in this category fell on a year-over-year basis. In 2005, scores ranged from 6.16 (HDS) to 5.41 (Sun).
One area that captured our attention in nearly all of the product categories in previous awards is patch management. In most surveys, we've found this area to be among the lowest rated and a differentiator among vendors. This year, HP (6.04) bested HDS (5.97) for the statement "This product requires very few unplanned patches." However, HDS received higher marks (5.86) for "Patches can be applied non-disruptively" vs. HP's 5.76. The statement "This product meets my service-level requirements" received generally high scores, with HDS taking the top spot with a 5.97.
