Understanding clustering

A cluster is a group of blades, hosted in the same Cisco TelePresence MSE 8000 chassis, that are linked
together to behave as a single unit. You can configure and manage clusters using the Cisco TelePresence
Supervisor MSE 8050.
A cluster provides the combined screen count of all the blades in the cluster. This larger screen count
provides you with the flexibility to set up conferences with more participants or several smaller conferences.
For more information about screen licenses, see
capacity [p.126].
Overview of a Cisco TelePresence Server MSE 8710 cluster
Cisco TelePresence Server MSE 8710 blades running software version 2 or later support clustering.
Currently you can cluster up to four blades, with one blade being the master and the others being slaves.
The master can allocate the cluster's licenses as necessary, for example, all in one large conference, or
distributed across several smaller conferences. See
conferencing capacity [p.126]
Master TelePresence Servers
The screen licenses allocated to each of the TelePresence Servers in a cluster are "inherited" by the master;
all the capacity in the cluster is controlled by the master. You must control the cluster's functionality via the
master, using either its web interface or its API.
All calls between the cluster and endpoints are made by the master.
Slave TelePresence Servers
Slave TelePresence Servers do not display the full web interface. Some settings pages are available, for
example, to configure the network and logging settings, and to upgrade the software.
Similarly, a slave TelePresence Server will not respond to the full complement of API commands. For more
information, refer to the relevant API documentation.
Upgrading clustered TelePresence Servers
When you need to upgrade the TelePresence Server software on all units in a cluster, first upload the new
software images to each unit in the cluster and then restart the master. The slaves will automatically restart
and the upgrade will be completed.
General points
Some points to note about clustering:
The Supervisor must be running software version 2.1 or above to configure clustering.
n
All TelePresence Servers in a cluster must be running identical software builds.
n
Each blade in the cluster must have the Cluster support feature key.
