What does your internal network look like for ceph?
40 ssds as my osds... 5 hosts... all nodes are all functions (monitor/manager/metadataservers), if I added more servers I would not add any more of those... (which I do have 3 more servers for "parts"/spares... but could turn them on too if I really wanted to.
2x 40gbps networking for each server.
Since upstream internet is only 8gbps I let some vms use that bandwidth too... but that doesn't eat into enough to starve Ceph at all. There's 2x1gbps for all the normal internet facing services (which also acts as an innate rate limiter for those services).
