Didn't have a chance to respond before ...
I think the real major issue compared to the "olden days" is that if
things work out correctly a) the actual incremental cost of adding HPC
computing/storage capability is *far* less than it was before, and as
importantly, b) you are not locked into a vendor or a technology the way
you used to be in the "bad old days."
The second is said somewhat tongue-in-cheek as the rise of more powerful
IT groups have sometimes thwarted nascent HPC groups from buying what
they want/need. If your university has a purchase agreement with a big
tier-1 vendor, you fall squarely in this mix. You can't easily buy what
you need, but you can easily buy from a particular vendor. Which might
serve an administration deploying lots of web servers well, but might
not be the right approach to building an HPC infrastructure. It gets
... erm ... interesting ... when you need to explain the utility of
infinband, or why stacked switches are a *very bad idea* or why SANs
aren't what most HPC shops need for fast storage ... list goes on.
But thats a conversation for a different thread.
