At appropriate times in the project lifecycle, you can request a Server Sizing study from your Professional Services Project Manager or a IBM® Sales Executive. This study starts with the Sterling Selling and Fulfillment Foundation Server Sizing Questionnaire. IBM Performance Engineering creates a sizing document that provides an estimated processor, memory, and network requirement for the standard/baseline Sterling Selling and Fulfillment Foundation. You need to factor in additional requirements such as other workloads on the same node (for example, additional third party software, customization, performance monitors, and so forth).
