The AccuSTOR AS212X6 is a 2U 12 bay rack-mountable 6G SAS JBOD rackmount for high capacity storage. Supporting latest SAS 6G technology, AS212X6 provide 6G solution for 6G SAS or 6G SATA drives. With 6G RAID controller, AS212X6 provide over 1GB/s performance in various RAID format. Dual mini-SAS input allow dual host bus adapter redundancy applications. Due to the wide selection of SAS RAID controllers and diverse controller interfaces, most JBOD units are unable to support detailed enclosure monitoring. This limitation delays the process of troubleshooting, where administrators are unable to promptly identify the problem at first glance. The AccuSTOR AS212X6 addresses this issue by incorporating a user selectable switch, allowing the unit to support monitoring via various brands of RAID controllers. Once the controller model has been determined via the selectable switch, the AS212X6 utilizes industry-standard SCSI Enclosure Services (SES) technology, to allow the communication between the rackmount and the host RAID adapter, without the need for additional monitoring software or hardware cable. Compatible RAID cards include: LSI MegaRAID and Areca SAS RAID controllers.
