Search for. However, the response speed of the storage device decreases as the access frequency and the number of accesses to the disk area increase.

  For this reason, it is preferable that the storage apparatus obtains the data requested to be accessed from the cache area. Further, the higher the ratio of acquiring data from the cache area (cache hit rate), the higher the response speed of the storage apparatus.

  Patent Document 1 describes a technique for determining whether or not to store user environment information in a cache memory according to the priority set for each user. Specifically, in the technique described in Patent Document 1, when the user priority satisfies a predetermined condition (the priority is high), the user environment information is held in the cache memory. On the other hand, in the technique described in Patent Literature 1, when the user priority does not satisfy a predetermined condition (the priority is low), the user environment information is deleted from the cache memory. In Patent Document 1, user environment information means information for realizing a virtual desktop environment for each user on a virtual PC (Personal Computer).
