Future is bright for NVMe-over-Fabrics with TCP and Ethernet, say Solarflare, Lightbits
https://www.theregister.co.uk/2018/07/26/tcp_nvme_over_fabrics_ethernet/
Lightbits Labs and Solarflare are promoting the idea of NVMe-over-Fabrics (NVMe-oF) using TCP-over-bog-standard Ethernet, instead of RDMA over Converged Ethernet (RoCE) via data centre-class Ethernet, iWARP, InfiniBand or Fibre Channel.
Solarflare claims NVMe-over-TCP using Ethernet provides IT departments with the same high bandwidth, low latency performance as iWARP and RoCE, and it'll work with 90 per cent of the 100 million Ethernet ports shipped into their data centers each year.
