To answer the great question, yes. SIOC is a datastore technology and works regardless of the number of hosts or clusters in the vSphere data center. If for some reason you had a noisy VM, SIOC would throttle the queue. You can test it out in the lab assuming you have a supported storage protocol.
Please note that SIOC is a datastore wide scheduler for multiple hosts. If a single host accesses a datastore then the local scheduler (SFQ) handles the scheduling per VM based on the assigned shares.
So if you have a lab with a single host and a couple of VMs then there is no real point in enable SIOC on that datastore.
