HP StorageWorks All-in-One SB600c Storage Blade - Manual (Page 27)

NOTE:
After storage space is allocated and configured using a wizard, only the following storage configuration
settings can be changed:
• Allocated space size
• Percent full warning threshold
• Enforce Allocated Limit (shared folders only)
Once a logical disk is created, its configuration cannot be changed.
Selecting advanced configuration settings
Use the Advanced window in the wizard to change the allocated space size and default advanced
configuration settings for each application component, user-defined application, and shared folder listed.
After storage is configured using a wizard, you can access the Advanced window from the Allocate
Space Wizard and change the allocated space size, percent full threshold warning, and/or enforce
allocated limit (shared folders only) values as needed.
NOTE:
When allocating storage on an AiO400 Storage System that does not have additional external storage,
most of the default advanced configuration settings cannot be changed. This is because the AiO400
Storage System is pre-configured with one volume and one logical disk, and ASM is unable to create
any new logical disks on the system. All storage allocated is allocated from the existing logical disk.
Table 6 provides a brief description of the items you can modify:

Item Description Notes
Size
The amount of storage that ASM allocates
to the application component, user-defined
application, or shared folder you are
configuring.
You are prevented from setting the
size below 15 MB.
nl NOTE:
Once the allocated storage
space is full (100 percent used),
no further data can be stored to
the space until you increase the
size using the Allocate Space
Wizard. The only exception is
for shared folders without an
enforced allocated limit. If there
is unused storage space on the
logical disk where a shared
folder without an enforced
allocated limit resides, data can
be written to the shared folder
until the logical disk is full.
RAID Level
Hard drive formatting that provides different
levels of performance, capacity, and data
protection.
For more information about RAID
levels, see Customizing RAID
levels on page 28.*
RAID Stripe Size
The number of bytes or kilobytes of data in
each RAID stripe (block of data). The RAID
stripe size selected affects performance.
nl For the best performance, select the stripe size
closest to the size of the files being saved.
ASM provides the following
general values: small (8 kB),
medium (16 kB), and large (64
kB).*
