2. In the User Space group box:
a.
Size - Enter the size of the volume. Change the Size list value to MiB or TiB as applicable.
The default is GiB.
NOTE: Minimum permitted volume size is 256MiB, maximum is 16TiB.
b. If the volume is Fully Provisioned from PDs:
i.
Device Type - Select FC for Fibre Channel drives, NL for Nearline drives, or SSD for
Solid State drives.
ii. Device RPM - Select the appropriate speed or .
NOTE: The Device RPM number does not represent a rotational speed for the drives
without spinning media (SSD). It is meant as a rough estimation of the performance
difference between the drive and the other drives in the system. For FC and NL drives,
the number corresponds to both a performance measure and actual rotational speed.
For an SSD drive, the number is to be treated as relative performance benchmark
that takes into account in I/O per second, bandwidth, and the access time.
iii. RAID Type - Select the appropriate RAID type for the volume.
iv.
Set Size - Select the appropriate set size.
