A disk storage system containing a storage device having a record medium for
holding
the data, a plurality of storage sub-systems having a controller for controlling
the storage device, a first interface node coupled to a computer using the data
stored in the storage sub-systems, a plurality of second interface nodes connected
to the storage sub-systems, a switch connecting to a first interface node and a
plurality of second interface nodes to perform frame transfer therebetween based
on node address information added to the frame. The first interface node has a
configuration table to store structural information for the memory storage system
and in response to the frame sent from the computer, analyzes the applicable frame,
converts information relating to the transfer destination of that frame based on
structural information held in the configuration table, and transfers that frame
to the switch.
