Media Server Deduplication Pool properties

Table: Media server deduplication pool properties describes the disk pool properties.

Table: Media server deduplication pool properties

Property	Description
Storage server	The storage server name. The storage server is the same as the NetBackup media server to which the storage is attached.
Storage server type	For a Media Server Deduplication Pool, the storage type is PureDisk.
Disk volumes	For a Media Server Deduplication Pool, all disk storage is exposed as a single volume. PureDiskVolume is a virtual name for the storage that is contained within the directories you specified for the storage path and the database path.
Total available space	The amount of space available in the disk pool.
Total raw size	The total raw size of the storage in the disk pool.
Disk Pool name	The disk pool name. Enter a name that is unique across your enterprise.
Comments	A comment that is associated with the disk pool.
High water mark	The High water mark indicates that the volume is full. When the volume reaches the High water mark, NetBackup fails any backup jobs that are assigned to the storage unit. NetBackup also does not assign new jobs to a storage unit in which the deduplication pool is full. The High water mark includes the space that is committed to other jobs but not already used. The default is 98%.
Low water mark	The Low water mark has no affect on the PureDiskVolume.
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. If you select this property, also configure the number of streams to allow per volume. 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.
