I have a Ceph Reef cluster with 10 hosts with 16 nvme slots but only half occupied with 15TB (2400 KIOPS) drives. 80 drives in total. I want to add another 80 to fully populate the slots. The question: What would be the downside if I expand the cluster with 80 x 30TB (3300 KIOPS) drives?
How are the nodes' network interfaces loaded today? Can they sustain adding 200% of the current NVMe bandwidth?
