SharePoint Server 的全域架構Global architectures for SharePoint Server

摘要: 了解 WAN 環境中支援的SharePoint Server 2013和SharePoint Server 2016的架構、透過 WAN 連線以最佳化效能的策略,以及服務應用程式的建議措施。Summary: Learn about supported architectures for SharePoint Server 2013 and SharePoint Server 2016 in WAN environments, strategies for optimizing performance over WAN connections, and recommendations for service applications.

SharePoint Server 已經過最佳化,能夠透過廣域網路 (WAN) 連線正常運作。對於大多數的客戶來說,集中式環境是為廣域使用者提供服務建議使用的架構。擁有非良好連線網站的客戶可以受益於部署一或多個區域伺服器陣列。本文說明支援的架構、為 WAN 連線最佳化 SharePoint Server 的策略,以及服務應用程式的建議措施。SharePoint Server is optimized to perform well over wide-area network (WAN) connections. For most customers, a centralized environment is the recommended architecture for serving a world-wide user base. Customers who have sites that are not well connected might benefit from deploying one or more regional farms. This article describes supported architectures, strategies to optimize SharePoint Server for WAN connections, and recommendations for service applications.

重要概念Key concepts

本文使用下列術語:This article uses the following terms:

  • 中央網站 主控大多數的公司資料與員工電腦的位置。集中式 SharePoint Server 環境可以包含一個單一伺服器陣列或位於同一資料中心的多個伺服器陣列。Central site—The location that hosts most of the company data and employee computers. A centralized SharePoint Server environment can consist of a single farm or multiple farms located in the same datacenter.

  • 地區網站 — 主控組合使用區域網路 (LAN) 及 WAN 連結來連線之公司資料與員工電腦的子集合的位置。Regional site—A location that hosts a subset of corporate data and employee computers that are connected by using a combination of local-area network (LAN) and WAN links.

  • 分散式環境 — 員工與公司資料分佈在全球的環境。Distributed environment—An environment in which employees and company data are dispersed across the globe.

  • 國內伺服器陣列 — 部署於政治邊界內以符合政府法規的伺服器陣列。In-country farm — A farm that is deployed inside a political boundary to satisfy government regulations.

評估您的 WAN 連線Evaluate your WAN connections

驅動 WAN 環境最重要的因素是整個 WAN 連線內的 SharePoint Server 效能。在考量 WAN 環境的架構選項之前,您首先要評估使用者最常執行之動作的效能體驗。這可以透過對多個 WAN 連線使用系統化基準測試,或者對測試環境進行簡單的使用者測試來達成。您也可以在主要公司位置的相同區域內的 Office 365 建立評估網站,然後從多個地理位置測試使用者經驗。The most important factor that drives architectures for WAN environments is the performance of SharePoint Server across the WAN connections. Before you consider architecture options for your WAN environment, first evaluate the performance that users will experience for the most common actions they will perform. This can be done by using systematic benchmark testing across multiple WAN connections, or with simple user testing against a test environment. You can also create an evaluation site in Office 365 within the same region as the main company location, and test the user experience from multiple geographic locations.

如果貴組織目前使用早期版本的產品在多個地區部署伺服器陣列,則只要使用單一中央伺服器陣列環境或者較少的伺服器陣列便能成功。請不要假設貴組織需要的伺服器陣列數目與您以早期版本部署的伺服器陣列數目相同。If your organization currently deploys more than one farm geographically by using an earlier version of the product, you might be able to succeed with either a single, central-farm environment or with fewer farms. Do not assume that your organization will require the same number of farms as you deployed with an earlier version.

最佳化中央伺服器陣列或中央資料中心部署Optimize a central farm or central datacenter deployment

為廣域使用者提供服務的第一個且最佳的選項是在中央環境部署 SharePoint Server。The first and best option to serve a world-wide user base is to deploy SharePoint Server to a central environment.

