Azure Stack HCI 解決方案概觀Azure Stack HCI solution overview

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

Azure Stack HCI 是一種超融合式基礎結構 (HCI) 叢集解決方案,可在混合式內部部署環境中裝載虛擬化的 Windows 和 Linux 工作負載及其儲存體。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 混合式服務利用雲端式監視、Site Recovery 和 VM 備份等功能來增強叢集,以及 Azure 入口網站中所有 Azure Stack HCI 部署的集中式查看。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. 您可以使用現有的工具(包括 Windows Admin Center 和 PowerShell)來管理叢集。You can manage the cluster with your existing tools including Windows Admin Center and PowerShell.

Azure Stack HCI 版本20H2 現在已 可供下載Azure Stack HCI, version 20H2 is now available for download. 它適用于執行虛擬化工作負載的內部部署叢集,並內建混合式雲端連線。It's intended for on-premises clusters running virtualized workloads, with hybrid-cloud connections built-in. 因此,Azure Stack HCI 會以 Azure 服務的形式提供,並以 Azure 訂用帳戶計費。As such, Azure Stack HCI is delivered as an Azure service and billed on an Azure subscription. Azure Stack HCI 現在也包含裝載 Azure Kubernetes Service 的能力;如需詳細資訊,請參閱 Azure Stack HCI 上的 Azure Kubernetes ServiceAzure Stack HCI also now includes the ability to host the Azure Kubernetes Service; for details, see Azure Kubernetes Service on Azure Stack HCI.

請花幾分鐘的時間觀看 Azure Stack HCI 的高階功能影片:Take a few minutes to watch the video on the high-level features of Azure Stack HCI:

Azure Stack HCI 的核心是結合下列各項的解決方案:At its core, Azure Stack HCI is a solution that combines the following:

  • OEM 合作夥伴所驗證的硬體Validated hardware from an OEM partner
  • Azure Stack HCI 作業系統Azure Stack HCI operating system
  • Windows Admin CenterWindows Admin Center
  • Azure 服務Azure services

Azure Stack HCI OS 會在經過驗證的硬體上執行、由 Windows Admin Center 管理,並連接到 Azure

Azure Stack HCI 版本20H2 提供 Windows Server 中沒有的新功能,例如能夠使用 Windows Admin Center 來建立超融合式叢集,以使用儲存空間直接存取以獲得優異的儲存體性價比。Azure Stack HCI, version 20H2 provides new functionality not present in Windows Server, such as the ability to use Windows Admin Center to create a hyperconverged cluster that uses Storage Spaces Direct for superior storage price-performance. 這包括在網站間延展叢集的選項,以在網站間自動容錯移轉。This includes the option to stretch the cluster across sites for automatic failover across sites. 如需詳細資訊,請參閱 Azure Stack HCI 中的新功能See What's new in Azure Stack HCI for details.

Azure Stack HCI 的使用案例Use cases for Azure Stack HCI

Azure Stack HCI 有許多使用案例,但不適合非虛擬化的工作負載。There are many use cases for Azure Stack HCI, although it isn't intended for non-virtualized workloads. 客戶通常會在下列案例中選擇 Azure Stack HCI:Customers often choose Azure Stack HCI in the following scenarios:

資料中心匯總與現代化Data center consolidation and modernization

使用 Azure Stack HCI 重新整理和匯總過時的虛擬化主機可以改善擴充性,並讓您的環境更容易管理和保護。Refreshing and consolidating aging virtualization hosts with Azure Stack HCI can improve scalability and make your environment easier to manage and secure. 也有機會淘汰舊版 SAN 儲存體,以減少使用量和擁有權總成本。It's also an opportunity to retire legacy SAN storage to reduce footprint and total cost of ownership. 使用整合工具和介面,以及單一支援點來簡化作業和系統管理。Operations and systems administration are simplified with unified tools and interfaces and a single point of support.

授權、計費和定價Licensing, billing, and pricing

Azure Stack HCI 計費是以每個實體處理器核心的每月訂閱費用為基礎,而非永久授權。Azure Stack HCI billing is based on a monthly subscription fee per physical processor core, not a perpetual license. 當客戶連接至 Azure 時,所使用的核心數目會自動上傳並評估計費的用途。When customers connect to Azure, the number of cores used is automatically uploaded and assessed for billing purposes. 成本與實體處理器核心以外的耗用量不會有任何差異,這表示更多 Vm 不會有更多成本,而且能夠執行越大虛擬環境的客戶會獲得獎勵。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.

客戶可以從已預先安裝 Azure Stack HCI 作業系統的硬體合作夥伴購買驗證的伺服器,也可以從 OEM 購買驗證的裸機伺服器,然後訂閱 Azure Stack HCI 的服務,並 下載 Azure Stack HCI 的作業系統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.

若要深入瞭解 Azure Stack HCI 20H2 的新功能,請 觀賞 Microsoft 的影片。To learn more about what's new in Azure Stack HCI 20H2, watch this video from Microsoft Inspire.

您可以在不虛擬化的情況下執行的角色Roles you can run without virtualizing

因為 Azure Stack HCI 的目標是在虛擬機器中執行所有工作負載的虛擬化主機,所以 Azure Stack HCI 的條款可讓您只執行裝載虛擬機器所需的功能。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.

這表示您可以執行下列伺服器角色:This means that you can run the following server roles:

  • Hyper-VHyper-V
  • 軟體定義網路 (SDN) 所需的網路控制卡和其他元件Network Controller and other components required for Software Defined Networking (SDN)

但是任何其他角色和應用程式都必須在 Vm 內執行。But any other roles and apps must run inside of VMs. 請注意,您可以執行所需的公用程式、應用程式和服務,以管理託管 Vm 的和健全狀況。Note that you can run utilities, apps, and services necessary for the management and health of hosted VMs.
