就像在 Lync Server 2010 中,Lync Server 2013 中的大部分伺服器角色的主要高可用性架構,都是透過 pooling server 冗余度為基礎。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. 如果執行特定伺服器角色的伺服器失敗,集區中執行相同角色的其他伺服器就會接手該伺服器的負載。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. 這適用於前端伺服器、Edge Server、中繼伺服器和 Director。This applies to Front End Servers, Edge Servers, Mediation Servers, and Directors.

Lync Server 2013 新增前端集區的新的嚴重損壞修復方法,方法是將伺服器的地理 dispersement 引入兩個資料中心,以在整個集區或網站中斷時,提供服務的連續執行。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 也可支援後端資料庫的同步 SQL 鏡像,增強後端伺服器的高可用性。Lync Server 2013 also enhances Back End Server high availability, by supporting synchronous SQL mirroring for your Back End databases.

本節說明這些主要高可用性和災害復原功能,另外也會說明您可以針對其他伺服器角色的高可用性和災害復原採取哪些步驟。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.
