About 8 years ago I was working at [name withheld]. Their main database was on a Sun 6500. We had mirrored data storage arrays, each with two power supplies/plugs, both running hardware RAID.
Unfortunately, the 6500 had only ONE power plug. Anybody care to guess which plug, out of seven, got unlocked and pulled?
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
