Data Center Rebuild

Decommission of a pair of 6509's. The environment was broken up to Nexus 7004's for the cores, Catalyst 3750's for the end user edge, and Nexus 5k/2k for the server edge. (update 1/2/2019) Answering some of my most common critiques up front: · "That's not a data center" - Not all data centers look like they're in a co-lo space. That room contains all the servers, networking, and other essential gear necessary to run the organization. Because of the equipment it housed we called it the data center. · "The job isn't finished" - I agree. Unfortunately my career took me elsewhere before I could make more progress. · "You should have done X instead of Y" - Possibly. The goal of the project was to decommission the old equipment and bring in new equipment. My approach was to bring in different equipment that allowed the environment to be managed more naturally through shorter cables. I'm certain there are some other critiques. I'll update this over time.
