“Why open source? Ceph is literally the only things worth it for OS, but you need the expertise for it. If you don’t have that or the time/people to learn then go something else. We had just over 600TB usage and flipped to VAST and been very happy, now sitting at 3PB”

“With openstack? Obviously ceph , but also linstor alot lately. In large environments there is no (cost effective) alternative to ceph”

“I use Truenas for all my storage, and the block storage that I settled with is Cinder with NVME over TCP. Been running this for 2 months without issues. Knock on wood. This is a homelab.”

“Ceph is the storage that Red Hat (the largest contributor to the OpenStack project) recommends and uses for OpenStack. Most commercial OpenStack production deployments I've seen use Ceph.”
