Equipment weight
The floors, elevators, and ramps must be able to support the weight of the
delivered equipment as it is moved to the installation location. Spreader
plates may be required to distribute the load and protect the floor as the
equipment is moved from the receiving area to the installation location.
Consult the system bill of materials to establish the approximate weight of
the equipment. See the next paragraph for information about calculating
the exact weight of the equipment.
The weight for a fully configured storage system can reach 6165 pounds /
2793 kilograms. The exact weight of the equipment depends on the storage
system configuration. The following table provides weights of typical system
configurations.

Storage Requirements
If the equipment must be stored after delivery and prior to installation, the
storage location must meet the storage environmental requirements for the
HUS VM storage system. See Table 4-11: HUS VM environmental
specifications on page 4-14 in this chapter for environmental storage
requirements.
Data center requirements
The data center must meet the following general requirements. Detailed
mechanical, electrical, and environmental requirements are listed in the
tables in the next section.
Note: The data in the following table was taken from measurements of a
system in a controlled environment. To calculate the power draw, current
draw, and heat output of a specific system, see Table 4-10: HUS VM
component specifications on page 4-13 or (easier) use the Power and
Weight calculator at the following URL.
