    Abstract: Provided is an information storage system including a first storage apparatus configured to provide a first logical volume, a second storage apparatus configured to provide a second logical volume, and a quorum accessed from the first storage apparatus and the second storage apparatus and including information regarding states of the first storage apparatus and the second storage apparatus. The second storage apparatus is configured to, after detecting communication failure with the quorum, halt use of the quorum and check communication with the first storage apparatus for failure before responding to the host for each of read and write commands sent from the host.

    Abstract: An example is a method of controlling a storage system for providing a virtual storage apparatus that includes virtual storage resources associated with real storage resources of real storage apparatus. It includes receiving a virtual storage resource control command of a predetermined type specifying a first virtual storage resource in the virtual storage apparatus and a second virtual storage resource associated with the first virtual storage resource; referring to management information for managing association relations between the virtual storage resources and the real storage resources, to identify a first real storage resource associated with the first virtual storage resource and a first real storage apparatus including the first real storage resource; and selecting a second real storage resource associated with the second virtual storage resource from real storage resources within the first real storage apparatus, or creating the second real storage resource within the first real storage apparatus.

    Abstract: An example of the present invention is a storage system comprising a first real storage apparatus including a plurality of real resources. The first real storage apparatus includes: real resource groups allocated to a plurality of virtual storage apparatuses; first management information for associating virtual resource identifiers individually assigned to real resources in a namespace independently defined for each of the plurality of virtual storage apparatuses with real resource identifiers individually assigned to the real resources in a namespace defined for the first real storage apparatus; and a controller for receiving a command including a designation with a virtual resource identifier, converting the virtual resource identifier in the command into a real resource identifier with reference to the first management information, and processing the command with the converted real resource identifier.

    Abstract: The present invention relates to executing data compression based on the used capacities of real pools. The present storage subsystem stores a definition information regarding conditions of starting data compression and ending data compression defined via usage rates of a real pool as physical area, wherein if the usage rate of the real pool satisfies the condition for starting compression, the compression processing is started, and if the usage rate satisfies the condition for ending compression, the compression processing is ended.

    Abstract: An exemplary storage system according to the invention includes a first physical storage apparatus providing a first real volume and a second physical storage apparatus providing a second real volume to form a copy pair with the first real volume. The first physical storage apparatus provides a first host with a first storage identifier and a first volume identifier for the first host to access the first real volume. The second physical storage apparatus provides a second host with at least a part of a first virtual storage apparatus including a first virtual volume allocated the second real volume. The second physical storage apparatus assigns the first volume identifier to the first virtual volume and the first storage identifier to the first virtual storage apparatus.
