    摘要: A storage system is configured to manage a pool to which multiple virtual volumes (VVOLs) are associated, assign a real area (RA) from any tier in an available tier pattern associated with a write-destination VVOL to a write-destination virtual area (VA), and carry out a reassignment process for migrating data inside the RA to an RA of a different tier, based on an access status of the RA. A management system is configured to assume a specified tier has been removed from the available tier pattern of a target VVOL, predict performance of all VVOLs associated with the pool to which the target VVOL is associated, determine whether there is a VVOL for which predicted performance is lower than a required performance, and when such a VVOL does not exist, instruct the storage system to remove the specified tier from the available tier pattern of the target VVOL.

    摘要: A storage apparatus includes a storage unit for storing data read/written by a host computer and provides the host computer with a storage area of the storage unit as one or more volumes. The storage management computer includes a first memory for storing task information including contents of an operation process performed on the storage apparatus, as well as a scheduled starting time and scheduled termination time of a process, and, in the case where first task information is stored in the first memory, when resources used in the process of second task information stored in the first memory are the same as resources used in the process of the first task information, the storage management computer computes times required for executing the first task information and the second task information, based on a time during which the processes of the first and second task information conflict with each other.

    摘要: A storage system manages a pool to which multiple VVOLs (virtual logical volumes conforming to thin provisioning) are associated, assigns a real area (RA) from any tier in an available tier pattern associated with a write-destination VVOL to a write-destination virtual area (VA), and carries out a reassignment process for migrating data inside this RA to an RA of a different tier than the tier having this RA based on the access status of the RA assigned to the VA. A management system assumes that a specified tier has been removed from the available tier pattern of a target VVOL, predicts the performance of the target VVOL and all the other VVOL associated with the pool to which the target VVOL is associated, determines whether or not there is a VVOL for which the predicted performance is lower than a required performance, and when such a VVOL does not exist, instructs the storage system to remove the specified tier from the available tier pattern of the target VVOL.

    摘要: A storage system assigns a real area from a pool to a virtual area in a virtual volume, and stores data into the real area. The pool comprises a plurality of real areas based on a plurality of types of storage devices with different characteristics, and the plurality of real areas are managed as a plurality of tiers depending on the characteristics of the storage devices. Moreover, the storage system moves the data from one tier to another tier in the pool, for each real area.
