In order to use VSM, you are required to build the Ceph cluster using VSM. VSM version 2.2.0 can control or manage the existing Ceph cluster (import the existing Ceph cluster). In this recipe, we will use Vagrant to launch four virtual machines named vsm-controller, vsm-node1, vsm-node2, and vsm-node3. The vsm-controller virtual machine will act as the VSM controller node and vsm-node1, vsm-node2, and vsm-node3 will act as VSM agent nodes running the Ceph cluster.
