I'd seen/helped build/benchmarked some very nice/fast CephFS based
storage systems in $dayjob-1. While it is a neat system, if you are
focused on availability, scalability, and performance, its pretty hard
to beat BeeGFS. We'd ($dayjob-1) deployed several very large/fast file
systems with it on our spinning rust, SSD, and NVMe units.
