MCU Pools
The MCU Pools list shows the MCU pools, or logical groupings of media servers, that are defined in the
Polycom RealPresence DMA system. In a superclustered system, this list is the same on all clusters in the
supercluster. A pool may group MCUs based on location, capability, or some other factor.
Every conference room (VMR) is associated with an MCU pool order (either by direct assignment, via the
user’s enterprise group membership, or from the system default). The pool(s) to which an MCU belongs,
and the pool order(s) to which a pool belongs, are used to determine which MCU is used to host a
conference. For details of how an MCU is chosen for a conference, see MCU Pool Orders.
You can use various criteria for organizing MCUs into pools, depending on how you want the MCU
resources allocated for conferencing. For instance:
● You could put all MCUs in a specific site or domain into a pool. Then, assign a pool order to all users
in that site or domain (via group membership) ensuring that their conferences are preferentially
routed to MCUs in that pool.
● You could put one or more MCUs into a pool to be used only by executives, and put that pool into a
pool order associated only with those executives’ conference rooms.
● You could put MCUs with special capabilities into a pool, and put that pool into a pool order associated
only with custom conference rooms requiring those capabilities.
Note: MCU pools vs. MCU zones
MCU pools were called MCU zones in earlier versions of the Polycom RealPresence DMA system.
The name was changed to avoid confusion with the concept of gatekeeper zones.
Note: MCU pool orders
If you have a Polycom RealPresence Resource Manager system that uses the RealPresence DMA
system API to schedule conferences on the RealPresence DMA system’s conferencing resources
(MCU pools), you must create MCU pools and pool orders specifically for the use of the RealPresence
Resource Manager system. The pool orders should be named in such a way that:
• They appear at the top of the pool order list presented in the RealPresence Resource Manager
system.
• Users of that system will understand that they should choose one of those pool orders.
If the RealPresence Resource Manager system is also going to be used to directly schedule
conferences on MCUs, those MCUs should not be part of the conferencing resources (MCU pools)
available to the RealPresence DMA system.
Note: MCUs and ISDN gateway selection
MCU pools and pool orders are not used to select an ISDN gateway for simplified gateway dialing.
See ISDN Gateway Selection Process.
