Comparing Clustering With Conference Controlling - Cisco TelePresence Server 7010 Product User Manual

Comparing clustering with Conference controlling

There are two overlapping concepts for arranging multiple TelePresence Servers. One way is to create a
cluster of TelePresence Servers, in which one is master and up to three are slaves; the other option is to
nominate one or more additional TelePresence Serverto be under the control of a TelePresence Server
called the Conference controller.
These two concepts are not mutually exclusive, and you can mix them when you arrange multiple
TelePresence Servers. The following rules apply:
There is only ever one Conference controller in a system of controlled TelePresence Servers.
n
If there is only one TelePresence Server in a system, then that one must be the Conference controller.
n
One or more clusters may be controlled by another TelePresence Server; the cluster does not need to
n
be the controller.
If a cluster is to be the Conference controller, then the master blade must be the Conference controller;
n
a slave blade can never be a Conference controller.

the Conference controller.
This table summarizes the differences between the two arrangements:

Comparison Clustering notes
value
Hardware Clustering is only possible on Cisco
support TelePresence Server MSE 8710 blades.
You can not cluster Cisco TelePresence
Server 7000 series servers.
Licensing Requires a Cluster support feature key,
copied to each blade in the cluster.
Co-location Clustered blades must reside in the same
MSE 8000 chassis.
Load Yes
balancing
allowed
Pooled screen Yes
licenses
Resource The master may allocate resources from
allocation one clustered TelePresence Server to a
conference hosted on another.
This means that the maximum conference
size is limited either by the pooled number
of licenses, or by the available capacity of
the whole cluster - whichever is consumed
first by the conference.

Conference controller notes
Conference controller functionality is in all
TelePresence Servers and can be used
between Cisco TS MSE 8710 blades and
Cisco TS 7000 series servers; a blade can
control a server or a server can control a
blade.
Does not require a feature key.
A Conference controller can control remote
TelePresence Servers.
Yes
Yes
The Conference controller may only allocate
resources to a conference on a server-local
basis; that is, the maximum conference size is
limited to the number of participants
supported by the TelePresence Server that
the Conference controller allocates to the
conference.
