Virtual Disks 253
• Across connectors in the enclosure that are not at the same level
of the enclosure but with a physical disk of acceptable size
difference
If the size difference is not acceptable, the disk is not mirrored and
hence dropped from the span, and number of span and disk in the
span is recalculated.
NOTE: It is recommended that you use Intelligent Mirroring to create RAID 10
across enclosures for simple and optimum configuration.
NOTE: To view the redundancy across enclosures achieved through
Intelligent Mirroring, click the virtual disk and view the physical disk IDs in
each span, which are from alternate enclosures.
– Select RAID 50 to implement striping across more than one span of
physical disk s. RAID 50 groups n*s disks as one large virtual disk with
a capacity of s*(n-1) disks, where s is the number of spans and n is the
number of disks within each span.
– Select
RAID 60 to implement striping across more than one RAID 6
span. RAID 60 Groups n*s disks as one large virtual disk with a
capacity of s*(n-2) disks, where s is the number of spans and n is the
number of disks within each span. RAID 60 provides increased data
protection and better read performance, but slower write performance.
2 Select the Create Encrypted Virtual Disk check box to ensure only
encrypted physical disks are used to create the virtual disk.
