running on it, it is a storage node, and of course, other OpenStack services can be run on that node.Cinder-volume is a storage node hat, CINDER-API is a control node hat. In our environment, devstack-controller wear both hats at the same time, so it is both a control node and a storage node. Of course, we can also use a dedicated node to run Cinder-volume.This
