Abstract: Non-volatile memory express (NVMe) is a data transfer protocol used to enable high-speed data transfer between a host computer system and a solid-state drive (SSD). NVMe may be implemented over network fabrics and referred to as NVMe over fabrics (NVMe-oF). Access to SSD storage over network fabrics via NVMe-oF allows software defined storage to scale to allow access to a number of NVMe devices and extend distances between devices within a datacenter over which NVMe devices may be accessed. A network device is provided to automatically detect, prioritize, and route NVMe network packets in a network that includes multiple data communication protocols. For example, the network device may obtain network packets, analyze network packets to identify packet type and protocol, and redirect the network packets based on the analysis and detection. Thus, a processing priority may be provided for NVMe packets to assist in lossless communication implementations for storage across a network.
