Fine-tuning your system

When fine-tuning your controller settings for optimal performance, consider the applications that you intend to run on your %SERVER%. Controller 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 controller, your %SERVER% application environment can influence the following:

• The RAID level you select for your %SERVER%
• The controller stripe size setting
