Preface 1

Preface

This document e

xplains how to use the MegaRAID Storage Manager™

software, WebBIOS, and Command Line Interface (CLI) utilities to

configure, monitor, and maintain MegaRAID

®

Serial-attached SCSI

(SAS)

RAID controllers and the storage-related devices connected to

them.

Audience

This document assumes that you

are familiar with SAS controllers and

configuration utilities. The people who benefit from this book are network

administrators who need to create storage configurations on 7KLQN6HU

YHUSAS controllers.

Organization

This do

cument has the following chapters and appendixes:

•

Chapter 1, “Overv

iew,” describes the SAS, Serial ATA (SATA) II, and

Solid State Disk (SSD) technologies, configuration scenarios, and

Technical Support information.

•

Chapter 2,

“Introduction to RAID,” describes RAID (Redundant Array

of Independent Disks), RAID functions and benefits, RAID

components, RAID levels, and configuration strategies. In addition, it

defines the RAID availability concept, and offers tips for configuration

planning.

•

Chapter 3, “Full Disk Encry

ption,” describes the Full Disk Encryption

(FDE) features, terminology, and workflow.

•

Chapter 4, “WebBIOS Configuration Utility

,” explains how to use the

pre-boot WebBIOS Configuration Utility to create and manage

storage configurations.

Preface 2

•

Chapter 5, “M

egaRAID Command Tool,” explains how to use the

MegaRAID Command Tool to create and manage storage

configurations. The MegaRAID Command Tool is a CLI application

for SAS.

•

Chapter 6, “Me

gaRAID Storage Manager Overview and Installation,”

introduces the main features of MegaRAID Storage Manager

software and explains how to install it.

•

Chapter 7, “M

egaRAID Storage Manager Window and Menus,”

describes the layout of the MegaRAID Storage Manager window and

lists the available menu options.

•

Chapter 8, “Con

figuration,” describes how to use the MegaRAID

Storage Manager software to configure or reconfigure storage

devices, how to save configurations, and how to apply saved

configurations to a controller.

•

Chapter 9, “M

onitoring System Events and Storage Devices,”

explains how the MegaRAID Storage Manager software monitors the

status of storage configurations and devices and displays information

about them.

•

Chapter 10, “Maint

aining and Managing Storage Configurations,”

describes the MegaRAID Storage Manager maintenance functions

for virtual drives and other storage devices.

•

Appendix A, “Eve

nts and Messages,” provides descriptions of the
