Hardware Resources

Hardware resources for each Siebel Server computer, particularly the CPU (processors) and memory, are a factor in how many concurrent users can be supported for each Siebel Application Object Manager component. For example, a four-processor computer has twice the resources of a two-processor computer and can potentially support twice as many concurrent users. Key hardware resources for Siebel Application Object Manager performance include:

• CPU (processors). The number of processor cores in the CPU for the server computer, and the rating of these processors.

• Memory. The amount of RAM, and whether it can accommodate users without excessive paging.

Disk I/O and network capacity are other important hardware factors, but they do not affect Siebel Application Object Manager tuning. They do significantly affect performance for the Siebel database and the Siebel File System, which can severely impact the overall user response time.

The total number of processor cores (alternatively, the total number of computers with a given number of processors) that you can devote to supporting Siebel Application Object Manager components will determine the total number of concurrent users.