中央環境模型

由於 SharePoint Server 的效能大幅提升,同時使用 WAN 連線的全球客戶預期能夠透過集中式部署 SharePoint Server 而獲得成功。對於企業級的客戶而言,這可能包括在單一資料中心部署的多個伺服器陣列。大多數客戶只要部署單一伺服器陣列便能夠滿足組織需求 (例如,United Airlines)。組織也可以使用 Office 365 作為中央環境來為廣域使用者提供服務。Due to the performance improvements in SharePoint Server global customers who are well connected with WAN connections can expect to succeed with a centralized deployment of SharePoint Server. For enterprise-scale customers, this might include more than one farm that is deployed to a single datacenter. Most customers can deploy a single farm to meet the needs of an organization (for example, United Airlines). Organizations can also use Office 365 as a central environment to serve a world-wide user base.

如果您在內部部署 SharePoint Server,有多種策略可以協助最佳化 WAN 連線的集中式環境。If you deploy SharePoint Server on premises, several strategies can help optimize a centralized environment across WAN connections.

最佳化網頁以加速下載Optimize web pages for faster downloads

SharePoint Server 的預設頁面已針對效能進行最佳化。如果您自訂頁面、或新增許多影像、或其他類型的內容,請確定對這些頁面進行最佳化以便能夠透過 WAN 連線正常運行。The default pages in SharePoint Server are optimized for performance. If you customize pages or add many images or other types of content, make sure that you optimize these pages so they perform well over WAN connections.

Windows Server 功能Windows Server features

Windows Server 有多種功能可以為透過地區網站或分公司連線到中央環境的使用者提升效能。Several features in Windows Server can improve performance for users who connect to a central environment through a regional site or branch office.

  • BranchCache-- BranchCache 是 Windows 7、Windows Server 2008 R2 及 Windows Server 2012 作業系統的一項功能,可快取檔案以及 WAN 上的網頁伺服器和地區分公司電腦上的內容。在地理分散式 SharePoint Server 環境中,BranchCache 可以藉由快取使用者從 SharePoint Server 下載的大型檔案來最佳化 WAN 效能。BranchCache-- BranchCache, a feature of the Windows 7, Windows Server 2008 R2, and Windows Server 2012 operating systems, caches content from file and web servers on a WAN on computers at a local branch office. In a geographically distributed SharePoint Server environment, BranchCache can optimize WAN performance by caching large files that users download from SharePoint Server.

  • 服務品質 (QoS) Windows 2000 引進的 QoS 功能已在 Windows Server 2012 大幅增強。QoS 能夠評量網路頻寬、偵測網路條件變化 (例如,壅塞或頻寬可用性) 以及安排網路流量優先順序或網路流量節流,讓您滿足工作量或應用程式的服務需求。例如,您可以使用 QoS 來安排不允許延遲的應用程式流量,並控制允許延遲流量的影響 (例如,大量資料傳輸)。您可以使用 QoS 來設定對使用者非常重要之應用程式的要求優先順序。此外,您也可以將對效能有不利影響的應用程式或程序設定為較低優先順序,例如備份程序或大型下載。如需 Windows Server 2012 的 QoS 功能詳細資訊,請參閱<服務品質 (QoS) 概觀>。Quality of Service (QoS)— Windows 2000 introduced QoS features that Windows Server 2012 has enhanced. QoS enables you to meet the service requirements of a workload or an application by measuring network bandwidth, detecting changing network conditions (such as congestion or availability of bandwidth), and prioritizing - or throttling - network traffic. For example, you can use QoS to prioritize traffic for latency-sensitive applications and to control the effect of latency-insensitive traffic (such as bulk data transfers). You can use QoS to prioritize requests for applications that are critical for users. In addition, you can deprioritize applications or processes that adversely affect performance, such as backup processes or large downloads. For more information about QoS features in Windows Server 2012, see Quality of Service (QoS) Overview.

WAN 加速器WAN accelerators

WAN 加速器有利於內部網路部署。有些全球性公司跨最高延遲連線設置 WAN 加速器,將這些網站的效能提升至可接受的範圍內。這些解決方案通常是在多個層次最佳化流量。WAN accelerators benefit intranet deployments. Some global companies position WAN accelerators across the highest latency connections to improve performance at these sites to an acceptable range. These solutions typically optimize traffic at several levels.

  • WAN 加速解決方案可以壓縮網路層級封包及最佳化基礎通訊協定,以減少原始流量。WAN acceleration solutions compress network-level packets and optimize the underlying protocol to reduce the raw traffic.

