Azure announces new AI optimized VM series featuring AMD’s flagship MI300X GPU
In our relentless pursuit of pushing the boundaries of artificial intelligence, we understand that cutting-edge infrastructure and expertise is needed to harness the full potential of advanced AI. At Microsoft, we've amassed a decade of experience in supercomputing and have consistently supported the most demanding AI training and generative inferencing workloads. Today, we're excited to announce the latest milestone in our journey. We’ve created a virtual machine (VM) with an unprecedented 1.5 TB of high bandwidth memory (HBM) that leverages the power of AMD’s flagship MI300X GPU. Our Azure VMs powered with the MI300X GPU give customers even more choices for AI optimized VMs.
Performance considerations for large scale deep learning training on Azure NDv4 (A100) series
Modern DL training jobs require large Clusters of multi-GPUs with high floating-point performance connected with high bandwidth, low latency networks. The Azure NDv4 VM series is designed specifically for these types of workloads. We will be focusing on HPC+AI Clusters built with the ND96asr_v4 virtual machine type and providing specific optimization recommendations to get the best performance.

Contributors: Davide Vanzo, Yuval Mazor, Jesse Lopez DeepSeek-R1 is an open-weights reasoning model built on DeepSeek-V3, designed for conversational AI, coding, and complex problem-solving. It has gained significant attention beyond the AI/ML community due to its strong reasoning capabilities, often competing with OpenAI’s models. One of its key advantages is that it can be run locally, giving users full control over their data. The NDv5 MI300X VM features 8x AMD Instinct MI300X GPUs, each equipped with 192GB of HBM3 and interconnected via Infinity Fabric 3.0. With up to 5.2 TB/s of memory bandwidth per GPU, the MI300X provides the necessary capacity and speed to process large models efficiently - enabling users to run DeepSeek-R1 at full precision on a single VM. In this blog post, we’ll walk you through the steps to provision an NDv5 MI300X instance on Azure and run DeepSeek-R1 for inference using the SGLang inference framework. Launching an NDv5 MI300X VM Prerequisites Check that your subscription has sufficient vCPU quota for the VM family “StandardNDI Sv 5MI300X” (see Quota documentation). If needed, contact your Microsoft account representative to request quota increase. A Bash terminal with Azure CLI installed and logged into the appropriate tenant. Alternatively, Azure Cloud Shell can also be employed. Provision the VM 1. Using Azure CLI, create an Ubuntu-22.04 VM on ND_MI300x_v5: az group create --location <REGION> -n <RESOURCE_GROUP_NAME> az vm create --name mi300x --resource-group <RESOURCE_GROUP_NAME> --location <REGION> --image microsoft-dsvm:ubuntu-hpc:2204-rocm:22.04.2025030701 --size Standard_ND96isr_MI300X_v5 --security-type Standard --os-disk-size-gb 256 --os-disk-delete-option Delete --admin-username azureadmin --ssh-key-values <PUBLIC_SSH_PATH> Optionally, the deployment can utilize the cloud-init.yaml file specified as --custom-data <CLOUD_INIT_FILE_PATH> to automate the additional preparation described below: az vm create --name mi300x --resource-group <RESOURCE_GROUP_NAME> --location <REGION> --image microsoft-dsvm:ubuntu-hpc:2204-rocm:22.04.2025030701 --size Standard_ND96isr_MI300X_v5 --security-type Standard --os-disk-size-gb 256 --os-disk-delete-option Delete --admin-username azureadmin --ssh-key-values <PUBLIC_SSH_PATH> --custom-data <CLOUD_INIT_FILE_PATH> Note: The GPU drivers may take a couple of mintues to completely load after the VM has been initially created. Additional preparation Beyond provisioning the VM, there are additional steps to prepare the environment to optimally run DeepSeed, or other AI workloads including setting-up the 8 NVMe disks on the node in a RAID-0 configuration to act as the cache location for Docker and Hugging Face. The following steps assume you have connected to the VM and working in a Bash shell. 