Chalk Talk – QoS Considerations for Virtualized Cisco Unified Communications

So, I decided to write about a much coveted topic – QoS Considerations for Virtualized Cisco Unified Communications. This article was published in Cisco Technical Services Newsletter of May 2014.

Here’s an excerpt from the article:

Cisco Collaboration (aka Cisco Unified Communications) solutions have come a long way since the conception of IP Telephony. With advancements in technology and the need to reduce economic and environmental impact, virtualization is well on way to become the core of all major technologies including Unified Communications. Cisco Collaboration solutions are now fully supported on Cisco UCS, with backend Nexus, storage, and Fibre Channel over Ethernet (FCoE) based systems complementing the next gen solutions.

However, with inclusion and dependency on virtualized environments the issue of Quality of Service (QoS) remains to be understood as it is no longer physical switches, NICs, or application instances that are deployed; it is virtual switches (for example Nexus 1000V), virtual NICs, and virtual machines that are deployed as Cisco Collaboration solutions are increasingly virtualized.
