Nexsan AutoMAID™

Energy-Saving Technology

Nexsan AutoMAID is the first MAID 2.0 architecture that supports VTL, full file format D2D and standard high performance RAID, delivering green storage technology through the IT infrastructure.

AutoMAID Level	Energy Savings	Initial I/O Request Resonse Time	Details
Level 1	15 - 20%	Sub-second	Disk heads unloaded
Level 2	35 - 45%	~15 seconds	Disk heads unloaded, disks slowed to run at 4000RPM
Level 3	60 - 70%	30-45 seconds	Sleep mode, but powered-on

Nexsan’s patented MAID (Massive Array of Idle Disks) technology, AutoMAID, is designed to provide real cost savings by reducing the energy requirements & thermal output of unused drives. This feature comes standard on all of Nexsan’s SATABoy disk arrays, and provides transparent cost savings without requiring any software changes. AutoMAID allows IT to choose what combination of cost savings and performance requirements fits their business needs, with three levels of “idleness”:

Level 1: at this level, disks can achieve 15% - 20% savings by unloading the head. The disks keep spinning though, providing sub-second recovery times.

Level 2: achieve 35% - 45% savings by unloading the heads and slowing the disk down to 4000 RPM. At this level, recovery times average 15 seconds.

Level 3: maximize your savings by stopping the disk spin and putting it into sleep mode, but powered on. This level provides 60% - 75% savings, and 30-45 second recovery times.

Data is continuously verified with Nexsan’s AutoMAID technology, which performs periodic surface scans to ensure data integrity.
