Table 5 Advanced Storage Properties items (continued)

Physical storage

NotesDescriptionItem

The percent full warning threshold is set

by default to 80%. Percent full warning

threshold values are ASM-specific;

percent full warning threshold values

selected in the Quota Management

MMC snap-in are not adopted by ASM.

All other Quota Management MMC

snap-in settings are adopted by ASM.

See “Setting a percent full warning

threshold” (page 21).

The percent full value that when reached changes

the storage status to Warning and issues a warning

alert. The warning indicates that storage use has

surpassed the percentage 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.

Percent full warning

threshold

This item is available for shared folders

and local storage component. See

“Enforcing an allocated storage limit

for shared folders and local storage

applications” (page 22).

Sets an enforced quota for the amount of storage

available to a shared folder or local storage

application. When the storage space allocated to a

component is full, no further data can be saved to

this component.

Enforce allocated limit

(quota)

This setting does not apply to shared

folders.

Indicates whether the storage area is hosted on a

mount point or drive letter.

*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 and local storage applications). However, you cannot change the RAID

level, RAID stripe size, Hot Spares, or Physical Disk Type.

Customizing RAID levels

Before you customize the default RAID level setting, review Table 6 (page 21) to see how the

different RAID levels affect performance, capacity, and data protection level.

Unless you customize the advanced configuration settings, the wizard configures the storage space

with the default values shown on the Advanced window:

• For Exchange and SQL Server, the wizard suggests default settings based on HP storage best

practices and specific recommendations for Exchange storage group and SQL Server database

components. You should generally accept these defaults.

• For user-defined applications and shared folders (where industry-standard recommendations

cannot be determined), the wizard provides default settings you can customize.

Table 6 (page 21) shows how the different RAID levels affect:

• Performance–The speed at which data is read from and written to the hard drives. The RAID

level with the best performance rating provides the fastest reads and writes.

• Capacity–The available storage space on the hard drives. The RAID levels with the best

capacity rating require the least amount of storage space to store data.

• Data protection–The number of hard drives that can fail without data being lost. The RAID

level with the best data protection rating allows more hard drives to fail before data is lost.
