How many proxmox nodes are you using in that setup? and how many storage nodes?

Ceph looks really interesting as far as I can tell. I did a small POC
with a few vm's and it seems to work well. It seems to scale really
well. We can also easily monitor it with prometheus.

We also requested an offer for a Dell Compellent iSCSI setup. Anyone
has any experience with these? What's your (horror-)story?
