John Deere's data center in the 70s had multiple AC providers but still had Midwest lightning induced outages, but the data center manager was unsuccessful in installing a diesel backup system because the only UPS system that met their power needs was available ONLY with a Caterpillar Diesel engine, and the board would not approve.
After the third or fourth outage, the data center manager was finally allowed to build a GREEN windowless building to house the diesel and generator, and they snuck the yellow Cat engine into its home in the middle of the night.

Sort dissing their own product. He blocked all efforts to install diesel generators. Thankfully he is long gone. A major multi-state event in the mid-2000s induced the company to finally invest in serious power backup and DR. I love the old saw about the cobbler's children going without shoes. . .

To test power redundancy, they occasionally drop one power feed or the other--with ample heads up--and check that all devices are functioning. Other than call-home events, we have not had any surprises so far. Testing for a full power outage (both sides) is a lot harder, but it has been done here a few times. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
