Azure Stack HCI 解决方案概述Azure Stack HCI solution overview

Azure Stack HCI 是一种超融合群集解决方案,它在混合的本地环境中运行虚拟化的 Windows 和 Linux 工作负载。Azure Stack HCI is a hyperconverged cluster solution that runs virtualized Windows and Linux workloads in a hybrid on-premises environment. Azure 混合服务通过基于云的监视、站点恢复和 VM 备份等功能,以及 Azure 门户中所有 Azure Stack HCI 部署的中心视图增强群集。Azure hybrid services enhance the cluster with capabilities such as cloud-based monitoring, Site Recovery, and VM backups, as well as a central view of all of your Azure Stack HCI deployments in the Azure portal. 你可以使用现有工具(包括 Windows Admin Center、System Center 和 PowerShell)管理群集。You can manage the cluster with your existing tools including Windows Admin Center, System Center, and PowerShell.

Azure Stack HCI 版本 20H2 是全新的操作系统,现在有公共预览版并可供下载Azure Stack HCI, version 20H2 is a new operating system now in Public Preview and available for download. 它适用于运行虚拟化工作负载且内置混合云连接的本地群集。It's intended for on-premises clusters running virtualized workloads, with hybrid-cloud connections built-in. 因此,Azure Stack HCI 作为 Azure 服务交付,并根据 Azure 订阅计费。As such, Azure Stack HCI is delivered as an Azure service and billed on an Azure subscription. Azure Stack HCI 现在还具备托管 Azure Kubernetes 服务的功能;有关详细信息,请参阅 Azure Stack HCI 上的 Azure Kubernetes 服务Azure Stack HCI also now includes the ability to host the Azure Kubernetes Service; for details, see Azure Kubernetes Service on Azure Stack HCI.

有关详细信息,请参阅准备工作For more information, see Before you begin. 关于 Azure Stack HCI 上的 Azure Kubernetes 服务的要求,请参阅 Azure Stack HCI 上的 AKS 要求For Azure Kubernetes Service on Azure Stack HCI requirements, see AKS requirements on Azure Stack HCI.

硬件合作伙伴Hardware partners

你可以从首选 Azure 合作伙伴处购买经过验证的 Azure Stack HCI 解决方案,从而不需要经过长时间的设计和构建就能启动和运行。You can purchase validated Azure Stack HCI solutions from your preferred Azure partner to get up and running without lengthy design and build time. Azure 合作伙伴还可提供单一联络点来帮助你完成服务的实施与支持。Azure partners also offer a single point of contact for implementation and support services. 你可以购买经过验证的节点或集成系统,其中包括预安装的 Azure Stack HCI 操作系统以及用于驱动程序和固件更新的合作伙伴扩展。You can either purchase validated nodes or an integrated system, which includes the Azure Stack HCI operating system pre-installed as well as partner extensions for driver and firmware updates.

软件合作伙伴Software partners

有很多 Azure 合作伙伴开发的软件可扩展 Azure Stack HCI 功能,同时还让 IT 管理员能够使用熟悉的工具。There are a variety of Azure partners working on software that extends the capabilities of Azure Stack HCI while allowing IT admins to use familiar tools. 例如,全球备份解决方案提供商和 Azure 金牌合作伙伴 Altaro 已承诺在 Altaro VM 备份解决方案中支持 Azure Stack HCI。For example, Altaro, a worldwide provider of backup solutions and Azure Gold Partner, has committed to supporting Azure Stack HCI in its Altaro VM Backup solution. 这样,客户和托管服务提供商在 2021 年 6 月底之前,都可以免费备份在 Azure Stack HCI 上运行的虚拟机。This will allow customers and managed service providers to back up virtual machines running on Azure Stack HCI for free until end of June 2021. 详细了解此公告Learn more about this announcement.

