Claim:
A blade server power control method in a system having a server composed of a plurality of blade servers, a client for operating the blade server, and a management server for managing the server, wherein said management server has information indicative of a correspondence relationship between a blade server user identifier for identifying a user who uses said blade server, and said blade server, wherein said client transmits a first power control request to said management server, said first power control request including a client user identifier for identifying a user who uses said client, and information for identifying said blade server, wherein said management server, upon receipt of the first power control request, determines from the information indicative of the correspondence relationship whether the blade server user identifier corresponding to the client user identifier corresponds to the information for identifying said blade server, wherein said management server transmits a second power control request to said blade server which is identified based on the information for identifying said blade server when said blade server user identifier corresponds to the information for identifying said blade server, wherein said blade server, upon receipt of the second power control request, controls its power based on the received second power control request, wherein said management server stores management information indicating whether any failure is detected or not in each of said blade servers, said management information being associated with the information for identifying said blade server, and wherein said management server does not transmit the second power control request to the identified blade server, when said management information indicates that a failure is detected in the identified blade server.
