Growth
Warning
set the threshold when the LD space exceeds this amount.
Growth Limit
set the threshold at which the system stops creating additional LDs to
support volumes that draw space from a CPG.
Device Type
set the disk type to Fibre Channel (FC), Nearline (NL), or Solid State
(SSD).
Device Speed set the disk speed.
Note: The Device Speed 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.
RAID Type set the VV's RAID type.
Set Size specify the VV's set size.

Override checKiBox allow users to modify that property's value when applying the
template.

template, Allocation Settings screen:

Availability
set the level of failure tolerance for a volume created with this
template. Choices are Cage - default, Port, Magazine.
Step Size
determine the number of contiguous bytes that the system accesses
before moving to the next chunklet within logical disks supporting
volumes created with this template. From the Step Size list, select 32,
