VM Series vCPU limit increase

Resource Manager vCPU quotas for virtual machines and virtual machine scale sets are enforced at two tiers for each subscription, in each region.

The first tier is the Total Regional vCPUs limit (across all VM Series), and the second tier is the per VM Series vCPUs limit (such as the D-series vCPUs). Any time a new VM is to be deployed, the sum of new and existing vCPUs usage for that VM Series must not exceed the vCPU quota approved for that particular VM Series. Further, the total new and existing vCPU count deployed across all VM Series should not exceed the Total Regional vCPUs quota approved for the subscription. If either of those quotas are exceeded, the VM deployment will not be allowed. You can request an increase of the vCPUs quota limit for the VM series from Azure portal. An increase in the VM Series quota automatically increases the Total Regional vCPUs limit by the same amount.

Learn more about quotas on the Virtual machine vCPU quotas page and Azure subscription and service limits page.

You can now request an increase via Help + Support blade or the Usages + Quota blade in the portal.
