Abstract: Apparatus and methods are disclosed herein for remote, direct memory access (RDMA) technology that enables direct memory access from one host computer memory to another host computer memory over a physical or virtual computer network according to a number of different RDMA protocols. In one example, a method includes receiving remote direct memory access (RDMA) packets via a network adapter, deriving a protocol index identifying an RDMA protocol used to encode data for an RDMA transaction associated with the RDMA packets, applying the protocol index to a generate RDMA commands from header information in at least one of the received RDMA packets, and performing an RDMA operation using the RDMA commands.

Abstract: A technology is described for a device diagnosis station. The device diagnosis station may be configured to identify an electronic device physically connected to the device diagnosis station, evaluate an operational state of the electronic device by executing testing instructions configured to test the functionality of the electronic device and collect operational state information for the electronic device. The device diagnosis station may be configured to determine the operational state of the electronic device and execute recovery instructions to restore the electronic device to an improved state when a recoverable error is detected. The device diagnosis station may be configured to initiate a device return procedure for the electronic device when a non-recoverable error state is detected.

Abstract: A first write transaction is received by a device that includes a transaction identifier and a memory location identifier. The memory location identifies a register or a memory location of a device. A value from the register or memory location is read. A second write transaction is sent to a block of host memory. The second write transaction includes the value and the transaction identifier.

Abstract: Provided are systems and methods for reliable, out-of-order receipt of packets. In some implementations, provided is an apparatus configured to communicate with a network and a host device. The apparatus may receive packets over the network at a receive queue. The packets may originate from a source on the network, and may be received out of order. The apparatus may further, for each received packet, identify a transport context associated with the source and a destination of the packet, and determine whether the packet can be accepted. Upon determining that the packet can be accepted, the apparatus may further identify the one receive queue at which the packet was received; determine a user application to receive the packet, transfer the packet from the one receive queue to a buffer in host memory, and identify an order in which the packet was received with respect to other packets.

Abstract: A network device includes a processor coupled to network interface circuitry and cryptographic circuitry. The network interface circuitry is configured to couple the network device to a local computer communication network. The processor is configured to generate an encryption key based on a hardware specific value recorded in the network device, and apply the cryptographic circuitry and the encryption key to encrypt files for storage in an Internet storage system coupled to a remote computer communication network, and present the encrypted files stored, by the processor, in the Internet storage system, to a computing device coupled to the network device via the local computer communication network, as a storage system attached to the local computer communication network.

Abstract: Apparatus, methods, and computer-readable storage media are disclosed for core-to-core communication between physical and/or virtual processor cores. In some examples of the disclosed technology, application cores write notification data (e.g., to doorbell or PCI configuration memory space accesses via a memory interface), without synchronizing with the other application cores or the service cores. In one examples of the disclosed technology, a message selection circuit is configured to, serialize data from the plurality of user cores by: receiving data from a user core, selecting one of the service cores to send the data based on a memory location addressed by the sending user core, and sending the received data to a respective message buffer dedicated to the selected service core.

Abstract: A network device stores information associated with a packet in a queue. The network device sends an interrupt to a host to notify the host of completion of processing the packet. A Memory-Mapped Input/Output (MMIO) write transaction is received that includes a pointer update associated with the queue and an interrupt unmasking value. The pointer is updated and the interrupt is unmasked based on receiving the single MMIO write transaction.
