The price that we received from IBM was well within your 12% number of
prices we got from second-tier vendors (including one that is a Linux-only
vendor, much like VA is/was). However, the boxes from IBM and Compaq were
MUCH better engineered boxes with far better cooling infrastructures,
which is very inportant in a 1U box. We felt the IBM boxes were enough
better than the boxes from other vendors (at least, non first-tier
vendors), that it was worth a small premium in price.

No, the point for us was *NOT* "commodity stuff", and we already have a
fully-configured E10K. The point for us was to acquire a high-performance
computational platform that produced a good cost/performance ratio on our
codes. Since purchasing our E10000 several years ago, our codes have
changed such that a cluster became a more viable solution for them. If
the E15K, an Origin, or something along those lines could have produced
better (or even reasonably close) performance for the money on our codes,
we would have bought one of them instead.
We aren't Linux/Intel/AMD/clustering zealots. We'll buy whatever
equipment best meets our needs, and it just so happens that right now, a
PC-based Linux cluster was it.
