Q: What are the upstream/downstream services? What feeds/services do the systems host?
If you have a lot of feeds coming in and out of each of the application systems, then that will have a requirement in terms of the SAN storage and the network capacity you're going to be putting through these systems. How do these hang off -- do you need dial-up modems, ISDN connections, FTP, secure file transfer? How do you employ and support those configurations within a virtual infrastructure?
