Sizing the Siebel deployment

Installing Siebel CRM for personal evaluation or prototyping is one thing, providing a stable and high performing enterprise application to hundreds or thousands of end users is quite another challenge.

In certain phases of the Siebel CRM implementation project, consultants and IT staff will have to deliver a sizing document that provides insight into the expected number of end users and their concurrent sessions.

The necessary amount of hardware units and software components is dependent on these main factors:

• Maximum number of concurrent user sessions
• Expected volume of data and indexes
• Hardware vendor
• Operating system type
• Database vendor
• Network bandwidth
• High-availability and failover requirements

Each of these has to be considered and evaluated. Customers typically rely on the services of experienced staff from either Oracle or consulting corporations to accomplish this.
