ReadCache Keyword
ReadCache indicates whether the array uses read caching.
Possible values are:
Yes (the default)—Enable read caching.
No—Disable read caching.
Example
ReadCache=Yes
Size Keyword
The Size keyword specifies the size of the array. Specify Maximum
(the default) to create an array using the maximum available space,
based on the array type and drives selected. Otherwise, specify the
size as an integer or a decimal number, followed by the unit
keyword MB (megabytes), GB (gigabytes), or TB (terabytes).
Note: A unit keyword is required with a numeric size value. If
no unit keyword is specified, the ACU exits with an error.
Examples
Size=2.5GB
Size=300MB
Size=Maximum
StripeSize Keyword
Note: This keyword does not support RAID 50 arrays because
RAID 50 arrays support only a stripe size of 64 KB.
The StripeSize keyword specifies the stripe size (in MB) written
to each member of a striped (RAID 0, RAID 5, RAID 10) array.
The possible values for StripeSize are 16, 32, 64, 128, 256 KB (the
default), 512 and 1024.
Example
StripeSize=256
