The Create Storage Pool Wizard opens.
You cannot select disks from multiple expansion units.
All data on the selected disks will be deleted.
Storage & Snapshots displays all RAID types that match the number of selected disks and automatically selects the most optimized RAID type.

Use the default RAID type if you are unfamiliar with the technology.
For details, see RAID Types.
The designated hot spare automatically replaces any disk in the RAID group that fails.
For RAID 50 or RAID 60, a spare disk must be configured later. You should configure a global spare disk so that all sub-groups share the same spare disk. For details, see Configuring a Global Hot Spare.
The selected disks are divided evenly into the specified number of RAID 5 or 6 groups.
A higher number of sub-groups results in faster RAID rebuilding, increased disk failure tolerance, and better performance if all the disks are SSDs.
A lower number of sub-groups results in more storage capacity, and better performance if all the disks are HDDs.
If a RAID group is divided unevenly, the excess space becomes unavailable. For example, 10 disks divided into 3 sub-groups of 3 disks, 3 disks, and 4 disks will provide only 9 disks of storage capacity.
The Pool Creation Summary window opens.
A confirmation message appears.
All data on the selected disks will be deleted.
QTS creates the storage pool and then displays the information on the Storage/Snapshot screen.
