In an article for Enterprise Storage Forum, Paul Shread comments on the positive reviews that various deduplication technologies got at Storage Decisions from analysts and end users. He suggests that less than 10% of attendees were using deduplication already, but that others were inspired by their experience and would be using it soon.

Paul goes on to quote me, saying I “didn’t think primary data de-duplication technology was ready for prime time just yet.” I absolutely did say these words, but I am not sure if my point came across.

I’ve recently expounded about the benefits of deduplication technology, but have warned that it might not be all it’s cracked up to be in primary storage environments. By “primary” I mean those storage environments serving mission-critical applications. Although dedupe works great for backup and archiving, the random I/O, low latency, and high throughput of primary storage (and especially virtualized servers) might be too much for current systems. And as of now, only NetApp, Riverbed (soon), and startups greenBytes (see my story) and Ocarina (more on them another time) were willing to go on record with me as supporting deduplication of primary storage.

So what I meant was that deduplication is not yet ready for prime time in primary storage applications. No one should hesitate to use the technology for backup or archiving at this point, but make sure you do a thorough evaluation of the specific product you are selecting to make sure it delivers the performance you require!

This is a follow-up to my story, De-Duplication Goes Mainstream

Although deduplication of storage is nothing new, with Data Domain and other making hay with the technique for years, it has never been ready for prime time - reduction of active primary storage applications like email and databases. Instead, deduplication has been relegated to second- or third-tier status, deduplicating archives and backup data. But change is in the air, and deduplication vendors are starting to bustle towards the bright lights of primary storage.

TechTarget’s Storage magazine today announced the winners of their annual Products of the Year awards, and it’s an impressive array of technologies. Although I did not contribute to the voting this year, I heartily endorse the outcomes!

Overall, I was impressed with many of these products this last year, but certainly CommVault, HDS, ProStor, Xsigo, and Akorri (winners all) stood out with important products. I too was surprised to see the absence of some heavyweights: Symantec’s strength in archiving and backup didn’t net them an award, and both Emulex and QLogic were skipped for the 8 Gb FC market. EMC was overlooked, too, but I’m certain that will be remedied for 2008 after the flurry of excellent new products announced these last few months.

Backup Software

• Winners: CommVault’s Simpana 7.0 - an impressive product that brings a very wide range of data protection features in an integrated package. They’d be in my top three! Next was the intriguing RecoverGuard from Continuity Software, a product which intrigues me. Finally, Yosemite’s amazingly priced FileKeeper Professional took bronze - I definitely would have put this up there, too!
• Strong contenders: EVault’s solution would have been my pick since it effectively tackles a real need - mobile and SMB data protection! Also, Symantec’s strong NetBackup 6.5 upgrade deserved more attention.

Backup Hardware

• Winners: NEC’s HydraStor HS8 isn’t a platform I’m familiar with - I’ll have to take the judges at their word! But I can’t argue with silver and bronze winners, Copan and ProStor’s cool RDX - both are truly revolutionary products and deserve the spotlight.
• Strong contenders: I would definitely have added Gresham’s Clareti VTL to the list - it’s much more than “just a VTL” and I hope it gets some more attention!

Disk and Disk Subsystems

• Winners: Seagate’s Momentus 5400 FDE.2 deserves considerable attention, bringing built-in hardware encryption to the mobile data market - every mobile disk should have this technology! NetApp’s FAS2000 (silver) is nice enough, but I was much more impressed with the bronze-winning USP V from HDS this year.
• Strong contenders: I would have given the USP V the top prize for 2007, but I can’t argue with the little Seagate disk. The AMCC 3ware 9600 RAID adapter deserves some attention, too.

Storage Management Software

• Winners: Akorri’s BalancePoint (gold) impresses me much like bronze-winning Onaro’s Application Insight does. Both make the big leap from “storage” to “application data”, and both are worthy winners. I’ve never used the silver-winning Finisar NetWisdom product, but it looks like others are impressed with it.
• Strong contenders: This was a crowded field, and Symantec, WysDM, Quantum StorNext, and the rest probably came close. I agree with the Akorri placing, but would have picked one of these instead of the potentially mis-categorized Finisar product.

Networking Equipment

• Winners: Xsigo took the top honors with their InfiniBand-based VP780 platform. This is truly a next-generation product, and it is getting serious attention and traction, and deserved a spot on the list! Riverbed’s excellent Optimization System (silver) also deserved its ranking, but I’m not familiar enough with the Storwize product to know if it’s truly bronze-worthy.
• Strong contenders: I would have tipped either QLogic or Emulex’s 8 Gb offerings for a spot. Despite my jokes, 8 Gb FC is an important element of the modern SAN and both companies have carved out a compelling product, but apparently neither shipped in volume until this month…