许可、计费和定价Licensing, billing, and pricing

Azure Stack HCI 计费基于每个物理处理器核心(而不是永久许可证)的每月订阅费用。Azure Stack HCI billing is based on a monthly subscription fee per physical processor core, not a perpetual license. 当客户连接到 Azure 时,所使用的核心数量会自动上传并进行评估,以进行计费。When customers connect to Azure, the number of cores used is automatically uploaded and assessed for billing purposes. 成本不会因使用超出物理处理器核心而变化,这意味着更多的 VM 并不会花费更多成本,能够运行更密集的虚拟环境的客户会得到奖励。Cost doesn't vary with consumption beyond the physical processor cores, meaning that more VMs don't cost more, and customers who are able to run denser virtual environments are rewarded.

客户可以从预安装了 Azure Stack HCI 操作系统的硬件合作伙伴处购买经过验证的服务器,或者从 OEM 购买经过验证的裸机服务器,然后订阅 Azure Stack HCI 服务并从 Azure 门户下载 Azure Stack HCI 操作系统。Customers can either purchase validated servers from a hardware partner with the Azure Stack HCI operating system pre-installed, or they can buy validated bare metal servers from an OEM and then subscribe to the Azure Stack HCI service and download the Azure Stack HCI operating system from the Azure portal.

  • 关联和反关联规则:它们可用于将 VM 和存储放在一起或分开放在具有多个容错域的群集中,例如延伸群集。Affinity and anti-affinity rules: These can be used to keep VMs and storage together or apart in clusters with multiple fault domains, such as stretched clusters.
  • Azure 门户集成:Azure Stack HCI 的 Azure 门户体验旨在查看全球范围内的所有 Azure Stack HCI 群集以及正在开发中的新功能。Azure portal integration: The Azure portal experience for Azure Stack HCI is designed to view all of your Azure Stack HCI clusters across the globe, with new features in development.
  • 高性能工作负荷的 GPU 加速:AI/ML 应用程序可以从使用 GPU 提高性能中获益。GPU acceleration for high-performance workloads: AI/ML applications can benefit from boosting performance with GPUs.
  • BitLocker 加密:你现在可以使用 BitLocker 对 Azure Stack HCI 上的数据卷内容进行加密,帮助政府和其他客户遵守 FIPS 140-2 和 HIPAA 等标准。BitLocker encryption: You can now use BitLocker to encrypt the contents of data volumes on Azure Stack HCI, helping government and other customers stay compliant with standards such as FIPS 140-2 and HIPAA.
  • 提高了存储空间直通卷的修复速度:快速、无缝地修复卷。Improved Storage Spaces Direct volume repair speed: Repair volumes quickly and seamlessly.

Windows Admin Center 版本 20H2 还为基于 Windows Server 的群集提供了新的群集更新 UI,包括原始的 Azure Stack HCI 解决方案。Windows Admin Center, version 20H2 also provides new cluster updating UI to Windows Server-based clusters, including the original Azure Stack HCI solutions. 虽然你可以在 Windows Server 上使用新群集创建向导,但它不能使用存储空间直通创建 Windows Server 群集;需要使用 Azure Stack HCI 操作系统。And while you can use the new cluster creation wizard with Windows Server, it can't create Windows Server clusters with Storage Spaces Direct; you need the Azure Stack HCI operating system for that.

无需虚拟化即可运行的角色Roles you can run without virtualizing

由于 Azure Stack HCI 旨在作为虚拟化主机,供你在虚拟机中运行所有工作负载,因此 Azure Stack HCI 术语允许只运行托管虚拟机所需的内容。Because Azure Stack HCI is intended as a virtualization host where you run all of your workloads in virtual machines, the Azure Stack HCI terms allow you to run only what's necessary for hosting virtual machines.

这意味着你可以运行以下服务器角色:This means that you can run the following server roles:

  • Hyper-VHyper-V
  • 软件定义网络 (SDN) 所需的网络控制器和其他组件Network controller and other components required for Software Defined Networking (SDN)

但任何其他角色和应用都必须运行在 VM 中。But any other roles and apps must run inside of VMs. 请注意,你可以运行用于管理托管 VM 和为了托管 VM 正常运行所需的实用程序、应用和服务。Note that you can run utilities, apps, and services necessary for the management and health of hosted VMs.
