Explanation:

XtremIO XVC (XtremIO Virtual Copies) allows for efficient snapshot management and operations, including the refresh of volumes. One of the key features of XVC is that it enables the refresh of a production volume from a snapshot without requiring the volume to be unmounted from the host. This capability is designed to minimize disruption and maintain continuous availability of data to applications during refresh operations. The refresh operation is handled within the XtremIO storage array, and the production volume remains accessible to the host during this process1.

The Dell XtremIO Design Achievement document provides information on the capabilities and features of XtremIO X2 systems, including XVC operations1.

Additional details on XVC refresh operations can be found in the support documentation for the XtremIO Family on Dell's official website2.
