We took on a pretty extensive list of tasks as part of this clean up, including replacing server older networking components with a single new Cisco ASA. While it's usually not recommended to make several logical and physical changes at the same time so you can avoid troubleshooting nightmares later, we were taking advantage of a planned power outage and wanted to accomplish as much as we can while we had everything turned off - including rebalancing all our servers on our power circuits, updating our UPS firmware and recabling every server and workstation port in the data center.
Here is shot of the same racks after the project was nearly complete. It's like night and day!
While it was a crazy weekend with our own version of a "spaghetti western", the end result was well worth it!
