This field is enabled only if power saving on configured drives is supported on the controller.
Power Save (Dimmer Switch feature) is a technology that conserves energy by placing certain unused drives into
a Power Save mode. In Power-Save mode, the drives use less energy. The fan and the enclosure require less
energy to cool and house the drives, respectively. Also, this technology helps avoid application time-outs caused
by spin-up delays and drive wear caused by excessive spin-up/down cycles.
