Cisco Cisco TelePresence Management Suite (TMS) Version 15 Maintenance Manual
Preliminary information
Communication with managed systems
Understanding how Cisco TMS communicates with managed systems is key to understanding Cisco TMS
redundancy. For a detailed description see

Supported configurations
For a fully redundant Cisco TMS deployment with an automatic failover process, you must set up two Cisco
TMS servers with a network load balancer (NLB) in front. Cisco recommends using a Cisco ACE 4710
Application Control Engine Appliance for load-balancing IP traffic between the two Cisco TMS servers,
therefore this document describes how to deploy Cisco TMS with an ACE 4710 appliance.

This chapter also describes how to deploy two Cisco TMS servers using a Hot Standby model.
Regardless of which of the two redundancy models you choose to deploy, no more than two Cisco TMS
servers can be used. Deploying more than two Cisco TMS servers in a redundant setup is neither tested nor
supported by Cisco.

Deploying two Cisco TMS servers will increase Cisco TMS availability, but will not in any way increase
Cisco TMS scalability.

Licensing
Only one live database can be used in a redundant Cisco TMS implementation, therefore both servers will
use the same Cisco TMS serial number and the same set of release and option keys.

Database redundancy
Cisco TMS relies heavily on its SQL database, so a fully resilient Cisco TMS solution will also utilize one of
the high-availability technologies offered by SQL Server 2008. Thoroughly documenting SQL Server 2008
high-availability alternatives is beyond the scope of this chapter, but the two relevant SQL Server redundancy
models are briefly discussed in the
