Superclustering
Polycom, Inc. 227
Create four territories, assign a primary cluster for each, and assign the fifth cluster as backup for
all four.
Create five territories, assign a primary cluster for each, and make each cluster the backup for
one of the other territories.
Use some hybrid of the above that best suits your enterprise network’s distribution of sites, users,
and traffic.
Keep in mind that only three territories can host conference rooms.
3Create the territories needed, assign functionality responsibilities to the territories, and assign
primary and backup clusters to the territories.

RealPresence DMAs
The RealPresence DMAs page lets you create, view, and manage a supercluster of Polycom
RealPresence DMA systems (see About Superclustering on page 226).
If the system you’re logged into is not (and has not been) part of a supercluster, the list contains only that
system. The Join Supercluster command lets you:
●Create a new supercluster by pointing it to another free-standing (not superclustered) Polycom
RealPresence DMA system. Both systems become clusters in the new supercluster. The system
you’re logged into has its local data store largely replaced by a copy of the data store from the system
to which you pointed it. The data from that other system becomes the shared supercluster data store.
Note: Resource Management Integration
If you’ve integrated with a Polycom RealPresence Resource Manager or CMA system, site topology
data comes from that system and can’t be edited in the RealPresence DMA system. You must create
the territories needed in the RealPresence Resource Manager or CMA system.
Note: Supercluster Software Versions Must Match
All the clusters in a supercluster must be running compatible software versions. Patch releases of the
same major version will generally be compatible, but major version upgrades will not be compatible.
Major version software upgrades of a supercluster take careful planning. See Incompatible Software
Version Supercluster Upgrades on page386.
If you’re planning to form a supercluster, we encourage you to upgrade to the latest version before
doing so.
Note: Create Required DNS Records
The host names (virtual and physical) of every cluster in the supercluster must be resolvable by all the
other clusters. For a superclustered system, A/AAAA records on your DNS server(s) for each physical
host name, physical IP address, and virtual host name are mandatory. See Add Required DNS
Records for the Polycom RealPresence DMA System on page30.
Superclustering is not supported in Maximum security mode. See The Consequences of Enabling
Maximum Security Mode on page55.
