John Deere's data center in the 70's had two independent power supply companies, but with Midwest lightning strikes still had several to many outages each year.
Data Center Manager could NOT get approval for a diesel power backup UPS because: The only backup system that was large enough for their power load was available from a single vendor and that vendor would ONLY use a caterpillar diesel engine. I think after the second year of outages, the data center manager was finally allowed to build a John Deere Green colored outbuilding building to hide the yellow Caterpillar engine.
