Preface 1
Preface
This document explains 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 document has the following chapters and appendixes:
•Chapter 1, “Overview,” 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 Encryption,” 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, “MegaRAID 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, “MegaRAID Storage Manager Overview and Installation,”
introduces the main features of MegaRAID Storage Manager
software and explains how to install it.
•Chapter 7, “MegaRAID Storage Manager Window and Menus,”
describes the layout of the MegaRAID Storage Manager window and
lists the available menu options.
•Chapter 8, “Configuration,” 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, “Monitoring 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, “Maintaining and Managing Storage Configurations,”
describes the MegaRAID Storage Manager maintenance functions
for virtual drives and other storage devices.
•Appendix A, “Events and Messages,” provides descriptions of the
MegaRAID Storage Manager events.
•Appendix B, “Glossary,” contains definitions of storage-related terms.
Conventions
Note: Notes contain supplementary information that can have an
effect on system performance.
Caution: Cautions are notifications that an action has the potential to
adversely affect equipment operation, system performance,
or data integrity.
•Appendix C “Notices,” contains Notices information.
