Not yet ... performance is still somewhat off where it needs to be to
replace Lustre. I do think this will be changing rapidly though.
CephFS is still in the not-quite-fully baked state, but it is evolving
We'd run some HPC type trading benchmarks on it 2 years ago
). Ping me offline if you want more info.
