Ceph provides block storage while Gluster doesn't, but the latest it's 
far easier to setup. As block storage, Ceph is faster than Gluster, but 
I have all my proxmox virtual environment with gluster running perfectly.

On its day, I relied on Gluster because it was a more mature product 
than Ceph, ready for production, but now I'm toying in a second cluster 
with Ceph because now it's becoming a mature product as well... both 
have pros and cons, and both are good, so I think there isn't a "winner" 
between them at the moment.

Bonded interfaces on linux are active-backup, so you have a 1Gb 
connexion on the storage side. Consider to upgrade to a faster 

You will have no problems with your intel nuc as quorum node, I have a 
512MB RAM VM with 8GB HDD with debian and proxmox for that purpose.
