Intel RAID Controller RS2WC080
The Intel
RAID controller based on the LSI*SAS2008 PCI* Express-SAS/SATA I/O Processor
chip, providing both a SAS controller and RAID engine. With 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 64 physical drives including up to 16 enterprise-
class SAS or SATA devices in up to 16 RAID arrays. Drives not configured as part of a
RAID array can be configured as "pass through" drives in Non-RAID mode. The PCI
Express* connector fits into an x8 or x16 PCI Express* slot capable of performance up to
5 Gb/s per lane.
The SAS RAID controllers support the SAS protocol as described in the Serial Attached
SCSI Standard, Version 2.0. The controllers also support the Serial ATA II (SATA II)
protocol defined by the Serial ATA Specification, Version 1.0a and the Serial ATA II:
Extension to the Serial ATA Specification, Version 1.1. SATA II is an extension to SATA
1.0a.
In addition, the SAS RAID controllers support the following SATA II features:
•
3Gb/s SATA II
•
Staggered spin-up
•
Hot plug
•
Native command queuing
•
Activity and fault indicators for each PHY
•
Port selector (for dual-port drives)

Protocol Support

Each port on the SAS controllers supports SAS devices, SATA II devices, or both using
SSP, SMP, STP, and SATA II as follows:
•
Serial SCSI Protocol (SSP) to enable communication with other SAS devices.
•
SATA II Protocol to enable communication with other SATA II devices.
•
Serial Management Protocol (SMP) to share topology management information
with expanders.
•
Serial Tunneling Protocol (STP) support for SATA II through expander interfaces.

Operating System Support

•
Microsoft Windows Server 2003*, Microsoft Windows Server 2008*, and Windows
Vista*.
•
Red Hat* Enterprise Linux 4.0, and 5.0.
•
SuSE* Linux Enterprise Server 10 and 11.
