摘要: The present invention concerns allocating files in storage apparatuses efficiently while satisfying requirements of the files. An information system 1 includes a first server system 3a coupled to a first storage apparatus 10a, a second server system 3b coupled to a second storage apparatus 10b, and a third server system 3c coupled to a third storage apparatus 10c. When the first server system 3a receives a data I/O not needing access to the entity of a file responds to the data I/O request using metadata of the file and when the first server system 3a receives a data I/O needing access to the entity of a file acquires the entity of the file from the second storage apparatus 10b or the third storage apparatus 10c to process the data I/O request. The first server apparatus determines the allocation target of the entity of the files on the basis of a requirement set for the files and information relating to configurations of the storage apparatuses 10.

摘要: With this storage apparatus and its control method for presenting multiple virtual volumes to a host apparatus and dynamically allocating to each of the multiple virtual volumes a physical storage area for storing data according to the usage status of each of the multiple virtual volumes, the importance set to each of the multiple virtual volumes is managed, and a storage area is dynamically allocated to each of the multiple virtual volumes. Here, upon dynamically allocating the storage area to each of the multiple virtual volumes, a storage area provided by a plurality of memory apparatus groups respectively configured from a plurality of memory apparatuses is allocated to one or more virtual volumes with low importance among the multiple virtual volumes, and a storage area provided by one of the memory apparatus groups is allocated to other virtual volumes among the multiple virtual volumes.
