I don't have the decoder ring, but I've seen one on TV ;)
I thought VMware was basically three offerings with some supporting
software: Workstation, GSX/Server, ESX/Virtual Infrastructure. There is
a tool for doing physical to virtual migrations (P2V) called Converter
(mileage varies from what I've heard).
I think Workstation and Server are fairly similar except that
Workstation has support for lots of snapshots. Server is free and is
nice for trying out different linux distributions, doing tests of custom
linux loads, having a windows VM for doing support for family/friends
when you don't actually have any use for it otherwise, ...
The Virtual Infrastructure (formerly ESX) is the expensive stuff. If
you buy the vmotion add on, you can shuttle vm's from one Virtual
Infrastructure to another (all of the VMs live on a SAN).
