Abstract: A physical layer transceiver (PHY) ability configuration system includes a peer computing device having a first communication subsystem that includes a first PHY device coupled to a first port. They system also includes a networking device having a second communication subsystem that includes a second PHY device and that is configured to operate in a plurality of modes and a second port that is coupled to the second PHY device. The networking device determines, in response to a cable coupling the first port and the second port while the second PHY device is configured to operate in a first mode of the plurality of modes, that a link is not detected at the second port. The networking device changes the first mode to a second mode of the plurality of modes, and detects the establishment of the link between the first port and the second port.

Abstract: A storage subsystem backplane management system includes a storage controller and a service processor. A first backplane including a first management controller is coupled to the storage controller and the service processor. The first backplane is operable to couple a plurality of first drives to the first management controller. A second backplane including a second management controller is coupled to the first management controller. The second backplane is operable to couple a plurality of second drives to the second management controller. The first management controller communicates with the second management controller and creates a virtual management controller that presents to the storage controller and the service processor a virtual backplane including the plurality of first drives and the plurality of second drives when the plurality of first drives are coupled to the first management controller and the plurality of second drives are coupled to the second management controller.
