1. Introduction
This document provides a detailed description of the Intel
®
RAID Controller RS2BL080 and
RS2MB044 and the software that supports them.
Multiple versions of the Intel
®
RAID Controller RS2BL080 are available. This document applies
to following product codes for Intel
®
RAID controller RS2BL080:
 RS2BL080
 RS2BL080DE
Where a feature varies from one product to the next, the difference will be noted in this
document. Unless specified, features apply to all versions of the Intel
®
RAID Controller
RS2BL080.
1.1 Product Overview
The Intel
®
RAID Controller RS2BL080 and RS2MB044 are intelligent PCI Express* 2.0-
compliant SAS/SATA II RAID controller that offers reliability, good 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 RS2BL080 and RS2MB044 address the growing demand for increased data
throughput and scalability requirements across entry-level, mid-range, and enterprise-class
server platforms.
The Intel
®
RAID Controller RS2BL080 contains eight internal SAS/SATA ports. The Intel
®
RAID
Controller RS2MB044 contains four internal and four external SAS/SATA ports. For more
information about the use of expanders, see the ANSI SAS Standard Specification, Version 2.0.
As one version of RS2BL080, the Intel
®
RAID Controller RS2BL080DE version provides
additional data protection feature in the event of theft or loss of physical drives. This version of
the controllers supports the use of self encrypting drives with encryption key management,
provided by the RAID controller firmware.
Note: SATA II is the only type of SATA supported by these RAID controllers.
SATA and SAS are serial, point-to-point device interfaces that use simplified cabling, smaller
connectors, lower pin counts, and lower power requirements than parallel SCSI.
