Are storage vendors squeezing dedupe?

As the first vendor to make data deduplication a key piece of the backup picture, Data Domain has benefitted most from the dedupe craze. And now it has the most at stake when deduplication becomes mainstream. If all the major storage vendors offer deduplication, there goes at least part of Data Domain’s edge.

That’s not lost on Data Domain CEO Frank Slootman. He sees NetApp’s decision to build deduplication into its operating system and use it for primary data, and the move by other large disk and tape┬ávendors to put dedupe into their virtual tape libraries as part of a strategy to marginalize the technology.

“NetApp’s and EMC’s fundamental strategy is to make deduplication go away as a separate technology,” Slootman said “NetApp has been giving away their deduplication, and we think EMC [through an OEM deal with Quantum] will fully charge for storage but give away dedupe. They don’t want dedupe to be a separate business, or even a technology in its own right.”

Slootman says he’s not worried, though. He sees the biggest benefit of deduplication as an alternative to VTLs, and claims many new Data Domain customers use deduplication to replace virtual tape rather than enhance it. He calls deduplication for VTLs a “bolt-on” technology, where Data Domain built its appliances specifically for dedupe.

And he maintains that deduplication doesn’t work for primary storage. It’s not a technical issue, but a strategic one.

“Primary data lives for short periods of time, why dedupe that?” he said. “It doesn’t live long enough to get any benefit to reducing its size. If data doesn’t mutate, it should be spun off primary storage anyway. It should go to cheaper storage. It’s the stuff that doesn’t change that mounts a huge challenge for data centers. You can’t throw it away, and it’s expensive to keep online.”

    Shootman, should read Shoot-foot. So let's reflect on another Valley start-up and some similiar words "encryption should be honored and not given away like Decru is doing" former CEO of Neoscale, the now, and may they rest in peace defunked encryption for disk and tape company. What Neoscale learned, yes the hard way, and as Frankie will also so learn, and at the expense of his investors, is that dedeup is a feature of the product and not the product. I hope we can all agree NetApp and EMC have made few errors along the way in product judgement. Frank your missing the big picture "customers don't care", they look for the most value in a product.

    @Andrew Mapp, First off, the name is Slootman...not Shootman. DDUP offers customers the most value in a product. NetApp and EMC can't offer the data duplication reduction rates like DDUP does and probably won't because they want to offer a plethora of lesser developed features rather than one stellar product. I think Slootman is taking Google's advice of "Do one thing really, really well and all else will follow." They're offering the best DDUP products on the market and I think they'll be rewarded for it in the long run. -Bensign

    Bennie sounds likes a consultant to DDUP. Is this true?
