Description
Areca Arc-9224SS-DR2
2U 24 Bay 2.5 inch SAS-to-SAS RAID Subsystem
Host Interface
• 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
Drive Interface
Up to 512 12Gb/s SAS/SATA drives, using SAS expanders
One downstream SFF-8644 (4 x 12Gb/s) expansion connectors per controller
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 SAS 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.
Other options:The 12Gb/s SAS RAID subsystem supports flexible 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 port expanders 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 calls for maximum configuration flexibility.
