The first half of 2023 has been quite prolific for the Dell Azure Stack HCI ecosystem, providing many important incremental updates in the platform. This article summarizes the most relevant changes inside the program.
Azure Stack HCI
Dell Integrated System for Microsoft Azure Stack HCI delivers a fully productized, validated, and supported hyperconverged infrastructure solution that enables organizations to modernize their infrastructure for improved application uptime and performance, simplified management and operations, and lower total cost of ownership. The solution integrates the software-defined compute, storage, and networking features of Microsoft Azure Stack HCI with AX nodes from Dell to offer the high-performance, scalable, and secure foundation needed for a software-defined infrastructure.
With Azure Arc, we can now unlock new hybrid scenarios for customers by extending Azure services and management to our HCI infrastructure. This allows customers to build, operate, and manage all their resources for traditional, cloud-native, and distributed edge applications in a consistent way across the entire IT estate.
What’s new with Azure Stack HCI?
A lot. There have been so many updates in the Azure Stack HCI front that it is difficult to detail all of them in just a single blog. So, let’s focus on the most important ones.
Azure Stack HCI software and hardware updates
From a software and hardware perspective, the biggest change during the first half of 2023 was the introduction of Azure Stack HCI, version 22H2 (factory install and field support). The most important features in this release are Network ATC, GPU partitioning (GPU-P), and security improvements.
- Network ATC simplifies the virtual network configuration by leveraging intent-based network deployment and incorporating Microsoft best practices by default. It provides the following advantages over manual deployment:
- Reduces network configuration deployment time, complexity, and incorrect input errors
- Uses the latest Microsoft validated network configuration best practices
- Ensures configuration consistency across all nodes in the cluster
- Eliminates configuration drift, with periodic consistency checks every 15 minutes
- GPU-P allows sharing a physical GPU device among several VMs. By leveraging single root I/O virtualization (SR-IOV), GPU-P provides VMs with a dedicated and isolated fractional part of the physical GPU. The obvious advantage of GPU-P is that it enables enterprise-wide utilization of highly valuable and limited GPU resources.
- Azure Stack HCI OS 22H2 security has been improved with more than 200 security settings enabled by default within the OS (“Secured-by-default”), enabling customers to closely meet Center for Internet Security (CIS) benchmark and Defense Information System Agency (DISA) Security Technical Implementation Guide (STIG) requirements for the OS. All these security changes improve the security posture by also disabling legacy protocols and ciphers.
From a hardware perspective, these are the most relevant additions to the AX node family:
- More NIC options:
- Mellanox ConnectX-6 25 GbE
- Intel E810 100 GbE; also adds RoCEv2 support (now iWARP or RoCE)
- More GPU options for GPU-P and Discrete Device Assignment (DDA):
- GPU-P validation for: NVIDIA A40, A16, A2
- DDA options: NVIDIA A30, T4
To better understand GPU-P and DDA, check this blog.
Azure Stack HCI End of Life (EOL) for several components
As the platforms mature, it is inevitable that some of the aging components are discontinued or replaced with newer versions. The most important changes on this front have been:
- EOL for AX-640/AX-740xd nodes: Azure Stack HCI 14G servers, AX-640, and AX-740xd reached their EOL on March 31, 2023, and are therefore no longer available for quoting, or new orders. These servers will be supported for up to seven years, until their End of Service Life (EOSL) date. Azure Stack HCI 15G AX-650/AX-750/AX-6515/AX-7525 platforms will continue to be offered to address customer demands.
- EOL for Windows Server 2019: While Windows Server 2019 will be reaching end of sales/distribution from Dell on June 30, 2023, the product will continue to be in Microsoft Mainstream Support life cycle until January 9, 2024. That means that our customers will be eligible for security and quality updates from Microsoft free of charge until that date. After January 9, 2024, Windows Server will enter a 5-year Extended Support life cycle that will provide our customers with security updates only. Any quality and product fixes will be available from Microsoft for a fee. It is highly recommended that customers migrate their current Windows Server 2019 workloads to Windows Server 2022 to maintain up-to-date support.
Finally, we have introduced a set of short and easily digestible training videos (seven minutes each, on average) to learn everything you need to know about Azure Stack HCI, from the AX platform and Microsoft’s Azure Stack HCI operating system, to the management tools and deploy/support services.
Conclusion
It’s certainly a challenge to synthesize the last six months of incredible innovation into a brief article, but we have highlighted the most important updates: focus on learning all the new Azure Stack HCI 22H2 features and updates, keep current with the hardware updates, and… stay tuned for important announcements by the last quarter of the year: big things are coming in Part 2!!!
