摘要： Examples are disclosed for access to a storage device maintained at a server. In some examples, a network input/output device coupled to the server may allocate, in a memory of the server, a buffer, a doorbell, and a queue pair accessible to a client remote to the server. For these examples, the network input/output device may assign an Non-Volatile Memory Express (NVMe) namespace context to the client. For these examples, indications of the allocated buffer, doorbell, queue pair, and namespace context may be transmitted to the client. Other examples are described and claimed.

摘要： Technologies for providing efficient detection of idle poll loops include a compute device. The compute device has a compute engine that includes a plurality of cores and a memory. The compute engine is to determine a ratio of unsuccessful operations to successful operations over a predefined time period of a core of the plurality cores that is assigned to continually poll, within the predefined time period, a memory address for a change in status and determine whether the determined ratio satisfies a reference ratio of unsuccessful operations to successful operations. The reference ratio is indicative of a change in the operation of the assigned core. The compute engine is further to selectively increase or decrease a power usage of the assigned core as a function of whether the determined ratio satisfies the reference ratio. Other embodiments are also described and claimed.

摘要： The present disclosure is directed to a unified device interface for a multi-bus system. In at least one embodiment, a system may comprise more than one data bus. Each data bus may be to convey data between an operating system (OS) and at least one device in the system, wherein a plurality of driver instances may facilitate interaction between the OS and a device via one or more of the data buses. In one embodiment, a main driver instance may be determined from the plurality of driver instances to present the device to the OS and coordinate operation of other driver instances. The other driver instances may map addresses in the memory of processing entities corresponding to each of the data buses and report these mappings to the main driver instance. Alternatively, a supervisory driver may be loaded to present the device and to control operation of the driver instances.

摘要： Examples are disclosed for forwarding or receiving data segments associated with a large data packets. In some examples, a large data packet may be segmented into a number of data segments having separate headers that include identifiers to associate the data segments with the large data packet. The data segments with separate headers may then be forwarded from a network node via a communication channel. In other examples, the data segments with separate headers may be received at another network node and then recombined to form the large data packet at the other network node. Other examples are described and claimed.

摘要： Examples include client access to a storage medium coupled with a server. A network input/output device for the server receives a remote direct memory access (RDMA) command including a steering tag (S-Tag) from a client remote to the server. For these examples, the network input/output device forwards the RDMA command to a Non-Volatile Memory Express (NVMe) controller and access is provided to a storage medium based on an allocation scheme that assigned the S-Tag to the storage medium. In some other examples, an NVMe controller generates a memory mapping of one or more storage devices controlled by the NVMe controller to addresses for a base address register (BAR) on a Peripheral Component Interconnect Express (PCIe) bus. PCIe memory access commands received by the NVMe controller are translated based on the memory mapping to provide access to the storage device.

摘要： Examples are disclosed for use of vendor defined messages to execute a command to access a storage device maintained at a server. In some examples, a network input/output device coupled to the server may receive the command from a client remote to the server for the client to access the storage device. For these examples, elements or components of the network input/output device may be capable of forwarding the command either directly to a Non-Volatile Memory Express (NVMe) controller that controls the storage device or to a manageability module coupled between the network input/out device and the NVMe controller. Vendor specific information may be forwarded with the command and used by either the NVMe controller or the manageability module to facilitate execution of the command. Other examples are described and claimed.

摘要： Methods and apparatus for implementing flow control with reduced buffer usage for network devices. In response to detection of flow control events, transmission of a data unit or segment such as an Ethernet frame is preempted in favor of a flow control message, resulting in aborting transmission of the frame. Data corresponding to the entirety of the frame is buffered at the transmitting station until the frame has been transmitted (or after a delay), enabling retransmission of the aborted frame. Preemption of frames in favor of flow control messages results in earlier responses to flow control events, enabling the size of buffers to be reduced.
