serious, influences machine
The normal operation of device.And the bonder terminal plug number of fan is also limited (usual tens times), each fan and master
The hot-swappable of plate can all cause bonder terminal to damage, so that signal transmission quality be made to decline.Shape is run to fan in server
The monitoring of state is necessary.
Fan largely affects service as heat dissipation equipment important in Wind-cooling type server, operating status
The working performance of device entirety.But fan is just continued for operating from after booting, long-term abrasion and dust accretions are easy to
Fan failure is caused, and the connector plug number between hot-swappable fan and mainboard is supported also to be limited, frequently
Plug fan can cause bonder terminal to damage firmly, influence its signal transmission performance.Fan and its connector are in the description
It both provides its mean time between failures in service life-and limits the number of plug, the rear fan more than above-mentioned specified value holds very much
It easily breaks down, needs to replace fan in time.But does not have in the design of server system at present and fan is continued working
The hot-swappable number of accumulation duration and fan is monitored, and is all that fan is just replaced after the entirely ineffective alarm of fan, fan is more
The delay changed easily causes server system delay machine.
Aiming at the problem that lacking fan fails monitoring and early warning in the prior art, there has been no effective solution schemes at present.
