Abstract: An operation management server that manages a storage apparatus in which volumes are included and data is sent and received via transmission resources is provided. The operation management server includes a setting unit that sets a target value of the performance to some or all of the volumes; a monitoring unit that monitors the load factor of the transmission resources; and a bandwidth management unit that specifies a target transmission resource on the basis of the load factor of the transmission resources, that decides, on the basis of the target value, bandwidth allocation of some of the volumes that use the specified transmission resource, and that instructs a bandwidth control unit in the storage apparatus to adjust the bandwidth on the basis of the decided bandwidth allocation.

Abstract: A network management apparatus includes a first storage unit, a second storage unit, and a controller. The first storage unit stores therein communication groups included in the same subnet and information about communication devices belonging to the respective communication groups in association with each other. The second storage unit stores therein for each of the communication devices a port of a relaying device connected to the communication device as a connection destination port. The controller allows the relaying devices to perform communication between the connection destination ports on the basis of the first storage unit and the second storage unit to allow communication only between the communication devices belonging to the same communication group.

Abstract: A managed server (srv-10) is powered on by a power controlling unit. The managed server executes a POST process, and transfers a PXE request to a boot controlling unit. The boot controlling unit transfers an HBA vendor determining program. In the managed server, the WWN is set by an HBA vendor-dedicated program corresponding to an HBA vendor, and when a PCI initialization code can not be loaded, the POST process is re-started, and the PXE request is transferred again. The boot controlling unit transfers an NOP program, and the managed server starts an OS with a SAN boot.

Abstract: Device component information (physical information, logical information) on each device such as a host computer, a switch, and storage on the SAN is acquired via an LAN 9. Element information is created from the acquired device component information. According to the element information, a link between element information is created. Furthermore, when a plurality of links are established for an element, information is stored in advance so as to be used for selecting one of the links. Thus, each element stored the minimum information for routing and it becomes possible to search an associated element more effectively.

Abstract: When a server RM detects a failure in an operating server, a system resource manager selects a substitute server from a pool of a server domain to which a failed server belongs, based on information in a system resource DB, disconnects the failed server from a business network and a storage sub group and moves the failed server to a pool, and permits the substitute server to access a storage group to which the failed server had an access and to connect to the business network to which the failed server was connected, to boot up the substitute server from a SAN.

Abstract: When information on a device such as a server, storage, and an FC switch constituting a SNA system is input, these devices are displayed and arranged properly on a screen (S1, S2). When information on a physical path is input by a designer by using this display screen, a virtual SAN system in which the devices are connected by a fiber channel is displayed on the screen (S3). Furthermore, when information on an access path is input by the designer by using the construction image, the access path is additionally displayed on the construction image of the virtual SAN system (S5). Since the construction image of the virtual SAN system is displayed on the screen, the designer can easily create a design drawing while visually checking the SAN system. This can reduce the work load and time required for construction of the SAN system.

Abstract: An input/output request sent from a host is once cued through a channel adapter and is then transferred to a resource manager and is cued, and the cuing is distributed. Even if sequential input/output requests of the host are separated through a distribution processing to a plurality of paths, they are recognized on the device controller side and a countermeasure is taken. In the case in which a path from the host to the device controller is caused to be redundant into an operation system and a standby system, a path confirmation command is issued to the device drivers of a standby system path in order to confirm that the standby system path is normally operated or not. When the issuance of the input/output request is transferred to another path, a command for releasing the reserve of a transfer path is issued from another path.

Abstract: According to the present invention, an input/output controller connected between an interface connection port of an information processing apparatus and a network device so as to connect the information processing apparatus and a network includes an identification number obtaining part obtaining an identification number unique to the network device, a port number obtaining part obtaining a port number from the interface connection port of the information processing apparatus, and an identification information generation part generating identification information on the network from the identification number and the port number.

An applied technique determination section then determines an applied technique for improving at least one of reliability and processing speed according to the logical volume requirement. A logical volume setting section then outputs instructions to generate a logical volume which is made up of a plurality of disk drives and which is used for realizing the determined applied technique and instructions to set an environment in which a server accesses the logical volume by using the applied technique to the server and a disk array.

Abstract: On the screen of a computer, a server, a storage device and an FC switch are virtually provided and these devices are connected by a physical path. When an instance is generated in the server and the instance is dragged/dropped into the storage device, both the command to establish a multipath and the command to acquire a data area corresponding to the instance in the storage device are automatically generated. These commands are transmitted to the respective devices of an actually configured storage system.

Abstract: An integrated management mechanism of a storage area network (SAN) integrates and manages a traditionally dispersed security system from a single source and automates security management in the SAN. The integrated management mechanism integrates and manages the SAN, and is configured so that access relationships of the host computers and the storage devices of the SAN are managed using the integrated management mechanism. An access path on the integrated management mechanism, including a region of the storage devices to which access is attempted from the host computer, the fiber channel adapters used when accessing that storage, and the host bus adapters (HBA) are configured. Based on the access path information configured, the integrated management mechanism establishes respective storage settings, zoning settings, and accessible region permissions for a SAN management mechanism of the host computer, a zoning settings mechanism of the switch, and a storage management mechanism of the storage device.
