The following table lists the hardware requirements for running Windchill ESI. The first row of this table lists the minimum server hardware requirements recommended by both PTC and TIBCO, assuming that all components are installed on the same physical machine and the machine is used exclusively for Windchill ESI.

The preceding table also lists hardware requirements if the components are installed on separate servers. Since TIBCO's architecture is very flexible and highly scalable, you can deploy all the EAI software components on a single physical server or separately on different servers. If you are a large, multi-national organization, you might consider installing BusinessWorks, Adapter for Oracle, EMS Server, each on different servers traversing Wide Area Network (WAN) links, and including fail-over servers for high availability. Also, you can deploy adapter instances on multiple servers to facilitate concurrent product structure data-publishing transactions.

While following these recommendations, keep in mind that these are only rough guidelines. Proper hardware sizing involves not just using technology but also practical, field experience. We encourage you to work carefully with your systems integrator to determine your unique business requirements and to take into account factors such as your site location, anticipated data volumes, and high availability requirements so you can adjust the hardware sizing accordingly. We strongly recommend you first test the performance of the integrated solution to identify bottlenecks and to make appropriate adjustments before you start usingWindchill ESI in a live production environment.
