Physical storage

NotesDescriptionItem

You are prevented from setting the size

below 15 MB.

After 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 and local storage

applications without an enforced

allocated limit. If there is unused

storage space on the logical disk where

a component without an enforced

allocated limit resides, data can be

written to the component until the

logical disk is full.

The amount of storage that ASM allocates to the

application component, user-defined application, or

shared folder you are configuring.

Size

You are able to choose SAS, (Serial

Attached SCSI) SATA, (Serial Advanced

Technology Attachment) or SCSI (Small

Computer System Interface) for a

physical disk type, depending on your

hardware.*

For more information about RAID levels,

see “Customizing RAID levels”

(page 20).*

Hard drive formatting that provides different levels

of performance, capacity, and data protection.

RAID level

A hot spare is assigned at the array

level. A LUN that does not require a hot

spare may be assigned one anyway if

another LUN on the same array requires

a hot spare. *

A hot spare is a hard drive reserved as a spare for

storage space configured as RAID 1, 1+0, 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.

Hot spare required

For better performance, increase the

minimum number of physical disks

The minimum number of physical disks that the

allocated storage will be spread across. Storage

may be provisioned across more disks, but this setting

determines the minimum number of disks reserved

for the allocated storage.

Minimum number of

physical disks

The storage area can be assigned to an existing

logical disk, or it can be assigned a new disk, which

is created upon completion of the scheduled tasks

for the storage wizard.

Assigned logical disk

ASM provides the following values: 8

KB, 16 KB, 32KB, 64 KB, 128 KB, and

256 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

This value may be modified in order to

match the change rate of the data in

the storage area.

Amount of storage space (as a percentage of the

volume) that is reserved for storing snapshots of the

storage area.
