Would it help if I partitioned the computing resources of my physical
machines into VMs?  For example, I put four VMs on each of three virtual
machines, each with a dedicated 2TB drive.  I can now have four tokens in
the ring and a RF of 3.  And of course, I can arrange them into a way that
makes the most sense.  Is this getting any better, or am I missing the
point?
