Abstract: The system has switches permitting the storage device to be shared by two separate controllers. Each controller in turn recieves commands and transfers the stored data to a different data processing system. The arrangement involves a number of subchannels each of which comprises at least one addressable storage device and two addressable interlocked port switches. The subchannel switching arrangement is characterized by each switch being addressable as if it were another device.
