What is NVME Over Fabrics (NVME-oF)?
Enterprise Storage Forum, Friday, June 16,2023
NVMe over Fabrics (NVMe-oF) is an approach to storage networking that uses the non-volatile memory express standard to provide high-speed data transfers across entire local area networks.
It's particularly well-suited for data center environments, because the messaging model of network communication it uses allows it to transmit data quickly over longer distances. This guide explains NVMe-oF and the networking protocols it uses as well as its major benefits and weaknesses.
What is NVMe over Fabrics?
NVMe is a storage and transfer specification designed for solid state drives that dramatically speeds up data access and response times. It works by accessing flash storage through a Peripheral Component Interconnect express (PCIe) bus, which supports up to 64,000 command queues instead of the single command queue supported by traditional mechanical disks and all flash SSDs.
