New 6Gb/s RAID or HBA makes more sense for the external storage with SAS & SATA expnader or MPIO modules all the way to 240 drives and 10Meter cable length. Why bother to have 3U to 9U storage server, and spend more money to 2000W power supply and all kind of thermal and cabling problems? 2U-12D, 3U-16D, or 4U-24D with SAS/SATA JBODs allows you to aggregate the data without touching the server end.
