"virtually no IOs came direct from or go directly to disk"
I sincerely hope, in case of power failure, that they have a very capable battery back-up system with proven failover and generators that kick in to immediately supplement the batteries because otherwise I think there'll be a hell of clean-up job when the power comes back on again.
I'm sure they have that in mind, though. Just wonder what the figures are on power consumption and time-to-shutdown in case of outage.
