Deploying DSCP QoS On Server 2003 R2 and Server 2008 R2

This is a brief post to summarize my experiences with deploying quality of service in a recent deployment.

In this engagement, the customer had existing OCS 2007 R2 infrastructure, these were running Server 2003 R2 with the latest service pack, and were running on HP hardware with Teamed NICS for redundancy, not load balancing.

When attempting to deploy packet tagging on the servers using the QoS Packet Scheduler and related policies, packets would not tag at all. When breaking the NIC Team packets would tag, and on any servers without a teamed NIC the same policies worked fine. This was identified as a known issue with 2003 R2 and Teamed NICS.

The good news, is that while we are upgrading to Lync Server 2010 their new servers are running Server 2008 R2 and on similar hardware with Teamed NICS. As of today we have tested QoS deployed using the packet scheduler and related policies and it does work with the Team.

If you like it, share it!