  • WAN 加速器以比較內容區塊與最近傳送之區塊歷史記錄的方式最佳化內容,並藉此僅傳送差異部分而不是所有內容。WAN accelerators optimize content by comparing content blocks against a history of recently sent blocks, which enables only differences to be sent instead of all the content.

  • 應用程式感知的裝置可最佳化應用程式層級通訊協定以減少應用程式交談。Application-aware devices optimize the application-level protocol which reduces the application chatter.

不同的解決方案使用不同的最佳化技術與演算法組合。不同的解決方案使用不同的最佳化技術與演算法組合。Different solutions use different combinations of optimization techniques and algorithms.

WAN 加速器為成對運作。其中一個裝置位於執行 SharePoint Server 之伺服器旁的資料中心內,另一個裝置則是位於分公司內或分公司外部的用戶端裝置上。高延遲網路廠商的回應時間 (秒) 或後續要求因此能夠減少90% 或更多。WAN accelerators work in pairs. One device is in the data center next to the servers that are running SharePoint Server, and another device is in the branch office or on a client device outside an office. Vendors claim 90% or more reduction in response time for second and successive requests over high-latency networks.

有多種 WAN 加速器裝置可用。每個裝置以各種不同的方式最佳化 WAN 流量。由於 SharePoint Server 可同時最佳化及壓縮資料,因此測試採用與不採用 SharePoint Server 的效能非常重要。在某些情況下,相較於所達成的效益,多重技術 (SharePoint Server、IIS 及 WAN 加速器) 的壓縮對效能可能有不利影響。Many WAN accelerator devices are available. Each device optimizes WAN traffic in different ways. Because SharePoint Server also optimizes and compresses data, it is important to test the performance of SharePoint Server both with and without WAN acceleration devices. In some cases, the compression of multiple technologies (SharePoint Server, IIS, and a WAN accelerator) might adversely affect performance compared to the benefit achieved.

最佳化網路Optimize the network

許多客戶可以和頻寬提供者一起建立可運作的集中式環境,來最佳化使用者與中央網站之間的網路連線。此外,特別是在新興市場,有些電信公司則是提供更有效率的路由模式。和在多個位置管理 SharePoint 伺服器陣列與內容的複雜性相較,最佳化 WAN 連線可能是更實際的作法。Many customers can make a centralized environment work by working with bandwidth providers to optimize the network connections between users and a central site. Also, some telecommunications companies provide more efficient routing patterns, especially in emerging markets. Compared to the complexity of managing SharePoint farms and content at multiple locations, it might be more practical to optimize the WAN connections instead.

WAN 環境的用戶端工具Client tools for WAN environments

許多用戶端工具不需要在全球部署多個伺服器陣列便能夠大幅提升使用者的 WAN 連線經驗。您也可以在部署多個伺服器陣列的不同地區環境中運用這些工具。Several client tools can greatly improve the user experience over WAN connections without deploying multiple farms across the globe. You can also use these tools in environments that have multiple farms that are deployed geographically.

Office Online ServerOffice Online Server

Office Online 伺服器 是一款 Office 伺服器產品,可提供瀏覽器版本的 Word、PowerPoint、Excel 及 OneNote。由於使用者不需要上傳或下載檔案,Office Online 伺服器 因此能夠大幅提升 WAN 環境的效能。單一 Office Online 伺服器 伺服器陣列可以支援透過 SharePoint Server 2016、商務用 Skype Server 2015 及 Exchange Server 2013 來存取 Office 檔案的使用者。Office Online 伺服器 能夠在高延遲連線或低頻寬連線或此兩者的環境下正常運作。在間歇性連線的環境則無法發揮效能。Office Online Server is an Office server product that delivers browser-based versions of Word, PowerPoint, Excel, and OneNote. Office Online Server greatly improves performance in WAN environments because users don't upload or download files. A single Office Online Server farm can support users who access Office files through SharePoint Server 2016, Skype for Business Server 2015, and Exchange Server 2013. Office Online Server works well in environments that have high-latency connections, or low bandwidth connections, or both. It might not work well in environments that have intermittent connections.

