Non-Volatile Memory express (NVMe) is an interface standard and protocol for accessing SSDs over a system PCIe bus.
Non-Volatile Memory express over Fabrics (NVMe-oF) extends the benefits of NVMe over a network fabric into the data center.
Transmission Control Protocol (TCP) is the latest transport added to the family of existing NVMe transports; PCIe, RDMA, and FC.
NVMe/TCP allows a host DMA memory to access external flash storage using the PCIe bus protocol across TCP/IP links
