DescriptionItem
Select how storage space is provisioned. Make a selection from the
menu:
•
Thin. Even though you specify the size of the LUN when you create it,
storage space is assigned on demand instead of up front. The size of
the LUN is reported as the total storage space that you specify when
you create the LUN.
•
Thick. All storage space that you specify when you create the LUN is
also allocated up front. The size of the LUN is reported as the total
storage space that you specify when you create the LUN. This is the
default method.
Note: Make sure that you watch the volume capacity of the volume on
which the overallocated LUN resides so that you do not run out of storage
space unexpectedly.
Note: We recommend that you do not use an overallocated thin LUN
for storage of critical data. Instead, use a thick LUN.
Provision
