NetVault SmartDisk 11.4.5 - Administration Guide

[SmartDisk:Deduplication Scheduler]

Statistics for the process that schedules deduplication activity.

Elements.Queued = <No.>

Number of segments awaiting deduplication.

Data.Queued = <No.>, B

Number of bytes awaiting deduplication.

Elements.Deduplicating = <No.>

Number of elements or backup segments currently deduplicating.

Data.Deduplicating = <No.>, B

Total size of elements or backup segments currently deduplicating. After all current deduplication completes, the equivalent amount of data is removed from the Staging Store.

Deduplication Available = TRUE

Displays TRUE or FALSE depending on whether the CSD is available for deduplication tasks.

Deduplication Enabled = TRUE

Displays TRUE or FALSE depending on whether the data-deduplication option is licensed and enabled.

GC Enabled = TRUE

Displays TRUE or FALSE depending on whether Garbage Collection is enabled. Disabling Garbage Collection overrides the existing Garbage Collection Window configuration. If disabled, it does not run even if it is required and the Deduplication Engine is available.

GC Required = FALSE

Displays TRUE or FALSE depending on whether Garbage Collection is needed. Garbage Collection is required after data has been deduplicated or retired from storage.

GC Active = FALSE

Indicates whether Garbage Collection is active.

GC Start In = <No.>

Current number of seconds remaining before Garbage Collection might start. This statistic is only displayed if GC Required = TRUE. Also, even if the field displays 0, it indicates that collection can start at the next permitted opportunity; it does not indicate that it will.

[SmartDisk:RAS Controller]

Statistics for the process that interacts with your backup software.

Availability Score = <No.>

Indicates how available a backup server should consider this NetVault SmartDisk Device to be. The lower the number, the less available the NetVault SmartDisk Device is. Given a choice of two NetVault SmartDisk Devices to target a backup job to, your backup software might choose the one with the higher Availability Score. The score takes the following into account:

Sent MBps = <No.>

Total megabytes per second (MBps) across all streams being sent out from NetVault SmartDisk to your backup software; that is, when a restore job is being performed.

Received MBps = <No.>

Total MBps across all streams being sent to NetVault SmartDisk; that is, when a backup job is targeted to a NetVault SmartDisk Device.

Machine ID = <3-XXXX-XXX>

Machine ID of the NetVault SmartDisk Instance that is used to obtain a permanent license key.

Soft stream limit = <No.>

Current maximum number of data streams or backups that your backup software can target to this NetVault SmartDisk Device simultaneously.

streams = <No.>

Total number of elements or backup segments that have been deduplicated.

catalog_bytes = <No.>

Total number of bytes used by a volume’s catalog.

ondisk_bytes = <No.>

Total number of bytes on disk used by deduplicated data. Includes the bytes consumed by the Chunk Store, Chunk Index, and Manifests.

gc_reserve_bytes = <No.>

Number of bytes that NetVault SmartDisk must keep available on a file system to guarantee that Garbage Collection can take place. Increases as the size of the Chunk Store increases.

stream_bytes = <No.>

Total number of bytes submitted for deduplication.

csd.stream_bytes = <No.>

Total number of bytes submitted for deduplication since the NetVault SmartDisk Services were started. When a backup is retired, the size of the backups is not deleted from csd.stream_bytes.
