Azure’s ND GB200 v6 Delivers Record Performance for Inference Workloads
Achieving peak AI performance requires both cutting-edge hardware and a finely optimized infrastructure. Azure’s ND GB200 v6 Virtual Machines, accelerated by the NVIDIA GB200 Blackwell GPUs, have already demonstrated world record performance of 865,000 tokens/s for inferencing on the industry standard LLAMA2 70B
Performance analysis of DeepSeek R1 AI Inference using vLLM on ND-H100-v5
Introduction The DeepSeek R1 model represents a new frontier in large-scale reasoning for AI applications. Designed to tackle complex inference tasks, R1 pushes the boundaries of what’s possible—but not without significant infrastructure demands. To deploy DeepSeek R1 effectively in an inference service like vLLM, high-performance hardware is essential. Specifically, the model requires two Azure ND_H100_v5 nodes, each equipped with 8 NVIDIA H100 GPUs, totaling 16 H100s. These nodes are interconnected via InfiniBand and NVLink, ensuring the bandwidth and latency characteristics necessary to support the model’s massive memory footprint and parallel processing needs. In this post, we’ll present inference benchmark results for DeepSeek R1, measuring performance across GPU utilization, memory throughput, and interconnect efficiency. While R1 excels in reasoning tasks, it’s important to recognize that such models are not universally optimal. For many general-purpose AI applications, smaller models like Llama 3.1 8B offer a compelling alternative, delivering sufficient accuracy and performance at a fraction of the cost. We explore the performance characteristics of DeepSeek R1 and help you decide when a large reasoning model is worth the investment—and when a leaner solution might be the better choice. Benchmark environment 2 ND_H100_v5 nodes (16 H100) were required to load the DeepSeek R1 model into GPU memory. vLLM was used to set-up the online inference server using a single API server endpoint. vLLM bench (specifically hugging face AI-MO/aimo-validation-aime) was used to run the inference benchmark. Detailed specifications are available in the tables below. Results Reasoning model’s additional chain of thought tokens We show that DeepSeek R1 generates many additional tokens (for chain of thought), which helps reasoning models answer complex logical questions. In this example the DeepSeek R1 generates 1162 completion tokens, but Llama 3.1 8B only generates 37. This example also demonstrates that while non-reasoning models may struggle with this seemingly simple logical question, reasoning models like DeepSeek R1 can solve it—though they require significantly more intermediate tokens to do so. #!/bin/bash curl http://localhost:8000/v1/chat/completions \ -H "Content-Type: application/json" \ -d '{ "model": "deepseek-ai/DeepSeek-R1", "messages": [ {"role": "user", "content": "9.11 and 9.8, which is greater? Explain your reasoning"} ] }' Note: The REST API json output is formatted to make the output more readable. (./run_restapi_query.sh 2> /dev/null | python3 ./convert_json_2_txt.py >& run_query.out_$$) Reasoning: Okay, so I need to figure out whether 9.11 is greater than 9.8 or if 9.8 is greater. Hmm, let me start by looking at both numbers. They both have a 9 in the units place, so that part is equal. Now, I need to compare the decimal parts: .11 and .8. Wait, but decimals can be tricky because the places matter. The first number is 9.11, which has a 1 in the tenths place and a 1 in the hundredths place. The second number is 9.8, which is the same as 9.80 when you add a zero to the hundredths place for comparison. So, 9.80 versus 9.11. Now, looking at the tenths place: 8 is greater than 1. Therefore, 9.80 should be greater than 9.11. But let me double-check because sometimes when numbers have different decimal lengths, it's easy to make a mistake. If I convert both to fractions, maybe that will help. 9.11 is the same as 9 + 0.11, and 0.11 is 11/100. On the other hand, 9.8 is 9 + 0.8, which is 9 + 8/10. To compare 8/10 and 11/100, I can convert them to have the same denominator. 8/10 is equal to 80/100. Now, 80/100 is much larger than 11/100. So yes, 9.8 is indeed greater than 9.11. Another way to see it is by subtracting the two numbers. If I subtract 9.11 from 9.8, what do I get? Let's see: 9.8 - 9.11. Since 9.8 is the same as 9.80, subtracting 9.11 gives 0.69. Since the result is positive, that means 9.8 is larger. Wait, maybe I can also think about money to make it clearer. If I have $9.11 and you have $9.80, which is more? $9.80 is $9 and 80 cents, whereas $9.11 is $9 and 11 cents. Definitely, 80 cents is more than 11 cents, so $9.80 is more. That helps visualize it. Alternatively, using a number line. If I imagine a number line with 9.0, 9.1, 9.2,... up to 10.0. 9.11 is just a little past 9.1, while 9.8 is almost at 10.0. So clearly, 9.8 is much further to the right, meaning it's a larger number. I think that covers different methods: decimal place comparison, converting to fractions, subtraction, real-life money examples, and number line visualization. All of these methods point to 9.8 being greater than 9.11. I don't see any contradictions here. Maybe I can also consider writing both numbers with the same number of decimal places to make it even clearer. 9.11 is already two decimal places, and 9.8 can be written as 9.80. Now, comparing 9.80 and 9.11 digit by digit: - The units place: 9 vs. 9 (equal) - Tenths place: 8 vs. 1 (8 is greater) - Since the tenths place of 9.80 is greater, the entire number is larger, regardless of the hundredths place. So yes, that confirms it again. The key idea here is that when comparing decimals, you start from the leftmost digit after the decimal point and move right until you find a difference. In this case, the tenths place already shows that 9.8 is larger. I guess another common mistake could be thinking that because 11 is more than 8, 0.11 is more than 0.8, but that's not correct because the places are different. Tenths versus hundredths. 0.8 is equivalent to 0.80, which is way bigger than 0.11. To prevent that mistake, always align the decimal points and add trailing zeros if necessary. Then compare each digit one by one from left to right. That method avoids confusion. So, all in all, through multiple approaches, 9.8 is definitely greater than 9.11. Answer: To determine which number is greater between **9.11** and **9.8**, follow these steps: **Align the decimal places** by rewriting 9.8 as **9.80**. **Compare digit by digit** from left to right: - **Units place**: Both have **9** (equal). - **Tenths place**: **8** (in 9.80) vs. **1** (in 9.11). Since \(8 > 1\), **9.80 is greater** at this point. - No need to compare hundredths place once a difference is found. **Conclusion**: \(9.8\) (or \(9.80\)) is greater than \(9.11\) because **8 tenths** (\(0.8\)) is larger than **1 tenth + 1 hundredth** (\(0.11\)). \(\boxed{9.8 \text{ is greater}}\) Completion Info: Finish reason: stop Prompt tokens: 21 Completion tokens: 1162 Total tokens: 1183 When running using Llama 3.1 8B (Not reasoning model). Answer: To determine which is greater, we need to compare the two numbers. 9.11 is greater than 9.8 because 9.11 is a larger decimal value. Completion Info: Finish reason: stop Prompt tokens: 51 Completion tokens: 37 Total tokens: 88 Throughput and latency results Cost comparison In this cost analysis we use the ND-H100-v5 and ND-H200-v4 pay as you go pricing in south central US region and the measured total throughput tokens/sec to compute the $/(1K tokens). Note: ND-H200-v5 pricing was estimated at 20% more than ND-H100-v5 pricing. Analysis The DeepSeek R1 is a large, complex reasoning model that is costlier and slower than smaller models. It needs 16 H100 GPUs for FP8 precision and generates many more intermediate tokens in its chain of thought process—about 31 times more than Llama 3.1 8B—but at a much slower rate (~54 times slower). Its latency is also higher, with TTFT and ITL being roughly 6 and 3 times slower, respectively. The DeepSeek R1 model has small intranode and internode network requirements (~14% of available InfiniBand network bandwidth was used, and < 1% of available NVLink bandwidth is used. GPUs with higher memory bandwidth and higher FLOPS would help improve its performance. The cost analysis shows that the cost to generate DeepSeek R1 tokens is ~54 times more expensive than Llama 3.1 8B on the same 16 H100 GPU’s and ~34 times more expensive on 8 H200 GPU’s. DeepSeek R1 model is very capability, but due to its higher TCO it should be only used in specific AI applications that require its strong reasoning abilities. Conclusion The DeepSeek R1 model demonstrates exceptional reasoning capabilities, but its deployment demands substantial infrastructure and incurs high latency and cost. While it excels in generating detailed chains of thought, its throughput and efficiency lag significantly behind smaller models like Llama 3.1 8B. For applications requiring deep logical analysis, DeepSeek R1 is a powerful tool. However, for general-purpose inference tasks, more lightweight models offer better performance and cost-effectiveness. Strategic use of DeepSeek R1 should be reserved for scenarios where its advanced reasoning justifies the resource investment.

Introduction Following our previous evaluation of Llama 3.1 8B inference performance on Azure’s ND-H100-v5 infrastructure using vLLM, this report broadens the scope to compare inference performance across a range of GPU and CPU platforms. Using the Hugging Face inference benchmarker, we assess not only throughput and latency but also the cost-efficiency of each configuration—an increasingly critical factor for enterprise deployment. As organizations seek scalable and budget-conscious solutions for deploying large language models (LLMs), understanding the trade-offs between compute-bound and memory-bound stages of inference becomes essential. Smaller models like Llama 3.1 8B offer a compelling balance between capability and resource demand, but the underlying hardware and software stack can dramatically influence both performance and operational cost. This report presents a comparative analysis of inference performance across multiple hardware platforms, factoring in: Token throughput and latency across chat, classification, and code generation workloads. Resource utilization, including KV cache utilization and efficiency. Cost per token, derived from cloud pricing models and hardware utilization metrics. By combining performance metrics with cost analysis, we aim to identify the most effective deployment strategies for enterprise-grade LLMs, whether optimizing for speed, scalability, or budget. Benchmark environment Inference benchmark The Hugging face Inference benchmarking code was used for the AI Inference benchmark. Three different popular AI inference profiles were examined.

CPU performance and takeaways The Huggingface AI-MO/aimo-validation-aime data was by vllm bench to test the performance of Llama 3.1 8B on various VM types (left graph below). It is a struggle (insufficient FLOPs and memory bandwidth) to run Llama 3.1 8B on CPU VM’s, even the best performing CPU VM (HB176-96_v4) throughput and latency is significantly slower than the A100_40GB GPU. Tips Enable/use AVX512 (avx512f, avx512_bf16, avx512_vnni etc) (See what is supported/available via lscpu) Put AI model on single socket (if it has sufficient memory). For larger models you can use tensor parallel to split the model across sockets. Use pinning to specify which cores the threads will run on (in vLLM, VLLM_CPU_OMP_THREADS_BIND=0-22) Specify large enough KVCache (on CPU memory). In vLLM, VLLM_CPU_KVCACHE_SPACE=100) Analysis Throughput & Latency H200 outperforms all other GPUs across all workloads, with the highest prompt and generation throughput. H100 is a close second, showing strong performance especially in classification and code generation. A100 and A100_40G lag significantly behind, particularly in classification tasks where throughput drops by an order of magnitude (on A100_40G, due to smaller GPU memory and lower KV Cache hit percentage). KV Cache Utilization H200 and H100 show efficient cache usage with high hit rates (up to 99%) and low waiting requests. (The exception is code generation which has low hit rates (~1%)) A100_40G suffers from high KV cache usage and low hit rates, especially in classification and code generation, indicating memory bottlenecks. The strain on the inference server is observed by the higher number of waiting requests. Cost Efficiency Chat profiles: The A100 GPU (40G) offers the best value. Classification profiles: The H200 is most cost-effective. Code-generation profiles: The H100 provides the greatest cost efficiency. CPU vs GPU Llama 3.1 3B can run on CPU VM’s but the throughput and latency are so poor compared to GPU’s if does not make an practical or financial sense to do so. Smaller AI models (<= 1B parameters) may be OK on CPU’s for some light weight inference serves (like Chat). Conclusion The benchmarking results clearly demonstrate that hardware choice significantly impacts the inference performance and cost-efficiency of Llama 3.1 8B deployments. The H200 GPU consistently delivers the highest throughput and cache efficiency across workloads, making it the top performer overall. H100 follows closely, especially excelling in code generation tasks. While A100 and A100_40G offer budget-friendly options for chat workloads, their limitations in memory and cache performance make them less suitable for more demanding tasks. CPU virtual machines do not offer adequate performance—in terms of throughput and latency—for running AI models comparable in size to Llama 3.1 8B. These insights provide a practical foundation for selecting optimal infrastructure based on inference workload type and cost constraints.

Introduction The pace of development in large language models (LLMs) has continued to accelerate as the global AI community races toward the goal of artificial general intelligence (AGI). Today’s most advanced models boast trillions of parameters, pushing the boundaries of what machines can understand and generate. However, this scale comes at a steep cost—both in terms of training and inference—due to the immense GPU resources required to host and operate these models. Yet, innovation is not limited to those with access to the largest AI supercomputers. DeepSeek have demonstrated that it is possible to build highly competitive models without relying on the latest, most expensive infrastructure. At the same time, a renewed wave of open-source collaboration is challenging the closed-source strategies of leading AI companies, offering more accessible and customizable alternatives. For enterprise customers, the focus is shifting toward practical, cost-effective solutions. Rather than deploying trillion-parameter giants, many organizations are turning to smaller models—such as those with around 8 billion parameters—that strike a balance between accuracy and efficiency. These models are not only easier to fine-tune and deploy but also significantly reduce the cost per token, making them ideal for real-world business applications. In this paper, we explore the capabilities of the Llama 3.1 8B model as a representative example of a modern, enterprise-ready LLM. We benchmark its inference performance on Azure’s ND-H100 v5 infrastructure using the vLLM engine and present our findings along with recommendations for enterprise deployment. AI Inference architecture Inference in transformer-based large language models (LLMs) is typically divided into two primary stages: prefill and decode. Understanding the characteristics and resource demands of each stage is essential for optimizing performance, especially when deploying models like Llama 3.1 8B in enterprise environments. Prefill Stage: Compute-Bound Initialization The prefill stage is responsible for processing the input prompt. It involves tokenizing the input and performing a forward pass through the model to populate the key-value (KV) cache. This stage is compute-intensive, as it requires full attention computation across all input tokens. The performance bottleneck here is typically the GPU's compute throughput, especially for long prompts or large batch sizes. Decode Stage: Memory-Bound Token Generation Once the KV cache is populated, the decode stage begins. This stage generates one token at a time, using the cached context to predict the next token. The decode step is memory-bound, as it relies heavily on fast access to the KV cache. When the model achieves a KV cache hit, it can skip re-computation of earlier tokens, significantly reducing latency and compute load. This makes cache efficiency a critical factor in real-time inference performance. Fig 1. High level architecture of AI Inference, showing efficient use of KV cache can increase token throughput and reduce AI inference latency. Overall Inference Characteristics In general, AI inference is memory-bound, particularly during the decode phase. The ability to serve multiple concurrent requests efficiently depends on how well the system can manage memory bandwidth and cache locality. As such, optimizing memory access patterns and minimizing cache misses are key to achieving high throughput and low latency. Techniques for Optimization To maximize GPU utilization and token throughput while minimizing latency, several architectural strategies are employed: KV Cache Management: Efficient reuse and eviction policies to maintain high cache hit rates. vLLM uses PagedAttention (which is inspired by virtual memory and paging techniques used in operating systems), to manage the KV cache using blocks/pages. This allows vLLM to efficiently/dynamically utilize HBM memory and minimizes memory fragmentation. Batching and Scheduling: Grouping similar requests to improve parallelism and reduce idle GPU time. VLLM has a few parameters to control batching/parallelism. MAX_NUM_SEQS: How many input requests to process in parallel. MAX_NUM_BATCHED_TOKENS: The number of tokens to process in parallel (Forward pass in Deep neural network) Note: Larger values may not always be optimal; you could improve token throughput at the expense of latency. Weight and Activation Quantization (fp8): Reducing the precision of AI model weights and activations can give more memory to load AI models or have a larger KV cache. Lowering the precision also allows computations to be performed on more efficient GPU (higher FLOPS) computational units. Parallelization techniques: Tensor parallelism, Pipeline parallelism, Expert parallelism or Data parallelism can be used to split larger models across multiple Nodes/GPUs. Tensor parallelism distributes the model across the GPUs, with each GPU handling multiple layers of the model. Pipeline parallelism involves dividing the model, where a group of nodes (or GPUs) is responsible for processing its assigned DDN layer. Expert parallelism supports Mixture of Experts (MoE) models where different expert networks can be distributed across GPU’s. Data parallelism replicates the entire model across multiple GPU sets and processes different batches of requests in parallel Speculative Decoding: Predicting multiple tokens ahead to reduce the number of forward passes. Prefill/Decode Decoupling: Recent advancements, such as those implemented in vLLM (and NVIDIA Dynamo), decouple the prefill and decode stages, allowing each to be assigned dedicated GPU or CPU resources. This separation enables better resource allocation and parallelism, especially in multi-tenant or high-throughput environments. By leveraging these techniques, vLLM provides a highly efficient inference engine that is well-suited for serving modern LLMs like Llama 3.1 8B. This makes it a compelling choice for enterprise applications where cost, latency, and scalability are critical considerations.

Fig 4: Code generation inference benchmark run on 1 H100 showing the performance impact of using fp8 quantization. Fig 5: Code generation benchmark run on 1, 2, 4 & 8 H100. The results indicate that higher token throughput could be achieved running inference using 1 copy of model on each GPU instead of distributing model (via tensor parallel) amongst the 8 GPUs. Fig 6: Impact on throughput (tokens/sec) by adjusting AI Inference configuration (vLLM) on ND-H100-v5. Results comparing Dynamo vs traditional vLLM Fig 7: Dynamo vs traditional vLLM throughput (tokens/sec) comparison on 1 ND_H100_v5 (8 GPU’s). The best traditional vLLM configuration (8 x vLLM tensor_parallel=1) throughput performance is compared with various Dynamo configurations (i.e different combinations of GPU’s assigned for decode and prefill). Note: vLLM does have an experimental disaggregated prefill capability with various connector types. I attempted to run vLLM experimental disaggregated prefill using the kv-connector = LMCacheConnectorV1 (with Nixl enabled). I got mixed results, eventually running into the following issues (and deciding to switch to Nvidia Dynamo instead). Limited control over allocating GPU’s to decode vs prefill (used tensor parallel option, but limited by specific ratio with number of attention multi-heads). Memory management problems, got OOM errors even though there was plenty of HBM memory available on GPU’s (HBM was not distributed evenly amongst GPU’s). Analysis The performance of the inference prefill is determined by length and number of input prompts, this phase is compute bound (effectively a Matrix-Matrix operation) and we see that the code-generation profile does best primarily because it had the largest number of input tokens. The decode phase is a memory bound operation (effectively a Vector-Matrix operation) and performance in this phase is heavily dependent on the KV cache hit percentage. The code-generation profile only had ~1.7% KV cache hit percentage (there was plenty of HBM capacity, only ~10% of available KV Cache capacity was used), which resulted in slow decode performance impacting its overall throughput and latency especially at higher QPS (the code-generation benchmark was the only one which had requests being backed-up and waiting). The classification profile did well in the decode phase primarily due to the high KV cache hit percentage (~100%), it did struggle in overall throughput due to the small length of the output tokens. Adjusting the size of MAX_NUM_BATCHED_TOKENS had very little impact on the chat and classification benchmarks probably because they had high KV Cache hit percentages, but it did impact the performance of the code-generation benchmark (a ~3% improvement in tokens/sec using a larger value). Quantization of AI model can free up HBM memory to allow a large model to load or improve the AI inference performance by providing more memory for KV caching, it can also improve performance by performing computations with a higher FLOPS lower precision (e.g. FP8) format. In this case there is plenty of HBM and all three profiles did not use all the available KV cache space available, so FP8 quantization does not improve KV caching efficiency. Improvements in compute performance are observed with quantization, especially for the code generation profile which had a low KV cache hit percentage. The code generation tokens/sec on 1 GPU improved by ~38%. Since the Llama 3.1 8B model can easily fit on 1 H100, you can get significantly better total throughput (tokens/sec) on ND-H100-v5 if a complete model is loaded into each separate GPU instead of splitting the model across multiple GPU’s (via tensor parallel). The chat, classification and code generation inference throughput improved 4.2, 5.2, 1.9 times respectively. Newer inferencing server architectures feature disaggregated prefill, which allows you to decouple prefill from decode and assign resources (GPU’s, CPU’s) to each type of worker (prefill or decode). This is especially suited for large reasoning models with large context windows, running on large GPU inference clusters, significant performance gains have been reported. In this case we have a modest size (8B parameters) NLP model running on a single ND_H100_v5 node (only 8 GPU’s), so we were not expecting any significant performance improvements. The traditional aggregated vLLM was much faster than the best Dynamo configuration, running this inference benchmark on llama 3 8B model on ND_H100_v5. In this case the model can fit in a single GPU and the overhead of disaggregation might outweigh any parallelism gains when one GPU can already handle both phases efficiently. Conclusions When analyzing the performance of AI inference, it’s important not only to focus on the number of input and output tokens but also on the type of AI inference application, which can have a big impact on KV Cache effectiveness. Smaller AI models provide opportunities and more options to configure your environment in an optimal way to maximize token/sec throughput.

Small performance gaps on a single virtual machine lead to large and costly performance losses at scale. Running small-scale pretraining jobs enables single-VM validation and allows for fine-grained identification of issues such as performance degradation, hardware bottlenecks, or software inefficiencies ahead of large-scale runs. In this post, we present a practical methodology for benchmarking the ND GB200 v6 virtual machines (VMs). A single ND GB200 v6 VM on Azure is powered by two NVIDIA Grace CPUs and four NVIDIA Blackwell GPUs. To ensure reliability in production workloads we used automated pretraining of lightweight Llama models with the NVIDIA NeMo framework. By systematically exploring and tuning key performance parameters and rigorously cross-checking results with detailed telemetry, we identify conditions that most significantly stress the GPUs. You can reproduce and reuse these pretraining workloads from our fully automated Azure AI Benchmarking guide.
Ansys Minerva Simulation & Process Data Management Architecture on Azure
Architecture Ansys Minerva baseline architecture has four distributed tiers (client, web, enterprise, and resource) in a single Azure availability zone. Each tier aligns to function and communication flows between these tiers. All four tiers use their own virtual machines in a single virtual network. The Minerva core business functionality runs on a central core server in the enterprise tier and users access it through a web-based url client. You can deploy multiple instances in Dev and Test environments on virtual machines and storage on Dev/Test virtual networks separate from production virtual networks. Workflow SPDM users access the Minerva application via HTTPS-based endpoint Public URL. Users access the application through the web URL via internet. Azure Entra ID with SAML configuration allows single sign on authentication to the Minerva application. User is authenticated using a Minerva credential that a Minerva administrator creates in Minerva. Azure Firewall Azure backbone component which filters traffic and threat intelligence feeds directly from Microsoft Cyber Security. Https traffic directed to the Azure Application gateway. The Hub virtual network and spoke virtual network are peered to communicate over the Azure backbone network. Azure Application Gateway routes traffic to Minerva’s web server virtual machines (VMs) in the Web tier. Azure Application Gateway with Web Application firewall inspects the incoming Http traffic to continuously monitor Minerva against exploits. Seamlessly integrates with other Azure services (App Service, VMSS, AKS, etc.), making it easier to build cloud-native solutions. Application Gateway supports sticky sessions for applications that require session persistence. Web tier subnet: Users access the core component of Minerva via Web tier running IIS application server. To ensure consistent and reliable performance for your application, all virtual machines should have the recommended VM size, disk configuration. Depending on your needs, you may want to use HPC (High Performance Computing) VM SKUs. Make sure all VM instances are created from the same base OS image and configuration. The Enterprise subnet runs the following core Minerva components: Individual user access is granted based on valid Minerva and Aras Innovator feature licenses. These feature licenses are separate from the Aras Innovator server licenses. Enterprise tier VMs run the core business logic components of Minerva. These components include Minerva Simulation Product Data Management- core server, Agent server, Vault server, Meta data extraction server & license servers. Core components: Minerva ‘s central processing server is IIS application server. Agent server runs the agent services that are responsible for various platform orchestration activities. All the core components must be deployed in Azure proximity placement group to minimize the latency. Distributed components: Vault server and Meta data extraction server. Vault server stores the files, paired with other servers dedicated to processing Meta data extraction. An IIS Web Server acts as a frontend to the file repository There can be any number of Data Vaults distributed throughout the organization, based upon specific needs and criteria, and all Vaults communicate with the centralized Core Components. Scope of the Minerva vault server can be expanded to interact with any HPC cluster. Extraction server: Metadata Extraction is very memory, processor, and disk intensive, potentially opening large files. Sufficient capacity for Azure virtual machines or storage is required for this activity. SKU recommendation is given below. MS SQL Server: You can deploy the SQL server standard or enterprise version based on your company’s requirements. Minerva SQL server stores metadata objects only and no binary files are stored in the database. Database subnet runs a SQL Server database using an infrastructure-as-a-service deployment. It uses SQL Server Always On availability groups for asynchronous replication. Minerva deployment could run an Oracle Database server on this IAAS deployment. Storage subnet uses Azure Files Premium and/or Azure NetApp Files. On-premises network allows the customer support team and system administrators to connect to Azure via Azure VPN connection to gain access to any virtual machine instances via Remote Desktop Protocol (RDP) from Azure Bastion. Minerva Core Component & Vault reliability Use multiple VMs in web tier. To enhance resiliency and scalability of the Ansys Minerva application running on Azure distributes the four logical tiers across multiple virtual machines. It is recommended to run multiple parallel web servers for either load balancing and/or increased reliability. Use multiple VMs in Enterprise tier. You should install the Enterprise tier on multiple Azure virtual machines. This setup ensures fail-over support and enables load balancing to optimize performance. Application gateway load balances between VMs in the Web subnet web servers. By distributing software functions over a network, the application can achieve high availability and improve overall system reliability. This configuration is particularly beneficial for production environments where uninterrupted operation and efficient resource utilization are crucial. With the ability to distribute the workload across multiple virtual machines, the Minerva application can handle increased demand and provide a robust and responsive user experience. By following this recommended architecture, you can leverage the scalability and resilience capabilities of Azure to optimize the performance of Ansys Minerva application. It helps ensure uninterrupted access to critical product lifecycle management functionalities. Resource tier reliability Configure database backups. For SQL Server, one approach is to use Azure Backup using Recovery Services Vault to back up SQL Server databases that run on VMs. With this solution, you can perform most of the key backup management operations without being limited to the scope of an individual vault. For more information on Oracle, see Oracle Database in Azure Virtual Machines backup strategies. Use the native backup utility. It’s recommended to use the Azure backups. When performing server-level backups, you should avoid backing up the active database files directly. This is because the backup may not capture the complete state of the database files at the time of backup. Instead, server-level backups should focus on backing up the backup file generated by using the database backup utility. This approach ensures a more reliable and consistent backup of the application's database. By following this recommendation, you can effectively protect the integrity and availability of your Minerva application data, safeguarding critical information and enabling efficient recovery in case of any unforeseen issues or data loss. Configure volume backups. Azure Files provides the capability to take snapshots of file shares, creating point-in-time, read-only copies of your data. By using Azure Files or Azure NetApp Files snapshots, establish a general-purpose backup solution that safeguards against accidental deletions or unintended changes to the data. For the Minerva volume server, use File volume backups. This configuration ensures effective backup of the data stored in the volume server, enabling easy recovery in case of data loss or system failures. Implementing these recommendations enhances the data protection and resilience of the Minerva application, mitigating the risks associated with data loss or unauthorized modifications. Test database and storage backups. You should carefully plan, document, and test the backup and recovery strategy for the Minerva database and file manager servers. Configure backup frequency. Determine backup needs based on business requirements, considering the increasing number of users. A daily backup may not be sufficient for optimal protection, so adjust the frequency accordingly. Coordinate volume data with database backups. Ensure that backups for the volume servers are coordinated with database backups. This allows you to sync the actual files with the file metadata. Enhance database reliability. Provision SQL Server VMs in Availability Sets to improve database reliability. Availability Sets deploy virtual machines across fault domains and update domains, mitigating downtime events within the datacenter. Create an availability set during VM provisioning. Additionally, consider replicating Azure storage across different Azure datacenters for additional redundancy. For Oracle databases, Azure offers availability zones and availability sets. You should only use availability sets in regions where availability zones are unavailable. In addition to Azure tools, Oracle provides Oracle Data Guard and Goldengate solutions. Use Always On availability group. Configure the database server with an "Always On" availability group for SQL Server on Azure Virtual Machines. This option uses the underlying Windows Server Failover Clustering (WSFC) service and helps ensure high availability. For more information, see Overview of SQL Server Always On availability groups and Windows Server Failover Clustering (WSFC). Security Azure Security provides assurances against deliberate attacks and the abuse of your valuable data and systems. For more information, see Overview of the security pillar.

Microsoft Azure’s high-performance computing (HPC) & AI infrastructure is designed from the ground up to support the world’s most demanding workloads. High-performance AI workloads are bandwidth-hungry and latency-sensitive. As models scale in size and complexity, the efficiency of the interconnect fabric—how CPUs, GPUs, and storage communicate—becomes a critical factor in overall system performance. Even with the fastest GPUs, poor interconnect design can lead to bottlenecks, underutilized hardware, and extended time-to-results. In this blog post, we will highlight one of the key enabling features for running large-scale distributed workloads on Azure: a highly tuned HPC-class interconnect. Azure has invested years of system-level engineering of the InfiniBand interconnect, into ready-to-use configurations for customers available on Azure’s HB-series and N-series virtual machine (VMs).Announcing Azure HBv5 Virtual Machines: A Breakthrough in Memory Bandwidth for HPC
