RAID Setup
This chapter discusses the various types of RAID arrays, their applications,
including performance and reliability considerations, and general maintenance
information. Given the variety of applications for RAID systems, the various RAID
levels each have advantages and disadvantages.
Determining what RAID level to use for your system is an important step. To help
guide you, we have divided this chapter into four parts:
•
Application Scenarios describe different types of RAID system usage and
match them to appropriate RAID configurations.
•
RAID Implementation is for those systems which don’t match well with our
given application scenarios. The section covers general principles of each
possible RAID level, and what types of system usage would benefit from those
levels.
•
RAID Management & Operations covers various fault scenarios,
rebuilding/synchronization of drives, and drive partitioning/formatting which may
be encountered during typical use.
•
Configuration Ideas cover organizational models of array systems that use the
previously-documented array types. It also points out additional advantages of
various options.
This is certainly not intended as a complete, nor definitive reference on RAID
technology applications, but merely serves as a first step to understanding the
principles and proper usage of RAID. Please see Appendix A: Technology
Background for more details on the functionality of RAID systems.
