Thanks for posting this - was not aware of data center loss-of-power
failure. Seems as if data center had only (1) backup generator ?? I
worked for years as an engineer in both nuclear and fossil power
plants. We always had at least two lines of defense in any scenario
that would have tripped the plant off-line and created an outage
condition. Sure would like to learn what the power supply
configuration was for this data center.
Staller, Allan
of the outage.
Sounds to me like the ANZ exec that shot his mouth off got his foot
stuck in it.
It would not be in IBM's interest to upset said executive by revealing
his incompetence to all!

Sounds to me like maybe it wasn't accidental.

we did a lot of failure mode analysis for our ha/cmp product
http://www.garlic.com/~lynn/subtopic.html#hacmp
part of that included PDU (power distribution units ... for large
datacenters handled power switch-over from public power to various power
sources ... like battery pending diesel generator being brought online).
one corporate plant site had paid something like $5m for a diesel
generator power backup system. now places like hospitals have procedures
like running on emergency power at least an hour or two a month as part
of verifying that it actually works when needed. in the five yrs that
the diesel generator was in place ... nobody at the plant site ever
thought to periodic test it. so what do you think happens when there is
actually a power outage and the emergency power is required?
once did a tour of large mainframe datacenter (they claimed turning over
a billion dollars in ibm mainframes every 18months ... to keep up with
the business). they weren't satisified with the PDUs that they could get
... so they hired two engineering companies to work with the PDU vendor
to redesign to their requirements. Last I heared was that the PDU vendor
had sold over 1200 of the redesigned units just in the DC beltway area.
