Working with the 3D temperature map

[EcoStruxureIT]

You can review the data center temperature map in 3D as a calculated or measured map.

The calculated map provides an estimate based on the maximum load servers would have (nameplate).

The measured map is more accurate because it has more detailed data available. It is based on real sensor readings retrieved through discovered devices rather than estimates.

Tip

Room size limitation: The 3D temperature map currently does not support rooms bigger than 70x100 m.

Unsupported configurations: Deactivating a cooling unit does not affect the airflow in 3D as this is currently not supported. You can omit the airflow of a cooling unit in 3D with these workarounds.

Configuring temperature map based on real sensor readings

1. Retrieve live values from the sensors in the data center.
   1. Configure external system integration with a system that provides real temperature measurements. 
   2. In Planning > Device Association, discover and associate devices. See more here.
2. Position the sensors in the correct locations in the model.
   1. In the Association map overlay, map each temperature sensor to the correct physical location (devices, racks, or rooms) using drag'n'drop.
      For example, drag an InRow CRAC upper plenum exhaust temperature sensor to the upper position in the rear of the CRAC.
   2. Specify a precise location in a rack.
      1. Right-click the rack that contains the sensor and select Properties>Device Sensor.
      2. Use the X, Y, Z % fields to define the location expressed as a percentage on the axes, starting with 0%, 0%, 0% in the lower left corner.
3. Calculate the 3D temperature map.
   1. Open the 3D view to preview the sensors in the correct locations.
   2. In Cooling plane type, select Measured plane and click Calculate.

Tip

You can have multiple rooms open in the 3D view at a time. When you have opened a room in 3D view or applied changes to the configuration, click Calculate to regenerate the calculations and show the updated view.

Zoom and rotate using the navigation settings to the right to see specific areas in the layout.

Review and customize the display settings to the right.

Click the icon at the bottom of the thermometer to customize the temperature thresholds and color scheme.
If the thermometer does not show, click the arrow icon to invoke it.

Measured cooling plane quality  

A rack can get the inlet temperature by any of these methods:

• Manual measured temperature (on rack properties)
• Servers associated with external system integration

The outlet temperature on the rack (the derived temperature) can be calculated based on the load on the server/rack and the inlet temperature.

If the Only measured setting is enabled, only actual measurements from other systems or manually entered measurements will be included.

If the Measured and derived setting is enabled, the derived temperatures will also be included in the temperature map.

To enable or disable Measured and derived setting go to Preferences > Temperature Map > Measured cooling plane quality.

Enable or disable derived setting
