General Guidelines for Contact Center Sizing

The following table shows the contact center sizing categories based on the number of base objects being monitored and the daily call volume.

Contact Center Sizing Categories
Sizing Category Number of Agents Number of Agent Groups Number of Queues Daily Call Volume
Small Fewer than 500 Fewer than 50 Fewer than 50 Of the order of tens of thousands
Medium Fewer than 5000 Fewer than 400 Fewer than 1000 Up to 500,000
Large Fewer than 30,000 Fewer than 1000 Fewer than 8000 Up to 4 million

Example Configurations for Contact Centers based on Size

The following are examples of possible configurations based on contact center size. You can use these examples as general guidelines when deploying the full Advisors suite, particularly for Advisors releases prior to 8.1.5. The examples are based on servers running Windows operating systems, but – starting with Advisors release 8.5.0 – you can deploy Advisors components on Red Hat Enterprise Linux 5. See the Pulse Advisors page in the Genesys Supported Operating Environment Reference Guide for a list of supported operating systems.

See also "Capacity, Measurement, and Sample Architecture" in this guide, which provides performance information from tested environments running Advisors release 8.1.5 software. The "Capacity, Measurement, and Sample Architecture" section discusses each Advisors component separately (Contact Center Advisor (CCAdv), Workforce Advisor (WA), and Frontline Advisor (FA)) and provides specific deployment architectures for each to successfully achieve 1500 concurrent dashboard users.

In the configurations listed below, Frontline Advisor and Agent Advisor (FAAA) running on a Cisco platform using the Advisors Cisco Adapter (ACA) has not been shown. If you have a Cisco environment and wish to use FAAA, a separate instance of FAAA needs to be installed along with an instance of the ACA. Hence, the hardware requirements shown in this section for FA and the Advisors Genesys Adapter (AGA) for FA will need to be duplicated.

Important
Agent Advisor and the Contact Center Advisor–Mobile Edition applications are mentioned in the tables on this page. Be aware that both are discontinued starting with Advisors release 8.5.2.

Small Contact Center Size

The following table shows an example of the architecture for a small-sized Contact Center. In this architecture, there is no separate server for the Web tier. Apache is deployed on one of the servers hosting the applications.

Small Contact Center
Server Number Application Component(s) Processor(s) Memory Hard Drive Space
1 Advisors Platform, Contact Center Advisor XML Generator, and Advisors Web services (including Resource Management Console) Quad-core 2.0 GHz+ 4 GB 10 GB
2 Contact Center Advisor–Mobile Edition Dual-core 2.0 GHz+ 4 GB 5 GB
3 Apache, Advisors Platform, Frontline Advisor, and Advisors Genesys Adapter Quad-core 2.0 GHz+ 4 GB 10 GB
4 Databases Dual Quad-core 2.0 GHz+ 4 GB+ 30 GB
5 Supervisor Desktop Service (for Resource Management Console) Quad-core 2.0 GHz+ 4 GB+ 10 GB

Medium Contact Center Size

The following table shows an example of the architecture for a medium-sized Contact Center. In this architecture, you separate the major application, database, and Apache installations.

Medium Contact Center
Server Number Application Component(s) Processor(s) Memory Hard Drive Space
1 Apache Web Server Dual-core 1.86 GHz+ 512+ MB 5 GB
2 Advisors Platform and Advisors Web services (including Resource Management Console) Dual Quad-core 2.0 GHz+ 4 GB 10 GB
3 Advisors Platform and Workforce Advisor Dual Quad-core 2.0 GHz+ 4 GB 10 GB
4 Contact Center Advisor XML Generator Dual Quad-core 2.0 GHz+ 4 GB 10 GB
5 Contact Center Advisor–Mobile Edition Dual-core 2.0 GHz+ 2 GB 5 GB
6 Advisors Genesys Adapter (for Contact Center Advisor) and Advisors Genesys Adapter (for Frontline Advisor) Dual Quad-core 2.0 GHz+ 4 GB 10 GB
7 Advisors Platform and Frontline Advisor Dual Quad-core 2.0 GHz+ 4 GB 10 GB
8 Databases Dual Quad-core 2.0 GHz+ 4 GB+ 50 GB
9 Supervisor Desktop Service (for Resource Management Console) Quad-core 2.0 GHz+ 6 GB+ 10 GB

Large Contact Center Size

The following table shows an example of the architecture for a large-sized Contact Center.

Large Contact Center
Server Number Application Component(s) Processor(s) Memory Hard Drive Space
1 Apache Web Server Dual-core 1.86 GHz+ 8 GB 5 GB
2 Advisors Platform and Advisors Web services (including Resource Management Console) Dual Quad-core 2.83 GHz+ 16 GB 20 GB
3 Advisors Platform and Workforce Advisor Dual Quad-core 2.83 GHz+ 16 GB 20 GB
4 Contact Center Advisor XML Generator Dual Quad-core 2.83 GHz+ 16 GB 20 GB
5 Contact Center Advisor–Mobile Edition Dual-core 2.0 GHz+ 4 GB 5 GB
6 Advisors Genesys Adapter (for Contact Center Advisor) Dual Quad-core 2.83 GHz+ 16 GB 20 GB
7 Advisors Genesys Adapter (for Frontline Advisor) Dual Quad-core 2.83 GHz+ 16 GB 20 GB
8 Advisors Platform and Frontline Advisor Dual Quad-core 2.83 GHz+ 16 GB 10 GB
9 Databases Dual Quad-core 3.0 GHz+ 32 GB 80 GB
10 Supervisor Desktop Service (for Resource Management Console) Quad-core 3.0 GHz+ 8 GB+ 10 GB

Memory Allocation Recommendations

When an Advisors server records out-of-memory errors in its log file, consider changing the memory allocation for the server. Monitor the errors and, if the problem with memory persists, experiment with higher values. After you change the memory allocation, continue to monitor the server and the log file to ensure that you have configured acceptable values. For example, the Advisors server might fail to start if you set the memory allocation too high because the memory requested from the operating system is simply not available. The server will report an error in the log file if it cannot start because the requested memory is unavailable.

Genesys recommends the following values as the maximum memory setting values for the CATALINA_OPTS and JAVA_OPTS variables:

  • Small Contact Center: 4 000
  • Medium Contact Center: 8 000
  • Large Contact Center: 12 000

For additional information, see Change Memory Allocation in the Genesys Pulse Advisors Deployment Guide.
