Abstract:
Technologies for applying a redundancy encoding scheme to segmented portions of a data block include an endpoint computing device communicatively coupled to a destination computing device. The endpoint computing device is configured to divide a block of data into a plurality of data segments as a function of a transmit window size and a redundancy encoding scheme, and generate redundant data usable to reconstruct each of the plurality of data segments. The endpoint computing device is additionally configured to format a series of network packets that each includes a data segment of the plurality of data segments and generated redundant data for at least one other data segment of the plurality of data segments. Further, the endpoint computing device is configured to transport each of the series of network packets to a destination computing device. Other embodiments are described herein.
Abstract:
Methods and apparatus to recover a processor state during a system failure or security event are disclosed. An example apparatus to recover data includes a processor including a local memory and a system monitor in communication with the processor. The system monitor is to copy processor backup data to a non-volatile memory in response to a processor backup event. The processor backup data includes contents of the local memory.
Abstract:
Examples may include techniques to enable synchronized execution of a command by nodes in a network fabric. A node capable of hosting a fabric manager for the network fabric (fabric manager node) may generate one or more packets including a command to be executed by at least some nodes in the network fabric. In some examples, a time stamp is also included with at least one of the one or more packets to indicate to receiving nodes to execute the command at a synchronized time.
Abstract:
Technologies for reordering network packets on egress include a network interface controller (NIC) configured to associate a received network packet with a descriptor, generate a sequence identifier for the received network packet, and insert the generated sequence identifier into the associated descriptor. The NIC is further configured to determine whether the received network packet is to be transmitted from a compute device associated with the NIC to another compute device and insert, in response to a determination that the received network packet is to be transmitted to the another compute device, the descriptor into a transmission queue of descriptors. Additionally, the NIC is configured to transmit the network packet based on position of the descriptor in the transmission queue of descriptors based on the generated sequence identifier. Other embodiments are described herein.
Abstract:
Technologies for providing adaptive polling of packet queues include a compute device. The compute device includes a network interface controller and a compute engine that includes a set of cores and a memory that includes a queue to store packets received by the network interface controller. The compute engine is configured to determine a predicted time period for the queue to receive packets without overflowing, execute, during the time period and with a core that is assigned to periodically poll the queue for packets, a workload, and poll, with the assigned core, the queue to remove the packets from the queue. Other embodiments are also described and claimed.
Abstract:
Methods and apparatus for implementing Power over Ethernet (PoE) for auxiliary power in computer systems. Under aspects of the methods, one or more voltage inputs comprising standard power input is employed by a power control component in a network interface in an apparatus such as a network adaptor board, a System on a Chip (SoC), computer server or server blade to supply power to a network controller on the apparatus when the apparatus is operating at a normal power state. To enable the apparatus to maintain network communication when operating at a reduced power state, a PoE power input derived from at least one PoE signal received at at least one Ethernet jack of the apparatus is employed to provide power to the network controller absent use or availability of the standard power input. Accordingly, the PoE power input facilitates an auxiliary power function that may be used alone or in combination with existing (as applicable) auxiliary power input when apparatus are operated in reduced power states.
Abstract:
Embodiments of the disclosure are directed to controlling an endpoint device running an endpoint device using a central control server. The central controller server is configured to communicate with the endpoint device across a communications interface compliant with a remote direct access (RDMA) compliant protocol. The central control server includes an RDMA network interface controller and a control process. The control process can execute an endpoint device algorithm to identify read and write commands to be sent across the RDMA protocol-compliant interface to the endpoint device. The RDMA network interface controller can convert messages into RDMA compliant messages that include direct read or write commands and memory location information. The endpoint device can also include a network interface controller that can understand the RDMA message, identify the memory location from the message, and execute the direct read or write access command.
Abstract:
One embodiment provides a network adapter. The network adapter includes a network adapter controller, a medium access controller (MAC) and a physical layer (PHY) including at least one port. The network adapter further includes optical communication logic to at least one of receive and/or acquire a local alert and generate a local alert message related to the local alert, the local alert message including an alert identifier (ID) and a network adapter ID. The network adapter further includes a first light emitting diode (LED) to convert the local alert message to a corresponding optical local alert message and to transmit the optical local alert message to an optical communication path.
Abstract:
Network interface devices with remote storage control. In some embodiments, a network interface device may include receiver circuitry and remote storage device control circuitry. The remote storage device control circuitry may be coupled to the receiver circuitry and may share a physical support with the receiver circuitry. The remote storage device control circuitry may be configured to control writing of data from the receiver circuitry to a remote storage device that does not share a physical support with the remote storage device control circuitry.
Abstract:
Examples may include techniques to provide redundant array of independent disks (RAID) services using a shared pool of configurable computing resources. Information for a data service being provided using the shared pool of configurable computing resources may be received. Logical servers hosting logical volume managers (LVMs) may be composed from at least a portion of the shared pool of configurable computing resources. In some examples, the hosted LVMs are capable of each providing a RAID service based, at least in part, on the received information for the data service.
