  • Patent number: 11720264
    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.

  • Patent number: 11714751
    Abstract: In a complex system including; one or more storage systems including a cache and a storage controller; and one or more storage boxes including a storage medium, the storage box generates redundant data from write data received from a server, and writes the write data and the redundant data to the storage medium. The storage box transmits the write data to the storage system when it is difficult to generate the redundant data or it is difficult to write the write data and the redundant data to the storage medium. The storage system stores the received write data in the cache.

  • Patent number: 11698857
    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: 11675545
    Abstract: One or a plurality of physical storage devices that provide a physical storage area are connected to first and second computers. The computer updates metadata indicating the address correspondence relationship between the logical address of the volume and the physical address of the physical storage area in the write processing performed based on a write request designating the volume. The first computer copies the metadata to the second computer while receiving the write request. When the address correspondence relationship indicated by the copied metadata portion is changed during copying of the metadata, the first computer updates the metadata portion and copies the metadata portion to the second computer.

  • Publication number: 20230153008
    Abstract: Even without a first storage system does not have compatibility with a second storage system that is different from a default cloud storage service which can be accessed by a cloud computer service as a migration destination of a computer instance, a volume in the first storage system can be migrated to the second storage system. A system causes a migration tool of a cloud computer to migrate, from a first storage system to the cloud computer, a system volume storing an image of an OS for configuring a computer instance to be migrated, and a data volume storing data used by the OS, and creates a mapping volume, which has been mapped to the data volume migrated to the cloud computer with the migration tool, in a second storage system, and sets a path of data input/output from the computer instance to the mapping volume in the computer instance.
