General site requirements
The customer site must accommodate the delivery and movement of the
equipment from the receiving dock to the installation location in the data
center.
Equipment clearances
Receiving area: The receiving dock, storage area, and receiving area must
be large enough to allow movement of and access to crated or packed
equipment. The dimensions of a shipping crate for a single rack are shown
in the following table.
Table 4-1: HUS VM shipping crate dimensions
Other areas: The hallways, doorways, ramps, and elevators must be large
enough to allow a single unpacked rack to be moved to the installation
location. Unless the distance between the receiving dock and the data
center is very long, HUS VM storage systems are typically unpacked in the
receiving area and the individual racks with pre-installed equipment are
rolled on their casters to the data center. The following table provides the
dimensions of the HUS VM rack.
