"NVMe or Non-Volatile Memory Express is a new protocol that allows servers to talk to storage devices like solid-state disks. Within a server, NVMe SSDs connect to the PCIe bus using a range of different form factors. Across a storage network, NVMe-enabled devices communicate to a server using NVMe over Fabrics, or NVMe-oF.
We can compare NVMe to historical SAS, SCSI and SATA storage protocols. Within a server, these solutions required a controller that can be implemented directly on the motherboard or through an add-in card. Across the network, Fibre Channel and iSCSI allow a server to communicate to shared storage. This aligns with the capabilities of NVMe-oF..."