Office Online 伺服器 伺服器陣列通常位於和 SharePoint Server 2016 伺服器陣列相同的資料中心內,但這不是必要條件。將 Office Online 伺服器 伺服器陣列放置在不是 SharePoint 網站所在的遠端資料中心內並不會提升效能。如需詳細資訊,請參閱<Office Web Apps Server overview>。A Office Online Server farm is typically located in the same datacenter as the SharePoint Server 2016 farm, although this is not a requirement. Locating a Office Online Server farm in a remote datacenter where SharePoint sites are not located will not improve performance. For more information, see Office Web Apps Server overview.

商務用 OneDriveOneDrive for Business

商務用 OneDrive 可讓使用者將「我的網站」文件庫或小組網站上的其他 SharePoint 文件庫同步至自己的電腦。使用者能夠在自已的 [檔案總管] 中直接使用這些檔案。甚至在離線時使用者也能夠存取這些檔案。當使用者上線時,檔案更新便會和 SharePoint 同步。OneDrive for Business lets users sync their My Site library or other SharePoint libraries on team sites to their computers. They can then work with files in these libraries directly in Windows Explorer. Users can access these files even when they are offline. Updates to files sync with SharePoint when a user is online.

商務用 OneDrive 能夠在具有間歇性連線的環境或具有高延遲或低頻寬連線的環境中正常運作。它的設計目的不是讓多位使用者能夠同時離線編輯同一個檔案。如需詳細資訊,請參閱<將 OneDrive 或其他 SharePoint 文件庫同步至使用商務用 OneDrive 的電腦>。OneDrive for Business works well in environments that have intermittent connections or in environments that have high latency or low bandwidth connections. It is not intended to be used by many users who are editing the same file offline at the same time. For more information see Sync your OneDrive or other SharePoint libraries to your computer with OneDrive for Business.

注意

此時,SharePoint Server 中無法使用商務用 OneDrive 新一代的同步處理用戶端。At this time, the OneDrive for Business next generation sync client is not available in SharePoint Server.

設計具有多個伺服器陣列的中央網站Design a central site with multiple farms

部分企業可能會選擇在中央網站部署多個伺服器陣列以滿足擴充與容量需求。不過,如果架構包含多個內容伺服器陣列,社交功能可能會受到限制。若要最佳化多伺服器陣列環境,請遵循下列設計原則:Some enterprises might choose to deploy more than one farm at a central site to meet scale and capacity requirements. However, if the architecture includes more than one content farm, social features may be limited. To optimize a multi-farm environment the following design principles apply:

  • User Profile Service 應用程式必須位於與所支援之內容相同的資料中心。The User Profile Service application must reside in the same datacenter as the content that it supports.

  • 建議使用一個「我的網站」伺服器陣列。跨多個「我的網站」伺服器陣列的社交功能會受到限制。例如,使用者將只從該伺服器陣列看到自己的「我的網站」新聞摘要。多個「我的網站」伺服器陣列還需要多個 User Profile Service 應用程式,這會增加複雜性。One My Site farm is recommended. Social features are limited across multiple My Site farms. For example, users will see social activities in their My Site newsfeed from that farm alone. Multiple My Site farms also require multiple User Profile service applications which increase complexity.

  • 對於跨內容伺服器陣列作業的社交功能,您必須在資料中心的每個內容伺服器陣列上建立「我的網站主機」。在此設計中,位於指定「我的網站」伺服器陣列 (User Profile Service 應用程式所在) 上的「我的網站主機」是主要的「我的網站主機」。其他的「我的網站主機」可支援位於內容伺服器陣列之小組網站的網站摘要。For social features to work across content farms, you must create a My Site Host on each content farm in the datacenter. In this design, the My Site Host on the designated My Site farm, where the User Profile Service application exists, is the primary My Site Host. The other My Site Hosts support site feeds on team sites that are located in the content farms.

  • SharePoint Server 支援延伸的伺服器陣列架構,其伺服器位於不同的資料中心內。延伸的伺服器陣列如要運作,執行 SQL Server 的電腦與前端網頁伺服器之間一個方向的延遲必須小於 1 毫秒,而且頻寬至少每秒 1 Gigabit。SharePoint Server supports stretched farm architectures in which servers are located in different datacenters. For a stretched farm to work, there must be less than 1 millisecond latency between the computer that is running SQL Server and the front-end web servers in one direction, and at least 1 gigabit per second bandwidth.

