The hope is to be able to provide scale-out storage, that will be performant
enough to use as a primary fs-based data store for research data (right now we
mount via NFS on our cluster nodes, may do that with Ceph or perhaps do native
cephfs access from the cluster nodes.) Right now I’m still

bottleneck. Some

Hi all,
Kind of new to Ceph (have been using 10.2.11 on a 3-node Proxmox 4.x cluster
[hyperconverged], works great!) and now I'm thinking of perhaps using it for a
bigger data storage project at work, a PoC at first, but built as correctly as
possible for performance and availability. I have
