Overview
The Intel
®
RAID Controller RT3WB080 is a high-performance, intelligent PCI Express*
2.0-compliant SATA III RAID controller that offers reliability, high performance, and
fault-tolerant disk subsystem management. This is a RAID solution that meets the internal
storage needs of workgroup, department, or enterprise systems to use cost-effective SATA
or high-performance SAS media.
As a second-generation PCI Express* RAID controller, the Intel
®
RAID Controller
RT3WB080 addresses the growing demand for increased data throughput and scalability
requirements across mid-range and enterprise-class server platforms.
The controller can be connected to up to eight drives directly and allows the use of
expanders to connect to additional drives. For more information about the use of
expanders, see the
ANSI SAS Standard Specification, Version 2.0 .
SATA is serial, point-to-point device interface that uses simplified cabling, smaller
connectors, lower pin counts, and lower power requirements than parallel SCSI.
The optional Intel
®
RAID Smart Battery AXXRSBBU7 provide cached data protection
for the RAID controller, even during system failures.

RAID Controller RT3WB080
The Intel
®
RAID Controller RT3WB080 is an intelligent, low-profile RAID adapter with
an integrated LSI SAS2108 RAID-On-Chip chipset, providing both a SATA controller
and RAID engine. With 256-MB RAM built onto the board and eight independent ports
supporting 6Gb/s and 3Gb/s SATA data transfers using two SFF-8087 mini multi-lane
connectors, this controller supports up to 16 enterprise-class SATA devices and 64 virtual
drives. The PCI Express* connector fits into an x8 or x16 PCI Express* slot capable of
performance up to 5 Gb/s per lane. The RAID controller is designed to fit the following