  • 搜尋伺服器陣列可以位於不同的資料中心。Search Service 應用程式可在 WAN 連線正常運作。如果您要跨資料中心擴展伺服器陣列,您不需要在與其他類型 SharePoint 伺服器陣列相同的資料中心內放置專用搜尋伺服器陣列。Search farms can reside in a different datacenter. The Search service application works well over WAN connections. If you have to spread farms across datacenters, a dedicated search farm does not have to be located in the same datacenter as other types of SharePoint farms.

下圖呈現專為虛構名稱為 Fabrikam 的全球性製造公司設計,並擁有超過 300,000 位使用者的多伺服器陣列架構。The following illustration represents a multi-farm architecture designed for a global manufacturing company that is fictionally named Fabrikam and has more than 300,000 users.

全球製造公司的多伺服器陣列架構

您可以跨伺服器陣列共用部分服務應用程式。它們大多數都能夠在 WAN 連結所分隔的伺服器陣列共用。下表是跨 WAN 連結共用服務應用程式的支援摘要。表格之後提供 Search Service 應用程式要求此服務更詳盡的考量與建議。You can share some service applications across farms. Most of these can be shared across farms separated by WAN links. The following table summarizes the support for sharing service applications across WAN links. The Search service application requires greater consideration and recommendation for this service are provided after the table.

支援 WAN 環境的跨伺服器陣列服務Cross-farm services support for WAN environments

服務應用程式Service application 是否跨 WAN 連線支援?Supported over WAN connections? 附註Notes
搜尋Search
Yes
內容可以透過 WAN 連線編目。或者,您可以設定搜尋,從遠端結果來源擷取結果 (遠端伺服器陣列上的索引)。Content can be crawled over WAN connections. Or, you can configure search to retrieve results from remote result sources (indexes at remote farms).
受管理的中繼資料Managed Metadata
Yes
如果連線不在線上 (例如,間歇性衛星連結),Managed Metadata Service 應用程式提供的使用者項目欄位可能無法使用。User entry fields that the Managed Metadata service application provides might not be available if a WAN connection is not online (such as an intermittent satellite link).
Business Data ConnectivityBusiness Data Connectivity
Yes
在資料模型快取到遠端伺服器陣列 (使用中央伺服器陣列之 Business Data Connectivity Service 的伺服器陣列) 的網頁伺服器之後,遠端伺服器陣列會透過 WAN 直接連線到資料來源查詢資料 (而不是重新連線到主控 Business Data Connectivity Service 的伺服器陣列)。因此,遠端伺服器陣列需要存取資料來源的權限。此外,遠端伺服器陣列與資料來源之間的效能取決於 WAN 連線的效能。After the data model is cached on the web server of the remote farm (the farm that consumes the Business Data Connectivity service from a central farm), the remote farm connects directly to the data source over the WAN to query the data (instead of reconnecting to the farm that is hosting the Business Data Connectivity service). Therefore, the remote farm requires permission to access the data source. Also, performance between the remote farm and the data source depends on the performance of the WAN connection.
使用者設定檔User Profile
不支援Not supported
不支援跨 WAN 連結使用 User Profile Service 應用程式。此服務需要直接存取資料庫。Using the User Profile service application across WAN links is not supported. This service requires direct database access.
Secure Store ServiceSecure Store Service
Yes
儘管 Secure Store Service 可以透過 WAN 連結作業,我們不建議這種用法,因為它可能對其他透過 WAN 連結提供之服務的效能有不利的影響。Although the Secure Store Service works across WAN links, we do not recommend this use because it might adversely affect the performance of other services over a WAN link.
Machine Translation ServiceMachine Translation Service
Yes

您可以透過 WAN 連線共用 Search Service 應用程式。不過,如果 WAN 連線非常穩定並足夠支援透過 WAN 執行編目內容,則連線似乎夠穩定而可支援使用者動作透過 WAN 傳送至中央伺服器陣列。除了透過 WAN 連線共用 Search Service 應用程式外,建議您排除區域伺服器陣列並改成讓使用者使用中央伺服器陣列環境來取得 WAN 效能提升的優勢。You can share the Search service application across WAN connections. However, if a WAN connection is robust enough to support crawling content over the WAN, the connection is likely robust enough to support user actions over the WAN to a central farm. Instead of sharing the Search service application over WAN connections, we recommend that you take advantage of WAN performance improvements by eliminating the regional farm and having users use a central farm environment instead.

