There are a large number of operation workload reallocating plans, but in terms of a required calculation resource, it is undesirable to, in each case, derive power consumption required for a cooling apparatus, select and control operation workload deployment for minimizing a total value of the derived power consumption and server power. The present invention derives a rule about the IT workload allocation in advance from configuration information (static information) including position information of facilities including an air conditioner of the data center and the IT equipment items, changes priority of an applied rule on the basis of dynamic information including ambient temperature, and changes the IT workload allocation, thereby reducing the power consumption of the air conditioner.

Management computer, computer system including the same, and method for providing allocating plan for it equipment

An air conditioner that cools inside a room wherein a plurality of server apparatuses is arranged, is driven with high efficiency. An information apparatus is communicatively coupled to a plurality of server apparatuses each capable of implementing a virtual server, stores a relation between a cooling performance and a cooling efficiency of an air conditioner that cools a room wherein the server apparatuses are arranged stores a history of load on each of the server apparatuses, the load being generated by a virtual server implemented in the server apparatus, creates a plurality of virtual server allocation patterns having varying allocations of virtual servers to be implemented by the server apparatuses, simulates, for each of the created allocation patterns, an amount of heat generation of each of the server apparatuses on the basis of the history of load on the server apparatus, seeks a cooling performance required to be offered by the air conditioner on a basis of the simulated amount of heat generation, and identifies the allocation pattern with which the cooling efficiency corresponding to the sought cooling performance is not less than a threshold set in advance.

Information apparatus and method of optimizing cooling efficiency of air conditioner

A sort server including a central processing unit, a memory and a network interface configured to interconnect the sort server with a search server, at least one storage system and multiple processing servers using at least one network. The sort server is configured to receive a search result from the search server and to assign multiple tasks to the processing servers. The assignment of the multiple tasks is based on a condition including the search result. Assignment of the tasks to servers may be based on CPU load of at least some of the multiple servers, network architecture, network distance between the servers and the storage system storing the required object, failure information, urgency of the task, Level Agreement associated with the servers and other tasks performed by the servers.

Method and apparatus for unstructured data mining and distributed processing

The invention enables the control of the information in a storage unit in a user terminal, prevents data from leaking to unauthorized users and protects information in the user terminal. A management OS manages the input/output to/from a user work OS in the user terminal, identifies a control-triggering condition set by a management server, controls the information in the storage unit storing the user work OS-related information so that information leakage can be prevented, and it also backs up the user work OS-related information to the storage apparatus using the user work OS input/output information.

Storage unit information control system for user terminal

In a remote desktop system, information pertaining to client resources is included in screen information that a server manages to display in a client. In the remote desktop system, the client collects information pertaining to units making up the client or to programs as resource information, and sends the collected information to the server via a network. The server manages the resource information obtained from the client, and creates screen information to be displayed in the client. In the creation of the screen information, the server creates client screen information (first screen) including the resource information of the server within the screen information of the client, or creates server screen information (second screen) including the resource information of the client within the screen information of the server, and displays the first or second screen in the client.
