Response to: Virtual testing
Virtual Servers eat up a lot of memory when you want to test three or four nodes.
Abundance of hardware includes RAM in a single box. If you have plenty of RAM in your desktop and you can afford to fire four virtual machines, good for you.
I have been using VMWare WS for 7 years. But when I need to do some heavy testing on replicating nodes, I prefer emulation over virtualization.
