1.1

Overview

The Intel

®

RAID Controller SRCU42E is a high-performance intelligent PCI Express* host

adapter with Redundant Array of Independent Disks (RAID) control capabilities. The RAID

Controller SRCU42E provides reliability, high performance, and fault-tolerant disk subsystem

management. It is an ideal RAID solution for the internal storage of workgroup,

departmental, and enterprise systems. The RAID controller offers a cost-effective way to

implement RAID in a server.

The RAID Controller SRCU42E (dual-channel) is a PCI Express* controller that has one

LSI* 53C1030 controller chip that controls two SCSI channels. The RAID controller has two

VHDCI 68-pin external SCSI connectors and two HDCI 68-pin internal SCSI connectors.

The RAID Controller SRCU42E supports a low voltage differential (LVD) or a single-ended

(SE) SCSI bus. With LVD, you can use cables up to 12 meters long. Throughput on each

SCSI channel can be as high as 320 Mbytes/s.

You can install the Intel

®

RAID Controller SRCU42E in PCI-Express computer systems with

a standard bracket type. With this RAID controller in your PCI-Express system, you can

connect SCSI devices over a SCSI bus.

For Ultra320 SCSI performance, you must connect only LVD devices to the bus. Do not mix

SE with LVD devices, or the bus speed will be limited to the slower SE (Ultra SCSI) SCSI

data transfer rates. Do not connect a high voltage differential (HVD) device.

The Intel

®

RAID Controller SRCU42E supports major operating systems, such as Microsoft*

Windows* XP, Microsoft* Windows* 2000, Microsoft* Windows Server* 2003, Novell*

NetWare*, Red Hat* Linux*, and SuSE* Linux*.

Note:

The operating systems supported by this controller may not be supported by

your server board. Please refer to the tested OS list for your server board at

http://support.intel.com/support/motherboards/server/

. See also the tested

hardware and operating system list for the RAID Controller SRCU42E to make

sure the RAID controller supports your operating system.
