摘要： A method is provided with which a name of a virtual port is not changed when virtualized storage is moved among switches. Information about a creator and a borrower of name information is added to a table including name information and address information of a virtual port of a name server managing the name information and the address information. The name information is provided to plural switches and managed. In addition, name information, which can be used commonly among name servers managing the name information and the address information is pooled in advance, and the name information of the virtual port is borrowed from there.

摘要： In a storage device having redundant input/output paths, both a transmission data amount and a reception data amount are smoothed among paths. A storage device predicts not only a transmission data amount to be formed by an output request in a transmission queue but also a reception data amount to be formed by an input request in the transmission queue. The storage device stores a newly occurred output request in a queue having a minimum predicted transmission data amount and stores a newly occurred input request in a queue having a minimum predicted reception data amount. In a storage device having redundant input/output paths, transmission data amounts and reception data amounts can be smoothed among the paths.

摘要： A storage device and method for ensuring the provision of data as complete files in a storage device capable of processing both block input/output I/O and file I/O. For each logical volume, an attempt is made to unmount logical units (LUs) storing files triggered by a session start request for block I/O (login request) such as iSCSI, and to recognize (mount) files of logical units triggered by a session completion request for block I/O (Logout request). Block access processing units may also create a replication of a specified logical unit and set a relevant replicated logical unit as a logical unit for access.

摘要： A computer subsystem is provided with a switch apparatus group that is at least one switch apparatus that is coupled to the communication network and a plurality of communication apparatuses that includes an internal management apparatus (an internal apparatus). The internal management apparatus transmits a request of a plurality of IP addresses that are allocated to the plurality of communication apparatuses to an external management apparatus that is disposed outside the computer subsystem. The external management apparatus manages whether or not each of M static IP addresses can be allocated, specifies a plurality of static IP addresses that can be allocated in response to the request, and transmits the plurality of specified static IP addresses to the internal management apparatus. The internal management apparatus allocates the plurality of static IP addresses to a plurality of internal apparatus.

摘要： In a storage system performing remote copy, when a failure occurs in a storage apparatus, optimum redundancy configuration is reestablished promptly. In the storage system performing remote copy, when a storage apparatus detects a failure in its disk drive, a storage apparatus capable of providing a logical unit that can be a replacement for the logical unit affected by the failure in the disk drive is searched for based on storage apparatus performance, and a redundancy configuration is reestablished using a new logical unit the found storage apparatus provides.

摘要： A port assignment device capable of properly distributing loads on each of a plurality of ports is provided. The device assigning a plurality of ports, storing data from external devices via a network in a plurality of storage modules and managing the data in the storage modules by a plurality of targets processing initiator commands from the external devices, to the targets includes a load information storage module which stores load information indicating a load on each port assigned to each of the targets and a processing module which alters the port assignment to each target so as to disperse the load on each port based on the load information stored in the load information storage module. It then becomes possible to control amounts of data to be transmitted or received, that is, to properly distribute such amounts of data.
