John Deere, in the 70s had two separate power companies provide their "non-interruptible power" for their mainframes, but the DP manager was not able to also add a diesel powered backup because the only vendor with the sufficient engine to meet their power needs used ONLY a Caterpillar diesel engine. After the fourth failure in a couple of years, the DP manager finally won approval from senior company management to install a diesel powered backup, but ONLY because it was housed in a lockee Deere-shed so no one would see there was a Yellow diesel engine inside.

Sure, what are the odds of a power failure requiring an enterprise-wide IPL *and* missing your one and only IODF file? Anyone? Dr. Murphy? Anyone? . .

For me it's a matter of training & expertise, but ...WHY STANDALONE? We talk about single file, IODF. Very important during IPL, but quite inactive during normal system run (with exception to HCD activities including ACTIVATE processing). Can you enlight us and tell us the prospect of such failure?
