Virtualization plays a crucial role in data center consolidation and thereby helps in the reduction of hardware footprint in the data centers. Virtualization helps in the saving of power consumption and floor space in data centers which improves the overall efficiency and curbs carbon emissions that result from IT infrastructure growth. Use this page to configure green score data in VMware Aria Operations for physical data centers that have been added to a vCenter Server account, a VMware Cloud on Dell EMC account, or to a VMware Cloud Foundation account and configured for green score. Using green score, organizations can track where they are in their sustainability journey and how they are progressing over time.

| Physical Data Centers (map/list) | Displays the configured physical data centers in a map view or in a list. Select the physical data center for which you want to see green score details in a map view or from a list using the options at the top right corner. To reset to the Organizational level, click the X button for the selected physical data center. |
| Physical Data Centers by Greenscore | Displays the number of all physical data centers. At the bottom of the panel, you can view the number physical data centers that are configured (green in color) and not configured (gray in color) for green score. For configured physical data centers, you can view the range of green score values applicable to the configured physical data center. |
| Greenscore Meter | Indicates how sustainable a company is. A higher score indicates a greater green score. Green score is calculated based on the different values calculated for workload efficiency, resource utilization, virtualization, power source, and hardware efficiency. |
| Greenscore Trend | Indicates the green score trend of the company. You can view daily, weekly, and monthly trends. |
| Clean Demand | |
| Workload Efficiency | Measures the wastage in the data center and calculates a score based on various waste sources. The workload efficiency value is calculated based on different metrics, such as powered off VMs, oversized VMs, idle VMs, snapshots, and orphaned disks. The metrics are as follows: Total Consumption CPU = (vCenter) CPU|vCPUs Allocated on all Powered On Consumers Total Consumption Memory (GB) = (vCenter) Memory|Host Usage (KB) Total Consumption Disk (TB) = (vCenter) Disk Space|Total Provisioned Disk Space (GB) Oversized VM|vCPU = (VM) Summary|Oversized|Virtual CPUs and Oversized VM|Memory (GB) = (VM) Summary|Oversized|Memory (KB) - These metrics are used to calculate workload efficiency only for powered on VMs. This means that vCPUs and memory of powered off and oversized VMs are excluded from the calculation. Idle VM|Disk (TB) = (Cluster) Reclaimable|Idle VMs|Disk Space (GB) Idle VM|vCPU = (Cluster) Reclaimable|Idle VMs|CPU (vCPUs) Idle VM|Memory (GB) = (Cluster) Reclaimable|Idle VMs|Memory (KB) Powered Off VM|Disk (TB) = (Cluster) Reclaimable|Powered Off VMs|Disk Space (GB) Snapshot|Disk (TB) = (Cluster) Reclaimable|VM Snapshots|Disk Space (GB) Orphaned VMDK|Disk (TB) = (Datastore) Reclaimable|Orphaned Disks|Disk Space (GB) |
| Lean Operations | |
| Resource Utilization | Provides a value based on server and storage utilization. The score is based on the utilization of hardware from absolute capacity without considering buffers and HA. Here are the metrics used: Total ESXi Hosts CPU Utilization (GHz) = (vCenter) CPU|Usage (MHz) Total ESXi Hosts CPU Capacity (GHz) = (vCenter) CPU|Total Capacity (MHz) Total ESXi Hosts Memory Utilization (TB) = (vCenter) Memory|Host Usage (KB) Total ESXi Hosts Memory Capacity (TB) = (vCenter) Memory|Total Capacity (KB) Organization/Physical Total datastores capacity = (vCenter) Disk Space|Total Capacity (GB) Total datastores utilization = (vCenter) Disk Space|Utilization (GB) Total RDM = Sum((VM) Virtual Disk \ Configured Size) |
| Virtualization | Virtualization score is calculated based on the virtualization percentage of compute, storage, network, and desktop entered in the corresponding physical data center's configuration. The formula is a weighted average of virtualization percentages with 40%, 30%, 20%, and 10% corresponding weights. |
| Green Supply | |
| Power Source | The score is based on the carbon intensity of the power source used. For example, traditional coal based power sources will have a carbon intensity rate of 888 g/kWh while wind based power source will have a carbon intensity of 26 only (Reference : WNA Report - Comparison of Lifecycle Greenhouse Gas Emissions of Various Electricity Generation Sources. Note: A 100% badge score indicates zero carbon emission. Each value is calculated based on the share of the power sources entered in the Organization Details page, after which the average value is calculated. The value for each of the power resources is calculated as follows:Green Factor Shares (100%) Adjusted Score (Green Factor * Shares) Coal = 17% (Green Factor) Oil = 31% (Green Factor) Natural Gas = 53% (Green Factor) Solar PV = 92% (Green Factor) Biomass = 96% (Green Factor) Nuclear = 97% (Green Factor) Hydroelectric = 98% (Green Factor) Wind = 98% (Green Factor)
Note: Shares are user inputs in the corresponding physical data center's page.

| Hardware Efficiency | The hardware efficiency badge is based on the fact that new generation hardware is more energy efficient than the old generation hardware - by running more workloads on the same sized hardware and also the ability of hardware to optimize energy consumption. The efficiency of hardware which includes server, storage, network, and desktop is based on the average age of the hardware entered in the Organization Details page. However, you can change and input ages that are specific to the physical data center. For example, if you had entered the age of your servers as 2 years, then the hardware efficiency for servers would be 80%, because the useful life duration is considered as 10 years. |
Power Consumption Chart
The power consumption chart displays the cumulative power consumption for the last one month. It is calculated using the power usage metrics and is the sum of the last month's daily power consumption. When you click the Power Consumption option, you can also view the Power Consumption trend which can be daily, weekly, or monthly.
Carbon Footprint Chart
The carbon footprint chart displays the carbon emission for the last one month. When you click the Carbon Footprint option, you can also view the Carbon Footprint trend which can be daily, weekly, or monthly.
Environmental Impact
The environmental impact is depicted in terms of carbon emissions from the number of smart phones charged, as per the calculations based on Greenhouse Gas Equivalencies Calculator.
