I thought it read a bit like a chronicle of my recent experiences.

In our experiences over the last two clusters, one was delivered n a
bunch of flat boxes andwe spent several weeks racking, stacking,
cabling, loading, testing, tweaking and then releasing. Or, was that
In our more recent cluster, we took delivery of a purported tested
system, then lived through 2+ weeks of vendor cabling (pretty, if an
extended time to achieve), hardware failures, replacements, BIOS
upgrades (wholesale; shouldn't have been needed), and more hardware
failures. Next time, I want to either get a complete turnkey system or
buy from the various sources and just do it myself, knowing the pitfalls.
