Planning for Metropolitan Site Resiliency
Topic Last Modified: 2011-03-03
If you require Microsoft Lync Server 2010 communications software to be always available, even in the event of a severe disaster at one geographical location in your organization, you can follow the guidelines in this section to create a topology that offers metropolitan site resiliency.
In this topology, Lync Server 2010 pools span two geographically separate locations. In such a topology, even catastrophic server failure in one location would not seriously disrupt usage, because all connection requests would automatically be directed to servers in the same pool but at the second location. The site resiliency solution described in this section is designed specifically for this split-pool topology and is supported by Microsoft subject to the constraints mentioned in Findings and Recommendations.
If your environment does not meet the requirements described in this document, For recommendations about providing resiliency for your Enterprise Voice workload, see Planning for Enterprise Voice Resiliency.
Unless specifically stated otherwise, all server roles have been installed according to the product documentation. For details, see Deployment in the Deployment documentation.
- The Metropolitan Site Resiliency Solution provides an overview of the tested and supported site resiliency solution.
- Test Methodology describes the testing topology, expected behavior, and test results.
- Findings and Recommendations provides practical guidance for deploying your own failover solution.
