    Abstract: PROBLEM TO BE SOLVED: To provide a computer system including a plurality of physical storage devices, wherein a storage device has a nonvolatile memory including bus numbering information of busses of the storage device itself and busses of one or more adjacent storage devices.
    SOLUTION: In a preferred implementation, all physical storage devices are provided with non-volatile memories including bus numbering information for their own busses and busses of both adjacent storage devices. This creates a distributed database of the interconnection topology for the computer system. Because storage devices contains bus numbering information about storage devices adjacent to them, bus numbers for busses in physical storage devices are made persistent across numerous different system reconfigurations. A preferred embodiment includes a bus number manager which reads the nonvolatile memories in the physical storage devices during initial program load (i.e., boot) and reconstructs the interconnection topology on the basis of information read from the nonvolatile memories and assigns bus numbers to busses in accordance with a derived interconnection topology.
