A Rat’s Nest of Cables
A CIO attended a demonstration of web server appliances that were new at the time. He was attracted by the blue lights, but he realized that the move to centralize thousands of servers would be a big migration project. More than 3,000 web servers would be affected, along with all the attendant networking.
When we started clearing the data center out, we had to remove five separate kinds of network equipment: Ethernet, Token Ring, ISDN, HIPPI, and SPI. What made this even worse was that generations of animals had made their homes in that equipment—so we were pulling out dead animals all the way through. Whenever someone complains to me about a rat’s nest of cables, I always think of that project.
On top of all the networking changes, we also found that we couldn’t fit the uninterrupted power supplies (UPSs) into each rack to support the web server appliances.
