  • Publication number: 20150081964
    Abstract: Tier management is performed immediately in response to the priority level of an object. A priority level is determined for each of two or more objects included in a specific computer program. A physical memory area is extracted that is a relocation target for each of the two or more objects. Using a management apparatus, a specific physical memory area is selected from the physical memory areas that are relocation targets based on the priority level for each of the objects. The management apparatus instructs a storage apparatus to allocate data stored in the selected specific physical memory area to the physical memory area in a specific storage tier.

  • Patent number: 8543786
    Abstract: A computer system of the present invention selects and executes an appropriate action in a case where capacity of a pool that provides a real storage area to a virtual logical volume is insufficient. A management computer determines, based on a utilization status of each pool, whether or not there exists a prescribed pool that requires pool size expansion. The management computer, in a case where the prescribed pool is detected, selects at least any one of a volume addition method for adding an unused real volume to the prescribed pool and a data migration method for migrating data of the virtual logical volume to another pool other than the prescribed pool, and expands a pool size of the prescribed pool in accordance with the selected method.
