I can't find your older DD2200 forum topic, the link is dead from the review. But now that there are flash enabled DataDomain systems, do you think you can sweet talk DellEMC into getting one in the labs? Specifically the DD6300 or similar system?
I would like to see the effects of flash used for metadata, in regards to Veeam restores, VDP performance, and general performance improvements. They are claiming big restore improvements, which has always been an issue for products like Veeam and CVLT and DD used together. Not that it was a limitation by EMC, but more so how those products do lots of random IO on the restore process, that punishes DataDomain, which doesn't do random IO well at all.
