Use this dashboard to view the reduction in carbon footprint achieved using virtualization and also the reduced number of servers, reduced power consumption, and reduced carbon emission achieved using virtualization.
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 Greener Planet Contribution widget provides details of power saved for the vSphere World object in percent and compares the power consumption of a vCenter Server environment before and after virtualization assuming that 100W is the power consumption for a low-range server before virtualization.
- Use the CO2 Emissions Saved and Electricity Cost Saving widgets to view the sum of carbon emissions and electricity saved for the last 24 hours.
- Using the Power Consumption widget, you can view power consumed before and after virtualization. Power consumption before virtualization is based on the assumption that a low-range server consumes 100W. Hence, power consumption before virtualization is calculated using the count of VMs, which is the number of physical servers if not virtualized, at 100W per server.
- Using the CO2 Emission widget, you can view CO2 emissions before and after virtualization. CO2 emission per kWh is assumed as 0.709 kg (Based on reference values from Greenhouse Gas Equivalencies Calculator). The value is calculated in Kilogram (kg).
- The CO2 Emission Chart and the Power Consumption Chart provides CO2 emissions (in kg) for the last 24 hours and power consumption (in kWh) for the last 24 hours respectively.
Custom Values
- Predefined Values
- Power consumption of a small server (1 socket, 10 cores, 32 GB RAM) = 0.1 kW (Assumption used in calculating power consumption before virtualization).
- CO2 emission per kWh = 0.709 kg (Reference values from Greenhouse Gas Equivalencies Calculator).
- Electricity Cost per kWh = $0.108 (Reference from VMware TCO Reference Calculator).
- You can add a custom property for CO2 emission and electricity cost which can be applied per cluster compute resource.
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. You can add custom values for Cost of Power to each cluster compute resource by creating a custom property with name Electricity Rate and type as Numeric and the relevant custom values.
Note: If you do not define custom properties, out of the box values for CO2 emission and electricity costs are used.
Points to Note
Your actual savings may be much more. The following are not included:
- Physical buildings and land. With virtualization, you consume less carbon foot print. This results in less physical rack.
- Network equipment. Fewer number of physical servers results in lesser network ports. Because firewall, load balancers, IDS, and IPS can be virtual machines, you have less equipment.
- Other components like UPS, lighting, cooling, and labor.
