vRanger 7.8.5 - Integration Guide for NetVault SmartDisk

Displays a list of the config command options and their syntax.

Displays the current values for the NetVault SmartDisk configuration.

Enables or disables NetVault SmartDisk Deduplication.

Enables or disables compression of NetVault SmartDisk-unique chunks. Disabled by default, compressing unique chunks can reduce their storage footprint up to 50%. Compression is performed on the unique chunks that result from the deduplication process. Compressing the initial Full Backup for a data set might take longer than not compressing the unique data because most of the data is considered unique. Subsequent Full Backups have fewer unique chunks and do not experience an increase in the amount of time it takes to complete the deduplication and compression process.

Sets the NetVault SmartDisk Deduplication Window by specifying the times that deduplication can be performed. By default, the default deduplication window is set to Anytime.

Available parameters include:

Sets the Garbage Collection window by specifying the times that NetVault SmartDisk Garbage Collection has priority over deduplication. By default, the Garbage Collection window is set to 13:00 through 19:00 on Mondays through Thursdays.

Available parameters include:

Specifies the maximum number of segments that can be deduplicated simultaneously.

Specifies the capacity, in megabytes per second (MBps), of the network between the NetVault SmartDisk Device and the backup clients.

Specifies the number of data streams that can be processed simultaneously.

Extends NetVault SmartDisk Storage Pools by adding or updating existing volumes in the NetVault SmartDisk Storage Pools. For more information, see Extending NetVault SmartDisk Storage Pools.

Modifies the port that the NetVault SmartDisk Device uses to communicate with vRanger. For more information, see Modifying the data port.

Used with ‑‑add, modifies the port that the NetVault SmartDisk Device uses to communicate with vRanger. For more information, see Modifying the data port.

Modifies the port that the NetVault SmartDisk Device uses to communicate with the backup software. For more information, see Modifying the data port.

Indicates when to calculate MD5 checksum for data streams written to NetVault SmartDisk.

Specifies the path for the file-system path of the volume to be used as a NetVault SmartDisk Storage Pool. You can specify local drives or Universal Naming Convention (UNC) paths for CIFS, NFS, and Storage Area Network (SAN). If the volume is on a mounted file system, verify that the specified path is a valid subdirectory on the mounted file system, and not the mounted directory itself. This step ensures that data is not written to the local directory if the mounted location is unavailable.

Specifies the percentage of the volume that NetVault SmartDisk can use; the remainder cannot be used by NetVault SmartDisk.

The value of ((100 - X) / 100) * (total volume size) is added to the Last Resort Threshold (LRT). In addition, a small amount of storage is reserved to complete Garbage Collection. These three components of reserved storage determine the total storage set aside that cannot be directly used by NetVault SmartDisk.

For example, if volume-size is set to 30 and the volume’s size is 100 GB, 70 GB is set aside — in addition to the LRT and Garbage Collection reserve space — and cannot be used by NetVault SmartDisk.

Specifies the maximum number of backup segments for the specific volume that can be deduplicated simultaneously. Defaults to 4.

Specifies the Label assigned to the Storage Pool. Defaults to a system-generated numeric label. Specify an existing Storage Pool label to add the volume to an existing Storage Pool, or specify a new name to create a Storage Pool.

Specifies the number of bytes reserved by the processes streaming data into NetVault SmartDisk. A smaller size results in NetVault SmartDisk having to reserve space more frequently; a larger size renders more disk space temporarily unavailable. If the Space.Available — reported through the show option — is less than the reservation-size, the volume is considered FULL.

Specifies which Storage Pool Roles the volume is available to perform. To specify multiple roles, list the ‑‑favour parameter multiple times. For example:

Use with ‑‑deny to dedicate a volume to one or more roles.

Specifies which Storage Pool Roles the volume is not available to perform. To specify multiple roles, list the ‑‑deny parameter multiple times.

For example:

Use with ‑‑favour to dedicate a volume to one or more roles.

Instructs NetVault SmartDisk to use the volume with either the most space available or the least activity occurring. If used with ‑‑favour and ‑‑deny, ‑‑balancing is applied last.

Required for Windows® platform when specifying UNC paths. Specifies the user account with read and write permissions to the UNC path.

Required for Windows platform when specifying UNC paths. Specifies the password for the user account with read and write permissions to the UNC path. This password is case-sensitive.
