The vertical distance between mounting holes must consist of sets of three holes spaced (from bottom
to top) 15.9 mm (0.625 in.), 15.9 mm (0.625 in.), and 12.67 mm (0.5 in.) on center (making each three
hole set of vertical hole spacing 44.45 mm (1.75 in.) apart on center). The front and rear mounting
flanges in the rack or cabinet must be 719 mm (28.3 in.) apart and the internal width bounded by the
mounting flanges at least 494 mm (19.45 in.), for the IBM Storage System or eServer
™
