8.5 Changing Power Settings
The RAID controller includes Dimmer Switch™ technology that conserves energy by
placing certain unused drives into Power-Save mode. In Power-Save mode, the drives
use less energy, and the fan and the enclosure require less energy to cool and house
the drives, respectively. Also, this technology helps avoid application timeouts caused
by spin-up delays and drive wear caused by excessive spin-up/down cycles.
You can use the Power Settings field in MSM to choose whether to allow unconfigured
drives or hot spares to enter Power-Save mode.
NOTE: The Dimmer Switch technology is enabled by default.
