1、Content&nbsp;Server&nbsp;可以划分为若干站点&nbsp;，至少需要划分一个主站点。相同的文件可以同时存储在所有不同的站点,&nbsp;也可以存储在一个或多个站点上。<br>2、不同的站点之间独立管理自己的数据存储&nbsp;，用于管理和存储文件内容。&nbsp;数据存储之间互相独立，互不干扰。<br>3、站点按照功能分为以下两类：<br><b>主</b>站点：<b>存储系统元数据和数据</b>。对外提供完整的&nbsp;SequoiaCM&nbsp;业务功能。同时为其它&nbsp;分站点提供元数据服务。一个最简的&nbsp;SequoiaCM&nbsp;系统仅需要一个主站点&nbsp;即可，不需要其它&nbsp;分站点。<br><b>分</b>站点：&nbsp;仅用于<b>存储数据</b>。必须依赖主站点的元数据存储服务才能对外提供正常的业务功能。<br>

Content&nbsp;Server&nbsp;负责&nbsp;SequoiaCM&nbsp;系统的主要<b>业务</b>逻辑。支持如下功能：<br>•&nbsp;文件的<b>读、写、删</b>功能<br>•&nbsp;文件跨站点<b>缓存</b>功能<br>•&nbsp;文件的<b>迁移</b>功能<br>•&nbsp;文件的<b>清理</b>功能<br>•&nbsp;单文件<b>缓存</b>功能<br>一个Content&nbsp;Server&nbsp;只能归属于一个站点。一个站点下可以有若干个&nbsp;Content&nbsp;Server&nbsp;，Content&nbsp;Server&nbsp;之间互相独立，互相不依赖。Content&nbsp;Server&nbsp;作为独立进程运行在服务器上，用户通过驱动连接&nbsp;Content&nbsp;Server&nbsp;，并使用&nbsp;SequoiaCM&nbsp;的功能。<br>

工作区用于承载具体业务的逻辑单元，可以存储业务相关性较大的文件等元素。工作区一般跟用户业务一一对应。<br>工作区的元数据存储在主站点中，数据可以存储在多个分站点中，根据具体业务需求指定。&nbsp; &nbsp;<br>

文件是工作区的一个最基本的存储单元，用于存储文件数据。<br>文件的元数据和数据的分布继承于其对应的工作区，可以分布于不同的站点中。<br>文件<b>上传</b>：<br>1、客户端通过驱动连接站点分站点的&nbsp;Content&nbsp;Server进行文件上传<br>2、文件数据通过&nbsp;Content&nbsp;Server写入到分站点的数据库中<br>3、文件的元数据信息通过&nbsp;Content&nbsp;Server写入到主站点中<br>文件<b>下载</b>（<b>本地</b>站点）：<br>客户端通过驱动连接站点分站点的&nbsp;Content&nbsp;Server进行文件下载<br>1、Content&nbsp;Server&nbsp;从主站点中获取到文件的元数据<br>2、Content&nbsp;Server从本地站点的数据库中读取文件数据<br>3、Content&nbsp;Server返回数据给客户端<br>文件<b>下载</b>（<b>异地</b>站点）：<br>客户端通过驱动连接站点&nbsp;分站点的&nbsp;Content&nbsp;Server进行文件下载。<br>1、Content&nbsp;Server从&nbsp;主站点中获取到文件的元数据，文件数据存储在异步站点分站点中；<br>2、Content&nbsp;Server从本地站点的数据库中读取文件数据；<br>3、Content&nbsp;Server返回数据给主站点的&nbsp;Content&nbsp;Server；<br>4、主站点的&nbsp;Content&nbsp;Server&nbsp;将数据返回给&nbsp;分站点的Content&nbsp;Server；<br>5、分站点Content&nbsp;Server将数据返回给客户端。<br>

<b>scmadmin&nbsp;</b>工具提供了管理&nbsp;SequoiaCM&nbsp;业务配置的功能。如用户、站点、工作区和Content

<b>scmctl</b>&nbsp;工具提供节点管理相关的功能

<b>scminspect</b>&nbsp;工具提供检查指定工作区在某个站点下&nbsp;LOB&nbsp;的残留情况。
