Identifying RAID levels


A Redundant Array of Independent Disks (RAID) combines multiple physical disks into a single unit of storage. The advantages in speed, reliability, and capacity can be realized depending on which RAID level is selected. RAID provides the first level of protection against data loss due to a disk failure.

How to do it...

In order to select the proper RAID level to support the virtual workloads, you need to perform the following steps:

  1. Identify the different RAID levels and capabilities.

  2. Select an appropriate RAID level to support a virtualized workload based on capacity and performance requirements.

How it works...

RAID0 stripes disks together to appear as a single disk with a capacity equal to the sum of all the disks in the set. RAID0 provides excellent performance and capacity efficiency, but offers no data protection. If a disk fails in a RAID0 set, the data is lost and must be recovered from a backup or some other source. Since this level offers no redundancy, it is...
