Sans Digital AccuRAID AR424ITR - 4U 24 Bay 4x10GbE iSCSI to SAS/SATA RAID 6 Redundant Controller Storage














The AccuRAID AR424ITR is a 4U 24-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 AR424ITR provides a peace of mind by providing high availability and performance. With built-in 4x 10GbE Ethernet ports supporting independent access, fail-over or load-balancing (802.3ad port trunking, LACP), AR424ITR 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, AR424ITR supports both SAS and SATA drives, and could be expanded by adding up to 3 additional SAS/SATA JBOD units (Total storage: 96 bay or 288TB). 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 AR424ITR is a perfect solution for Storage Area Network needs in IT and other applications
