Marketing Information:

The PCI Express (PCIe) Dual – x4 3Gb SAS RAID Adapter supports the attachment of Serial attached SCSI (SAS) disk and SAS solid-state drives using a pair of mini SAS 4x connectors. The 5903 has a 380 MB write cache and a concurrently replaceable cache battery pack. The adapter must always be installed in pairs and is always to be used in a high availability, multi-initiator RAID configuration using two adapters in dual-controller mode. Two 5903 adapters provide mirrored write-cache data and mirrored RAID parity footprints between the adapters. If the 5903 pairing is broken, then write cache is disabled.
