    Abstract: Distributed storage systems, devices, and associated methods of data replication are disclosed herein. In one embodiment, a server in a distributed storage system is configured to write, with an RDMA enabled NIC, a block of data from a memory of the server to a memory at another server via an RDMA network. Upon completion of writing the block of data to the another server, the server can also send metadata representing a memory location and a data size of the written block of data in the memory of the another server via the RDMA network. The sent metadata is to be written into a memory location containing data representing a memory descriptor that is a part of a data structure representing a pre-posted work request configured to write a copy of the block of data from the another server to an additional server via the RDMA network.

    Abstract: Distributed computing systems, devices, and associated methods of virtual RDMA switching are disclosed herein. In one embodiment, a method includes intercepting a command from an application in a container to establish an RDMA connection with a remote container on a virtual network. In response to the intercepted command, an RDMA endpoint at a physical NIC of a server is created. The method can also include intercepting another command to pair with a remote RDMA endpoint corresponding to the remote container. The intercepted another command contains data representing a routable network address of the remote RDMA endpoint in the RDMA computer network. Then, the RDMA endpoint created at the physical NIC of the server can be paired with the remote RDMA endpoint using the routable network address of the remote RDMA endpoint.

    Abstract: Systems, methods, and computer-executable instructions for emulating a network are disclosed. A network topology and an indication of devices to emulate are received. A safe static boundary within the network that comprises each device in the indication of devices to emulate is determined. The safe static boundary is based upon the network topology. For each device to emulate, a unified container and a device container are instantiated. An emulated device is based on the unified container and the device container. Data links between the emulated devices are created based upon the network topology. An emulated network is created using the emulated devices.
