• SAS-to-SAS : 2 x 12Gb/s SAS Ports
High Performance ROC
Dual Core RAID-on-Chip (ROC) 1.2 GHz
2GB (default), up to 8GB DDR3-1866 ECC Protection
Up to 512 12Gb/s SAS/SATA drives, using SAS expanders
One downstream SFF-8644 (4 x 12Gb/s) expansion connectors per controller
There are three interfaces in this external storage systes, SAS, Fiber and iSCSI.
The 12Gb/s SAS interface supports both 12Gb/s SAS disk drives for data-intensive applications and 6Gb/s SATA drives for low-cost bulk storage of reference data. The Fibre/SAS/iSCSI to 12Gb/s SAS RAID controllers attach directly to SATA/SAS midplanes with 3/4 x Z-PACK HM-Zd high speed connectors or increase capacity using one additional Min SAS HD SFF-8644 external connector.
The 12Gb/s SAS RAID subsystem supports flexibility interface configuration; 8 x 12Gb/s SAS ports, 2/4 x 16Gb/s fibre channels or 2 x 10Gb/s iSCSI channel host and 4 x 12Gb/s SAS ports expander for performance and easy expansion. When used with 12Gb/s SAS expanders, the controller can provide up to (256) devices through one or more SAS JBODs, making it an ideal solution for enterprise class storage applications that called for maximum configuration flexibility.
