Purpose
This is a general deployment guideline for load balancing Microsoft
Terminal Services with Coyote Point Systems Equalizer™. This deployment
guideline assumes the reader is familiar with the general functionality of
both Equalizer and Microsoft Windows Server 2000, 2003, and 2008.
This guideline is broken into sections that describe how to configure
Equalizer and Microsoft Terminal Server (MSTS)in the
following configurations:
- MSTS 2000, 2003, and 2008 server farms that do not use Session
Directory/Session Broker
- MSTS 2003 and 2008 server farms that use IP-based session redirection
with Session Directory/Session Broker
- MSTS 2008 server farms that use token-based session redirection with Session
Directory or Session Broker
The final deployment scenario includes a Treminal Services specific Server
Agent that can be used in any Terminal Services configuration to communicate
server status information to Equalizer.
Benefits
- Improve MSTS Server or application availability and uptime
- Reduce single points of failure for your MSTS servers or applications
- Automated recovery from MSTS Server failures
- Improve MSTS Server performance
- Load balancing ensures more consistent server and application response
- Improve hardware utilization by sending new MSTS application requests
to the servers with the fewest connections in the application farm
- Improve deployment flexibility
- No single subnet requirement for MSTS deployments as required by
Microsoft Network Load Balancer
Prerequisites / Components
- Microsoft Terminal Services running on Windows Server Standard,
Advanced or Enterprise 2003 or 2008
- Coyote Point Systems Equalizer model E250si or greater, software
version 7.2.4d or greater. The steps defined in this guideline reference an
Equalizer running version 8.5.0b of software. If you are configuring a
different version of Equalizer and you are unfamiliar with the
corresponding steps for your version, please reference the Equalizer
administration guide available in the Help menu of your Equalizer
management interface.
