摘要： A storage system for controlling attributes for data stored in virtual storage areas includes a logical storage area management unit 1140 that manages the linking of virtual storage areas and attributes such as encryption attributes to logical storage area groups. When receiving a command to change an attribute of a virtual storage area or virtual volume, the logical storage area management unit determines the presence or absence of a unit logical storage area in a logical storage area group or pool linked to a different attribute and that is not yet allocated to a virtual storage area. The logical storage area management unit links a unit logical storage area determined to be present to a virtual storage area, reads data stored in the unit logical storage area linked to a virtual storage area subjected to an attribute change, and stores the read data in accordance with the different attribute.

摘要： A management system is coupled to a storage system group including a scale-out storage system (a virtual storage system). The management system has storage management information, which includes information denoting, for each storage system, whether or not a storage system is a component of a virtual storage system. The management system, based on the storage management information, determines whether or not a first storage system is a component of a virtual storage system, and in a case where the result of this determination is affirmative, identifies, based on the storage management information, a second storage system, which is a storage system other than the virtual storage system that includes the first storage system, and allows a user to perform a specific operation only with respect to this second storage system.

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 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.
