Question

Capacity is not available in this region/zone

Chaitali Rane 0

We are trying to select the compute tier from General Purpose (2-96 vCores) - Balanced configuration for most common workloads TO Memory Optimized (2-96 vCores) - Best for workloads that require a high memory to CPU ratio. Along with this we are trying to select below settings-:

Compute processor: AMD

Compute size: Standard_E8ads_v5(8 vCores, 64GiB memory, 12800 max iops)

Storage size: 1 TiB

After this, we are clicking on Save button.

We are getting error as Deployment failed with below error message-:

Capacity is not available in this region/zone. Please retry after some time. (Code: CapacityNotAvailable)

We have checked that we do have enough capacity based on our quotas.

Answer 1

Hello Chaitali !

Thank you for posting on Microsoft Learn Q&A.

I think the issue is not related to your quota but it is more about the actual hardware capacity in that region for that exact SKU (Memory Optimized + AMD + Standard_E8ads_v5).

Try:

Changing the availability zone or using No preference (for new deployments)
Choosing a different size in the same family (like E4ads_v5 or E16ads_v5)
Switching from AMD to Intel SKUs (like E8ds_v5)
If you can, deploying in a nearby region

If none of those work, I recommend that you open a support ticket for better assistance.
