Editor's pick of D2d and VTL companies
If I listed all the companies with a claim to being in the disk backup market - then you'd get a long list of over 500 vendors - and that would be simply from data mining the backup software ISVs, hard disk makers and disk array oems already listed on other pages here on storagesearch.com

That wouldn't be very useful.

So, instead, I've looked back at the last 10 years of news stories which actually made it to this D2d page (out of the many thousands of storage news stories we published (and that was distilled down from over 100,000 storage news stories in my email or which I saw on the web.)

Out of all that brew I've chosen less than 20 companies which seemed to say something worthwhile or consistent about this subject and they appear below as a useful starting point for your continuing storage search.

Are MLC SSDs Safe in Enterprise Apps?
Backing up your data to a solid state disk (or SSD RAID Array) may sound like a crazy idea today...

...but no more so than the idea - 10 years ago - that disk to disk backup would one day replace tape.

I've been backing up my data to flash storage (in rotation with hard disk storage) for about 5 years. There have been less failures in the flash backup media than the hard drives - which translates to a lower TCO. But I'll keep using more than one type of media - because I'm paranoid about losing data.

SSDs cost more per gigabyte than hard drives, but that cost gap is closing fast.

New generations of MLC SSDs offer 2x the capacity at the same silicon price, and some companies are talking about 4x devices - with 8x maybe just a year or so away.

Most SSD oems claim that flash SSDs have much better MTBF than hard drives. While that may be true - the uncorrectable data corruption rates in some types of SSD may be orders of magnitude worse than SLC SSDs, and worse than HDDs.

And the theoretical operating life of SSDs varies by 100 to 1 between different brands and technologies of SSD.

Storage reliability is more than the longevity of the storage media. It's about survival of the data.

This article shows the technical reasons why multi level cell flash SSDs may work OK in notebooks and PDAs - but may not work satisfactorily in a rackmount datacenter environment. ...read the article

Is Deduplication of Data Safe? - and More Deduplication FAQs
One of the problems with disk backup is scalability.

For small and medium sized companies the speed and convenience of disk backup outweighs any other considerations - and in most cases is cheaper than the alternatives. But if you're backing up data associated with tens of thousands of internal users - then eventually the cost of the disk media (compared to traditional tape - even with tape's intrinsic lumbering speed, high service costs and unreliability) may start to become an important feasibility issue.
dedupe faqs article
In theory that's where deduplication comes in - because (moving beyond that other must-have D2d technology - compression) it offers the promise of saving more unique data to less disks.

But is dedupe scalable? Is it safe? And what about performance?

The ultimate dedupe faqs is a good starting point to learning more. ...read the article

SEPATON article on tape dinosaurs

Editor:- August 30, 2010 - Jon Mills, Director of European operations at SEPATON recently published an article - Tape - the T Rex of backup? - which provides anthropological comparisons between tape libraries and these popular creatures.

I guess it takes one soon-to-be-extinct dinosoar to recognize another. My own view is that hard disk based backup will eventually be replaced by solid state backup. So enjoy chewing the spinning magnetic leaves while they last.


10,000x more reliable than RAID?

Editor:- August 26, 2010 - Amplidata claims that its BitSpread technology is 10,000x more reliable than current RAID based technologies and requires 3x less storage.

Is another new way of fixing reliability problems in hard disk arrays worth the effort just as we approach the end of the hard disk market's life? - I doubt it. See why in - this way to the petabyte SSD.


Overland launches tape library patent suit

Editor:- August 20, 2010 - Overland Storage announced it is suing BDT AG - for alledged infringement of tape library related patents.

"We owe it to our shareholders and our customers to protect the technology investments we have made throughout the years," said Eric Kelly, President and CEO of Overland Storage. "We believe our technologies are one of the driving forces behind the demand for tape storage solutions today. Our patented technologies allow us and others to bring to market products and solutions that are more reliable, more secure and more efficient."

Editor's comments:- Tape library market revenue has halved in the past 10 years. (2000 tape library revenue was $2 billion according to Freeman Reports .) But that strengthens the case for defending each remaining slice and crumb.


Compression-past company acquired by IBM

Editor:- July 29, 2010 - Storewiz announced a definitive agreement to be acquired by IBM.

Editor's comments:- Storewiz's real-time compression technology was predicated on a legacy model in which there were no SSDs (compression-past).

This was a short sighted market view - because SSD IOPS will enable new types of storage array economics - as discussed in my article Reaching for the petabyte SSD (compression-future).

IBM's acquisition may have short term tactical benefits for the company - and help them collect some patent license fees but is otherwise irrelevant.


NetApp's Jay Kidd joins board at ProStor

Editor:- June 29, 2010 - ProStor Systems announced today the appointment of Jay Kidd to its Board of Directors.

Mr. Kidd's accomplishments span over 30 years in key leadership roles at many high profile multi-national storage, networking, and computing companies with a strong emphasis in product strategy and development, marketing, and business operations. Mr. Kidd is currently serving as senior VP, Storage Solutions Group and Product Strategy and Development at Network Appliance.

Prior to joining NetApp, he held the position of CTO and VP of product management at Brocade, where he played a key role in developing and implementing the Brocade product road map, including infrastructure and strategic evangelism.


Nasuni offers $5,000 to successful espiones

Editor:- June 22, 2010 - I have to hand it to the marketers at Nasuni - they've come up with a clever promotion scheme.

Cynics (aka experienced computer realists) are worried that cloud storage may be inscecure - right?

