RAID Controller RS25AB080 is an intelligent, low-profile RAID adapter with
an integrated LSI SAS2208 dual-core RAID-On-Chip chipset, providing both a SAS
controller and RAID engine. With 1GB RAM built onto a memory board which is
connected to the RAID baseboard by default, and eight independent ports supporting
6Gb/s and 3Gb/s SAS data transfers using two SFF-8087 mini multi-lane connectors, this
controller supports up to 48 enterprise-class SAS or SATA devices. The PCI Express*
connector fits into an x8 or x16 PCI Express* slot capable of performance up to 8GT/s
per lane.
The RAID Controller is designed to fit various Intel
