HPe Synergy low latency tuning

I was wondering whether the recommended settings found on page 10 in this technical white paper from HPe also makes very much sense for a Ceph cluster too.

Apart from the obvious hardware design, is there anything you definitively look for when building a Ceph cluster?

I'd be most likely going for an HPe Synergy 12000 frame which has dual 25/50Gbit links to each compute module (Ceph node) provided you use the 6820C 25/50Gb Converged Network
