Hi, My understanding is that primary storage in CloudStack mainly depends mostly on what the hypervisor supports, and not CloudStack itself.
The table here in the official CloudStack documentation that shows the supported storage types per hypervisor, including FC for most of them: https://docs.cloudstack.apache.org/en/4.22.0.0/conceptsandterminology/choosing_deployment_architecture.html<https://docs.cloudstack.apache.org/en/4.22.0.0/conceptsandterminology/choosing_deployment_architecture.html> Another helpful link: https://www.shapeblue.com/cloudstack-storage-support/ I’m not a storage expert, but from a cursory look, FC should work fine as long as your hypervisor supports it. Hope that helps.

Having some FibreChannel stuff in the lab this could work well. ... but I am concerned that this is not the direction CloudStack is developing into. So: - NFS - iSCSI - Ceph ... would be the choices regarding the docs. Not sure if iSCSI would fit for shared storage as I do not see it in the list of protocols supported for primary storage in GUI. What is the most future-proof solution to choose for primary storage? I want to stay on the main-path CloudStack is going to, so I can use new features coming out in the next months and not being blocked by 'sorry, not supported for your protocol'
