OpenStorage disk pool properties

The properties of an OpenStorage disk pool may vary depending on the purpose the disk pool. The following table describes the possible properties:

Table: OpenStorage disk pool properties

Property

Description

Name

The disk pool name.

Storage server

The storage server name.

For disk appliance storage, the storage server is the disk appliance host.

Replication source

Indicates that the disk pool is a source for replication.

Replication target

Indicates that the disk pool is a target for replication.

Disk volumes

For disk appliance storage, the disk volumes that comprise the disk pool.

Total size

The total amount of space available in the disk pool.

Total raw size

The total raw, unformatted size of the storage in the disk pool.

The storage host may or may not expose the raw size of the storage.

Comment

A comment that is associated with the disk pool.

High water mark

The High water mark setting is a threshold that triggers the following actions:

  • When an individual volume in the disk pool reaches the High water mark, NetBackup considers the volume full. NetBackupchooses a different volume in the disk pool to write backup images to.

  • When all volumes in the disk pool reach the High water mark, the disk pool is considered full. NetBackup fails any backup jobs that are assigned to a storage unit in which the disk pool is full. NetBackup also does not assign new jobs to a storage unit in which the disk pool is full.

  • NetBackup begins image cleanup when a volume reaches the High water mark; image cleanup expires the images that are no longer valid. For a disk pool that is full, NetBackup again assigns jobs to the storage unit when image cleanup reduces any disk volume's capacity to less than the High water mark.

The default is 98%.

Low water mark

The Low water mark is a threshold at which NetBackup stops image cleanup.

The Low water mark setting cannot be greater than or equal to the High water mark setting.

The default is 80%.

Limit I/O streams

Select to limit the number of read and write streams (that is, jobs) for each volume in the disk pool. A job may read backup images or write backup images. By default, there is no limit.

When the limit is reached, NetBackup chooses another volume for write operations, if available. If not available, NetBackup queues jobs until a volume is available.

Too many streams may degrade performance because of disk thrashing. Disk thrashing is excessive swapping of data between RAM and a hard disk drive. Fewer streams can improve throughput, which may increase the number of jobs that complete in a specific time period.

per volume

Select or enter the number of read and write streams to allow per volume.

Many factors affect the optimal number of streams. Factors include but are not limited to disk speed, CPU speed, and the amount of memory.
