Abstract: A system comprising a gateway at a premises and configured to communicate with a premises device including a proprietary communication protocol different from a protocol of the gateway. The system includes a bridge server coupled to the gateway and to a device server. The device server corresponds to the premises device. An integration component, running on the bridge server, corresponds to the premises device. The system includes a virtual instance running on the gateway. The virtual instance corresponds to the premises device. The virtual instance is configured to represent a state change of the premises device using data received from the premises device via at least one of the integration component and the device server.

Abstract: Apparatus for storing and retrieving data such as in a computer network. A plurality of local data storage units each comprise a local control circuit and a housing which encloses a moveable data transducer adjacent a data storage medium. A shared resource module physically interconnects each of the local units, and includes shared circuitry that supplies a resource required by the local control circuits to transfer data to and from the data storage media. In some preferred embodiments, the resource comprises a programming instruction set that is utilized by a programmable processor in each of the local control circuits, such as servo code used to provide data transducer positional control. Alternatively, the resource comprises a shared buffer memory space utilized by read/write channels in each of the local control circuits. Preferably, data are stored across the data storage media using RAID techniques (redundant array of independent discs/devices).

Abstract: A data storage array is provided such as for a distributed storage system or a consumer electronics device wherein increased data storage capacity is provided at the cost of increased power consumption in relation to industry standard power consumption rates. The array has a plurality of data storage devices, each having an actuator operably disposed in a data storing and retrieving relationship with a data storage medium. The data storage medium is rotated at a speed of substantially greater than 10,000 revolutions per minute, and each of the data storage mediums has a data storage capacity of substantially greater than 100 gigabytes. The increased heat created by the relatively faster rotation speed is handled through improved airflow made possible by a multiple disc array constructed in accordance with embodiments of the present invention.

Abstract: Disclosed is a storage system and method that provides multi-path bus and component interconnection and isolation in a data storage system. A plurality of data storage devices in a removable assembly are connected to a fabric that is configurable to connect some or all of the data storage devices to a disc controller and configurable to isolate one or more data storage devices from the disc controller. Multiple controllers, fabrics, and interconnecting buses may be employed to provide redundancy in the event of a connector, bus, or controller failure. Computer program code operating in a host, interface controller, and/or disc controller configures the fabric to isolate failed devices and may be employed to optimize data transfer rates. Data storage devices may be multi-ported. The fabric may comprise any device or devices capable of configurably interconnecting data storage devices to one or more controllers and may comprise multiplexers, cross point switches, port bypass controllers.

Abstract: Disclosed is a data storage architecture that provides data regeneration following the failure of two storage domains and that provides conversion for RAID-6 to RAID-5 or RAID-0 without moving or copying any data. A storage grid comprising at least eight domains and sixteen rows contains user data in a first contiguous portion and may contain row parity data in a second continuous portion and may contain vertical parity data in a third contiguous portion. In one embodiment data is arranged in row and vertical sets each comprising four data blocks such that each user data block is a member of one row set and is a member of one vertical set. In another embodiment sets comprise two blocks each.
