Purpose
This is a general deployment guideline for Microsoft Office Communications
Server 2007 and Coyote Point Systems Equalizer™. This deployment
guideline assumes the reader is familiar with the general functionality of
both Equalizer and Microsoft Office Communications Server (MS-OCS).
This guideline describes in detail how to configure Equalizer and MS-OCS
in an Enterprise configuration, consisting of four identical front-end
servers connected to a separate dedicated Microsoft SQL Server 2005 back-end
database.
This basic configuration can be similarly expanded to provide load
balancing and application acceleration in an expanded Enterprise
Configuration, where Equalizer would be used in front of multiple Access
edge servers, A/V edge servers, CWA application servers, and Directors.
Benefits
-
Distribute traffic efficiently from the front-end servers to the server pool.
Equalizers consider server availability, load, response time, and other
user-configured performance metrics when selecting a server for incoming
client connections.
-
Increase application uptime and maximize server farm utilization.
By performing sophisticated and customizable health checks to the servers
and the Microsoft Office Communications Server 2007, Equalizer quickly
identifies resource outages in real time and re-directs client connections
to other available servers.
-
Adjust server capacity on demand without impacting applications and client
connections.
When demand grows, IT engineers can simply slide.in new server resources and
configure Equalizer to use the new servers for client connections.
-
Perform intelligent switching of client requests to appropriate
servers based on application content.
Application switching eliminates the need to replicate content and
application functions on all
servers, and optimizes overall resource utilization, application
performance and availability.
-
Ensure that a
client stays with one real server so all real time information is preserved
as the client continues to communicate across several application ports.
Once a client connects to a server, successive transactions from the client
are directed to the same server.
The power of performance delivered by Equalizer ensures that your
applications provide the best end-user response time and scalability at
both Layer 4 and Layer 7, using sticky connections and cookie persistence.
