Network Changes For Increased Performance

I have to say one of the things I really like to do is to take a network that is far behind in technology and bring it up to a better state.  I went in this past Friday to a customer and worked overnight to implement a new Brocade FCX with Advance code on it (as the new core switch) and to implement VLANs on it to try to separate traffic.  We also upgraded a few switches to Gig switches and changed some topology as well.  There were a few surprised along the way, which did slow things down quite a bit.  We didnt get to accomplish all the goals we wanted, so there will be a phase II to this project now.  But all in all, I do really enjoy taking a network from point A to point B to better the performance.  I guess that sounds nerdy, but I really enjoy it.