下列 WAN 條件可能是建立區域伺服器陣列的理由:The following WAN conditions may be reasons for creating regional farms:

  • 最高延遲連線Highest latency connections

  • 間歇性連線Intermittent connections

  • 網路壅塞造成的不可靠連線Unreliable connections caused by network congestion

  • 無效率的路由模式Inefficient routing patterns

  • 封包遺失Packet loss

我們不建議透過這些類型的 WAN 連線共用 Search Service 應用程式。相反地,我們建議您在區域伺服器陣列上設定搜尋,並使用遠端 SharePoint 結果來源將區域伺服器陣列和中央伺服器陣列的搜尋結果組合在一起。We do not recommend sharing the Search service application across these types of WAN connections. Instead, we recommend that you configure Search on the regional farm and use Remote SharePoint result sources to bring together search results from the regional farm(s) and the central farm.

國內伺服器陣列代表的是不同挑戰。如果國內伺服器陣列的用途是在於預防文件與檔案存放在政治邊界之位的位置,我們則不建議透過 WAN 進行編目內容。搜尋索引至少會包含分散的編目內容。而且,每個文件的暫存複本都要下載至搜尋伺服器陣列進行處理。因此,進行國內伺服器陣列編目的中央伺服器陣列會在該國內伺服器陣列中包含資料的複本。如果這違反公司原則,建議您改成使用遠端 SharePoint 結果來源。藉由這種組態,除非使用者將複本下載至自己的電腦,否則搜尋結果可以包括國內伺服器陣列的內容,內容也可以繼續放置在本機伺服器陣列上。In-country farms represent a different challenge. If the purpose of an in-country farm is to prevent documents and files from residing in locations outside a political boundary, we do not recommend crawling content over the WAN. A search index contains at least fragments of the crawled content. Furthermore, a temporary copy of each document is downloaded to the search farm for processing. Therefore, a central farm that crawls an in-country farm includes a copy of the data in that in-country farm. If this is against company policy, we recommend that you use Remote SharePoint result sources instead. With this configuration, search results can include content from an in-country farm and content continues to reside only on the local farm, unless a user downloads a copy to their local computer.

有一種案例允許透過 WAN 連線進行編目內容,即運用內含使用內部部署的 SharePoint Server 伺服器陣列來編目 Office 365 專用伺服器陣列 (O365-D) 的內容並將搜尋服務提供給該伺服器陣列的混合部署。藉由 Office 365 專用訂閱計畫,每個客戶環境都會被放置在專用伺服器陣列中。編目 Office 365 專用伺服器陣列能夠為兩個環境提供單一的關聯性排序的結果集合。專用 Office 365 環境不同於多承租人 Office 365 環境。對於包含 Office 365 多承租人環境的混合式環境,編目多承租人環境並不可行,建議作法是使用遠端結果來源來提供集中式搜尋。The one scenario in which crawling content over WAN connections is allowed is with a hybrid deployment in which an on-premises SharePoint Server farm is used to crawl content in an Office 365 Dedicated farm (O365-D) and provide search services to that farm. With the Office 365 Dedicated subscription plan each customer environment is placed on a dedicated server farm. Crawling the Office 365 dedicated farm provides a single relevancy-ranked set of results for the two environments. The dedicated Office 365 environment differs from the multi-tenant Office 365 environment. For hybrid environments that include the Office 365 multi-tenant environment, crawling the multi-tenant environment is not possible and the recommendation is to provide centralized search by using remote result sources.

