Disclosed herein are two-wire communication systems and applications thereof. In some embodiments, a slave node transceiver for low latency communication may include upstream transceiver circuitry to receive a first signal transmitted over a two-wire bus from an upstream device and to provide a second signal over the two-wire bus to the upstream device; downstream transceiver circuitry to provide a third signal downstream over the two-wire bus toward a downstream device and to receive a fourth signal over the two-wire bus from the downstream device; and clock circuitry to generate a clock signal at the slave node transceiver based on a preamble of a synchronization control frame in the first signal, wherein timing of the receipt and provision of signals over the two-wire bus by the node transceiver is based on the clock signal.

Virtual machines in a computer system cluster, or cloud environment, require access to their assigned storage resources connected to the virtual machines via storage area networks (SAN). Such virtual machines may be independent from associated physical servers in the computer system cluster on which they are deployed. These virtual machines may dynamically migrate among assigned physical servers while maintaining access to their connected storage resources both from the source physical server and the target physical server during the migration.

A method of a storage area network (SAN) includes storing and communicating data received from a server at a host bus adapter via a bus controller of the adapter. In a case where the data is associated with an address corresponding to a default boot logical unit (LUN) of a non-volatile memory (NVM) of the adapter, the data is stored in the NVM. In a case where the data is not associated with an address corresponding to a boot LUN of the NVM, the data is communicated over the SAN. During power up of the adapter, in a case where it is determined that the NVM includes an image of an operating system, the adapter uses the bus controller to provide the server with information to select the NVM as a boot LUN for booting the operating system.

An apparatus, system, and method are disclosed for managing a non-volatile storage medium. A storage controller receives a message that identifies data that no longer needs to be retained on the non-volatile storage medium. The data may be identified using a logical identifier. The message may comprise a hint, directive, or other indication that the data has been erased and/or deleted. In response to the message, the storage controller records an indication that the contents of a physical storage location and/or physical address associated with the logical identifier do not need to be preserved on the non-volatile storage medium.

Methods and apparatus for virtual channel allocation within an electronic device. In one exemplary embodiment, the device is a consumer electronics device having multiple camera sensors uses a modified high-speed protocol (e.g., DisplayPort Multi-Stream Transport (MST) protocol) to process camera data via one or more virtual channels. Unlike traditional solutions which rely on an intelligent source device to manage a network of devices, the present disclosure describes in one aspect a network of nodes internal to a consumer electronic device that is managed by the sink node (i.e., a smart sink). Additionally, since the full suite of protocol (e.g., DisplayPort) capabilities are unnecessary for certain design scenarios, certain further disclosed simplifications improve performance for sink nodes having very modest capabilities.

Systems and methods for managing a production server using a storage array. In an illustrative, non-limiting embodiment, a storage array may include a memory coupled to a processor, the memory having program instructions configured to cause and/or enable the storage array to: receive hardware information from a multipath input/output (MPIO) module of each of a plurality of production servers in communication with the storage array; provide the hardware information to a management server in communication with the storage array; receive a command from the management server targeting a selected production server; and transmit the command to a selected MPIO module of the selected production server.

To accommodate multiple masters over bus architectures supporting a single master device, a mechanism is provided for an inactive master device to assert an in-band IRQ. A current master then polls the other inactive master devices over a shared data bus to ascertain which inactive master device is asserting the IRQ. Upon identifying the asserting inactive master device, the current master device grants control of the data bus to the new master device, thereby making the inactive master the new active master device.

Methods, non-transitory computer readable media, and storage management computing devices that obtains and stores a plurality of LUN ranges and an indication of a plurality of ports of a bridge device corresponding to the plurality of LUN ranges. A LUN is received from the bridge device. One of the plurality of ports of the bridge device to which a storage device associated with the received LUN is attached via inclusion in one of a plurality of stacks communicably coupled to the one of the plurality of ports of the bridge device is identified. The received LUN is within one of the plurality of LUN ranges corresponding to the one of the plurality of ports. An action is initiated based on the identified one of the plurality of ports of the bridge.

The invention relates to a method for managing configuration of an industrial internet field broadband bus, the method being applicable to a two-wire data transfer network in which a bus controller and respective bus terminals are synchronized in clock, and the bus controller allocates time slices for the respective bus terminals and the bus controller, so that the bus controller firstly acquires the configuration information, and determines the bus terminal corresponding to the configuration information, and then the bus controller transmits the configuration information to the bus terminal in the time slice occupied by the bus controller, when the bus controller need transmit configuration information to the respective bus terminals, to thereby make the bus terminal perform corresponding configuration operations according to the configuration information.
