Performance Acceleration Module (PAM), an intelligent caching device that can significantly enhance the performance of applications that do a lot of disk-intensive random reads. A recent Tech OnTap article describes both PAM hardware and software including the caching strategies it uses. We go on to introduce Predictive Cache Statistics (PCS) a software tool that can help you determine if your storage systems can benefit from PAM, how much cache you'll need, and how to best configure it.

Check out the article at: http://www.netapp.com/us/communities/tech-ontap/pam.html ... I recently presented on this topic in a Tech OnTap Live User Group so if you're really interested you can also check out the presentation and event recap.

What are your biggest performance concerns? What do you think of PAM? What do you want to know more about?
