  • Patent number: 10747440
    Abstract: It is provided a storage system comprising at least one controller and a storage device. The at least one controller verifies, for each predetermined storage area within a logical volume provided to the host computer, whether data of the each predetermined storage area is duplicated to another storage area. The storage device holds unshared data associated only with the storage area and shared data associated with the storage area and the another storage area in the case where the data of the each predetermined storage area is identical to the data of the another storage area. The at least one controller reads the unshared data in the case where a request to read the data is received under a state in which the unshared data and the shared data are held, and releases an area in which the unshared data is stored at predetermined timing.

  • Patent number: 10733092
    Abstract: A storage system monitors the first access frequency of occurrence which is the access frequency of occurrence from a host device during a first period, and the second access frequency of occurrence which is the access frequency of occurrence from a host device during a second period shorter than the first period. Along with performing data relocation among the tiers (levels) in the first period cycle based on the first access frequency of occurrence, the storage system performs a decision whether or not to perform a second relocation based on the first access frequency of occurrence and the second access frequency of occurrence, synchronously with access from a host device. Here the threshold value utilized in a decision on whether or not to perform the first relocation is different from the threshold value utilized in a decision on whether or not to perform the second relocation.

  • Patent number: 10725865
    Abstract: A storage unit includes a plurality of storage devices that form a RAID group, that are coupled to the same bus, and that communicate with each other. Each of the plurality of storage devices includes a device controller and a storage medium. The plurality of storage devices store each of data and parities generated on the basis of the data, the data and the parities being included in RAID stripes. A first device controller of a first storage device included in the RAID group transmits, to the plurality of storage devices included in the RAID group other than the first storage device, an instruction to transfer the data and/or the parities included in the RAID stripes and restores the data or the parity corresponding to the first storage device of the RAID stripes on the basis of the transferred data and the transferred parities.

  • Publication number: 20200210082
    Abstract: One or more storage systems are connected to one or more storage boxes comprising multiple storage devices. Multiple storage areas provided by one or more storage boxes include an allocated area, which is a storage area that is allocated to a virtual volume, and an empty area, which is a storage area that is not allocated to any logical volume. Multiple owner rights corresponding to multiple storage areas are set in one or more storage systems. A storage system having an empty area owner right changes an empty area to the allocated area by allocating the empty area. In a case where a configuration change (a relative change in the number of storage boxes with respect to the number of storage systems) is performed, a first storage system that exists after the configuration change sets, in the first storage system, either more or fewer owner rights than the owner rights, which have been allocated to the first storage system before the configuration change.
