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.

It is provided a management computer which refers to switching level information including switching patterns to be used at a time of switching the first task to the second application server; sets a level of a degree of safety for each of the switching patterns; refers to a stop time for each first task which is allowed upon switching the first task to the second application server; selects one of the switching patterns having a switching time that is shorter than the stop time of the task requirement information which is set to the first task and having the level of the degree of safety that is highest among the switching patterns of the switching level information; stops the second task of the second application server by the selected one of the switching patterns; and then controls the second application server to provide the first task.

Occupancy amount of physical resource of a virtual server (VS) is calculated based on maximum physical resource amount indicating performance of a physical server (PS), the occupied virtual resource coefficient indicating relation of physical resource amount used by the VS to the physical resource amount allocated to the VS and the allocated physical resource coefficient indicating relation of the allocated physical resource to the maximum physical resource amount of the PS, and change value of the occupied physical resource amount from a predetermined occupied physical resource amount is calculated based on the calculated occupancy amount and the predetermined occupied physical resource amount. The migration time required of the VS is calculated based on the calculated change value, variation ratio indicating degree of influence exerted by change of the occupied virtual resource coefficient of the VS on the required migration time and reference execution time set based on the predetermined occupied physical resource amount.

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.

High availability computer system and fault correction method. If a fault occurs in the current-system physical device allocated to the current-system virtual device of the virtual server, the virtualization mechanism of the physical server configures, for the standby-system virtual device of the virtual server, the standby-system physical device, as a physical device which is used at a high priority, and the virtualization mechanism distributes the request issued from the standby-system virtual device of another virtual server to a standby-system physical device, but, when such a standby-system physical device does not exist, the virtualization mechanism distributes the request to a standby-system physical device configured for high priority usage.

Occupancy amount of physical resource of a virtual server(VS) is calculated based on maximum physical resource amount indicating performance of a physical server(PS), the occupied virtual resource coefficient indicating relation of physical resource amount used by the VS to the physical resource amount allocated to the VS and the allocated physical resource coefficient indicating relation of the allocated physical resource to the maximum physical resource amount of the PS, and change value of the occupied physical resource amount from a predetermined occupied physical resource amount is calculated based on the calculated occupancy amount and the predetermined occupied physical resource amount. The migration time required of the VS is calculated based on the calculated change value, variation ratio indicating degree of influence exerted by change of the occupied virtual resource coefficient of the VS on the required migration time and reference execution time set based on the predetermined occupied physical resource amount.
