Dave Raffo, senior analyst at Evaluator Group, based in Boulder, Colo., said native TCP is the easiest method for deploying NVMe-oF since TCP is native to the box.
“You don’t need to make any hardware changes. You use the same Ethernet network for NVMe that you’re already using,” Raffo said.
Organizations could also deploy Fibre Channel, InfiniBand and Remote Direct Memory Access-enabled Ethernet as NVMe-oF. Unlike TCP, there are additional costs to consider when using these existing networks as an NVMe fabric. Fibre Channel and InfiniBand may require switching upgrades, while additional network interface cards are needed to support Ethernet-based NVMe-oF.
