NVMe over TCP (nicknamed "iNVMe") is the up-and-coming RDMA-free protocol for NVMe over Fabrics. Like iSCSI, NVMe over TCP offers commodity connectivity to storage arrays that get reliable, high performance connectivity via Fibre Channel.
If you’re in the storage business you realize that NVMe is the next big transformation coming. This technology promises ultra-fast applications due to a significant decrease in data access latency versus HDDs (and even today’s SSDs!). NVMe will be like switching on “ludicrous-speed” for these leading-edge applications,
