4. Integrated Intel® RAID Controller SROMBU42E
The Intel® Server Board SE7520AF2 supports Raid-On-MotherBoard (ROMB) through the
Intel® 80332 I/O processor (IOP332) with Intel® XScale Technology, the LSI Logic* 53C1030
SCSI controller, resident RAID firmware on the server board and RAID operating system
drivers. This chapter provides a general overview of the integrated Intel® RAID Controller
SROMBU42E functionality of the Intel® Server Board SE7520AF2.
4.1

Overview

The Intel® RAID Controller SROMBU42E is a high-performance intelligent solution with
Redundant Array of Independent Disks (RAID) control capabilities. The controller 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
controller offers a cost-effective way to implement RAID on the Intel® Server Board
SE7520AF2.
The Intel® RAID Controller SROMBU42E solution (dual-channel) uses the Intel® 80332 I/O
processor with Intel® XScale Technology, resident RAID firmware and the onboard LSI Logic*
53C1030 U320 SCSI controller to offer two SCSI RAID channels via the two onboard VHDCI
68-pin SCSI connectors. The integrated controller supports a low voltage differential (LVD)
SCSI bus with throughput on each SCSI channel up to 320 Mbytes/s.
The Intel® RAID Controller SROMBU42E functionality can be enabled on the Intel® Server
Board SE7520AF2 by using the optional Intel® RAID Activation Key (1-wire serial security
EEPROM), using dedicated RAID memory installed on Slot 2 (RAID DIMM) and by enabling the
IOP ROMB setup option in BIOS Setup.
Note: The IOP ROMB option in BIOS Setup is grayed out unless a valid Intel® Activation Raid
Key and compatible RAID memory are present.
