AccuRAID AR316IR
The AccuRAID AR316IR is a 3U 16-bay active-active redundant controllers iSCSI to SAS/SATA RAID subsystem. With active-active redundant controllers, along with the redundant powers and cooling fans, AccrRAID AR316IR provides a peace of mind by providing high availability and performance. With built-in 8x 1Gb Ethernet ports supporting independent access, fail-over or load-balancing (802.3ad port trunking, LACP), AR316IR is capable of composing a high performance SAN environment with a fraction of the cost of Fibre Channel RAID storage systems. Supporting RAID 0, 1, 1+0, 3, 5, 6, 30, 50, 60 and JBOD, with global or dedicated hot spare disks, multiple hard drive failure could be protected without downtime or data loss. The built-in powerful 64-bit RAID processor provides high performance through-put.

The built-in Snapshot feature provides point-in-time copy of saved data without relying on the host software. Management is available via Web and Secure Web (HTTPS), SSH telnet or serial console, with built-in event notification via e-mail or SNMP trap. Redundant power supplies, cooling fans and controllers are part of the modularized design to allow redundancy as well as off-self spare parts to eliminate downtime. To increase the return of investment, AR316IR supports both SAS and SATA drives, and could be expanded by adding up to 3 additional SAS/SATA JBOD units, providing solutions up to 64-bays or 196TB in total storage capacity. Intended to provide storage solution for IT and vitalization server computing with VMware vSphere or, Microsoft Hyper-V or Citrix with SCSI-3 persistent target support, the AR316IR is a perfect solution for Storage Area Network needs in IT and other applications.

Note: Sans Digital recommends the use of enterprise hard drives when in use with any RAID controller applications. Standard desktop or green desktop drive may not be supported and may compromise RAID system stability and performance.
