Well its time to re-do the "core" of our network so this should be fun if not incredibly difficult and a tremendous amount of work.
I'll start out by saying the campus is a typical core-distribution-access model with about 290 servers all connected to the "core". The core consists of two cisco 6509 switches loaded up with 10/100 blades and 1000-Base GBIC based blades. Core's main funtion is server connectivity, data center routing, multicast routing/control and providing connectivity to all other buildings/distrubtion closets.
So rather than impossibly trying to upgrade these boxes with new supervisors, cards, etc I'm getting two other 6509s and loading them up with sup720 and dCEF 10/100/1000 blades. Figured now cisco has a real data center solution for 1000-Base-T (finally). These two switches will be the "server module" and will connect all servers. They'll also route and will be a fully redundant configuration with all the bells and whistles.
The old "core" will remain just that and get new horse power via sup720s and dCEF cards. Its new function will be that of L3 routing as fast as it can - connecting the distribution switches and other modules of the network like the security module (firewalls, dmzs, intrusion detection, etc)
Lots of work but maybe this thread can be a project long journal. If you have any ideas please let me know.
