3. Specify the quantity for the features that are installed in your system.
This tool estimates the power consumption for the specified configuration. The tool does
not
verify that the specified configuration can be physically built.
2.8.6 Cooling requirements
The z13s is an air-cooled system. It requires chilled air, ideally coming from under a raised
floor, to fulfill the air cooling requirements. The chilled air is usually provided through
perforated floor tiles. The amount of chilled air that is required for various temperatures under
the floor of the computer room is indicated in the
z13s Installation Manual for Physical
Planning, GC28-6953.
2.9 Summary of z13s structure
Table 2-14 summarizes all aspects of the z13s structure.
Table 2-14 System structure summary
Power consumption: The exact power consumption for your system will vary. The object
of the tool is to produce an
estimation
of the power requirements to aid you in planning for
your system installation. Actual power consumption after installation can be confirmed on
the HMC System Activity Display.
