本主題說明如何使用 Windows Admin Center 在 Azure Stack HCI 的磁片區上啟用 BitLocker 加密。This topic covers how to enable encryption with BitLocker on volumes in Azure Stack HCI using Windows Admin Center. 它也涵蓋如何在磁片區上啟用重復資料刪除和壓縮。It also covers how to enable deduplication and compression on volumes. 若要瞭解如何建立磁片區,請參閱 建立磁片區。To learn how to create volumes, see Create volumes.

開啟 BitLocker 來保護磁片區Turn on BitLocker to protect volumes

若要在 Windows Admin Center 中開啟 BitLocker:To turn on BitLocker in Windows Admin Center:

  1. 連線到儲存空間直接存取叢集,然後在 [ 工具 ] 窗格中選取 [ 磁片區]。Connect to a Storage Spaces Direct cluster, and then on the Tools pane, select Volumes.

  2. 在 [ 磁片 區] 頁面上,選取 [ 清查 ] 索引標籤,然後在 [ 選用功能] 下,切換 **加密 (BitLocker) ** 切換。On the Volumes page, select the Inventory tab, and then under Optional features, switch on the Encryption (BitLocker) toggle.

    切換開關以啟用 BitLocker

  3. 在 [ **加密 (BitLocker]) ** 快顯視窗上,選取 [ 開始],然後在 [ 開啟加密 ] 頁面上,提供您的認證以完成工作流程。On the Encryption (BitLocker) pop-up, select Start, and then on the Turn on Encryption page, provide your credentials to complete the workflow.

注意

如果出現 [ 安裝 BitLocker 功能] 第一個 快顯視窗,請依照其指示,在叢集中的每部伺服器上安裝此功能,然後重新開機伺服器。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.

開啟重復資料刪除和壓縮Turn on deduplication and compression

每個磁片區會管理重復資料刪除和壓縮。Deduplication and compression are managed per volume. 重復資料刪除和壓縮會使用後置處理模型,這表示在執行之前,您不會看到節省成本。Deduplication and compression use a post-processing model, which means that you won't see savings until it runs. 當它執行時,它會處理所有檔案,甚至是之前的檔案。When it does, it will work over all files, even files that were there from before.

若要在 Windows Admin Center 中開啟磁片區上的重復資料刪除和壓縮:To turn on deduplication and compression on a volume in Windows Admin Center:

  1. 連線到儲存空間直接存取叢集,然後在 [ 工具 ] 窗格中選取 [ 磁片區]。Connect to a Storage Spaces Direct cluster, and then on the Tools pane, select Volumes.

  2. 在 [ 磁片 區] 頁面上,選取 [ 清查 ] 索引標籤。On the Volumes page, select the Inventory tab.

  3. 在磁片區清單中,選取您要管理之磁片區的名稱。In the list of volumes, select the name of the volume that you want to manage.

  4. 在 [磁片區詳細資料] 頁面上,切換 重復資料刪除和壓縮 切換。On the volume details page, switch on the Deduplication and compression toggle.

  5. 在 [ 啟用重復資料刪除 ] 窗格中,選取重復資料刪除模式。On the Enable deduplication pane, select the deduplication mode.

    Windows Admin Center 可讓您在適用于不同工作負載的現成設定檔之間做選擇,而不是複雜的設定。Instead of complicated settings, Windows Admin Center lets you choose between ready-made profiles for different workloads. 如果您不確定,請使用預設設定。If you're not sure, use the default setting.

  6. 選取 [ 啟用重復資料刪除]。Select Enable deduplication.

啟用磁片區加密對磁片區效能的影響很小(通常低於10%),但影響會依您的硬體和工作負載而有所不同。Enabling volume encryption has a small impact on volume performance—typically under 10%, but the impact varies depending on your hardware and workloads. 重復資料刪除和壓縮也會對效能產生影響。如需詳細資料,請參閱 判斷哪些工作負載是重復資料刪除的候選專案。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! 視需要重複,以保護您的磁片區中的資料。Repeat as needed to protect the data in your volumes.
