Storage controllers
Dell's RAID controller options offer performance improvements, including the fPERC solution. fPERC provides a base RAID HW
controller without consuming a PCIe slot by using a small form factor and high-density connector to the base planar.
15G PERC Controller offerings will be a heavy leverage of 14G PERC family. The Value Performance levels will carry over to
15G from 14G. New to 15G, is the Harpoon-based Premium Performance tier offering. This high-end offering will drive IOPs
