# Fine-tuning your system

When fine-tuning your ServeRAID settings for optimal performance, consider the applications that you intend to run on your server. ServeRAID settings are usually sensitive to the types of applications running on the server, not the server workload or the number of users using the server. You must investigate your application's design, especially its input/output behavior, to make your decision.

When configuring your ServeRAID controller, your server application environment can influence the following:

- The RAID level you select for your server
- The controller stripe-unit size setting
- The write-back cache mode setting
