Performance Tuner, from Softek Storage Solutions Inc., Vienna, VA., identifies existing, as well as potential, storage bottlenecks and component failures. However, it adds a new capability not commonly found in storage resource management (SRM) suites -- storage administrators can analyze whether different performance metrics are related to each other. For instance, they can analyze whether performance problems on a database server are connected to the saturation of an ISL in their SAN environment.

The ability to look at any two devices and see if there is a causal effect of one on the performance of the other is a unique feature. It's also one that puts users in a position to take an active management role in tuning the performance of the storage network supporting their critical applications.
