Enable and Disable a Volume RAID Preference
A PS Series group uses automatic performance load balancing (enabled by default) to identify the RAID level that provides the best
performance for a volume and store volume data on pool members with that RAID level, if such members are available.
Prerequisites
The following prerequisites and considerations apply:
• RAID 5 does not oer optimal data protection for business-critical data due to the higher risks of encountering a second drive
failure during a rebuild, and is therefore not recommended. You cannot congure RAID 5 using the Group Manager GUI; however,
it can be congured using the CLI.
• Thin clones inherit the RAID preference, if any, of the template volume. You cannot set a separate RAID preference for a thin
clone.
• You can override automatic performance load balancing by enabling a RAID level preference on a volume.
• If you enable a RAID preference, the group attempts to store volume data on pool members with that RAID level. The group still
uses capacity-based load balancing on the volume.
