Abstract: An object of the invention is to appropriately separate an available cluster for each user in a storage system configured by using a plurality of clusters each of which is an aggregate of nodes. A computer system includes a plurality of K8s clusters each configured by one or a plurality of K8s nodes, a storage that provides a volume, and a tenant management unit that manages the plurality of the K8s clusters and the storage. The tenant management unit creates, in the storage, a plurality of tenants respectively corresponding to the plurality of the K8s clusters. The storage, for each of the plurality of the K8s clusters, permits access from the K8s cluster to a tenant corresponding to the K8s cluster and prohibits access from the K8s cluster to a tenant not corresponding to the K8s cluster.

Abstract: Examples implementations described herein involve systems and methods wherein the storage software is configured to consider the capabilities of the underlying hardware to determine the caching data method at run time. Some examples of capabilities that are considered in the example implementations include whether non-volatile memory (NVM) is available and how much NVM is available. Some examples of caching methods used include using both dynamic random access memory (DRAM) and NVM to cache write data and using only NVM to cache write data.

Abstract: A primary storage system is equipped with a local storage subsystem having a mirror volume of a volume in a primary storage subsystem, and a remote storage subsystem having a mirror volume of the volume in the primary storage subsystem at a secondary site. When storing a write data from a host to a volume, the primary storage subsystem determines an SEQ# to be stored in a journal corresponding to the write request, creates a journal including the relevant SEQ# and a replica of the write data, and transmits the relevant SEQ# to the local storage subsystem, which creates a journal including the relevant SEQ# and stores it in its own journal volume. But when creation of the journal including the relevant SEQ# is stopped, the local storage subsystem creates a dummy journal including the relevant SEQ# but not including the write data.

Abstract: Provided is a control method for a plurality of storage apparatuses that perform a migration from a pre-migration volume group to a post-migration volume group. The plurality of storage apparatuses are configured to accept a write command directed to any one of a plurality of volumes in the pre-migration volume group and the post-migration volume group when the migration is being processed. The control method includes writing write data of the write command to all of the plurality of volumes in a predetermined order, writing the write data to a last volume last among the plurality of volumes, and writing the write data to volumes different from the last volume after individually obtaining exclusive locks and, after completion of the writing the write data to the last volume, releasing the exclusive locks.

Abstract: A source remote copy configuration in a source storage system is migrated to a destination storage system as a destination remote copy configuration. The destination primary storage apparatus of the destination storage system defines a virtual volume mapped to the primary volume provided by the source primary storage apparatus which is a storage area of the virtual volume; takes over a first identifier of the primary volume to the virtual volume; transfers, when the virtual volume receives an access request, the access request to the source primary storage apparatus to write data in the primary volume; and takes over the first identifier from the virtual volume to another primary volume provided by the destination primary storage apparatus, after completion of copy of data from primary volume of the source primary storage apparatus into primary volume of the destination primary storage apparatus and secondary volume of the destination secondary storage apparatus.
