I am looking to build out a fairly dense setup with nodes having 8 or

Initially plan to have 6 of these nodes. Obviously at this level of
density I need to be able to hot swap a drive if one goes bad. I
was wondering what folks have seen in terms of real work use of
various SATA controllers out there.
Aren't most/all SATA controllers hot-swap by now? Check
http://linux-ata.org/driver-status.html before you buy and you should
be in good shape. I thought it was part of the SATA spec and the
only controllers that didn't support it was "bridged" PATA controllers.
Typically for MogileFS devices it's a waste of money buying a fancy
SATA controller. (If you do want one, then the new 3Ware ones are
pretty good - the ones from 3-4 years ago not so much).
