NetApp is way ahead on this

ASIS is VERY different from Data Domain. Since NetApp's gateway can sit in front of EMC, HDS, IBM and HP disk (since when is EMC/HDS 'cheap and dirty disk????)... AS PRIMARY DISK then there is a real deduplication advantage.

Data Domain dedupes ONLY backup data and usually to their own disk (yes they sell a gateway, but just try and buy one... you'd have better luck selling your Lehman stock). Data Domain is a one trick pony. Once people wise up that deduping your primary storage eliminates the need to dedupe your backup data, they'll be a bust.

Riverbed looks like a 'me too' product... we'll have to wait to see the specs

NetApp is way ahead on this ?

A couple of points, firstly you must buy into the Netapp filesystem, essentially making your array a slave to Netapp's NAS implementation. Just because Netapp are pitching this as a supported solution, I don't see any of the other vendors clamouring to sign joint support agreements around this. Who carries the can if it all goes tits up.

This only works for certain usage cases and certain backup environments which also potentially effects the granularity of restore. In addition the Jury is definately still very much out on whether deduping both primary and secondary copies is such a good idea.

NetApp way ahead

Yes, of course... and the vendors who only perform the disk functions whine about this because they want to control the WHOLE environment and resist any open storage platforms. It's a weak argument if the configuration meets or exceeds the end-user expectations.

Yes, of course... why would EMC certify NetApp as a gateway when EMC wants to own your whole environment and make you buy just EMC? In an open environment, the end-user has to exercise some authority over the role each vendor's piece plays in their environment. If EMC (or any vendor) balks at just being disk to a NetAp gateway, the end-user needs to walk away from EMC and work with a vendor that will cooperate... and trust me... EMC will cooperate if they think they are out of the solution.

>"This only works for certain usage cases"

Give me a scenario where it doesn't work.

Ignorance is bliss

The main point here is that the author as well as Riverbed and the quoted SVP have not done their homework. NetApp supports deduplication on primary as well as backup and archive, and has done so for a very long time. Recently NetApp was recognized by Dave Russell (Research VP at Gartner) as the market leader in data deduplication, bar none. Data ONTAP provides this capability at the volume level (turned on, turned off, scheduled) for free. Through using the NetApp V-Series, non-NetApp arrays can now be deduplicated in the primary environment as well (as pointed out by others above).

So what is the news here?

If you want to use industry standard backup tools for something like a database against a LUN rather than an NDMP dump :-)
