The only thing missing making Proxmox difficult in traditional environment is a replacement for VMware's VMFS (cluster aware VM file system).

Lots and lots of organizations already have SAN/storage fabric networks presenting block storage over the network which was heavily used for VMware environments.

You could use NFS if your arrays support it, but MPIO block storage via iscsi is ubiquitous in my experience.

The Proxmox answer to this is Ceph - https://ceph.io/en/

And how does Ceph/RBD work over Fibre Channel SANs? (Speaking as someone who is running Proxmox-Ceph (and at another gig did OpenStack-Ceph).)

Not really, that works if you want to have converged storage in your hypervisors, but most large VMWare deployments I've seen use external storage from remote arrays.
