When jobs request virtual tape data residing on physical tape, the corresponding volume must be mounted and the data set migrated back to disk cache, causing a delay for all jobs requesting data not already in cache.

Virtual recall mount time is about 200 to 300 seconds for each recall. Even with a data center daily hit rate of 94 percent, the time savings can be significant. By eliminating thousands of small delays a day, VTAR can save hours a day in wait time.
