Configuration: Premium Feature—Snapshot Virtual Disks

Use the advanced path to choose whether to place the snapshot repository 

virtual disk on free capacity or unconfigured capacity and to change the 

snapshot repository virtual disk parameters. You can select the advanced path 

regardless of whether you use free capacity or unconfigured capacity for the 

snapshot virtual disk.
Using the advanced path, you can specify the following parameters for your 

snapshot virtual disk:

• Snapshot Virtual Disk Name—A user-specified name that helps you 

associate the snapshot virtual disk to its corresponding snapshot repository 

virtual disk and source virtual disk. 

• Snapshot Repository Virtual Disk Name—A user-specified name that 

helps you associate the snapshot repository virtual disk to its corresponding 

snapshot virtual disk and source virtual disk. 

• Capacity Allocation—This parameter allows you to choose where to create 

the snapshot repository virtual disk. You can allocate capacity by using one 

of the following methods: 
–

Use free capacity on the same disk group where the source virtual disk 

resides. 

–

Use free capacity on another disk group. 

–

Use unconfigured capacity and create a new disk group for the 

snapshot repository virtual disk. 

–

Dell recommends placing the snapshot repository virtual disk within 

the disk group of the source virtual disk. This ensures that if drives 

associated with the disk group are moved to another storage array, all 

the virtual disks associated with the snapshot virtual disk remain in 

the same group.

• Snapshot Repository Virtual Disk Capacity—The snapshot repository 

virtual disk capacity is expressed as a percentage of the source virtual disk 

capacity. The maximum percentage allowed is 120 percent.
