与 Lync Server 2010 中一样,Lync Server 2013 中大多数服务器角色的主要高可用性方案都基于通过池进行的服务器冗余。As in Lync Server 2010, the main high availability scheme for most server roles in Lync Server 2013 is based on server redundancy via pooling. 如果运行特定服务器角色的服务器发生故障,那么池中运行同一角色的其他服务器将接纳该服务器的负荷。If a server running a certain server role fails, the other servers in the pool running the same role take the load of that server. 这适用于前端服务器、边缘服务器、中介服务器和控制器。This applies to Front End Servers, Edge Servers, Mediation Servers, and Directors.

Lync Server 2013 为前端池添加了新的灾难恢复措施,具体方法是将服务器的地理位置 dispersement 引入两个数据中心,以在一个整体池或站点停机时提供服务的延续。Lync Server 2013 adds new disaster recovery measures for Front End pools by introducing geographical dispersement of your servers into two data centers to provide continuation of service should one entire pool or site go down.

Lync Server 2013 还通过支持针对后端数据库的同步 SQL 镜像,从而增强了后端服务器高可用性。Lync Server 2013 also enhances Back End Server high availability, by supporting synchronous SQL mirroring for your Back End databases.

本节对这些主要的高可用性和灾难恢复功能进行了说明,还介绍了为其他服务器角色实现高可用性和灾难恢复所需执行的步骤。This section explains these major high availability and disaster recovery features, and also covers what steps you can take for high availability and disaster recovery for your other server roles as well.
