Do we have any limit on the nodes here?

What limits are you thinking about? I am not aware of anything specific at the moment.

i dont know, like we have limit for number of snapshots on an image for mapping the node. If we dont have any limits in gateway itself we are good

@Madhu-1 HI, there is a limitation (in GW) of the number of namespaces (=rbd image) can subsystem handle.

The `ceph-nvmeof` project provides a NVMe-oF Gateway that makes RBD-images available over the NVMe-oF TCP protocol. Ceph-CSI can use this to provision block-type volumes that are accessible over a standard protocol instead of depending on RADOS/RBD. Signed-off-by: Niels de Vos <[email protected]>
