CISCO is holding an all day Virtual Summit January 21st. You can learn more and preregister for the event at the main site: http://www.brighttalk.com/summit/datacenter3
Here at Novant, we have been really focusing on moving to a converged networking and storage solution, since VMworld 2009 last year. CISCO has a powerful solution in their new Unified Computing System. We also have been heavily involved looking at a solution from xSigo. With the new Fault Tolerance feature in vSphere 4 pushing the NIC requirements to 8 to 10 or more NICs (especially if your using ISCSI), converged fabric just makes sense.
I would also point you to the following link for an intersting perspective on the CISCO solution:
