DMA Operations Guide About Superclustering

assign a primary cluster and a backup cluster for each territory. When the primary cluster is online, it controls the territory and carries out all of the responsibilities belonging to the territory. When the primary cluster is offline, the backup cluster assumes control of the territory and carries out all of the territory’s responsibilities.

A standalone (not superclustered) Polycom DMA system has a single default territory for which it’s the primary cluster (and of course there is no backup). When you join other clusters to it to create a supercluster, it still has that same single default territory, it’s still the primary cluster for the default territory, and there is still no backup cluster. Essentially, one cluster is responsible for everything, and the others do nothing. So immediately after forming a new supercluster, you should do the following:

1If you haven’t already done so, create your site topology data or integrate with a Polycom RealPresence Resource Manager or CMA system to obtain it. See “Site Topology” on page 283.

2Determine how you want to organize your sites into territories in order to best distribute responsibilities and workload among the clusters of your supercluster. A number of strategies are possible. For instance, with a five-cluster supercluster, you could adopt one of the following schemes:

—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.

Note

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 DMA system. You must create the territories needed in the RealPresence Resource Manager or CMA system.

3Create the territories needed, assign functionality responsibilities to the territories, and assign primary and backup clusters to the territories.
