Hello,
you should put your metadata on a fast (ssd/nvme) pool. The size depends on your data, but you can scale it anytime as you know it from Ceph itself. Maybe just start with 3 SSDs in 3 Servers and see how it goes.
For CPU / Ram it's a bit the same, you need a few gigs for smaller and maybe more for bigger deployments. Maybe you can provide some insights about your typical data (size, count,..) and don't forget, you can scale by adding additional online mds as well.

_______________________________________________Dear ceph users,
I would like to ask, does the metadata server needs much block devices for storage? Or does it only needs RAM? How could I calculate the amount of disks and/or memory needed?
Thank you very much
