With Ceph you have to install an orchestrator 3rd party in order to

Which can be ok, but not alway pheasable.
Just as with everything
As said wikipedia, for instance, "Proxmox VE supports local storage
with LVM group, directory and ZFS, as well as network storage types
with iSCSI, Fibre Channel, NFS, GlusterFS, CEPH and DRBD.[14]"
Maybe fibre channel shall provides a webinterface. Maybe iSCSI shall
too. Maybe drbd & glusterfs will provides another one.
Well, you are mixing different technologies:
1) ISCSI and FibreChannel are*networks comunication protocols*.
They just allow hypervisor to communicate to a SAN/NAS, they itself
doesn't provide any kind of storage.
2) ZFS, glusterFS, NFS are "network ready" filesystem not a software
deined SAN/NAS.
3) Ceph, ScaleIO, FreeNAS, HP virtualstore... they all are *Software
Defined *storage.
This means that they setup disks, filesystems and network connections in
order to be ready to use from client.
They can be thinked as a "storage kind of orchestrator" by theirself.
So only the group 3 is comparable technology.
In this competition I think that Ceph is the only one can win in the
long run.
It's open, it works, it's easy, it's free, it's improving faster than
others.
However, right now, it is the only one that miss a decent management
dashboard.
This is to me so incomprehensible. Ceph is by far a killer app of the
market.
So why just don't kill its latest barriers and get a mass adoption?
Or maybe this is not their job.
As you said, "Xen is just an hypervisor", thus you are using
bare-metal low level tool, just like sane folks would use qemu. And
yes, low-level tools are .. low level.
XenServer is an hypervisor but it has a truly great management dashboard
which is XenCenter.
I guess VMware has it's own and i guess also that it's good.
