Yup.  I have 4 gigE ports on each box - so I was thinking 2 for storage, 
2 for outside - giving me full redundancy (I have two separate outside 
connections for the cluster).

Not really.  I have a mix of production email/listserv/web/database on 
one VM (relatively low load), a backup server on a second VM, and the 
rest of the cluster is used for a mix of development and test for some 
new service development.  Short term, load will be low, but could start 
spiking quickly.  My other task is designing for rapid expansion - first 
through AWS, then through more hardware.

Thanks Again,

Miles
