This is a great point and is an important reminder to all readers that testing is vital when it comes to deduplication solutions. Thank you for the comment.

You missed the achilles heel of the DL3D though: replication performance. My company purchased two 1500's last year to use in a replicated environment. We've had no problem with ingestion performance and are seeing 28:1 deduplication rates. Sadly though, we've found out the hard way they will only replicate at 40-60 megabits per second on average, and as the tag pool grows that number drops considerably. We are currently replicating at only 20mbs. EMC tech support says these units are performing "as they should and better than some". Simply put, the units cannot replicate fast enough to be useful in a replicated environment. Good blog. You missed the achilles heel of the DL3D though: replication performance.
