[HECnet] Galaxy questions

Any galaxy experts out there? This concept is totally new to me, but it looks like my ES40 can be configured as a galaxy (it probably was - there's 2 of everything in there). I'd like to experiment with setting it up (why? Because it's there). Do I install a separate copy of VMS in each side? Do I configure the two galaxy members to also be a cluster? Thoughts and discussion are appreciated (remember, there's nothing 'practical' about any of this - I'm just interested in playing with all of the architectures) Also, what license do I need for galaxy?
