User Guide

• Space and network capacities are determined by the rack and its contents, so there is no ability to
specify maximums.
• Default maximum is a measurement, defined by plan, as the default maximum capacity for any newly placed
floor-level assets.
For example, if the data center's cooling infrastructure cannot handle a rack producing more than 3000
BTU/hr of heat, then the default maximum capacity for the floor plan would likely be 2500 BTU/hr,
leaving a 500 BTU/hr margin for error.
• Plan maximum is a measurement, defined by plan, as the aggregate consumption limit of all assets on the
floor plan.
• Remaining is the difference between maximum capacity and consumption. For example, if a 4 kW rack is
filled with 50 light bulbs (60 watt), the remaining capacity would be (4000 - 50 * 60) watt or 1 kW.
NOTE: When capacities max values for power, heat and weight have not been set on an asset, there will be no metric for calculating
remaining capacities for them respectively. If there is no max value for power on an asset, the asset will not be colorized for Power-
Remaining; it will be white. This is the same for weight and heat.
Metrics
The application measures five capacity metrics:
• Power - Measured in watts or kilowatts - Real world power consumption varies radically depending upon
configuration and usage.
• Heat - Measured in BTU/hr - A measure of the heat produced by the devices. Technically, it is heat
production and cooling consumption, the heat produced by a device related to its power consumption.
• Weight - Measured in pounds or kilograms - Typically not derated.
• Space - Measured in rack units - This is determined directly from the asset type, with no opportunity to
derate.
• Network - Measured in number of ports - This is determined by the network switches installed in a rack,
with no opportunity to derate.
Color range
Colorization is shown for one metrics at a time with no attempt to consolidate metric visualizations into one
view. Floor-level assets are colored based on a color scale, evenly distributed over a continuous range of colors.
The colors range from green (for good) through yellow to red (for bad). Red should only be used as an indication
that something is wrong, such as a floor-level asset being beyond capacity.
While the application automatically chooses the upper and lower limits for the color scale, you have the
capability of adjusting the range. This helps in situations where outliers distort the colorization.
Color legend
The color range is visualized by a color legend. The legend gives you details as to what the particular colors
mean. The colors on the floor plan are actually a continuous range of colors, so the legend is just a sampling of
colors throughout that range.
To visually indicate consumption on the plan, floor level assets are colorized based on consumption. The color
range is based on the minimum and maximum values.
