摘要:
A computer system includes a switch having a plurality of ports, a plurality of devices coupled to the plurality of ports, and a management system coupled to at least one of the plurality of devices and the switch. The coupling between the plurality of devices and the switch is a communication interface in which the number of master devices capable of existing in the same space is defined. The management system collects device coupling data of each of the plurality of devices coupled to the switch. Each of the device coupling data includes an ID of a port to which the device is coupled and information representing an attribute indicating whether the device is a master or a slave. The management system determines a coupling configuration on the basis of the plurality of the collected device coupling data and a communication interface protocol and, configures, to the switch, coupling information that is information in accordance with the determined coupling configuration.

The first application program and/or the second application program send(s) an access request to the second cache management module. The second cache management module receives the access request from the first application program and/or the second application program, and references the second cache management table to identify the storage location of the access-target data conforming to the access request. When access-target data exists in first cache area, the second cache management module sends a data transfer request to the first cache management module storing the access-target data, and where access-target data does not exist in the first cache area, acquires the access-target data from the second storage device. When the access-target data is in first cache area, the first cache management module acquires the access-target data conforming to the data transfer request from the relevant first cache area, and sends access-target data to the second cache management module.

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 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.

Servers and a management server for managing a computer resource for a providing application constructed from storage connected to the servers receive an identifier of the application and a requested resource amount to assign to the application, refer to a application profile to identify the application and a system image corresponding to the identifier, and on the basis of the identifier, refer to a application usage history database and a application data table to acquire the number of times that the application has been used and the existence or non-existence of saved application data. If the usage is a reuse and there is saved application data, storage in which the application data has been saved is acquired from the application data table, and a combination of a server and storage which satisfies the requested resource amount and can access the application data is determined by referring to a resource table.

In a computer system in which a server has, in addition to a disk used for booting, an operation transfer destination disk that has the same content as the boot disk, a method for changing the disk used by the server or another server in the computer system for booting to the operation transfer destination disk is realized by changing the content of the operation transfer destination disk to enable the OS and applications installed in the operation transfer destination disk to be booted from the destination disk and by changing the setting of a boot program of the server to enable booting from the operation transfer destination disk.

A power consumption controller controls the power consumption of a physical server having a virtual server. A management server determines an unused CPU budget from the difference between the total amount of the loads of respective virtual servers and a hypervisor and the total CPU budget of the physical server. The management server determines the drive frequency of the CPU inside the physical server based on the unused CPU budget. The management server changes a CPU allocation budget related to the respective virtual servers and the hypervisor in accordance with the determined drive frequency. The hypervisor controls the CPU allocation budget and drive frequency in accordance with an indication from the management server.Accordingly, the power consumption of the physical server is controlled.
摘要:
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.

A proposed fail over method for taking over task that is preformed on an active server to a backup server, even when the active server and the backup server have different hardware configuration. The method for making a backup server take over task when a fault occurs on a active server, comprises steps of acquiring configuration information on the hardware in the active server and the backup server, acquiring information relating the hardware in the backup server with the hardware in the active server, selecting a backup server to take over the task that is executed on the active server where the fault occurred, creating logical partitions on the selected backup server, and taking over the task executed on the active server logical partitions, in the logical partitions created on the selected backup server.

In a network computer system, recovery may be impossible from a fault when the fault occurs in a network switch in a network or a device such as an external disk device. Provided is a computer system that includes a plurality of servers, a plurality of network, a plurality of external disk devices, and a management computer, in which the management computer detects a fault which is occurred, retrieves an application stop server inaccessible to the used disk due to the fault, retrieves the disk for storing the same contents as contents stored in the disk used by the retrieved application stop server and the external disk device including the disk, retrieves an application resuming server capable of accessing the retrieved external disk device, and transmits an instruction to boot by using the retrieved disk to the retrieved application resuming server.
摘要:
In a computer system wherein plural servers are connected with an external disk device via a network, each server incorporates therein a logic partition module for configuring at least one logic partition in the server, and the operating system stored in the logic partition is booted by the boot disk of an external disk device, the failover operation is performed only for the logic partition affected by a failure when the task being executed by a working server is taken over by another server at the time of the failure occurring in the working server.
