Storage Array Performance During Virtual Disk
Copy
The following factors contribute to the overall performance of the storage
array:
• I/O activity
•Virtual disk RAID level
• Virtual disk configuration—Number of drives in the virtual disk groups
• Virtual disk type—Snapshot virtual disks may take more time to copy than
standard virtual disks
During a virtual disk copy, resources for the storage array are diverted from
processing I/O activity to completing a virtual disk copy. This affects the
overall performance of the storage array. When you create a new virtual disk
copy, you define the copy priority to determine how much controller
processing time is diverted from I/O activity to a virtual disk copy operation.
