<p>Systems and methods that allow a PSD (12) to be physically shared by multiple servers (20a, 20b, 20c) such that if a server fails, another server can be utilized as a backup server for the PSD without any manual intervention or moving of the PSD and without risking loss of data from the PSD. A PSD is interfaced by an interface device (16) to a system level bus (18) that allows for multiple initiators. An initiator is any server that can access and issue commands over the system level bus to access the PSD. When one of the servers fails, the functionality of the server can be rolled to a backup server which will be able to access the PSD over the bus.</p> |
