　　1.1 Understand What is Central Site
　　Central Administration Site
　　A central administration site (CAS) is the top site server in the hierarchy. Unlike
　　the other site servers, you cannot assign any clients to the CAS, nor can you install
　　any user-facing site systems roles except from the software update point. A CAS
　　stores client data for all clients in the hierarchy in a SQL Server database called the
　　ConfigMgr site database. The CAS can have multiple primary child sites, all of
　　which send data to the CAS. At the CAS, you also have the Administrator console
　　from which you can manage hierarchy.
　　中心管理站点是在层次结构中的顶端站点服务器。不像其他站点服务器，除了软件分发点之外，你无法给CAS分配任何客户端，你也不能安装任何面向用户的站点系统角色。中心管理站点在称之“ConfigMgr site database”的SQL Server数据库中存储了层次结构中所有客户端的数据。中心管理站点可以有多个主站点，所有主站点发送数据到中心。在中心管理站点，你还拥有管理控制台从中你可以管理层次结构。
　　Question: Do I always need a central administration site?
　　Answer: No, a CAS is needed only when you have more than one primary site in the hierarchy. As a matter of fact, most readers of this book may never need to implement a CAS.
　　问：我总是需要中心管理站点吗？
　　答：不，仅当你在层次结构拥有多个主站点的时候才需要中心管理站点。
　　Question: If needed, when should I install the central administration site?
　　Answer: With R2, you can install a CAS after you have installed a primary site.
　　Prior to Service Pack 1, you had to install the CAS first. With that in mind, there is
　　really no reason to install a CAS upfront as a “just in case solution.” I have seen that done by many customers, and so far none of them needs a CAS.
　　问：如果我需要，我应该在什么时候安装中心管理站点？
　　答：随着R2的发布，你可以在你安装了主站点之后安装中心管理站点。在SP1之前，你必须首先安装中心管理站点。请谨记，前期作为“以防万一”真的没有必要去安装中心管理站点。我见过很多客户完成的项目，到目前为止他们中没有一个需要中心管理站点的。

　　1.2 Understand What is Primary Site
　　Primary Site
　　You always need at least one primary site in the hierarchy. If you do not, there is
　　really no reason for you to finish reading this book or any other ConfigMgr-related
　　book. It’s very simple: without a primary site, you have no working ConfigMgr
　　environment. Clients can be assigned only to a primary site. A primary site stores
　　client data for all clients assigned to the site in a SQL Server database called the
　　ConfigMgr site database. Primary sites have administrative tools, such as the
　　Administrator console, that enable an administrator to manage the site directly.
　　Primary sites can have multiple secondary sites, all of which send data to the
　　primary site.
　　总之在层次结构中你至少需要一个主站点。如果不是的话，对于你来说真的没有必要去完成这本书或者其他相关ConfigMgr的阅读。非常简单，没有主站点，你没有ConfigMgr的工作环境。客户端只能分配到主站点，主站点在称之为“ConfigMgr Site database”的SQL Server数据库中存储了分配到站点的所有客户端的数据。主站点拥有许多管理工具，例如：能够让管理员直接管理主站点的管理工具。主站点可以拥有多个辅助站点，它们中所有都会发送数据到主站点。
　　Question: When do I need more than one primary site?
　　Answer: That’s a good question, and I’m so glad you asked it. Unlike previous
　　versions of ConfigMgr (and SMS), there are not many reasons why you would
　　implement more than one primary site when using ConfigMgr 2012. The main
　　reasons for implementing more than one primary site are:
　　(1)You have more than 100,000 users, which is the recommended maximum
　　number for a primary site.
　　(2)For political reasons, you are required to have a primary site in each data
　　center.
　　问：我什么时候需要多个主站点？
　　答：这是一个好问题，你这样问我很高兴。不像先前的ConfigMgr版本，当你使用ConfigMgr2012的时候，你为什么要实施多个主站点并没有许多的原因。实施多个主站点的原因是：
　　(1) 你拥有超过10万用户，这是主站点的推荐的最大数量。
　　(2) 出于政治的原因，在每个数据中心要求你拥有一个主站点。
　　1.3 Understand What is Secondary Site
　　Secondary Site
　　Unlike previous versions of ConfigMgr and SMS, a secondary site now also
　　requires a SQL Server database. It doesn’t have to be a Standard or Enterprise
　　version, as the SQL Server Express edition will do just fine. If you don’t have a
　　local database, the secondary site installation can take care of that and install a
　　version of SQL Server Express. The secondary site is always a child site of the
　　primary site and thus managed through the ConfigMgr console connected to the
　　primary site. The secondary site forwards the information it gathers from clients,
　　such as computer inventory data and system status information, to its parent site.
　　The primary site then stores the data of both the primary and secondary sites in the
　　site database. Secondary sites are particularly useful for remote locations where
　　you need links where you need to control the bandwidth.
　　不像先前的ConfigMgr和SMS版本，现在辅助站点同样要求SQLServer数据库。其不必是一个标准版或企业版，因为SQLServer Express（SQL免费版）就能胜任。如果你没有本地数据库，辅助站点安装可以处理这一点，及安装一个SQL Server Express版本。辅助站点始终是主站点子站点，从而通过ConfigMgr控制台连接到主站点来管理它。辅助站点发送其从客户端收集的信息给主站点，例如：计算机数据清单和系统状态信息。然后主站点在其站点数据同时存储了主站点和辅助站点的数据。 辅助站点对于你需要控制带宽链接的远程站点尤其有用。
　　Question: Are there any rules of thumb for when I should implement a secondary
　　site at a remote location?
　　Answer: I only recommend installing a secondary site at remote locations and only
　　if one of the following statements is true:
　　1.The remote location has more than 500 clients.
　　2.You need to compress traffic going to the site.
　　3.You need to control the upward flowing traffic.
　　4.You need a local management point.
　　5.You need a local software update point.
　　问：对于我何时需要在远程站点实施一个辅助站点有没有一些经验法则？
　　答：在远程位置我仅推荐安装一个辅助站点，并且仅当以下陈述其中一个为真的时候

• 　　远程站点超过500客户端
  
• 　　你需要站点之间压缩流量
  
• 　　你需要控制上传的流量
  
• 　　你需要一个本地管理点
  
• 　　你需要一个本地软件更新点
