The time (response time) from the issue of a display request for the
display of constructional information to the obtaining of predetermined
desirable constructional information and the completion of display is
long when a terminal device having (a graphical user interface) to manage
and control the operation of a storage system by using a storage managing
server is used. To reduce response time, the storage managing server
receives a first request issued from a storage managing terminal for
executing the processing of the storage managing server, and a second
request for executing processing including the communication of
constructional information of a storage device between the storage device
and the storage managing server. The storage managing server starts
processing with respect to the second request before the storage managing
server transmits a response to the first request to the storage managing
terminal.
