Abstract
A data storage system includes storage array and a switch that is configurable to create numerous network topologies within the system and to maintain separate communications paths between different computerized devices or networks and the storage array. For example, a user device and a service device, such as a system diagnosis device, can connect to the storage array through the switch. In order to isolate interaction or communication between the user and service devices, the switch can be logically partitioned into two distinct switches to form two distinct, isolated communications paths between the devices and the storage array. With isolated communications pathways established in the switch, in use, the service device is unable to access the user device coupled to the storage array.
