QSAN’s Wake-on-SAS technology allows you to remotely power on/off all cascaded XD5300 expansion enclosures by using QSAN proprietary SAS cables. You can power on the XCubeSAN system remotely using the Wake-on-LAN feature. The XCubeSAN system can work with any available Wake-on-LAN freeware and shareware. Wake-on-SAS ensures that expansion enclosures will not run idle, consuming electricity after the SAN storage system is shut down for maintenance or other purposes. Wake-on-SAS helps 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 following diagram shows that after the XCubeSAN storage receives the magic packet being sent from the client’s computer, it powers on automatically and uses Wake-on-SAS functionality to power-on the attached XD5300 expansion enclosures.
