    Hello @Sachin Raorane,

    Since you are trying to configure a VM with 128 GB RAM and 16 vCPUs, you need to use the E-series, as shown below. If you encounter any quota-related issues while configuring the VM in your selected region, please submit a quota increase request if the required quota is not available.

    Quotas are applied per resource group, subscriptions, accounts, and other scopes. For example, your subscription might be configured to limit the number of vCPUs for a region. If you attempt to deploy a virtual machine with more vCPUs than the permitted amount, you receive an error that the quota was exceeded.

    Please check this command- az vm list-usage --location "West US" --output table

    To request a quota increase, go to the portal and file a support issue. In the support issue, request an increase in your quota for the region into which you want to deploy.

    Some quotas let you specify a quota limit that's submitted for review and either approved or rejected. If your limit is rejected, you'll see a link to open a support request.

    Note- Remember that for resource groups, the quota is for each individual region, not for the entire subscription. If you need to deploy 30 vCPUs in West US, you have to ask for 30 Resource Manager vCPUs in West US. If you need to deploy 30 vCPUs in any of the regions to which you have access, you should ask for 30 Resource Manager vCPUs in all regions.

    Please follow this link for quota request: https://learn.microsoft.com/en-us/azure/azure-resource-manager/troubleshooting/error-resource-quota?tabs=azure-cli#solution

    Please let me know if you have any further queries. Thank You!

    To create an Azure VM with 128GB of RAM and 16 vCPUs, you can use the E16s_v3/v4/v5 VM types, which meet your specifications. However, if you are encountering resource quota issues, it may be necessary to request a quota increase for the vCPUs in your Azure subscription.

    Here are the steps you can follow to address the quota issue:

    1. Check Current Quotas: Use the Azure CLI or Azure portal to check your current vCPU quotas.
    2. Request Quota Increase: If your current quota is insufficient, you can request an increase for the vCPU quota through the Azure portal or by using CLI commands.
    3. Emergency Deployment: If this is an emergency requirement, ensure to specify the urgency in your quota request to expedite the process.

    Make sure to also select Windows Server 2019 as your operating system during the VM creation process.
