• 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. • Percent Full-When the snapshot repository virtual disk reaches the userspecified repository full percentage level, the event is logged in the Major Event Log (MEL). The default snapshot repository full percentage level is 50% of the source virtual disk. • Snapshot Repository Virtual Disk Full Conditions-Choose whether to fail writes to the source virtual disk or fail the snapshot virtual disk when the snapshot repository virtual disk becomes full. • Host-to-Virtual Disk Mapping-Choose whether to map the snapshot virtual disk to a host or host group now or to map the snapshot virtual disk later. The default setting is Map later. 150 Configuration: Premium Feature-Snapshot Virtual Disks
