12Gb/s Intel
®
RAID Controller
Overview
This document is the primary reference and user’s guide for the Intel
®
RAID Controllers
based on the 12Gb/s SAS/SATA RAID-on-a-chip (ROC) devices. This document contains
complete installation instructions and specifications for these RAID controllers.
Overview
The 12Gb/s Intel
®
RAID Controllers are high-performance intelligent PCIe-to-
SATA+SAS controllers with RAID control capability. The 12Gb/s Intel
®
RAID
Controllers provide reliability, high-performance, and fault-tolerant drive subsystem
management. They are an ideal RAID solution for the internal storage of workgroup,
departmental, and enterprise systems.The 12Gb/s Intel
®
RAID Controllers offer a cost-
effective way to implement RAID in a server.
SAS technology brings a wealth of options and flexibility with the use of SAS devices and
SATA devices within the same storage infrastructure. However, SAS devices and SATA
devices bring individual characteristics that make each one a more suitable choice
depending on your storage needs. The 12Gb/s Intel
®
RAID Controller gives you the
flexibility to combine these two similar technologies on the same controller, within the
same enclosure, and in the same virtual drive.
Note: Carefully assess any decision to mix SAS drives and SATA drives within the same virtual
drive. Although you can mix drives, the practice is strongly discouraged.
Intel offers a family of 12Gb/s Intel
®
RAID Controllers that address the needs for both
internal and external solutions. The 12Gb/s Intel
®
RAID Controllers are based on the LSI
first-to-market SAS IC technology and proven MegaRAID technology. As second-
generation PCIe RAID controllers, these controllers address the growing demand for
increased data throughput and scalability requirements across midrange and enterprise-
class server platforms. These controllers provide these features:
•
12 Gb/s Serial Attached SCSI (SAS) performance
•
6 Gb/s SATA III performance
•
Eight-lane, 8 GT/s PCIe host interface
