更新和升級Updates and upgrades

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

Azure Stack HCI 的解決方案是設計來提供可預測的更新和升級體驗。Azure Stack HCI solutions are designed to have a predictable update and upgrade experience.

支援期間Support period

您可以預期 Microsoft 硬體解決方案合作夥伴至少有五年的硬體服務、支援和安全性更新。You can expect hardware service, support, and security updates from Microsoft Hardware Solution Partner for at least five years. Microsoft 支援 Azure Stack HCI 的作業系統有兩年,而每年的功能更新則是客戶最多一年進行部署。The Azure Stack HCI operating system is supported by Microsoft for two years, with annual feature updates that the customer has up to one year to deploy.

Azure Stack HCI 年度發行藍圖

更新 Azure Stack HCIUpdating Azure Stack HCI

就像 Windows 10 一樣,Azure Stack HCI 一律會保持最新狀態,並提供 Microsoft 的每月品質和安全性更新。Like Windows 10, Azure Stack HCI will always be kept up to date with monthly quality and security updates from Microsoft. 您可以使用 Windows Server 上的叢集感知更新來起始更新。You initiate the updates using Cluster-Aware Updating, as on Windows Server.

硬體夥伴和解決方案產生器可以插入 Windows Admin Center 並開發延伸模組,以將伺服器的固件、驅動程式和 BIOS 維持在最新狀態,並在叢集節點之間保持一致。Hardware partners and solution builders can plug into Windows Admin Center and develop extensions to keep the firmware, drivers, and BIOS of servers up-to-date and consistent across cluster nodes. 購買已預先安裝 Azure Stack HCI 的整合系統的客戶可以透過這些擴充功能安裝解決方案更新;只要購買經過驗證的硬體節點,客戶可能必須根據硬體廠商的建議個別執行更新。Customers who purchase an integrated system with Azure Stack HCI pre-installed can install solution updates via these extensions; customers who simply purchase validated hardware nodes may need to perform the updates separately, according to the hardware vendor's recommendations.

虛擬機器也需要定期更新。Virtual machines also need to be updated regularly. 除了 Windows Update 和 Windows Server Update Services 之外,您還可以使用 Azure 更新管理來更新 Vm。In addition to Windows Update and Windows Server Update Services, you can use Azure Update Management to update VMs.

升級至 Azure Stack HCIUpgrading to Azure Stack HCI

您可以從 Windows Server 2019 升級到 Azure Stack HCI,但無法順暢地升級;目前沒有就地升級。You can upgrade from Windows Server 2019 to Azure Stack HCI, but not seamlessly; there is no in-place upgrade at this time. 升級需要在每部伺服器上維護時段和全新安裝,在輪流叢集升級過程中個別重建每個節點。Upgrading requires a maintenance window and a clean install on each server, rebuilding each node individually as part of a rolling cluster upgrade.

Cluster-Aware UpdatingCluster-Aware Updating

更新叢集需要協調流程,因為某些更新需要作業系統重新開機,且伺服器必須一次重新開機,以確保叢集的可用性。Updating a cluster requires orchestration because some updates require an operating system restart and servers must be restarted one at a time to ensure availability of the cluster. 叢集感知更新 (CAU) 是 Microsoft 的預設叢集協調器,可讓您透過 Windows Admin Center 中的整合式更新體驗或透過 PowerShell 命令手動執行更新。Cluster-Aware Updating (CAU) is Microsoft's default cluster orchestrator, allowing updates to be performed either through an integrated update experience in Windows Admin Center or manually via PowerShell commands. 叢集感知更新是可擴充的,可支援可捕獲固件和驅動程式更新的合作夥伴外掛程式。Cluster-Aware Updating is extensible to support partner plug-ins that retrieve firmware and driver updates.
