Nexsan SASBoy

4.2TB of cost-effective SAS in 3U

Leverage serial-attached SCSI disk technology with Nexsan’s SASBoy RAID enclosures. Great for applications that require high transaction performance, the SASBoy supports 50,000 IOPS from cache and 2,500 IOPS from disk, and can sustain data rates up to 875 Mbps.

Choose between having a single controller, or dual controllers with active-active failover and cache coherency, with the Nexsan SASBoy array of SAS disks. Each controller includes dual 4Gbps FC host interface ports & dual 1Gbps iSCSI ports.

The SASBoy supports 14 x 3.0Gbps serial-attached SCSI 15,000 RPM drives with 300GB of capacity for a total of 4.2TB of high-performance capacity in a slim 3U form factor. 512MB of cache comes standard, with the option for 1GB or 2GB of cache, and includes battery backup of the cache.

The Nexsan SASBoy RAID array is highly available & reliable, 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
• global spare, dynamic spare pooling and dedicated spares
• support for APPA, 4PAA, APAL and DCNR failover modes

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 255 LUNs per controller, 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 spining 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 verfied with Nexsan’s AutoMAID technology, which performs periodic surface scans to ensure data integrity.
