Configuring Arrays and Spares
9
Click Next . The Create Array - Advanced dialog box appears,
as shown in Figure 5-5.
10
Select dedicated spares if desired. The disks in the list are the
available disks you did not select as array members. The
spare(s) you select should be at least as large as the smallest
array member. Otherwise the usable capacity of each array
member will be reduced to the capacity of the spare.
Note:
We recommend using a spare pool instead of
dedicated spares. See Creating Dedicated Spares or a
Spare Pool on page 5-14 for more information. Spares
in a spare pool can be used by any suitable array on the
controller.
11
Select Cache Enabled to enable cache for the array. If the
cache-enabled checkbox is greyed out, this means that no cache
is available. If caching is available but you don’t want to assign
any, deselect the cache Enabled checkbox.
12
The assigned checkbox indicates the total number of blocks
available for caching.
