The Hardware Layer
Using the tests mapped to this layer, you can quickly determine the current status of the hardware on which EVA storage array operates, and thus be proactively alerted to potential hardware failures. The hardware monitored include the I/O communication buses, the fans and the power supply points on the array controller, and the array enclosure and its components such as temperature sensors, power supply units, modules, EMU, and fans.