1. Prepare the NVMe disks in a RAID-0 configuration mkdir -p /mnt/resource_nvme/ sudo mdadm --create /dev/md128 -f --run --level 0 --raid-devices 8 $(ls /dev/nvme*n1) sudo mkfs.xfs -f /dev/md128 sudo mount /dev/md128 /mnt/resource_nvme sudo chmod 1777 /mnt/resource_nvme 2. Configure Hugging Face to use the RAID-0. This environmental variable should also be propagated to any containers pulling images or data from Hugging Face. mkdir –p /mnt/resource_nvme/hf_cache export HF_HOME=/mnt/resource_nvme/hf_cache 3. Configure Docker to use the RAID-0 mkdir -p /mnt/resource_nvme/docker sudo tee /etc/docker/daemon.json > /dev/null <<EOF { "data-root": "/mnt/resource_nvme/docker" } EOF sudo chmod 0644 /etc/docker/daemon.json sudo systemctl restart docker All of these additional preperation steps can be automated in VM creation using cloud-init. The example cloud-init.yaml file can be used in provisioning the VM as described above. #cloud-config package_update: true write_files: - path: /opt/setup_nvme.sh permissions: '0755' owner: root:root content: | #!/bin/bash NVME_DISKS_NAME=`ls /dev/nvme*n1` NVME_DISKS=`ls -latr /dev/nvme*n1 | wc -l` echo "Number of NVMe Disks: $NVME_DISKS" if [ "$NVME_DISKS" == "0" ] then exit 0 else mkdir -p /mnt/resource_nvme # Needed incase something did not unmount as expected. This will delete any data that may be left behind mdadm --stop /dev/md* mdadm --create /dev/md128 -f --run --level 0 --raid-devices $NVME_DISKS $NVME_DISKS_NAME mkfs.xfs -f /dev/md128 mount /dev/md128 /mnt/resource_nvme fi chmod 1777 /mnt/resource_nvme - path: /etc/profile.d/hf_home.sh permissions: '0755' content: | export HF_HOME=/mnt/resource_nvme/hf_cache - path: /etc/docker/daemon.json permissions: '0644' content: | { "data-root": "/mnt/resource_nvme/docker" } runcmd: - ["/bin/bash", "/opt/setup_nvme.sh"] - mkdir -p /mnt/resource_nvme/docker - mkdir -p /mnt/resource_nvme/hf_cache # PAM group not working for docker group, so this will add all users to docker group - bash -c 'for USER in $(ls /home); do usermod -aG docker $USER; done' - systemctl restart docker Using MI300X If you are familiar with Nvidia and CUDA tools and environment, AMD provides equivalents as part of the ROCm stack. MI300X + ROCm Nvidia + CUDA Description rocm-smi nvidia-smi CLI for monitoring the system and making changes rccl nccl Library for communication between GPUs Running DeepSeek-R1 1. Pull the container image. It is O(10) GB in size, so it may take a few minutes to download. docker pull rocm/sgl-dev:upstream_20250312_v1 2. Start the SGLang server. The model (~642 GB) is downloaded the first time it is launched and will take at least a few minutes to download. Once the application outputs “The server is fired up and ready to roll!”, you can begin making queries to the model. docker run \ --device=/dev/kfd \ --device=/dev/dri \ --security-opt seccomp=unconfined \ --cap-add=SYS_PTRACE \ --group-add video \ --privileged \ --shm-size 32g \ --ipc=host \ -p 30000:30000 \ -v /mnt/resource_nvme:/mnt/resource_nvme \ -e HF_HOME=/mnt/resource_nvme/hf_cache \ -e HSA_NO_SCRATCH_RECLAIM=1 \ -e GPU_FORCE_BLIT_COPY_SIZE=64 \ -e DEBUG_HIP_BLOCK_SYN=1024 \ rocm/sgl-dev:upstream_20250312_v1 \ python3 -m sglang.launch_server --model deepseek-ai/DeepSeek-R1 --tp 8 --trust-remote-code --chunked-prefill-size 131072 --enable-torch-compile --torch-compile-max-bs 256 --host 0.0.0.0 3. You can now make queries to DeepSeek-R1. For example, these requests to the model from another shell on same host provide model data and will generate a sample response. curl http://localhost:30000/get_model_info {"model_path":"deepseek-ai/DeepSeek-R1","tokenizer_path":"deepseek-ai/DeepSeek-R1","is_generation":true} curl http://localhost:30000/generate -H "Content-Type: application/json" -d '{ "text": "Once upon a time,", "sampling_params": { "max_new_tokens": 16, "temperature": 0.6 } }' Conclusion In this post, we detail how to run the full-size 671B DeepSeek-R1 model on a single Azure NDv5 MI300X instance. This includes setting up the machine, installing the necessary drivers, and executing the model. Happy inferencing!
