Chapter 6 

 

- 102 - 

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.
