    摘要: A storage system configured to provide a storage area to a host coupled to the storage system includes a first storage device of first type being configured to store data and provide one or more data-storage-related functions. A second storage device of second type is configured to store data and provide one or more data-storage-related functions. A virtual volume provides a storage location and being associated with at least one of the first and second storage devices. A database includes information relating to the one or more data-storage-related functions that the first and second storage devices are configured to perform. A first server is coupled to the first and second storage devices and having access to the database, the first server being configured to access the database in response to a data-storage-related-function request from the host involving at least one of the first and second storage devices. The database is accessed to determine whether or not the at least one of the first and second storage devices is capable of performing the request from the host. The first server further being configured to perform the request if the determination is negative or provide an instruction to the at least one of the first and second storage devices to perform to the request if the determination is positive.

    摘要: A SAN manager acquires configuration information from devices constituting a SAN and produces a corresponding relationship between a host computer and a virtual volume (virtual volume mapping) and a corresponding relationship between the host computer and a real volume (real volume mapping). Based on those pieces of mapping information, the SAN manager outputs a corresponding relationship between virtual and real volumes. Meanwhile, the failure notification messages received from the in-SAN devices are construed to detect and output an influence of the failure upon the access to a real or virtual volume. Furthermore, when receiving a plurality of failure notifications from the devices connected to the SAN, the plurality of failure notifications are outputted with an association based on the corresponding relationship between real and virtual volumes.

    摘要: A remote copy network realizes low-cost multi-hop remote copying. Remote copying is executed via a remote copy network (RCN) having a source edge device connected to a source storage and a target edge device connected to a target storage. Because the RCN is a network provided by a network business, a user having a storage device can execute remote copying without owning or managing the RCN. The source edge device receives remote copy I/O from the source storage, creates a log entry to which a sequential number is added, and sends the log entry to a target edge device. The target edge device acquires the remote copy I/O from the received log entry, and sends the remote copy I/O to the target storage in the order of the sequential number.
