For more information about RAID
levels, see “
Hard drive formatting that provides different
levels of performance, capacity, and data
protection.
RAID Level
ASM provides the following general
values: small (8 kB), medium (16
kB), and large (64 kB).*
The number of bytes or kilobytes of data in each
RAID stripe (block of data). The RAID stripe size
selected affects performance. For the best
performance, select the stripe size closest to the
size of the files being saved.
RAID Stripe Size
The percent full warning threshold
is set by default to 80%. Percent full

warning threshold values are
issues a warning alert. The warning indicates
ASM-specific; percent full warning
that storage use has surpassed the percentage
threshold values selected in the
full value. For example, if you enter 75%, you
see a warning (yellow asterisk) in the content
pane when storage is at 75 percent full.

folder you are configuring. The number of hard
drives dedicated depends on the allocated
space size and other advanced storage
configuration settings selected for the item you
are configuring. Exclusive storage is required
by some applications for the storage of specific
types of data.
This item is available for shared
folders only. See “
allocated storage limit for shared
folders
Sets an enforced quota for the amount of storage
available to a shared folder. When the storage
space allocated to a shared folder is full, no
further data can be saved to the shared folder.

5, or 6. A hot spare automatically replaces a
hard drive when it fails. When the failed hard
drive is replaced, its replacement becomes the
new hot spare.
You are able to choose SAS, (Serial
Attached SCSI) SATA, (Serial

or SCSI (Small Computer System
Interface) for a physical disk type.
*After you have allocated and configured storage for an application component, user-defined application,
or shared folder using a wizard, you can change the allocated space size, change the percent full warning
threshold, and change the enforced allocated limit (shared folders only). However, you cannot change the
RAID level, RAID stripe size, Hot Spares, or Exclusive Storage settings. This is due to the nature of how hard
drives work.
