Chapter 8 Disk Array
Purpose
Disk array is a data storage virtualization technology that combines multiple physical disk drive
components into a single logical unit. An array stores data over multiple HDDs to provide enough
redundancy so that data can be recovered if one disk fails. Data is distributed across the drives in one
of several ways called "RAID levels", depending on what level of redundancy and performance is
required.
