Abstract
Abstract An interface in a data-processing system for identifying operating parameters of storage systems and enclosures is disclosed. The data-processing system communicates with the storage systems utilizing a serial bus. The storage systems are included within a storage system enclosure which includes a backplane. A backplane interface is included within the backplane and is utilized for coupling a storage system to the storage system enclosure. The storage system has a first and a second connector which are coupled together. The second connector is coupled to the backplane interface and is utilized to transmit data to be stored to and read from the storage system. A plurality of resistors are coupled to the first connector. A physical location is selected for a storage system by connecting selected ones of the resistors to a first potential, while all remaining resistors are connected to a second potential.
