| 20080209043 | SERVER MIGRATION PLANNING SYSTEM AND SERVER MIGRATION PLANNING METHOD - A server migration planning system for planning server migration from source servers to destination servers is provided. A processor allocates the respective source servers to any ones of the destination servers, based on the resource usage of the respective source servers and resource capacity of the respective destination servers. The processor selects the source servers one-by-one in descending order of the resource usage, selects any one of the destination servers, and makes a comparison between a comparison-object usage as the resource usage of the selected source server and a remaining amount of the resource capacity of the selected destination server. If the comparison-object usage is more than the remaining amount, the processor selects another destination server and then makes the comparison again. If the comparison-object usage is not more than the remaining amount, the processor allocates the selected source server to the selected destination server. | 08-28-2008 |
| 20100250734 | SERVER REASSIGNMENT SUPPORT SYSTEM AND SERVER REASSIGNMENT SUPPORT METHOD - A server reassignment support system has a storage device, a deallocated state estimation module and an allocation plan generation module. Stored in the storage device are an operation data indicating operation status of a plurality of physical servers and a plurality of virtual servers and a capacity data indicating resource capacity of each of the plurality of physical servers. The deallocated state estimation module refers to the operation data and the capacity data to extract an overloaded server from the plurality of physical servers, load of the overloaded server exceeding a threshold value depending on the resource capacity. Further, the deallocated state estimation module estimates a state in which at least part of virtual servers allocated to the overloaded server is deallocated as a deallocated server among the plurality of virtual servers. The allocation plan generation module generates an allocation plan for the deallocated server based on the estimated state. | 09-30-2010 |
| 20110022911 | SYSTEM PERFORMANCE TEST METHOD, PROGRAM AND APPARATUS - A system performance test method for testing performance of a server system includes: (A) a step of issuing a plurality of types of request sequences with a specified issuance ratio to the server system; and (B) a step of measuring performance of the server system during processing of the plurality of types of request sequences. Each of the plurality of types of request sequences is comprised of a sequence of requests to the server system. | 01-27-2011 |
