Sizing process

Hardware

During the implementation of Infor LN ensure you select suitable hardware to avoid problems at a later stage of the project. Undersized hardware that cannot be upgraded, or oversized hardware can stop the implementation due to budget problems. Therefore, you must consider sizing carefully during the implementation.

Final sizing

A final sizing can only be performed if all implementation aspects are known. In a pre-sales situation, there is often only high level information about the usage of the application. In this case, a pre-sales sizing can be done to have an estimate on hardware costs.

Sizing verification

A sizing verification can be done after going live with the first implementation. With the sizing verification, all assumptions made during the sizing can be verified. If required, the sizing can be adjusted to better support the following implementations.

Stress test

Performance problems tend to appear shortly before going live with an implementation. It is advised that you perform a stress test shortly before going live, to verify if the actual performance meets the requirements.

The following table shows the sizing stages and the tools, and the documents or services supporting them.

Step	Phase	Tooling / documentation / service	Notes
1	Collect key sizing figures from customer	Configuration and planning questionnaire Configuration and planning questionnaire for upgrades	For upgrades use information from existing applications
2	Optional: customer specific benchmark to determine load of specific functionality	Customer specific benchmark	Only for large/complex/business critical customers
3	Size the hardware	Sizing Guide / E-Sizing assistant (web based)
4	Deliver sizing and deployment information to the customer	Sizing Template / Sizing White Paper
5	Optional: stress test	N/A	Timely before going live to be able to solve problems
6	Optional: do a sizing verification at the customer site to adjust sizing figures	Sizing verification	Only for large/complex/business critical customers After going live

Steps 1, 3 and 4 are an iterative process. In a pre-sales phase, an initial sizing can be done to determine hardware costs. In an after-sales phase an more detailed sizing can be developed.

Step 6 can be done at multiple implementation stages, such as after going live for each customer location.
