(16Gb/s Fibre-to-SAS Redundant 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 Fibre 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. 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.

The Fibre to 12Gb/s SAS RAID subsystem provides three kinds of host interface link to the host board on the server system. This subsystem utilizes the same RAID kernel that has been field-proven in existing internal/external SATA/SAS RAID controller products, allowing to bring stable and reliable SAS RAID external subsystem.
