I'm looking into options to shift my moodledata/filedir data over to a local NAS/SAN. My host OS is Ubuntu. My hope is to find a reasonably priced device that will support a few TB's. Does anyone have any experience or recommendations along these lines? How many IOPS are enough? iSCSI verses FC? Sorry, but I've dug around too much and listed to too many vendors at this point. Any help would be appreciated.
