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。
