更新和升级Updates and upgrades

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

Azure Stack HCI 解决方案旨在实现可预测的更新和升级体验。Azure Stack HCI solutions are designed to have a predictable update and upgrade experience.

支持期Support period

Microsoft 硬件解决方案合作伙伴预期提供至少五年的硬件服务、支持和安全更新。You can expect hardware service, support, and security updates from Microsoft Hardware Solution Partner for at least five years. Microsoft 为 Azure Stack HCI 操作系统提供两年的支持,并提供年度功能更新,客户最多有一年时间来部署这些更新。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 年度发布路线图

更新 Azure Stack HCIUpdating Azure Stack HCI

与 Windows 10 一样,Azure Stack HCI 将借助 Microsoft 提供的每月质量和安全更新,始终保持最新状态。Like Windows 10, Azure Stack HCI will always be kept up to date with monthly quality and security updates from Microsoft. 使用“群集感知更新”启动更新,与 Windows Server 上一样。You initiate the updates using Cluster-Aware Updating, as on Windows Server.

硬件合作伙伴和解决方案构建者可以插入 Windows Admin Center 并开发扩展,以使服务器的固件、驱动程序和 BIOS 保持最新,并在群集节点之间保持一致。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. 购买预装了 Azure Stack HCI 的集成系统的客户可以通过这些扩展来安装解决方案更新;仅购买经验证的硬件节点的客户可能需要根据硬件供应商的建议单独执行更新。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.

虚拟机也需要定期更新。Virtual machines also need to be updated regularly. 除了 Windows 更新和 Windows Server Update Services 以外,还可以使用 Azure 更新管理来更新 VM。In addition to Windows Update and Windows Server Update Services, you can use Azure Update Management to update VMs.

升级到 Azure Stack HCIUpgrading to Azure Stack HCI

你可以从 Windows Server 2019 升级到 Azure Stack HCI,但不是无缝升级;目前没有就地升级。You can upgrade from Windows Server 2019 to Azure Stack HCI, but not seamlessly; there is no in-place upgrade at this time. 升级需要每个服务器留出一个维护时段和进行清洁安装,并在滚动群集升级过程中分别重新生成每个节点。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

更新群集需要协调业务流程,因为某些更新需要重新启动操作系统,并且必须一次重新启动一个服务器,以确保群集的可用性。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. 群集感知更新 (CAU) 是 Microsoft 的默认群集业务流程协调程序,可实现通过 Windows Admin Center 中的集成更新体验执行更新,或通过 PowerShell 命令手动执行更新。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. 群集感知更新功能可进行扩展,扩展后可支持检索固件和驱动程序更新的合作伙伴插件。Cluster-Aware Updating is extensible to support partner plug-ins that retrieve firmware and driver updates.
