Cisco Cisco Computer Telephony Integration Option 8.5 Release Notes

All agents connected to a Cisco Data Store must be running the same release of 
Siebel (i.e., all Siebel 7.5.3, all Siebel 7.0.5, or all Siebel 6). Cisco Data Store does 
not support configurations in which agents are running different releases of 
Siebel.

With the Siebel 7 driver, Cisco Data Store supports a maximum of 20,000 agents. 
(The Cisco Data Store capacity with the Siebel 6 driver is much lower; see the 
Release Notes for Service Release 3 for Cisco CTI Software Release 4.7 for 
specifics.)

The actual number of agents your Cisco Data Store will be able to support may 
be less than 20,000 agents, and will depend on the following factors.

Number of transfer calls per second.

Amount of data transferred between agents and Cisco Data Store

CPU processor speed

Memory size

It is important to ensure that CPU usage does not regularly exceed 50% during 
normal operation of the server when fully loaded. Since performance is affected 
by many factors including CPU capacity, it is important to monitor your system 
to determine the maximum number of agents you can support without exceeding 
the 50% CPU usage limit.

For example, Cisco testing has determined that Cisco Data Store can support 
20,000 agents in the following configuration:

Cisco Data Store residing on a Windows 2000 system that meets the 
recommended hardware requirements stated in the Bill of Materials for Cisco 
Enterprise Contact Routing document at 

http://www.cisco.com/univercd/cc/td/doc/product/icm/index.htm

.

Simplex system (Cisco Data Store does not support fault tolerance)

Cisco Data Store trace mask is set to 0x7

200 calls per second

A call ratio of 60% standard calls and 40% transfer calls
