E.1.2 Basic Size when Using the Default Stripe Depth Value (For WSV Type Volumes)
When using the default Stripe Depth value, refer to the following table for basic size:
■ Basic size of each RAID group when using the default Stripe Depth value
For WSVs, the basic size is a multiple of the number of concatenations (the number of RAID groups that are to
be concatenated).
When the Wide Stripe Size is "Normal"
