Abstract

A blade management server is provided for managing the allocation of blade PCs to remote operating terminals, respectively. The blade management server responds to a request for alternative from the remote operating terminal to search for any one of the blade PCs that is not allocated yet, and notify the remote operating terminal of the address of the found blade PC. The remote operating terminal, when receiving the address, changes the blade PC to be connected to itself from the current “statically allocated” blade PC to the blade PC of the address notified of from the blade management server (the “alternatively allocated” blade PC).

said operating terminal further comprises a disconnection request portion that transmits said diagnosis request to said management server, acquires the operation status from said management server, and transmits said return request to said management server if the operation status of a predetermined one of said information processors indicates “

available”

or transmits said disconnection request to said management server if the operation status of said predetermined information processor indicates “

failed”

.

said information processor further includes an uploading portion that responds to said save request to add said user ID contained in said save request to the information stored in its information processor, and transmits it to said save server, and

said save server has a user information storage that stores the information received from said information processor in association with said user ID added to said information.

5. The information processing system according to claim 4, wherein

said management server further has a transfer commanding portion that responds to a reflection request containing said user ID and the designation of said currently connected information processor to transmit a transfer command containing said user ID to said information processor,

said information processor further includes a downloading portion that responds to said transfer command to transmit a transmission request containing said user ID that said transfer command contains to said save server and receive said information from said save server, and

said save server further includes a user information transmitter that responds to said transmission request to transmit to said transmission request source said information stored in said user information storage in association with said user ID contained in said transmission request.

6. The information processing system according to claim 1, further comprising a save server connected to said network, wherein

said management server further includes a remote copying portion that responds to a return request containing said user ID and the designation of a currently connected information processor to read out the information stored in said information processor designated by said return request from said information processor and cause said save server to store said read information in association with said user ID specified by said return request.

7. The information processing system according to claim 1, further comprising a save server connected to said network, wherein
