Hi,
having a 3-node ceph cluster is the bare minimum you can have to make it wor=
king, unless you want to have just a replica-2 mode, which is not safe.
It's not true that ceph is not easy to configure, you might use very easily c=
eph-deploy, have puppet configuring it or even run it in containers. Using d=
ocker is in fact the easiest solution, it really requires 10 minutes to make=
a cluster up. I've tried it both with jewel (official containers) and krake=
n (custom containers), and it works pretty well.
The real problem is not creating and configuring a ceph cluster, but using i=
t from ovirt, as it requires cinder, i.e. a minimal setup of openstack. We h=
ave it and it's working pretty well, but it requires some work. For your ref=
erence we have cinder running on an ovirt VM using gluster.
Cheers,
Alessandro=20

I think Ceph requires a lot more resources than above. It's also a bit mor=
e
challenging to configure. I would highly recommend a 3-node cluster with G=
luster.
