本主题介绍如何使用 Windows 管理中心在 Azure Stack HCI 中的卷上启用 BitLocker 加密。This topic covers how to enable encryption with BitLocker on volumes in Azure Stack HCI using Windows Admin Center. 还介绍了如何在卷上启用重复数据删除和压缩。It also covers how to enable deduplication and compression on volumes. 若要了解如何创建卷,请参阅 创建卷To learn how to create volumes, see Create volumes.

启用 BitLocker 来保护卷Turn on BitLocker to protect volumes

若要在 Windows 管理中心中启用 BitLocker:To turn on BitLocker in Windows Admin Center:

  1. 连接到存储空间直通群集,然后在“工具”窗格上,选择“卷” 。Connect to a Storage Spaces Direct cluster, and then on the Tools pane, select Volumes.

  2. 在 " " 页上,选择 " 清单 " 选项卡,然后在 " 可选功能" 下切换 **加密 (BitLocker) ** 切换。On the Volumes page, select the Inventory tab, and then under Optional features, switch on the Encryption (BitLocker) toggle.

  3. 在“加密 (BitLocker)”弹出项中,选择“开始”,然后在“启用加密”页上,提供凭据以完成工作流 。On the Encryption (BitLocker) pop-up, select Start, and then on the Turn on Encryption page, provide your credentials to complete the workflow.

备注

如果显示“先安装 BitLocker 功能”弹出项,请按照其说明在群集中的每个服务器上安装该功能,然后重新启动服务器。If the Install BitLocker feature first pop-up displays, follow its instructions to install the feature on each server in the cluster, and then restart your servers.

启用重复数据删除和压缩Turn on deduplication and compression

重复数据删除和压缩按卷进行管理。Deduplication and compression are managed per volume. 重复数据删除和压缩使用后处理模型,这意味着在运行之前不会出现节省费用。Deduplication and compression use a post-processing model, which means that you won't see savings until it runs. 在此过程中,它将处理所有文件,甚至是之前的文件。When it does, it will work over all files, even files that were there from before.

若要在 Windows 管理中心的卷上启用重复数据删除和压缩:To turn on deduplication and compression on a volume in Windows Admin Center:

  1. 连接到存储空间直通群集,然后在“工具”窗格上,选择“卷” 。Connect to a Storage Spaces Direct cluster, and then on the Tools pane, select Volumes.

  2. 在“卷”页上选择“库存”选项卡。 On the Volumes page, select the Inventory tab.

  3. 在卷列表中,选择要管理的卷的名称。In the list of volumes, select the name of the volume that you want to manage.

  4. 在 "卷详细信息" 页上,切换到 " 重复数据删除和压缩 " 切换。On the volume details page, switch on the Deduplication and compression toggle.

  5. 在 " 启用重复数据删除 " 窗格上,选择 "重复数据删除" 模式。On the Enable deduplication pane, select the deduplication mode.

    Windows Admin Center 可让你针对不同的工作负荷选择现成的配置文件,而无需进行复杂的设置。Instead of complicated settings, Windows Admin Center lets you choose between ready-made profiles for different workloads. 如果你不确定要如何设置,请使用默认设置。If you're not sure, use the default setting.

  6. 选择 " 启用重复数据删除"。Select Enable deduplication.

启用卷加密对卷性能的影响较小,通常低于10%,但影响取决于硬件和工作负荷。Enabling volume encryption has a small impact on volume performance—typically under 10%, but the impact varies depending on your hardware and workloads. 重复数据删除和压缩还会对性能产生影响-有关详细信息,请参阅 确定哪些工作负荷是重复数据删除的候选项。Data deduplication and compression also has an impact on performance—for details, see Determine which workloads are candidates for Data Deduplication.

大功告成!You're done! 根据需要重复此步骤以保护卷中的数据。Repeat as needed to protect the data in your volumes.
