Nexsan SATABoy

14TB of cost-effective SATA in 3U

The Nexsan SATABoy offers exceptional performance in a slim form factor for nearline and secondary storage, and can even be appropriate as primary storage for some business applications.

The SATABoy supports SATA II 7,200 RPM drives which are available in 1TB, 750GB and 500GB sizes. This serial ATA array features up to 2GB cache with battery backup, and dual RAID controllers with active-active failover that can sustain 370Mbps throughput/controller and high performance cache mirroring. Each controller features dual 2Gbps Fibre ports and dual iSCSI ports for maximum flexibility.

The Nexsan SATABoy RAID disk array is highly available as well, with dual power supplies and quad-redundant cooling fan blowers. All SATA disks and other key components in the SATABoy data storage system are hot-swappable and field-replaceable. Other reliability, availability and serviceability features include:

• real-time monitoring of events, hardware status, and thermal conditions
• a “call-home” feature for pre-emptive monitoring and reporting and active user notification
• systems settings written to flash memory to protect against power loss
• parity scrubbing and array verification scheduling
• SNMP traps

This SATA disk system provides managers with adjustable stripe widths, and supports RAID levels 0, 1, 1+0, 4, 5 and RAID6, including advanced functionality like dynamic spare pooling, array verification, dedicated spares. Multiple RAID sets can be put on a single unit, and the SATABoy supports up to 32 LUNs and LUN masking.

AutoMAID™ Green Storage Technology

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.
