Conclusion

We have tested a new-generation controller from LSI that supports the new SAS 6Gbps standard. The controller has shown some indubitable progress over its predecessors and offers excellent performance at database operations (especially with mirror-based arrays). On the other hand, the new SAS interface is going to be the most demanded for streaming loads. And it is at streaming loads that we cannot see impressive results. Other controllers delivered better performance on SAS 3Gbps.

The adaptive caching algorithms are the most memorable thing for us, though. It may be an excellent idea for real-life applications, but is a real headache for hardware testers. :)
