MegaRAID SCSI 320-0 Hardware Guide 1-1
Copyright © 2002 by LSI Logic Corporation. All rights reserved.
Chapter 1
Overview
This chapter provides an overview of the MegaRAID®SCSI 320-0 and
basic SCSI features. It contains the following sections:
·Section 1.1, “Features”
·Section 1.2, “NVRAM and Flash ROM”
·Section 1.3, “Single-Ended and Differential SCSI Buses”
·Section 1.4, “Maximum Cable Length for SCSI Standards”
·Section 1.5, “SCSI Bus Widths and Maximum Throughput”
·Section 1.6, “Documentation”
The MegaRAID SCSI 320-0 zero-channel RAID (ZCR) controller is a
high-performance intelligent PCI-to-SCSI host adapter with RAID control
capabilities. The MegaRAID SCSI 320-0 is a low-profile card that
provides reliability, high performance, and fault-tolerant disk subsystem
management.
MegaRAID SCSI 320-0 can be installed in a special PCI expansion slot
in a computer with a motherboard that has the LSI Logic 53C1030 SCSI
chip. The zero-channel adapter converts a motherboard’s own on-board
SCSI controller into a powerful PCI SCSI RAID solution, and is targeted
for 1U and 2U server environments.
The MegaRAID SCSI 320-0 is part of the LSI Logic Intel i960RM/RS-
based MegaRAID controller family, and is an entry-level to mid-range
RAID controller solution. This controller offers a cost-effective way to
implement RAID in a server.
The MegaRAID SCSI 320-0 supports data transfer rates up to 320
Mbytes/s per channel, and it supports up to fifteen non-Ultra SCSI
devices. MegaRAID SCSI 320-0 includes MegaRAID features and
performance.

1-2 Overview

1.1 Features
MegaRAID SCSI 320-0 features include:
·Provides a high performance I/O migration path while preserving
existing PCI-SCSI software.
·Performs SCSI data transfers up to 320 Mbytes/s.
·Performs synchronous operation on a wide low-voltage differential
(LVD) SCSI bus.
·Allows up to 15 LVD SCSI devices on the wide bus.
·Includes an Intel GC80302 integrated I/O processor that performs
RAID calculations and routing.
·Supports 32 to 128 Mbytes of SDRAM on-board cache memory used
for read and write-back caching, and RAID 5 parity generation.
1.2 NVRAM and Flash ROM
A 32 Kbyte x 8 nonvolatile random access memory (NVRAM) stores
RAID system configuration information. The MegaRAID SCSI 320-0
firmware is stored in flash ROM for easy upgrade.
1.3 Single-Ended and Differential SCSI Buses
The SCSI standard defines two electrical buses:
·Single-ended bus
·Low-voltage differential bus
