Do I need to have a separate server for cinder-volume if ceph is used? [closed]

The previous administrator has made several separate cinder-volume servers on VMs, but I don't understand why this is necessary, and I can't find information where someone could recommend doing this when only ceph is used. If I configure cinder-volume on the controllers, can it adversely affect performance of Cinder or controllers? I want to remove cinder-volume VMs, if they aren't needed.

Of course cinder-volume adds some load, so in principle it does affect the controllers' performance. Probably not in a measurable way though.

You don't need to run cinder-volume on separate servers or VMs when your only Cinder backend is Ceph.
