Cisco Unified MeetingPlace Web Conferencing Load Balancing Algorithm

The current data-conferencing (DC) load balancing algorithm is as follows:

X = 0.5 * (CPUPercent * 0.6 + MemPercent * 0.4) + DCLoad * DCLoad, where the values for the factors are as follows:

•CPUPercent—The value of the particular resource’s usage on the web server as reported by Windows. This value ranges from 0 to 1 as a percent, for example, if 50%, then 0.5.

•MemPercent—The value of the particular resource’s usage on the web server as reported by Windows. This value ranges from 0 to 1 as a percent.

•DCLoad—The percent of the total number of web or data conferencing (DC) users. This value ranges from 0 to 1 as a percent.

•X—The load balancing factor. The X value is calculated for each server, and the server with the lowest score hosts the meeting.

Suggestions for a Robust Cisco Unified MeetingPlace System

To ensure a robust system with redundancy and failover, we recommend that you have the following:

•An internal web cluster

•An external web cluster

•Multiple remote SQL Servers in the form of an SQL farm

•Remote storage location with RAID5 and a comprehensive backup policy

About Installing Cisco Unified MeetingPlace Web Conferencing Release 5.3 in a Load Balancing Configuration for Video-Enabled Systems

Cisco Unified MeetingPlace Web Conferencing limits video functionality to one web server. It is important to consider this limitation when configuring load balancing in video-enabled systems.

Before you configure Cisco Unified MeetingPlace Web Conferencing load balancing in video-enabled systems, you should understand the following concepts:

•Default Behavior of Load Balancing in Video-Enabled Systems, page 4-6

•Video Meetings in Segmented Meeting Access Deployments, page 4-7

•SQL Server Considerations, page 4-7

•End-User Considerations, page 4-8

Default Behavior of Load Balancing in Video-Enabled Systems

If your Cisco Unified MeetingPlace Audio Server system is licensed for video, all of the web servers connected to it will display video-related fields. These fields appear on the following pages for those users who have video scheduling privileges and allow such users to schedule their meetings from any web server:
