đ˘ [Public Preview] Accelerating BlobNFS throughput & scale with FUSE for superior performance
Azure Blob Storage can be mounted and accessed like a local file system using BlobFuse, which is a FUSE-based driver for the Blob REST API. Customers choose BlobFuse for AI/ML, HPC, analytics and backup workloads. It provides exceptionally high throughput along with benefits like local caching and security integration via Azure Entra ID. For customers requiring NFS 3.0 protocol support or POSIX compliance, Azure Blob Storage also natively supports NFSv3 (aka BlobNFS). It enables Azure Blob storage access for customersâ legacy applications without requiring changes. BlobNFS is accessed via the Linux NFS client combined with our AZNFS mount helper package, which streamlines mounting and reliably connecting to Blob Storageâs NFS endpoints. Please note that BlobNFS only supports access over a virtual network since Azure Entra ID based auth isnât yet available on NFS 3.0. Today, weâre excited to announce an update to AZNFS (3.0) for BlobNFS, which now uses the same libfuse3 library that powers BlobFuse bringing significant improvements in performance and scale. The updated AZNFS for BlobNFS delivers significantly higher throughput, larger file support, better metadata performance, and removes user group limits, enhancing performance for demanding workloads. Maximize Virtual Machine throughput: AZNFS now supports up to 256 TCP connections (up from16 in native NFS client) allowing throughput to reach VM NIC bandwidth (the maximum data transfer rate of virtual machineâs network interface card) or storage account limits. This benefits HPC workloads by ensuring high throughput for large dataset operations. Additionally, a small number (4 or fewer) of parallel file reads/writes can now fully saturate the VM NIC bandwidth even for larger VM sizes. Enhanced read/write speed: The updated AZNFS client outperforms native NFS client for read and write scenarios. For example, single file read/write performance is improved by a factor of 5x and 3x respectively, which can be useful for large database backup tasks requiring high single file throughput for writing and reading backup files. Refer to the link for a detailed performance comparison. Removal of the user's group limit: Linux NFS clients with a local Identity server can pass access permissions for up to 16 groups of a user, restricting resource access for users belonging to more than 16 groups. This update allows FUSE to handle permission checks, removing the 16-group limitation. Improved metadata query performance: READDIR can query more directory entries in one call. The Linux client has a limit of 1MB, whereas the updated AZNFS can now reach up to 3 MB. Customers with numerous files will experience quicker listing and metadata operations with reduced latency. This will be beneficial for workloads like EDA (Electronic Design Automation) and HPC (High Performance Computing) which often involve reading metadata for considerable number of files before selecting a subset for processing. Support for large file sizes (up to 5TB): The new release can support larger file sizes for sequential write patterns. Due to larger block sizes possible with AZNFS, users can create larger files up to the 5TB limit. With Linux clients, under best conditions, the max. file sizes were limited to ~3TB. CAD tools producing simulation and checkpoint data files over 3TB will benefit from this improvement. The following charts compare performance between updated AZNFS and the Native Linux client. Please refer the detailed benchmarks for more details. [Test parameters - VM: Standard D96ds v5, File size: 100GB, Linux NFS is with nconnect =16, Linux kernel 5.x.x ; Test used: DD test] Note: The VM supports higher read throughput than write throughput. For updated AZNFS, throughput starting from 4 parallel file read/write operations is constrained by VM NIC bandwidth, or it can scale higher.

For those who missed the last announces of Azure end of life, please find a small recap: Azure AI Intelligence The Azure AI Document Intelligence API v2.0 will be retired on August 31, 2026. You are simply encouraged to migrate to the same API but in version 3.1 which obviously offers more features than the previous one. Azure AI Video Indexer Due to the withdrawal of Azure Media Services, announced during the month of July, Microsoft has decided to remove all dependencies related to Azure Media from Azure AI Video Indexer, starting January 15, 2024. Azure FarmBeats The Azure FarmBeats project will be retired on September 30, 2023. For those who are not familiar with Azure FarmBeats, it is a solution that allows you to aggregate agricultural datasets from different providers. Instead, Microsoft offers Azure Data Manager for Agriculture, which is actually an enhanced version of the Azure FarmBeats project. Azure HPC Azure FXT Edge Filer which is a caching appliance for HPC computing tasks will be retired on December 31, 2026. However, no information on a possible service which will replace it. Azure Kubernetes Service The AKS product team has decided to remove Azure Monitor for AKS-Engine on September 14, 2026. You are therefore encouraged to use Azure Monitor for Containers functionality instead. We continue with another decommission on AKS which concerns the HTTP application routing add-on module, which will be deleted on March 3, 2025. Please note that this module is no longer supported since version 1.22 of K8S. Instead, you are encouraged to use the Web Application routing add-on. Azure Sphere The Classic version of Azure Sphere CLI will be decommissioned on September 30, 2024. No worries here for its replacement which is none other than Azure Sphere CLI. Azure Database for MariaDB End of life of Azure Database for MariaDB which will be retired on September 19, 2025. Microsoft therefore suggests that you use Azure Database for MySQL instead which offers more features. Azure Monitor The removal of the Data Collector API that manages custom log ingestion into Azure Monitor logs will be done on September 14, 2026. Before this date, you will need to migrate to the rules-based log ingestion API which provides all the functionality of the Data Collector API, plus some new features. On September 30, 2026 the "Classic" URL Ping Tests configured on Application Insights will be deleted, in favor of the "Standard" tests. Azure Storage The product team announced for September 13, 2024 the removal of the old Azure Storage Python client libraries, but also the Azure Storage Ruby client libraries, as well as the old Azure Storage Go client libraries. Instead you will have to use the new libraries. Azure Maps The product team announces that the Azure Maps Data V1/V2 APIs will be retired on September 16, 2024. Instead, Azure Maps has deployed Data Registry APIs that provide enhanced data security. Azure Maps Render V1 APIs will be retired on September 17, 2026. You are therefore encouraged to migrate or deploy Azure Maps Render V2 APIs, which provide improved data quality and performance compared to the previous version. The Azure Maps Gen1 pricing tier will no longer exist from September 15, 2026. You will therefore need to upgrade to the Azure Maps Gen2 pricing tier which offers simplified pricing and better flexibility.Azure HPC Cache Updates: New Caching Option, Discounted Pricing, and More!

Additional details on priming will be included in our next blog post. Lower Pricing for Azure HPC Cache - Standard While it seems like the cost of everything is going up, weâre happy to report a price drop. As part of our commitment to provide the most cost-effective performance cache, weâre excited to share that we have dropped Azure HPC Cache â Standard prices by up to 33% percent in some regions. The new pricing is effective immediately. This enables cost-conscious verticals like media and entertainment to meet strict rendering deadlines while spending less on caching. Life sciences customers who rely on grants to fund their genomics research can now stretch their funds further. And chip designers can run their EDA workloads at a lower cost and still maintain the high performance for their tools repositories that theyâve come to expect. Terraform Terraform, an open-source software tool created by HashiCorp, provides an orchestration layer to deploy Azure resources. Using Terraform, you can deploy your own vdbench test system with all the required resources to run a performance benchmark. To try this yourself, the HPC Cache team has created a vdbench NFS-backed storage cache Terraform recipe to deploy a Premium 5G cluster and 30 clients. You can additionally run your own benchmarks against a 5G storage cache. Instructions and examples can be found on HPC Cache GitHub. ââ
