DMA OperationsGuide About Superclustering
228 Polycom, Inc.
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 jo in other c lusters t o it to cre ate 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 page283.
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.
3Create the territories needed, assign functionality responsibilities to the
territories, and assign primary and backup clusters to the territories.
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.
