we are in the process of selecting hardware for a cluster. We are wondering
about RAM requirements. We found
http://docs.ceph.com/docs/jewel/start/hardware-recommendations/#ram, but we
are wondering:

1. Is up to date? Are these numbers valid for Luminous?
2. How valid is it for large disks, e.g. how much RAM does 1 OSD daemon
need for an 8+TB hard drive?

Thanks a lot!
