Does anyone have any experience with how BeeGFS compares to Lustre?
We're looking at both of those for our next generation HPC storage
system.
Is CephFS a valid option for HPC now? Last time I played with CephFS
it wasn't ready for prime time, but that was a few years ago.

Forgive me for saying this, but the philosophy for software
defined storage such as CEPH and Gluster is that forklift
style upgrades should not be necessary.
When a storage server is to be retired the data is copied onto
the new server then the old one taken out of service. Well,
copied is not the correct word, as there are erasure-coded
copies of the data. Rebalanced is probaby a better word.
This ^^
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.
