Hmm. Are you sure it's the best choice? It has a single Cortex A8 (like
the old Beagle Board). The Panda Board has a dual Coretex A9. I've not
benchmarked them, but I would expect the Panda to be a lot faster for
CPU-bound tasks. The iMX53 has the advantage of SATA if you expect to be
I/O limited, but if I were building a "farm" I think I'd seriously consider
NFS and negligible local storage.
My choice of the iMX53 was based mainly on its video features (it has
analogue VGA out, which the Panda doesn't) and more than a bit of
prejudice because I seemed to be the interested only person at CELF last
year who didn't get a free Panda.
Anyway, if you do go with the iMX53, do keep us informed. I'm currently
working on mechanical/electrical things e.g. a box and power supply. Note
that the board seems to have very little capacitance on its 5V power input,
so it can "brown out" if you connect something (via USB or otherwise) that
has non-trivial inrush current. There is also the fact that it powers-on
"off" until you press a button, which I imagine is probably not the behaviour
that you'll want.
Cheers, Phil.
