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: 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.

摘要: A virtualization switch virtualizes a data storage area provided by a server device and provides it to a server device with. This virtualization switch processes a priority control and a bandwidth control also on the output side to packets which make an access to a virtual volume and which have different demands for a QoS but identical IP headers according to a discrimination result of a TCP connection. Here, the TCP connection is discriminated by managing a TCP source port on the side of the virtualization switch.

摘要: To provide a technique whereby a value of an error recovery level determined in negotiation processing between an initiator and a target can be set to a suitable value that is intended by a manager. A storage system comprises a storage section containing a target module that is connected to an initiator device; and a management section that manages the storage section. The target module carries out negotiation processing with the initiator device so as to determine a value of a first error recovery level. The first error recovery level is determined as the smaller of a value of a second error recovery level of the initiator device and a value of a third error recovery level of the target module. The management section carries out setting processing for allocating the initiator device that is to be connected to the target module to the target module, according to an instruction from a manager. In the setting processing, the value of third error recovery level is notified to the manager.
