An Azure service that is used to provision Windows and Linux virtual machines.
Thanks for the details. Based on Microsoft documentation, there is not a single published list of GPU VM families that are always quota-approvable for all Sponsorship subscriptions.
What can be confirmed:
For NC-family GPU sizes (including NCasT4_v3), Azure documents that quota starts at 0 and that "your subscription level might not support selecting or deploying these SKUs." Source: https://learn.microsoft.com/azure/virtual-machines/sizes/gpu-accelerated/nc-family#series-in-family
Quotas can be adjustable or non-adjustable, and non-adjustable limits can be tied to subscription scope. If increase is unavailable, Azure directs you to open a support request or use other series/regions. Source: https://learn.microsoft.com/azure/quotas/per-vm-quota-requests
Sponsorship is a distinct Azure offer type (MS-AZR-0036P), so entitlement behavior can differ from PAYG. Source: https://learn.microsoft.com/azure/cost-management-billing/costs/understand-cost-mgt-data#supported-microsoft-azure-offers
Given your denied NCasT4_v3 request, the safest conclusion is:
- NCasT4_v3 is currently not approvable for your current Sponsorship subscription/region combination.
- Other GPU families may or may not be allowed, but must be validated directly in your subscription.
Recommended next check (authoritative for your tenant):
- Azure portal -> Quotas -> Compute -> filter for GPU families (NC/ND/NV) in your target region.
- Check whether each family is marked adjustable vs non-adjustable.
- Try "Request quota" for each visible GPU family.
- If unavailable, open a quota support request from the same pane to get an explicit allow/deny by Azure Support.
If all GPU families are non-adjustable/denied in your Sponsorship subscription, then yes, you should plan an alternative deployment route (for example, a PAYG subscription for GPU inference workloads).
Please 'Upvote' (Thumbs-up) and 'Accept' as answer if the response was helpful. This will be helpful to other community members who face similar issues.
