Cisco Cisco TelePresence Management Suite (TMS) Version 15 Installation Guide
Setting up a Redundant Deployment
Cisco TMS supports deployment in a redundant configuration, increasing the availability of the application.
This chapter describes the requirements, configuration, and limitations of deploying Cisco TMS in the two supported
redundant scenarios.

It is assumed that the reader has an understanding of Cisco TMS, Cisco TMS installation, and Windows Server operating
systems, as well as an advanced level of understanding of computer networking and network protocols.

Preliminary Information
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. For new deployments, we recommend using an F5 BIG-IP load balancer for
load-balancing IP traffic between the two Cisco TMS servers, therefore this document describes how to deploy Cisco
TMS with an F5 BIG-IP appliance. We also support using a Cisco ACE 4710 Application Control Engine Appliance.
Migrating from the previous redundancy model to this improved model if you are using an ACE load balancer is
described in

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

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 2012.
