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

适用于:Azure Stack HCI,版本 20H2Applies to: Azure Stack HCI, version 20H2

Azure Stack HCI 是一种超聚合基础结构, (HCI) 群集解决方案,该解决方案在混合的本地环境中托管虚拟化 Windows 和 Linux 工作负荷及其存储。Azure Stack HCI is a hyperconverged infrastructure (HCI) cluster solution that hosts virtualized Windows and Linux workloads and their storage 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. 可以通过现有工具(包括 Windows 管理中心和 PowerShell)来管理群集。You can manage the cluster with your existing tools including Windows Admin Center and PowerShell.

Azure Stack HCI,版本20H2 现 可供下载Azure Stack HCI, version 20H2 is now 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.

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. 成本不会因物理处理器核心之外的消耗而变化,这意味着更多的 Vm 成本更低,并且能够运行密度越大虚拟环境的客户会获得奖励。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购买验证的服务器,也可以从 OEM 购买验证的裸机服务器,然后订阅 Azure Stack HCI 服务并 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.

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
  • 网络控制器和软件定义的网络所需的其他组件 (SDN) 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.
