Abstract
A method and system for transferring NVMe data over a network comprises using a discrete buffer memory device to generate a write command from an NVMe-over-RDMA write command request, store the user data from a client host of the network, and send an interrupt signal to a NVMe storage device of the network. The NVMe storage device retrieves the write command from the discrete buffer memory device and performs a direct memory access transfer of the stored user data from the discrete buffer memory device to the NVMe storage device. The discrete buffer memory device comprises a controller and a random access memory for generating commands and storing the commands in a submission queue of the random access memory. The controller can clear commands from the submission queue based on completion commands received in a completion queue of the random access memory.
