Use this dashboard to identify idle VMs in the data center, power off/delete idle VMs to reduce power consumption and improve data center efficiency, and identify remediation plans to offset the damage caused by those idle VMs which cannot be removed.
How to Use the Dashboard
- The banner at the top of the dashboard is a sample image, and you can upload your company logo, tag line, and so on.
- The Cluster's Idle VM table provides a list of clusters with reclaimable memory ,vCPUs, and disk space from idle VMs. You can also view the total resources that can be reclaimed from idle VMs. Click a cluster row to view the relevant sustainability metrics.
- Use the Relevant Metrics of Selected Cluster widget to view metrics of the selected cluster such as, power wasted by idle VMs (Wh), CO2 emissions by idle VMs (kg), trees to offset CO2 emission of idle VMs.
- The Wasted Power from Idle VMs heatmap allows you to view vSphere clusters configured to display wasted power from idle VMs. Power in watt-hour (Wh) is used to build the heatmap. A threshold value of 800 Wh changes the heatmap to red.
- The CO2 Emission from Idle VMs heatmap allows you to view vSphere clusters configured to display CO2 Emission from idle VMs. CO2 emission in kilogram (kg) is used to build the heatmap. A threshold value of 750 kg changes the heatmap to red.
- The Trees Required to Compensate heatmap allows you to view vSphere clusters configured to display the number of trees to be planted to compensate for the damage caused by idle VMs. A threshold value of 70 trees changes the heatmap to red
Custom Values
- Predefined Values
- Tree offset for CO2 Emission = 16.511 Kg (36.4 pounds of carbon per tree. Refer to Greenhouse Gases Equivalencies Calculator) which is equivalent to 36.4/2.2046 Kg of carbon per tree).
- CO2 emission per kWh = 0.709 Kg ( Reference values from Greenhouse Gas Equivalencies Calculator).
- Custom values for CO2 emission can be applied per cluster compute resource by adding a custom property.
Custom values of CO2 emission per kWh can be added to each cluster compute resource by creating a custom property with the name CO2 Emission and type as Numeric and the relevant custom values. Custom values of tree offset to compensate CO2 emission can be added to each cluster compute resource by creating a custom property with the name Trees to Offer and type as Numeric and the relevant custom values.
Note: If no custom properties are defined, out of the box values for CO2 emission are used.