Nasuni say - that the 1st person who can reveal the contents of a file which they have made visible here can win $5,000.

"We're aware that many businesses are dubious about cloud storage for security reasons," said Nasuni CEO and co-founder Andres Rodriguez. "Data leakage is a major concern. With cloud storage, you have to entrust your data to an outside party, and your data is swimming around in the cloud with other customers' data. Intuitively, it seems risky. Customers are smart to be wary. But we've built a system that protects against these risks. We're confident that Nasuni can keep your data safe in the cloud, and we are willing to go the distance to prove it."

Editor's comments:- the clock is ticking. After 30 days - the company will donate the "unwon" money to a good cause.

Who's going to crack it 1st? - the Russians? or Chinese? Or has an NSA spook read the message already by the time you see this posting - but won't claim the prize - because that would be revealing too much.

I bought the 1st UK edition of the Cuckoo's Egg - and I can still remember the thrill of reading how a barely noticeable security intrusion was traced over many modem hops and international routes and much elapsed time and effort to reveal a real-life espionage. Storage Security


Re tape's protracted demise

Editor:- June 16, 2010 - How tape dies is the latest blog from StorageMojo, Robin Harris.

Tape market's body is still twitching - so it's not technically a corpse (yet) - but the life signs are getting smaller. See also:- Historic Milestones in Enterprise Disk Backup

will free terabyte disks extend the life of the hard disk market?

Editor:- June 9, 2010 - Could terabyte hard drives be given away free? - is the subject of a new blog published this week on StorageSearch.com

In it I suggest that the biggest future market for high capacity consumer HDDs isn't backup and that a new market model may be a better business. ...read the article


3.5" HDDs will store 10 terabytes by 2015

Editor:- June 7, 2010 - Coughlin Associates has published its 14th annual HDD Capital Equipment and Technology Report (pdf) (189 pages / $7,000).

Fueling the need for more capex the authors anticipate that disk drive volumes will more than double - from about 670M in 2010 to 1.4B in 2015 - and that technology developments will result in 10TB 3.5" HDDs and 1TB 1.8" drives.

Editor's comments:- in my article - this way to the Petabyte SSD - I said that the highest capacity 2.5" - bulk archive SSDs - (a product category which doesn't exist yet) could store 50TB in 2016 - which would be 10x the best hard drives - and with better R/W performance and a lower power footprint.

I also said that a key difference would be that the SSD could use wire-speed compression (with minimal impact on R/W performance) to deliver even more virtual storage capacity.

It's the combination of SSD's unique factors which will make the difference in big disk backup systems at the end of this decade - not just the raw media cost / density which transfixes many market commentators. Will there still be a market for hard drives? - Yes. And much bigger volumes than today. But not in the datacenter or the enterprise. More from me on this subject later.


the new dedupe? - Permabit inside

Editor:- June 7, 2010 - Permabit today announced that its high performance data deduplication software has achieved multiple design wins with leading OEMs who will embed it in storage solutions coming to market by the end of 2010.

Permabit says its Albireo dedupe architecture scales to petabytes of network storage (FC, iSCSI, NFS, or CIFS), has application aware tuning and can deliver upto 800MB/s ingest on dual quad core processors with an extremely small memory footprint.


5 Cloud Storage Tips from Nasuni

Editor:- May 13, 2010 - Nasuni recently published a guide to the top 5 issues you should consider when looking at cloud storage.

This is a very hype-laden market - which has taken 10 years to get nowhere substantial very fast - but I suppose others might (wrongly) say something similar about the 35 years it's taken for the SSD market to get seriously started.

Because I have grown suspicious about all new storage software companies - I let this one sit in my inbox for a few days before looking at it in more detail.. But the points made seem quite sensible. ...read the article

Editor:- March 24, 2010 - Toshiba today announced it is sampling its highest capacity 2.5" hard drives - with 1TB in a 12.5mm high package spinning at 5,400 RPM.

Hard disk capacities in the 2.5" size have doubled in less than 2 years. You can see how HDD and SSD capacities have grown in the past decade in this article.


Digitiliti Launches Virtual Corporate Library

Editor:- March 22, 2010 - Digitiliti today announced availability of its DigiLIBE a multi-functional continuous VTL, dedupe, compression, ediscovery appliance which automatically captures and archives new data from the time it is created and sanitizes it at the end of its policy mandated life.

Pricing starts at about $20,000 for a 3TB information director and $3 per GB archived after dedupe and compression, plus $100 per client.


reaching for the petabyte SSD

Editor:- March 16, 2010 - previewing the final chapters in the long running SSD vs HDD wars - StorageSearch.com today published an industry changing new article - SSDs - reaching for the Petabyte.

What will the PB SSD look like? When will it appear? What technology problems do SSD designers have to solve to get there? What about the storage architecture that the PB SSD fits into? How much electrical power will it consume? And... you may be curious - how much will it cost?

All these questions and more - are discussed and answered in this article which - I anticipate - will inspire product managers and company founders to create completely new types of SSDs. ...read the article


Imation renews RDX license to hard disk afterlife

Editor:- March 10, 2010 - Imation today announced it has extended its RDX (removable hard disk) license agreement with ProStor Systems through 2020.

Imation also announced that it has invested $5 million to help advance ProStor's disk backup technology.

Editor's coments:- RDX was unveiled in November 2005. Today's announcement takes the license agreement to beyond the expected lifetime of the hard disk market. However, SSD backup will also be viable in the same form factor.
