Abstract: A server system has a blade system formed of a plurality of servers that are mounted in one or a plurality of stages within a single chassis so as to have a plurality of different functions, and a management server for managing said blade system. The management server has means for grouping the plurality of mounted servers to manage for each function, means for managing the deployment of the plurality of servers within the chassis, and deployment changing means for changing the functions of the plurality servers and transposing the functions to change the deployment of the servers within the chassis. Thus, the deployment changing means makes the servers of each of the plurality of functions be arrayed in regular order within the chassis.

Abstract: A switch control system including a storage unit, a switch which logically sets a network topology between the storage unit and a plurality of computers, and a management server which communicates with the switch and the storage unit, wherein the storage unit includes at least one disk; wherein the management server comprises a memory and a processor, wherein the memory holds the network topology which is set by the switch, wherein when a failure is detected in one of the computers currently being used, the processor of the management server refers to the memory to change the network topology for the computer where the failure is detected and another computer which substitutes the computer where the failure is detected, and instructs the switch with the changed network topology so as to cause the switch to logically set the changed network topology, and wherein the management server controls the disk of the computer where the failure is detected to be accessible.

Abstract: When a failure is detected in a server currently being used, a management server changes the network topology for the server currently being used and another server which substitutes the server. Then, the management server instructs the network SW with the changed network topology so as to cause the network SW to set the network topology logically. In addition, the management server instructs a disk array unit to control accesses from the other server to the disk in accordance with the server where the failure is detected.

Abstract: In a server system, functions of blade servers can be visually recognized at a glance. A change in load due to a failure can be detected to modify the system configuration by changing functions of blade servers. The server system includes a blade system including servers having different function types, the servers being installed in one or more stages in one enclosure, and a managing server for managing the blade system. The managing server includes a first managing section for classifying the servers into groups, a second managing section for managing a state of arrangement of the servers in the enclosure, and an arrangement changing section for changing functions of the servers discretely and for changing arrangement of the servers in the enclosure by replacing functions of the servers. The arrangement changing section arranges the servers in the enclosure on a function basis of the servers.
