Wake-on-SAS to Power ON / OFF the System
For use with QSAN XCubeSAN series, QSAN’s Wake-on-SAS technology allows you to
remotely power on/off all cascaded XD5300 expansion enclosures by using QSAN
proprietary SAS cables. Wake-on-SAS ensures that expansion enclosures will not run idly,
consuming electricity after the SAN storage system is shut down for maintenance or other
purposes. Wake-on-SAS can avoid unnecessary electricity waste by allowing your devices to
be on only when it is necessary. A further advantage of Wake-on-SAS is that when you turn
on the SAN, the expansion enclosures will wake automatically, so there is no need to worry
about degrading a volume if you forget to turn them on first.
The table below shows the available expansion cable, model name, and its description.
