DATA CENTER and CAMPUS NETWORKS DEPLOYMENT GUIDE
Deploying Brocade Networks with Microsoft Lync Server 2010 34 of 52
Server Architecture
Given the size of the company, Fabrikam has decided to centralize the deployment of the Microsoft Lync Server
2010 servers. The company wants to make sure that full redundancy is built into all layers of the Microsoft Lync
Server 2010 deployment to ensure no single point of network failure. The company has settled on this deployment:
• Demilitarized Zone (DMZ)
– Edge Servers: Two Edge Servers are deployed to service external clients residing outside the
internal network. Microsoft Lync Server 2010 Edge Servers provide multiple roles such as an
Access Edge Server, Web Conferencing Edge Server, A/V Edge Server, and Reverse Proxy Server. If
demands increase on these servers, then these roles will be split into separate servers. The Edge
Server sits behind the Brocade ServerIron ADX hardware load balancer to provide redundancy,
security, and reliability.
• Internal
– Director Servers: Director Servers are used for external user authentication and to pass requests
to the Front End Servers. The Director Servers are also load balanced to distribute the load and
provide redundancy.
– Front End Servers: Fabrikam has decided to consolidate many roles on the Front End Servers,
including voice, IM, presence, and conferencing. If the Front End Servers become overburdened,
then these roles can be moved to dedicated servers.
– Monitoring Server: Fabrikam has decided to install a single Monitoring Server that collects metrics
from the Microsoft Lync Server 2010 clients, to provide a QoE score.
– Survivable Branch Appliance: Fabrikam has decided to place SBAs in San Francisco and Austin to
provide local authentication and provide higher availability.
Summary
Leveraging both Brocade products and Microsoft Lync Server 2010, Fabrikam met and exceeded all of their initial
goals. ROI benefits were seen immediately and, at the same time, end-user satisfaction has risen to a new level due
to the performance enhancements of Microsoft Lync Server 2010 and the Brocade infrastructure. End users
embraced the fact that Microsoft Lync Server 2010 simplified communications by blending services that used to be
managed separately into a single platform, providing connection to anyone at any time over any type of device.
The network team was delighted to see how easy it was to configure and set up a Brocade environment. They feel
confident knowing that the network can scale to meet the needs of their most demanding users. The Brocade
networking products exceeded the network performance standards required for an optimal Microsoft Lync Server
2010 experience and have proven to integrate seamlessly at all levels in the network.
