Virtual Disk and RAID Array

The virtual disk is a software component that emulates a physical disk to the appliance operating system.

Create only one virtual disk, regardless of the RAID level.

The RAID level must use a maximum of two physical disk spans, except RAID 10 which defaults to mirrored pairs. RAID arrays have equal numbers of physical disks in each horizontal span. Two physical disk spans are the most space-efficient configuration.

The physical disks per span for a nested RAID 50 or 60 array are half the total of the array's physical disks.

The PD per Span field (in the screens below) is N/A for nested RAID 10. It uses the RAID 10 default (mirrored pairs).

Important - If you change to an optional RAID level or change your RAID level to add optional disks, operational data is lost. Your current virtual disk and RAID array are deleted. Your backups must restore data to a new virtual disk and RAID array.
