I am looking to build out a fairly dense setup with nodes having 8 or so SATA drive slots for about 6 TB per node. 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).
