摘要： In a case where a failure has occurred in one of fabric management mechanisms (Ia, Ib), nodes (3, 4) resume data I/O communications without degrading performance and without changing the data I/O communication path between the nodes by switching control communication path to the other one of the fabric management mechanisms (Ia, Ib). The fabric management mechanisms (Ia, Ib) share management information with each other over inter-switch link (54). When a failure occurs in either of the fabric management mechanisms (Ia, Ib), an E_Node that belongs to the domain in which a failure has occurred, logs into the other one of the fabric management mechanism via a newly created control communication path. The other one of the fabric management mechanism allocates an N_Port_ID on the basis of a virtual FC domain number that has been allocated to a switch.

摘要： A cluster storage system is provided in which logical units are formed astride a plurality of storage devices. An administrator instructs creation of a volume to a virtual storage device and registration of a host port for providing access permission to the volume. The virtual storage device searches a candidate of a physical storage device capable of reaching the host port and a candidate of the target port based on the access permission information, and creates a distributed volume astride the candidate physical storage device. The distributed volume is composed of a plurality of partial volumes, and the partial volumes inherit the functions of the storage device and the access permission information set for the distributed volume. The virtual storage device distributes an access permission to the physical storage device, constitutes the access permission information of the host port and the volume with respect to the candidate target port, and registers the access permission information of the host port and the target port to the SAN switch. An IO request from the host is issued to an appropriate associated physical storage device based on the information associating the target port and segments of the partial volume, and load distribution of the storage functions and the IO request is performed in the physical storage device.

摘要： Systems and methods described herein involve a virtual storage utilized to virtualize the storage of storage systems across multiple sites. The virtual storage is associated with a virtual multipath control. The virtual multipath control manages the virtual path state of the inter-physical storage, the remote copy volume state which has primary volume or secondary volume state, and the volume copy operation mode such as synchronous copy mode journal copy mode, or bitmap resync mode. The virtual multipath control of the virtual storage facilitates choices from the host for a preferred site, path, state, and volume by utilizing a virtual multipath state from a get virtual multipath information command.

摘要： A system for cache promotion comprises: a server which includes a nonvolatile persistent memory having a cache data area that has a plurality of cache segments, and a server processor managing cache directory information which indicates whether each of the cache segments is valid or not, wherein a cache segment is valid when the cache segment is allocated for caching data; and a storage which includes a storage memory storing backup information of the cache directory information, a plurality of storage devices, and a storage processor configuring one or more logical units by storage space of the plurality of storage devices. When the server recovers from being down, the server processor is configured to obtain the backup information of the cache directory information from the storage, and, when the backup information indicates that a particular cache segment is invalid, to invalidate the particular cache segment in the cache directory information.

摘要： Data migration can be preformed between source and target storage subsystems without stopping exchanging data between a host computer and each of the storage subsystems. After a next access path, which should be set instead of a specific access path in an available state among access paths, is set between the host computer and a migration target logical unit via a host port and a target port, the status of the next access path is set to an available state and the status of the specific access path is set to an unavailable state. After the next access path is set to an available state, data is migrated from a migration source logical unit of the source storage subsystem to the migration target logical unit of the target storage subsystem.

摘要： A host computer is coupled to a first fabric, a source storage apparatus is coupled to a second fabric, and a destination storage apparatus is coupled to a third fabric. A destination port of the destination storage apparatus comprises a same WWPN as a WWPN of a source port, and is logged in to the fabric beforehand. Duplicate WWPNs are allowed to exist because an inter fabric router separately manages the second fabric and the third fabric. When a switchover is instructed, the inter fabric router switches a coupling destination of the host computer to the destination storage apparatus.

摘要： A cluster storage system is provided in which logical units are formed astride a plurality of storage systems. A virtual LU astride a plurality of storage devices is a virtual volume composed of a plurality of partial volumes. Functions of the storage system, Zoning information of a SAN and a host group information of the virtual volume are inherited to a partial volume created for each physical device. When a page granularity data migration is executed, volume or data are migrated to other storage devices without depending on the relationship between a physical port and the physical device. When a host IO request is received when migration is on-going, response processing is performed by synchronizing storage devices within the range of migration data. The host IO request related to the page being migrated sends a partial complete response including information for re-routing the request to a path of the appropriate data migration destination device capable of issuing the IO. A multipath software of the host splits the IO request into multiple requests based on the re-routing information included in the partial complete response, respectively re-selects the issue destination, and reissues the IO request to an appropriate storage system.
