Abstract: Devices unnecessary for deployment are invalidated during the deployment. A method of building a system and a management server for establishing a system according to the present invention have the following configuration. The management server obtains server information from a server connected through a network, refers to the obtained server information to select devices unnecessary for deployment among devices connected to the server, and invalidates the selected devices.

Abstract: Provided is a deployment method for a server system that includes a storage system having logical disks where disk images are stored and plural servers connected to the storage system via a storage network, the method including the step of causing a deploy management module to copy the logical disks which store the disk images to a free area of the storage system before a deployment command is received. According to this invention, disk images are quickly deployed to servers.

Abstract: With a program deployment apparatus that is connected via a network to at least one physical server including a physical server with a virtualization facility for providing a virtual server to a client and deploys a program to the at least one physical server as necessary, and by a program deployment method for such a program deployment apparatus for deploying a program to the at least one physical server as necessary, one or more nodes which are connected via the network and are any of the physical server, the virtualization facility, and the virtual server are detected, first configuration information about a virtual layer of each detected node is acquired for each detected node, and the program is selectively deployed to the relevant node based on the first configuration information for each acquired node.

Abstract: A client side physical computer into which the job is loaded issues a job execution request to a server side physical computer. The job execution request is accompanied by job execution statements and environment information. A management and control module on the server side starts an OS for a logical computer and exercises control to assign a server side volume corresponding to a client side volume and transfer the data on the client side volume to the server side volume. A server side job management module for the logical computer converts the original job execution statements and environment information to match the computer environment for the logical computer, and executes the requested job.

Abstract: There is disclosed a high speed switching method for a disk image delivery system fail-over. A management server sends a disk image of an active server in advance to a standby server. When receiving a report that the active server has failed, the management server judges whether or not it is possible for the standby server to perform the service of the failed active server based on service provision management server information held by the management server and if possible, instructs the standby server to perform the service of the active server. Even if the disk image delivered in advance is different from the disk image of the failed active server, switching of is the service to the standby server can be performed more quickly through resetting the setting values of unique information and installing the additional pieces of software on the standby server by the management server than redelivering an appropriate disk image.

Abstract: A resource distribution method capable of lending surplus resources among a plurality of services and reducing the maintenance cost of the surplus resources is provided. Computer resources in the standby system have a dead standby state in which at least an application is not installed. A plurality of services or a plurality of users share the computer resources in the standby system. As a result, improvement of the utilization factor of idle computer resources and server integration are implemented, and the cost required to maintain the computer resources is reduced. Furthermore, load prediction is conducted as regards individual services by using past operation history. Idle computer resources secured from services having surplus and maintained are thrown in according to a result of the prediction.

Abstract: Provided is a computer system, including: at least one storage system providing at least one logical volume, at least one host computer including an I/O device, and a management computer, in which the management computer creates a virtual computer within a network segment to which the management computer belongs, the virtual computer including an I/O device that is the same as the I/O device of the host computer in number and type, defines a connection between the logical volume and the virtual computer, stores a program in the logical volume connected to the virtual computer, sets identification information on the host computer in the virtual computer, releases the connection between the logical volume that stores the program and the virtual computer, and defines a connection between the logical volume whose connection has been released and the host computer.

Abstract: A data sharing method and disk control device are ideal for running applications to process large amounts of data on remote computers in the same manner as in a database system. A disk control device contains a management table for showing the relation between a remote access identifier, a remote disk control device identifier, and command transfer control information for the remote disk control device to the disk identifier used by the host device, When a write command to write data on a designated disk is received from the host computer, the disc controller executes both a write process for writing data on a designated disk and a command transfer process for transferring a write command to the remote disk controller in accordance with command transfer control information in the management table.

Abstract: Disclosed is a A data sharing method and disk control device are ideal for running applications to process large amounts of data on remote computers in the same manner as in a database system. A disk control device contains a management table for showing the relation between a remote access identifier, a remote disk control device identifier, and command transfer control information for the remote disk control device to the disk identifier used by the host device. When; and when a write command to write data on a designated disk is received from the host computer, the disc controller executes both of a write process for writing the data on the a designated disk and a command transfer process for transferring the a write command to the remote disk controller in accordance with the command transfer control information shown on in the management table.
