Chapter 19-Collaboration Server Administration and Utilities
Polycom, Inc. 19-11
When viewing the Collaboration Server resource report for mixed CP and SVC conferences,
the resource allocations are described in AVC HD720p30 units. A port ratio of 1 AVC HD
port will equal 2 AVC SD ports, which equals 3 SVC ports (in a non-mixed conference).
When the Collaboration Server is reporting the available capacity, it will appropriately
round up the remaining capacity to the nearest whole value of available ports. For example,
one SVC endpoint in a conference is equal to 1/3 of the resource value. The resource report
displays this as one full resource used. Two SVC endpoints is equal to 2/3 of the resource
value. Therefore, the resource report displays this as one full resource used, and so forth.
The following table explains the actual resource capacity utilization for both CP only and
mixed CP and SVC conferences:
* Resources are consumed at this rate only after the conference contains mixed endpoints.

MCU Resource Management by RealPresence Resource Manager (XMA),

Polycom CMA and Polycom RealPresence DMA System

When the RealPresence Resource Manager (XMA), Polycom CMA and Polycom
RealPresence DMA system are part of the solution, following a request by the RealPresence
Resource Manager (XMA), Polycom CMA or Polycom RealPresence DMA system, the MCU
will send updates on resource usage to both CMA and DMA, with each application
updating its own resource usage for the MCU. This provides better management of the
Collaboration Server resources by the RealPresence Resource Manager (XMA), Polycom CMA
and Polycom RealPresence DMA system.
Guidelines
• Following requests sent by CMA and RealPresence DMA system, the Collaboration Server
will send the number of occupied resources for a conference or total for the MCU.
• Occupied resources are resources that are connected to ongoing conferences.
Disconnected endpoints in an ongoing conference are not counted as occupied
resources.
