Abstract: Methods and structure for selectively powering a storage device over a data network. An exemplary system includes a power module configured to detect power from a host system via a network port. The system also includes an input/output controller configured to receive power derived from the network port of the power module, and in response, to identify a disk drive for a read/write operation based on information from the host system. With power derived from the network port, the power module is further configured to supply power to an expander that connects the disk drive to the input/output controller, and to supply power to the disk drive to perform the read/write operation.

Abstract: Methods and structure for powering storage devices over a SAS interface. An exemplary system includes a storage device that includes a receptacle configured to receive a plug that communicates Serial Attached Small Computer Systems Interface compliant signals from a host system. The storage device also includes a microcontroller configured to detect a first power level on a power contact of the receptacle. The storage device further includes a circuit board configured to power up to the first power level via the microcontroller, to receive an inter-integrated circuit communication that indicates a second power level is available, and to power up to the second power level to sufficiently power a storage appliance.

Abstract: A universal controller connector is modular, scalable and enables ease of connection between various storage devices (e.g., hard drives) and the same midplane controller. The universal controller connector solves the need for modularity and scalability for use with new storage controllers requiring midplane connections by managing connections between midplane controller and interface modules. The connection form factor enables universal connectivity of modules to a controller.
