■ The maximum number of volumes for each RAID Group
● For Open Volumes:
*1: "200GB (SSD)" and "400GB (SSD)" are Solid State Drives.
*2: "500GB (S)", "750GB (S)", "1TB (S)", and "2TB (S)" are Nearline SATA disk drives.
● For Mainframe Volumes:
*1: "73GB (SSD)", "146GB (SSD)" , and "200GB (SSD)" are Solid State Drives.
■ Cautions for Open volume creation
When creating multiple volumes in a RAID group, the full User Capacities are not always
secured.
Logical Volume sizes, which are set in MB, must be exact multiples of the base size in
order to fully utilize the available user capacity.
Setting the Logical Volume size to any multiple of the applicable "Lowest exact MB multiple of the
base size" value shown in the following table will allow the available capacity to be fully used.
