vRanger 7.8 - Integration Guide for NetVault SmartDisk

Staging Store size

The maximum disk space required for the Staging Store is equal to the Size of the Weekly Full Backups.

Calculating Chunk Store size

The amount of physical disk space required for the Chunk Store is equal to the Unique Data Size. To calculate the Unique Data Size or the size of the Chunk Store, use the following formula:

Size of Weekly Full Backups + ((Size of Weekly Full Backups * Weekly Change Rate)

* Weekly Full Backup Retention Period)

+ (Size of Daily Backups * (Number of Daily Backups between Weekly Full Backups

* Daily Backup Retention Period))

Example:

100 GB = Size of Weekly Full Backups

12 = Weekly Full Backup Retention Period in Weeks

10 GB = Size of Daily Backups

4 = Daily Backup Retention Period in Weeks

6 = Number of Daily Backups between Full Backups

100 + ((100 * 0.1) * 12) + (10 * (6*4)) =

100 + ((10) * 12) + (10 * (24)) =

100 + (120) + (240) = 460 GB

Choosing a deployment location for a NetVault SmartDisk Instance

The third step in defining your NetVault SmartDisk Deployment Strategy is deciding where you want to deploy your NetVault SmartDisk Instances. Whether the NetVault SmartDisk Instance is enabled for deduplication dictates the available deployment options.

Reviewing deployment options for NetVault SmartDisk Deduplicated Instances

Multiple vRanger servers cannot target the same repository. For this reason, in environments with one or more vRanger servers, you must deploy a NetVault SmartDisk Instance for each vRanger server.

 

NOTE: You cannot deploy multiple NetVault SmartDisk Instances on the same machine.
