8-bay RAID 6 towers ship
Sans Digital has launched a new series of 8-bay MobileRAID towers, featuring dual channel SCSI, SAS and Fiber Channel connections and hardware RAID 6. RAID 6 balances between parity and speed, while allowing for up to two drive failures at one time without data loss. The MobileRAID towers utilize the engine structure of Sans Digital's AccuRAID rackmount systems, allowing for dual channel support, online expansion, online RAID migration, and RAID roaming. The three towers, the MR8S, MR8X and MR8F4, feature embedded Ethernet web management, allowing for local and remote access of the system status and alerts for system events.
The MobileRAID series utilizes dual channel host interfaces, as well as SPC-3 Persistent Reservation commands. The dual channel host interfaces provides two physical connections for server clustering, allowing automatic failover without data access downtime in a server failure. The SPC-3 Persistent Reservation is a mandatory requirement when clustering via Windows Server 2008. Integrating this feature into the 8-bay MobileRAID models allows them to be fully functional under Mac, Windows and Linux operating systems.
The MR8S, running an UltraSCSI connection, is $3050 with no included drives, the MR8X, running an SAS connection, is $3,625 without drives and the Fiber Channel based MR8F4 is $4,175, also driveless.
