DMAs Superclustering

Note

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 page 395.

If you’re planning to form a supercluster, we encourage you to upgrade to the latest version before doing so.

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 DMA System” on page 24.

Superclustering is not supported in Maximum security mode. See “The Consequences of Enabling Maximum Security Mode” on page 54.

DMAs

The DMAs page lets you create, view, and manage a supercluster of Polycom DMA systems (see “About Superclustering” on page 227).

If the system you’re logged into is not 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 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 joined it, and that data becomes the shared supercluster data store.

•Add the system to an existing supercluster by pointing it to one of the existing clusters in the supercluster. The system you’re logged into becomes one of the clusters in that supercluster, and its local data store is largely replaced by a copy of the shared supercluster data store.
