IBM Press Room, DS8000 and AMP

Coming back for the last time on the DS8000 announcements, I still want to put in a quick word on the Press Announcement : "IBM Introduces New and Enhanced Enterprise Storage Products Delivering Consolidation, Simplification and Improved Performance". Just because the press announcement mentions an element that's not covered in the announcements themselves : Adaptive Multi-stream Pre-fetching (AMP).
It's described as "a breakthrough caching technology that can enable up to double the throughput and dramatically reduced processing time for tasks such as data backup, batch processing, business intelligence and streaming media". AMP will e.g. make a DB2 table scan from disk perform like it would be from cache. Apparently it's not in the announcements because it was already quietly introduced to the DS8000 earlier this year with a new microcode upgrade. If you want to find out more, on this page from the IBM Almaden Research Center, you'll find an article on AMP.
