According to the CLI, the supported boost VMs are:

bash
Copy code
$ az vm list-sizes --location eastus2 | jq -r 

• Experimental_Boost4
• Experimental_Boost8
• Experimental_Boost32
• Experimental_Boost64
• Experimental_Boost192

Is Standard_D8s_v5 a Boost VM or not? Can someone from Azure verify this?

Answer 1

Hi ,

Thanks for reaching out to Microsoft Q&A.

Azure Boost is a system that offloads server virtualization processes traditionally performed by the hypervisor and host OS onto purpose-built hardware and software, enhancing performance, security, and reliability.

The Standard_D8s_v5 virtual machine (VM) is part of the Dsv5-series, which runs on the Intel® Xeon® Platinum 8370C (Ice Lake) processor. This processor features an all-core turbo clock speed of 3.5 GHz with Intel® Turbo Boost Technology, Intel® Advanced-Vector Extensions 512 (Intel® AVX-512), and Intel® Deep Learning Boost.

According to Microsoft's documentation, the Dsv5-series VMs are among those that benefit from Azure Boost.

Therefore, the Standard_D8s_v5 VM is indeed a Boost-enabled VM.

Regarding the CLI output listing VM sizes such as Experimental_Boost4, Experimental_Boost8, etc., these are likely experimental or preview VM sizes specifically designated for testing Azure Boost features. The Standard_D8s_v5 VM, being a production-ready size, also incorporates Azure Boost capabilities.

In summary, the Standard_D8s_v5 VM is a Boost-enabled VM, benefiting from the performance and security enhancements provided by Azure Boost.
