OpenStorage disk pool properties
Table 11-3
Description
The disk pool name.
The storage server name.
For disk appliance storage, the storage server is the disk appliance host. For Nirvanix
cloud storage, the storage server is nirvanix.com.
For disk appliance storage, the disk volumes that comprise the disk pool.
The total amount of space available in the disk pool.
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.
A comment that is associated with the disk pool.
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image cleanup expires the images that are no longer valid.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%.
