Learn About Virtual Disk Copy and Performance

During a , data is read from the  and written to the  in the same . Because the virtual disk copy diverts  processing resources from I/O activity, it can affect I/O activity on the storage array. The  defines how much processing time is allocated for a virtual disk copy as compared to I/O activity.

Virtual Disk Copy Priority Rates

Several factors contribute to system performance, including I/O activity,    level, virtual disk configuration (the number of physical disks in the  or cache parameters), and virtual disk type (  might take more time to copy than ).

You can select the copy priority while you are creating a new virtual disk copy, or you can change it later using the . The following copy priority rates are available:

• Lowest
• Low
• Medium
• High
• Highest

The lowest priority rate supports I/O activity, but the virtual disk copy takes longer. The highest priority rate supports the virtual disk copy, but I/O activity might be affected.

Viewing the Progress of a Copy Operation

The progress of the virtual disk copy is displayed in the status bar at the bottom-right of the Copy Manager. The status bar shows an estimate of the time remaining for the virtual disk copy to complete. You can view the progress of a virtual disk copy in the Copy Manager only when a virtual disk copy has a status of In Progress.
