On the **Estimate cost** page, click **Start** in the **Google Cloud VMware Engine** card.\n2. Choose a pricing track. By default, the **3-year committed use discount** with monthly payment is selected.\n3. In the **Workloads** section, click **Add a workload**.\n4. Enter the name of your workload and select the **Workload type**.\n5. In the **GCVE service type** section, select one of the available options:\n - **Fully licensed:** Purchase your VMware Cloud Foundation licenses from Google, as part of your VMware Engine nodes.\n - **Portable license:** Use your VMware Cloud Foundation licenses on VMware Engine.\n6. In the **GCVE protected** section, select if you want to enable backup and disaster recovery on your VMware Engine nodes, if available, or if you don't want to enable this option.\n7. In the **Location** section, select the region where you want to host your environment. The available VMware nodes depend on the region that you select.\n8. In the **Basic workload requirements** section, enter the following details:\n 1. Optional: The number of VMs in your environment\n 2. The number of vCPUs\n 3. The total memory\n 4. The total storage\n9. Optional: In the **Advanced Google Cloud VMware Engine sizing** section, specify the sizing of your environment. For more information, see [Specify optional sizing details](#specify-sizing).\n10. To confirm the configuration of your workload, click **Done**.\n11. If you have multiple workloads, click **Add a workload** and repeat the previous steps.\n12. In the **Node configuration** section, review the recommended configuration. To change the vSAN policy of the node, click **Change**.\n13. To review the estimate for VMware Engine workloads, click **Submit** . The VMware Engine cost estimate is displayed on the [results page](#view-and-export-results).\n\nSpecify optional sizing details\n-------------------------------\n\nThis section describes how to specify the optional details in the\n**Google Cloud VMware Engine sizing** section.\n\n1. In the **CPU Overcommit** field, enter the overcommit factor for the CPU.\n Use the following values according to your workload type:\n\n 1. `1-3` for low overcommit\n 2. `4-6` for moderate\n 3. `7-12` for high\n\n The default value is `6`.\n2. In the **RAM Overcommit field** , enter the overcommit factor for the RAM.\n The default value is `1`.\n\n3. In the **vSAN settings section**, specify the following details:\n\n 1. **Optimization:** select one of the available optimization types:\n\n 1. **None**\n 2. **Compression**\n 3. **Deduplication and compression**\n\n The default value is **Compression**.\n 2. **Optimization factor:** select the ratio between the allocated storage\n and the actual amount written to the vSAN. The default value is `1.7`.\n\n 3. **SLA threshold:** specify the reserved vSAN storage capacity, in %,\n to perform updates, upgrades and other operational tasks.\n The default value is `20%`.\n\n 4. To support VMs with VMDKs larger than 8 TB, select **Use large VMDKs**.\n\n 5. To enable vSAN Operations Reserve, select **Use OR buffer**.\n\n4. In the **Advanced Google Cloud VMware Engine settings** section, specify the\n following details:\n\n 1. **System CPU:** specify the maximum amount of system CPU consumption, in %. The default value is `15%`.\n 2. **System RAM:** specify the default system RAM reservation, in %. The default value is `5%`.\n 3. **HT Weight:** specify the amount of hyperthreading boost effect, in %. The default value is `25%`.\n 4. To host management appliances in the cluster, such as vCSA, NSX-T Manager, NSX-T Edge Node, select **Management Cluster**.\n 5. If you want to reserve capacity for HCX Mesh components, select **HCX Mesh Deployed**.\n 6. **NSX-T Edge Size:** select one of the available sizes for NSX-T Edge:\n 1. **Large**\n 2. **Extra Large**\n\nTo reset the default values of the sizing configuration, click\n**Reset to defaults**.\n\nReview and export estimation results\n------------------------------------\n\nThe steps to review and export estimate results are\n[common for all](/migration-center/docs/estimate/review-and-export-results) calculators.\n\nIn addition, the overall estimate for VMware Engine is\ndisplayed in a separate result card as well. This cost estimate is based on the\ndefault assumption and the inputs you've provided. By default, the calculator\nrecommends the node configuration with the lowest total cost of ownership (TCO).\nTo edit the node configuration, including the vSAN policy, in the total\nestimate page, click **Edit**.\n\nTo view the details of this cost estimate and the breakdown of the costs for\neach workload, click **View details**.\n\nWhat's next\n-----------\n\n- See how to [review and export the estimate results](/migration-center/docs/estimate/review-and-export-results)."]]
