AccuSTOR AS424IXR - 4U 24 Bay 6G SAS/SATA to SAS JBOD w/ Dual IO Controller (AR424I(T)R Exp.)


The AccuSTOR AS424IXR is a 4U rack-mountable 6G SAS JBOD rackmount for expansion with AccuRAID AR424IR or AR424ITR, SAS/SATA to iSCSI RAID storage system. Built-in with dual IO SAS controllers, the AS424IXR provide high availability and high redundant expansion storage for iSCSI storage. Utilizing the latest 6G SAS/SATA technology, the AS424IXR provides mini-SAS host to 24 high performance 6G SAS hard drives or high capacity SATA drives (Additional Mux Board required for SATA drives). The AS424IXR includes two mini-SAS ports for expansion with the AR424IR or AR424ITR RAID head unit allowing it to expand up to 2 additional units, which equals to a total of 72 HDD bays (4U-24 AR424IR or AR424ITR plus 2 * 4U-24 AS424IXR supporting a maximum of 216TB with 3TB hard drives). When connect to AR424IR or AR424ITR and AS424IXR, it establish a single multi-terabyte RAID capable volume saving users the cost of purchasing additional RAID units. Redundant power supply, hot-swappable cooling fan and cable-less backplane design allows easy trouble shooting and maintenance. The versatility of the AS424IXR allows easy configuration and integration with the AccuRAID AR424IR or AR424ITR Dual Quad iSCSI RAID Storage array system. With flexible configuration and easy integration with existing AccuRAID AR424IR or AR424ITR makes AS424IXR a high performance and high-redundancy data storage expansion units.
