Resource Capacities in AVC CP, SVC and Mixed Mode Conferences
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
tables show the actual resource capacity utilization for both CP only and mixed CP and SVC conferences

MCU Resource Management by RealPresence Resource Manager, Polycom CMA and Polycom RealPresence DMA System
When the RealPresence Resource Manager, Polycom CMA and Polycom RealPresence DMA system are
part of the solution, following a request by the RealPresence Resource Manager 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, 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.In Flexible Resource
Capacity Mode, CMA/DMA receive information about how many Video (CIF) and Audio resources are
occupied per conference or MCU according the request type sent by the CMA and DMA.
●Occupied resources are resources that are connected to ongoing conferences. Disconnected
endpoints in an ongoing conference are not counted as occupied resources.
●An ongoing conference that does not include participants and the Send Content to Legacy Endpoints
option is disabled does not occupy resources. If the Send Content to Legacy Endpoints option is
enabled, the conference occupies one SD resource.
●The Collaboration Server is unaware of the resource usage split between the CMA and
RealPresence DMA system.
Port Usage Threshold
The Collaboration Server can be set to alert the administrator to potential port capacity shortages. A
capacity usage threshold can be set as a percentage of the total number of licensed ports in the system.
When the threshold is exceeded, a System Alert is generated.
The default port capacity usage threshold is 80%.
The administrator can monitor the MCU’s port capacity usage via the Port Gauge in the Status Bar of the
Collaboration Server Web Client.
