## Performance tuning your system

When tuning your ServeRAID settings for optimal performance, consider the applications 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.

When configuring your ServeRAID controller, your server application environment helps determine the controller stripe-unit size setting.

Note: You must use the ServeRAID Manager in startable-CD mode to change these settings.

Environment | Stripe-unit size
Groupware | 16 KB
Transaction processing database | 16 KB
Decision support database | 16 KB
Thin client environments | 8 KB
File server (Microsoft® Windows NT®) | 16 KB
File server (Novell NetWare) | 16 KB
File server (Other) | 8 KB
Web server | 8 KB
Other | Default

Your application environment can also influence the RAID level you select for your server. You must investigate your application's design, especially its input/output behavior, to make your decision.
