Table 4-3. VSM5-VTSS Floor Loading Specifications
Basic Floor Load*	Maximum Superimposed Floor Load #
730 kg/m2 (149 lbs./ft2)	485 kg/m2 (99 lbs./ft2)

Notes:

•* Load over footprint surface area (7093.7 cm2/1099.5 in2) of an unpackaged VSM5-VTSS cabinet, with a maxi- mum weight of 445 kg/982 lbs., i.e., a VTSS with 64 array disk drives.

•# Assumes minimum Z+Z axis dimension of 185.3 cm/73.0 in. (i.e., cabinet depth 77.1 cm/30.4 in. + front service clearance of 54.1 cm/21.3 in. + rear service clearance of 54.1 cm/21.3 in.), minimum X+X axis dimension of 104.9 cm/41.2 in. (i.e., cabinet width 92.1 cm/36.3 in. + left clearance of 6.4 cm/2.5 in. + right clearance of 6.4 cm/2.5 in.).

•See Figure 4-3 on page 4-53for the location and load of each VTSS cabinet support point.

•Values assume 15 lb./ft2 (73 kg/m2) superimposed dead load over entire area for raised floor, cables, etc., and 15 lb./ft2 (73 kg/m2) live load for personnel and equipment in clearance areas between units.

•Loading of adjacent floor areas must be considered when evaluating overall floor capacity.

•To evaluate floor loading for other possible configurations, consult a structural engineer.
