Re: suggestions re. cluster configuration

Also you don't need heartbeat in OpenSSI.  If you want active/active
cluster without external storage OpenSSI+DRBD is the way to go versus
just DRBD+heartbeat.  I wouldn't imagine too many people doing
active/active setups using DRBD without OpenSSI.  CFS failover is much
more elegant.  Plus if CPU is the bottleneck in your application you
can always add more nodes to your OpenSSI+DRBD cluster.
