Uncover the benefits of Microsoft Azure Stack HCI on newly certified Lenovo ThinkSystem V3 servers based on 4th Generation AMD EPYC “Genoa” processors.

Accelerate Your Business

Deploying hyperconverged infrastructure (HCI) has become the de-facto standard for organizations looking to modernize their aging infrastructure. Large storage deployments are increasingly being replaced by HCI based solutions for most general-purpose workloads. HCI has proven to deliver better efficiency and price performance in the datacenter. Additionally, customers have been choosing a hybrid approach, migrating certain workloads to the cloud, while keeping other workloads on-premises.

Azure Stack HCI is Microsoft’s HCI solution for customers that wish to run workloads on-premises and extend easily to Azure for hybrid capabilities such as back-up, site recovery, storage, cloud-based monitoring and more. Microsoft Azure Stack HCI with Azure Arc on Lenovo servers provides consistent management across the hybrid cloud solution and enables extension of the hybrid cloud to the edge.

Azure Stack HCI is a new HCI host operating system from Microsoft, delivered as an Azure service, providing the latest and up-to-date security, performance, and feature updates. Azure Stack HCI builds on the foundation of the Microsoft Windows Server Software Defined program and provides a certification path for Storage Spaces Direct solutions.

Lenovo has designed, tested, and validated ThinkSystem SR665 V3, SR655 V3, SR645 V3 and SR635 V3 Azure Stack HCI validated nodes to enable the quick deployment of a robust, high-performance hybrid cloud solution and rapidly solve your IT challenges.

Reliability: Powered by Lenovo Servers

The Lenovo ThinkSystem SR635 V3 and the SR655 V3 servers are 1-socket servers in 1U and 2U rack form factors respectively that feature the AMD EPYC 9004 family of processors. With up to 128 processor cores and support for the new PCIe 5.0 standard for I/O, these servers offer the ultimate in one-socket server performance.

The Lenovo ThinkSystem SR645 V3 and the SR665 V3 servers are 2-socket servers in 1U and 2U rack form factors respectively that feature the AMD EPYC 9004 family of processors. With up to 128 processor cores and support for the new PCIe 5.0 standard for I/O, these servers offer the ultimate in two-socket server performance.

Modern IT applications like AI, software-defined and virtualization applications utilize a vast amount of data to operate seamlessly and require servers with the next era of solution performance and flexibility.

The new ThinkSystem SR6x5 V3 servers provide the performance to manage these next gen applications. With the 4th Generation AMD EPYC™ processors, up to 160 PCIe gen5 lanes for I/O speed, the latest TruDDR5 memory, and multiple drive options for agile storage, the SR6x5 V3 servers have the performance to tackle the complex workloads of today and tomorrow.

In addition to high performance, Lenovo ThinkSystem servers consistently rank high in customer satisfaction and have been rated #1 in x86 server reliability for 9 years running1.

Excellent Value

Lenovo Azure Stack HCI offerings use the Microsoft Azure Stack HCI operating system on the host nodes, and optionally include Windows Server 2022 Datacenter in case you require unlimited guest OS virtual machine licenses. The Azure Stack HCI OS license provides the following benefits:

  • Storage Spaces Direct (S2D): State of the art software-defined storage from Microsoft with multiple high-performance resiliency options, deduplication, compression and more.
  • Windows Admin Center (WAC): A web-based management portal is included with the software at no extra cost. Deployment and update features in WAC make deployment extremely simple and easy to perform. Additionally, Lenovo’s XClarity plugin allows you to deploy hardware as well as software from the same interface, enabling a single pane of management. Cluster-aware updating features make it easy to streamline software and firmware updates in a single maintenance window.
  • Hyper-V: Hypervisor is included in the license
  • Software-Defined Networking: Features such as virtual network encryption, firewall auditing, and virtual network peering allow you to get the benefits of a more secure software defined network with Azure Stack HCI.
  • Azure Stack HCI is hybrid by design, and you can benefit from native integration with Azure ARC and Azure Monitor and connect to Azure for a variety of Azure hybrid services seamlessly. Fleet management for hosts and VMs allows you to monitor and manage clusters at scale.
  • The Extended Security Update (ESU) program enables you to get important security patches for legacy Microsoft products that are past the end of support. There are several advantages to getting ESU through Azure, which extend to Azure Stack HCI:
    • Free of charge: You can get ESUs through Azure Stack HCI for free.
    • Get an additional year of ESUs for Windows Server and SQL Server 2008 and 2008 R2: On Azure and Azure Stack HCI only, ESUs for Windows Server and SQL Server 2008 and 2008 R2 will end on January 14, 2024 and July 12, 2023 respectively; a year longer than the usual three-year ESU programs.
    • Windows Server 2012 and Windows Server 2012 R2 will end on October 10, 2023. If your servers are on-premises or in a hosted environment, you can enroll your Windows Server 2012 and 2012 R2 or SQL Server 2012 machines for Extended Security Updates via the Azure portal, connect through Azure Arc, and you'll be billed monthly via your Azure subscription.

Azure Arc

Microsoft Azure Arc is a set of technologies that allows customers to view and manage both their on-premises and cloud resources with a single pane of glass. With Azure Arc you can manage both your VMs in Azure and VMs on-premises, apply security policies to both and provide tough governance easily through a self-service portal.
