Hitachi Fan Modules Test

The cooling of the Hitachi Compute Blade is governed by six efficient, variable-speed, redundant fan modules. Each fan module includes three fans to tolerate fan failures within a module; an entire module can fail while the other fan modules continue to support the cooling requirements of the chassis. If the fan modules fail frequently, then the cooling of the hardware components of the Hitachi Compute Blade may fluctuate leading to abnormal rise in temperature. This may sometimes cause a permanent damage of the Hitachi Compute Blade. To avoid such critical damage, administrators should constantly monitor the health of the fan modules. The Hitachi Fan Modules test comes in handy to those administrators who would like to monitor the fan modules round the clock!

This test reports the current health of each fan module in the chassis, thus turning the spotlight on those modules that have failed. In addition, the test also checks the status of the power supply to each fan module and also alerts administrators to the redundancy status of each fan module.

Target of the test : Hitachi Compute Blade

Agent deploying the test : An external agent

Outputs of the test : One set of results for each fan module in the Hitachi Compute Blade being monitored.
