Note: Clusters vs. Superclusters
Technically, a standalone Polycom RealPresence DMA system (two-server or single-server) is a
supercluster that contains one cluster. All the system configuration and other data that’s shared
across a supercluster is kept in the same data store. At any time, another Polycom RealPresence
DMA system can be integrated with it to create a two-cluster supercluster that shares its data store.
It’s important to understand the difference between two co-located servers forming a single
RealPresence DMA system (cluster) and two geographically distributed RealPresence DMA clusters
(single-server or two-server) joined into a supercluster.
A single two-server RealPresence DMA system (cluster) has the following characteristics:
•A single shared virtual IP address and FQDN, which switches from one server to the other when
necessary to provide local redundancy and fault tolerance.
•A single management interface and set of local settings.
•Ability to manage a single territory, with no territory management backup.
•A single set of Call Server and Conference Manager responsibilities.
A supercluster consisting of two RealPresence DMA clusters (single-server or two-server) has the
following characteristics:
•Separate IP addresses and FQDNs for each cluster.
•Separate management interfaces and sets of local settings for each cluster.
•Ability for each cluster to manage its own territory, with another cluster able to serve as backup for
that territory.
Different Call Server and Conference Manager responsibilities for each territory and thus each cluster.
