Provision Select how storage space is provisioned. Make a selection from the drop-down list:
• 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:
overallocated LUN resides so you do not run out of storage space unexpectedly.
Note:
of critical data. Instead, use a thick LUN.
Size Specify the size of the LUN. The maximum size that you can allocate to the LUN is stated
at the bottom of the screen.
