Abstract: A network interface device executes an input/output (I/O) virtualization manager to identify a virtual device defined to include resources of a particular virtual functions in a plurality of virtual functions associated with a physical function of a device. An operation is identified to be performed between the virtual device and a system image hosted by a host system coupled to the network interface device. The network interface device emulates the virtual device in the operation using the I/O virtualization manager.

Abstract: Examples described herein relate to accessing an initiator as a Non-Volatile Memory Express (NMVe) device. In some examples, the initiator is configured with an address space, configured in kernel or user space, for access by a virtualized execution environment. In some examples, the initiator to copy one or more storage access commands from the virtualized execution environment into a queue for access by a remote direct memory access (RDMA) compatible network interface. In some examples, the network interface to provide Non-Volatile Memory Express over Fabrics (NVMe-oF) compatible commands based on the one or more storage access commands to a target storage device. In some examples, the initiator is created as a mediated device in kernel space or user space of a host system. In some examples, configuration of a physical storage pool address of the target storage device for access by the virtualized execution environment occurs by receipt of the physical storage pool address in a configuration command. In some examples, configuration of the target storage device for access by the virtualized execution environment occurs by receipt of a storage pool internal NVMe Qualified Name in the configuration command.

Abstract: Examples described herein relate to a reliable transport protocol for packet transmission using an Address Family of an eXpress Data Path (AF_XDP) queue framework, wherein the AF_XDP queue framework is to provide a queue for received packet receipt acknowledgements (ACKs). In some examples, an AF_XDP socket is to connect a service with a driver for the network device, one or more queues are associated with the AF_XDP socket, and at least one of the one or more queues comprises a waiting queue for received packet receipt ACKs. In some examples, at least one of the one or more queues is to identify one or more packets for which ACKs have been received. In some examples, the network device is to re-transmit a packet identified by a descriptor in the waiting queue based on non-receipt of an ACK associated with the packet from a receiver.

Abstract: Methods and apparatus for smart switch centered next generation cloud infrastructure architectures. Smart server switches are implemented in place of Top of Rack (ToR) switches and other switches in cloud infrastructure that include programmable switch chips (e.g., P4 switch chips) that are programmed via data plane runtime code executing on the switch chips to implement data plane operations in hardware in the switches. Meanwhile, control plane operations are implemented in the server switches via software executing on one or more CPUs or are implemented via servers that are coupled to the server switches. The data plane runtime code is used to forward data traffic and storage traffic in hardware via the programmable switch chips in a manner that offloads forwarding to hardware in virtualized cloud environments.
