RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 Administrator’s Guide

●Flexible Resource Capacity™ – This is the default allocation mode that is used in all versions and
can be used in all Card Configuration Modes and applies to all Conferencing Modes (SVC and AVC
conferencing). The resources are only set to audio and video as a pool and the system allocates the
resources according to the connecting endpoints. This mode offers flexibility in resource allocation
and is available in MPMx and MPMRx Card Configuration Modes.
In Flexible Resource Capacity mode, in MPMx and MPMRx Card Configuration Modes, the maximum
number of resources is based on the system license, regardless of the hardware configuration of the
MCU. These resources are allocated as CIF resources by default.
Example: If the MCU is licensed for 80 video resources, but only one Media card is currently installed
in the MCU, the system lets you allocate 80 ports although only 40 video resources are available for
participant connection. (However, an active alarm will be added to the Active Alarms list indicating a
resource deficiency).
Video/Voice Port Configuration - MPMRx
Although the Video/Voice Configuration dialog box is displayed for Collaboration Servers 2000/4000
with MPMRx media cards installed, Video/Voice Configuration is not supported.
These MCUs and the Collaboration Server 1800 will allocate the same amount of system resources to
voice (audio) participants, as those allocated to CIF video participants. For more information see Resource
Reports .
Video/Voice Port Configuration - MPMx
The Video/Voice Port Configuration dialog box enables you to configure the resources per resource type
using Flexible Resource Capacity Mode if the MCU has MPMx media cards installed.

Flexible Resource Capacity Mode

Flexible Resource Capacity is the default mode for MPMx media cards.
All resources are initially allocated as HD720p30 video ports. The administrator can allocate some or all of
these resources as Voice resources and let the system allocate the remaining Video resources
automatically as participants connect to conferences. The number of resources automatically allocated by
the system resources per endpoint is according to the participant’s endpoint type, capabilities and line rate.
From Version 8.1, only the MPMx Media Card and Card Configuration Mode are supported.
From Version 8.1, Fixed Resource Capacity mode is disabled and cannot be selected in the
Video/Voice Port Configuration.
If Fixed Resource Capacity mode was active at the time of an upgrade, Flexible Resource Capacity
mode will automatically be enabled, the settings from the last time Flexible Resource Capacity mode
active on the Collaboration Server are implemented when the upgrade is complete.
If the system runs out of voice ports, voice endpoints cannot connect to available video ports.
Conversely, video endpoints cannot connect to available voice ports.
