摘要： A server management apparatus monitors activity state of an active server that provides a service to a client(s) via a plurality of switches, instructs a route control apparatus, managing routing for the plurality of switches, to change a packet forwarding route if there is no reply from the active server; and recognizes that the active server is stopped if there is no reply from the active server after a forwarding route is changed and instructs a standby server to provide the service instead of the active server.

摘要： A communication system includes a plurality of nodes and a control device. Each node includes a packet processor that processes a packet in accordance with a processing rule when the packet is received. The processing rule correlates the processing applied to the packet with a matching rule that identifies the packet the processing is to be applied to. The control device calculates a packet forwarding path in response to a request for setting processing rules from any node, sets processing rules that implement the packet forwarding path on the node on the packet forwarding path and records the processing rules in a manner coordinated with one another. The control device inquires at the node on the packet forwarding path about state of setting of processing rule and, upon detecting failure in the processing rule set in at least one node, executes rollback operation on the correlated processing rules set in other node.

摘要： A computer system of the present invention is provided with an open flow controller 3, and a switch 4i. The switch 4i notifies a MAC address contained in packet data to the open flow controller 3 when the packet data from the virtual machine that the migration has completed does not fit with a rule shown by the flow set to the switch itself. The open flow controller 3 sets a communication flow for a migration destination VM generated according to the notified MAC address to the switch 4i. The switch 4i transfers the packet data for said virtual machine which follows a rule 444 shown by the communication flow for said migration destination VM, to the migration destination virtual machine based on an action 445 shown by the communication flow for said migration destination VM.

摘要： Devices and interior equipments that need not operate in a server room are stopped and thereby power saving can be achieved. More specifically, consolidation of virtual machines (VMs) providing a service is performed to concentrate processing in a server in a certain rack among a group of racks in the server room, a rack having no operating server is stopped, processing by an interior equipment controlling the rack and its circumference environment also is stopped or adjusted, and thereby power saving can be achieved.

摘要： There is provided a distributed data storage system for splitting content-data into a plurality of split data and storing a plurality of copy data corresponding to at least one of the plurality of split data in a plurality of memory devices. The system comprises a copying management information storing unit and a access location determining unit. The copying management information storing unit stores copying management information indicating a storage location of the copy data corresponding to the split data. The access location determining unit determines at least one of the plurality of memory devices storing the copy data corresponding to the split data as an access location for accessing split data.
