摘要： Technologies for flexible I/O protocol acceleration include a computing device (1602) having a root complex (1624), a smart endpoint (1632) coupled to the root complex (1624), and an offload complex (1634) coupled to the smart endpoint (1632). The smart endpoint (1632) receives an I/O transaction that originates from the root complex (1624) and parses the I/O transaction based on an I/O protocol and identifies an I/O command. The smart endpoint (1632) may parse the I/O transaction based on endpoint firmware that may be programmed by the computing device (1602). The smart endpoint (1632) accelerates the I/O command and provides a smart context to the offload complex (1634). The smart endpoint (1632) may copy the I/O command to memory of the smart endpoint (1632) or the offload complex (1634). The smart endpoint (1632) may identify protocol data based on the I/O command and copy the protocol data to the memory of the smart endpoint (1632) or the offload complex (1634). Other embodiments are described and claimed.

摘要： Technologies for flexible I/O endpoint acceleration include a computing device (1602) having a root complex (1624), a soft endpoint (1632) coupled to the root complex (1624), and an offload complex (1634) coupled to the soft endpoint (1632). The soft endpoint (1632) establishes an emulated endpoint hierarchy based on endpoint firmware. The computing device (1602) may program the endpoint firmware. The soft endpoint (1632) receives an I/O transaction that originates from the root complex (1624) and determines whether to process the I/O transaction. The soft endpoint (1632) may process the I/O transaction or forward the I/O transaction to the offload complex (1634). The soft endpoint (1632) may encapsulate the I/O transaction with metadata and forward the encapsulated transaction to the offload complex (1634). The soft endpoint (1632) may store responses from the offload complex (1634) in a history buffer and retrieve the responses in response to retried I/O transactions. The I/O transaction may be a PCI Express transaction layer packet. Other embodiments are described and claimed.

摘要： Technologies for load balancing a storage network include a system. The system includes circuitry to adjust routing rules in a network interface controller to deliver a packet from one of multiple uplinks to one of any physical functions, circuitry to remap, in response to a failure of a switch, a port from one physical function to another physical function, and circuitry to communicate control data between a software defined network controller and one or more agents in one or more host endpoints with a hierarchical distributed hashing table.
