  • Publication number: 20230297242
    Abstract: A storage device manages data stored in a storage drive in a plurality of logical hierarchies. The plurality of logical hierarchies include a writing hierarchy above a hierarchy of a parity group including a plurality of storage drives. The storage device writes received host data in a free area in the writing hierarchy. In the data recovery process for replacing a failure storage drive with a new storage drive, the storage device executes the garbage collection process on a first logical area in the writing hierarchy associated with the first parity group including the failure storage drive. In the garbage collection process, valid data is selected from the first logical area and copied to a second logical area associated with a second parity group different from the first parity group.

  • 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: 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.