儘管有這些建議,您仍可以利用下列方法來支援與實作透過 WAN 連線共用 Search Service 應用程式:Despite the recommendations, sharing the Search service application over WAN connections is supported and can be implemented in the following ways:

  • 區域伺服器陣列可以使用中央伺服器陣列的 Search Service 應用程式並使用該程式以本機方式進行內容編目。您需要設定跨伺服器陣列服務共用關係並完成額外的設定。在這種情況下,中央伺服器陣列上的搜尋元件可以對區域伺服器陣列的內容進行編目。內容編目所需的通訊則是透過 WAN 連線。不建議使用這種組態。相反地,您可以在區域伺服器陣列上直接部署和設定 Search Service 應用程式。A regional farm can consume the Search service application from a central farm and use it to crawl content locally. You have to set up a cross-farm service sharing relationship and complete additional configuration. In this case, the search components on the central farm crawl content on the regional farm. Communication that is necessary to crawl content occurs over the WAN connection. This configuration is not recommended. Instead, deploy and configure the Search service application directly on the regional farm.

  • 中央伺服器陣列的 Search Service 應用程式可以編目區域伺服器陣列的內容。這種組態不需要設定跨伺服器陣列服務共用。相反地,必須在中央伺服器陣列新增編目規則才能夠編目遠端伺服器陣列的內容。不過,這種組態可以透過 WAN 連線編目內容,但不是理想的作法。A Search service application at a central farm can crawl content at a regional farm. This configuration does not require you to set up cross-farm service sharing. Instead, crawl rules are added at the central farm to crawl content at a remote farm. However, this configuration crawls content over the WAN connection, which is not ideal.

下表列出透過 WAN 進行編目與使用遠端結果來源將內容包括在搜尋結果兩者之間差異的摘要。The following table summarizes the differences between crawling over the WAN and using remote result sources to include content in search results.

將全域內容包括在搜尋結果中的選項Options for including global content in search results

透過 WAN 進行編目Crawl over the WAN 設定遠端伺服器陣列的結果來源Configure a result source for remote farms
說明Description
中央網站透過 WAN 編目區域網站的內容。Content at regional sites is crawled from the central site over the WAN.
搜尋設定成從一或多個遠端伺服器陣列 (結果來源) 以及本機伺服器陣列傳回結果。Search is configured to return results from one or more remote farms (result source), in addition to the local farm.
在此案例中,遠端伺服器陣列以本機方式進行編目。您可以將中央伺服器陣列的搜尋設定成包括遠端索引的結果。In this scenario, remote farms are crawled locally. You configure search at the central farm to include results from the remote indexes.
您也可以將遠端伺服器陣列設定成包括中央伺服器陣列以及其他區域伺服器陣列的結果。藉此使用者便能夠從本機伺服器陣列進行搜尋。You can also configure the remote farms to include results from the central farm and other regional farms. This allows users to search from the local farm.
使用者經驗User experience
使用者面對的是單一的結果清單。Users are presented with a single list of results.
結果是以單一清單呈現。不過,結果會依結果來源分組成不同區塊。您可以設定每個群組內的結果數目。Results are presented in in a single list. However, the results are grouped in blocks by result source. You can configure the number of results within each group.
優點Advantages
搜尋結果包含在按搜尋排序的單一清單中。Search results are contained in a single search-ranked list.
集中管理搜尋。Search is managed centrally.
不使用 WAN 編目。WAN crawling is not used.
視編目排程而定,可能會有更新的搜尋結果。Search results are potentially fresher, based on the crawl schedule.
如果您還將遠端伺服器陣列設定成包括其他伺服器陣列的結果來源,則除了中央伺服器陣列外,遠端伺服器陣列也能夠進行整體企業搜尋。If you also configure remote farms to include result sources for other farms, enterprise-wide search is available from remote farms in addition to the central farm.
缺點Disadvantages
透過 WAN 進行編目會佔用時間與頻寬。Crawling over the WAN takes time and uses bandwidth.
如果內容是以本機方式編目,搜尋結果可能不是最新。Search results might not be as fresh as if the content were crawled locally.
只能從中央伺服器陣列進行整體企業搜尋。Enterprise-wide search is available only from the central farm.
使用者看到多種分組的結果。Users see multiple groupings of results.
搜尋結果未依整個組織排名。Search results are not ranked across the organization.
必須由多個位置管理搜尋。Search must be managed at multiple locations.
