NVME-oF Gateway Requirements
We recommend that you provision at least two NVMe/TCP gateways on different nodes to implement a highly-available Ceph NVMe/TCP solution.
We recommend at a minimum a single 10Gb Ethernet link in the Ceph public network for the gateway. For hardware recommendations, see hardware recommendations .
Note
On the NVMe-oF gateway, the memory footprint is a function of the number of mapped RBD images and can grow to be large. Plan memory requirements accordingly based on the number of RBD images to be mapped.
