Beyond being a druid, I am a Storage Architect with experience with arrays from HDS, NetApp, Compaq/HP, and EMC. This will be my space to talk a little about the things I see and the effect they will have on the industry.

There was some confusion in the industry, as NetApp has a deduplication engine already (what Data Domain is famous for). The NetApp engine however, causes the performance to half while engaged.
In addition, there is talk that Data Domain was working on a production array with inline deduplication (Most deduplication is done...
