Storage controller and computer system for managing information related to connection port

摘要

In a computer system with at least one upper node (10,20) having connection ports (11,12,21), an information exchanger (30) and a storage controller (40), the storage controller has a control table (48) containing identification information for each connection port and related security information. An independent claim is also included for a storage controller which is connected to an information exchanger connected to a connection port included in an upper node device and which passes a packet via the information exchanger with the upper node.
