準備好部署 DPM 伺服器Get ready to deploy DPM servers

開始部署 System Center Data Protection Manager (DPM) 伺服器之前,需要考慮幾個規劃步驟:There are a few planning steps to consider before you begin to deploy your System Center Data Protection Manager (DPM) servers:

規劃 DPM 伺服器部署Plan for DPM server deployment

首先,決定需要的伺服器數目:First determine how many servers you'll need:

  • DPM 可以保護多達 600 個磁碟區。DPM can protect up to 600 volumes. 若要提供最大容量的保護,DPM 會需要每部 DPM 伺服器 120 TB。To protect this maximum size, DPM needs 120 TB per DPM server.

  • 單一 DPM 伺服器可以保護多達 2000 個資料庫 (建議的磁碟大小 80 TB)。A single DPM server can protect up to 2000 databases (recommended disk size 80 TB).

  • 單一 DPM 伺服器可以保護多達 3000 部用戶端電腦和 100 部伺服器。A single DPM server can protect up to 3000 client computers and 100 servers.

  • 對於使用 DPM 2012 R2 建立的保護群組,DPM 在單一伺服器上有 9000 張磁碟型快照集的限制,包括停止保護資料來源時所保留的那些快照集。For protection groups created using DPM 2012 R2, DPM has a snapshot limit of 9,000 disk-based snapshots on a single server, including those retained when you stop protection of a data source. 快照集限制會套用到快速完整備份和檔案復原點,但不會套用到增量同步處理。The snapshot limit applies to express full backups and file recovery points, but not to incremental synchronizations. 請注意,不論存放集區的大小如何,都會套用此限制。Note that the limit applies regardless of storage pool size. 這些快照集限制並不適用於使用 DPM 2016 建立的保護群組,因為 DPM 2016 不會使用磁碟,但會使用磁碟區。These snapshots limits do not apply to protection groups created using DPM 2016 as DPM 2016 doesn't use disks, but uses volumes.

  • 如需 DPM 伺服器容量規劃,您可以使用 DPM 儲存計算器For DPM server capacity planning you can use the DPM storage calculators. 這些計算器會是 Excel 工作表,且為工作負載專用。These calculators are Excel sheets and are workload specific. 它們提供所需 DPM 伺服器數目、處理器核心、RAM 和虛擬記憶體建議和所需儲存容量的相關指引。They provide guidance about the number of DPM servers required, processor core, RAM, and virtual memory recommendations, and required storage capacity. 因為這些計算機為工作負載專用,所以您必須結合建議的設定,並與系統需求、您的特定商務拓撲和需求 (包括資料來源和儲存位置)、相容性與 SLA 需求,以及災害復原需求一起考量。Because these calculators are workload-specific you'll need to combine the recommended settings and consider them together with the system requirements, and your specific business topology and requirements, including data source and storage locations, compliance and SLA requirements, and disaster recovery needs. 請注意,計算器是針對 DPM 2010 所發行的,但會在更新的 DPM 版本中保留相關項目。Note that the calculators were released for DPM 2010 but remain relevant for later DPM versions.

接著了解如何放置伺服器︰Then figure out how to locate the servers:

  • DPM 必須部署在 Active Directory 網域中 (Windows Server 2008 之後的版本)。DPM must be deployed in an Active Directory domain (Windows Server 2008 onwards).

  • 在決定 DPM 伺服器的置放位置時,請將 DPM 伺服器與受保護電腦之間的網路頻寬納入考量。When deciding where to locate your DPM server, consider the network bandwidth between the DPM server and the protected computers. 如果您要透過廣域網路 (WAN) 來保護資料,最低的網路頻寬需求為每秒 512 KB (Kbps)。If you are protecting data over a wide area network (WAN), there is a minimum network bandwidth requirement of 512 kilobits per second (Kbps).

  • DPM 支援組合網路介面卡 (NIC)。DPM supports teamed network adapters (NICs). 組合 NIC 是多張實體介面卡,設定為要讓作業系統當成單一介面卡來處理。Teamed NICs are multiple physical adapters that are configured to be treated as a single adapter by the operating system. 組合 NIC 可提供增加的頻寬,方法是使用每張介面卡結合可用頻寬,並在介面卡失敗時容錯移轉至其餘的介面卡。Teamed NICs provide increased bandwidth by combining the bandwidth available using each adapter and failover to the remaining adapter when an adapter fails. DPM 可以使用 DPM 伺服器上透過使用組合介面卡實現的增量頻寬。DPM can use the increased bandwidth achieved by using teamed adapter on the DPM server.

  • DPM 伺服器置放位置的另一個考量事項,在於您需要手動管理磁帶和磁帶媒體櫃 (例如,將新磁帶加入媒體櫃或取下磁碟以便異地封存)。Another consideration for the location of your DPM servers is the need to manage tapes and tape libraries manually, such as adding new tapes to the library or removing tapes for offsite archive.

  • DPM 伺服器可以保護網域內的資源,或保護與 DPM 伺服器所在網域具有雙向信任關係的樹系內跨網域的資源。A DPM server can protect resources within a domain, or across domains within a forest that has a two-way trust relationship with the domain that the DPM server is located in. 如果沒有跨網域的雙向信任,則每個網域都必須有個別的 DPM 伺服器。If there isn't a two-way trust across domains, you need a separate DPM server for each domain. 如果樹系之間具有樹系層級的雙向信任,則 DPM 伺服器可以跨樹系保護資料。A DPM server can protect data across forests if there's a forest-level two-way trust between the forests.

  • 請考量 DPM 伺服器和受保護電腦之間的網路頻寬。Consider the network bandwidth between the DPM server and the protected computers. 如果您要透過 WAN 保護資料,最低的網路頻寬需求為 512 Kbps。If you are protecting data over a WAN there's a minimum network bandwidth requirement of 512 Kbps. 請注意,DPM 支援可提供增加的頻寬 (透過結合每張網路介面卡的可用頻寬) 和介面卡失敗時容錯移轉的組合 NIC。Note that DPM supports teamed NICs that provide increased bandwidth by combining bandwidth available for each network adapter, and failover if an adapter fails.

規劃防火牆設定和使用者權限Plan firewall settings and user permissions

防火牆設定Firewall settings

在 DPM 伺服器上、您想要保護的電腦上,以及用於 DPM 資料庫的 SQL Server 上 (如果在遠端執行),需要部署 DPM 的防火牆設定。Firewall settings for DPM deployment are required on the DPM server, on machines you want to protect, and on the SQL Server used for the DPM database if you're running it remotely. 如果在您安裝 DPM 時已啟用 Windows 防火牆,則 DPM 安裝程式會自動在 DPM 伺服器上進行防火牆設定。If Windows Firewall is enabled when you install DPM then DPM setup automatically configures the firewall settings on the DPM server. 下表摘要說明這些防火牆設定。The firewall settings are summarized in the following table.
