SSD Backup - backup accelerated by or saved to solid state storage

ALL enterprise backup will be solid state by 2020
"The SSD platform represents a bigger market opportunity in the next 5 years than any other type of enterprise software. The winners in SSD software could be as important for infrastructure as Microsoft was for PCs, or Oracle was for databases, or Google was for online search."
the SSD software market is getting ready for a world in which all enterprise data touches SSDs
flash backed DIMMs - a new directory from

Editor:- October 21, 2014 - Although has been writing about flash backed DRAM DIMMs since the first products appeared in the market - I didn't think that subject was important enough before to rate a specific article or market timeline page.

That's unlike memory channel SSDs - which is now 1 of the top 10 SSD subjects viewed by readers after having had its own directory page since April 2013.

However, sometimes a market is defined as much by what it isn't as by what it is.

And so - to help clarify the differences between these 2 types of similar looking storage devices (one of which I think is much more significant than the other - but both of which are important for their respective customers) I have today created a directory page for hybrid DIMMs etc - which will act as the future pivoting point for further related articles.

Coho Data now shipping 2U MicroArray hybrids

Editor:- March 6, 2014 - Coho Data today announced general availability of its first product - a 2U SSD ASAP called the DataStream (an SSDserver 4/E) - which integrates PCIe SSDs, hard drives and a server into a web scale expandable unit (using an internal 52 port 10GbE fabric switch) to implement what the company refers to as a "MicroArray" designed with the philosophy of "Turning Tiering Upside Down (pdf)" to deliver a base building block unit of 180K IOPS performance (4KB).

Editor's comments:- you may judge for yourself the lofty scale of Coho's ambitions by this market soothsayer quote which they integrated in the launch press release - "By 2017, Web-scale IT will be an architectural approach found operating in 50% of Global 2,000 enterprises."

Fusion-io acquires SCSI target IP team

Editor:- March 18, 2013 - Fusion-io announced today that it has acquired another storage software company - ID7 - which had been collaborating on the development of FIO's ION data accelerator software.

ID7 was the primary developer of the SCST (SCSI target subsystem for Linux) that enables replication, thin provisioning, deduplication, high availability, and automatic backup on any Linux server or appliance.

will flash save tape? - flape

Editor:- November 9, 2012 - "Flape" - flash cached tape archive - is a new word discussed in a blog - Flape and Floud - by Steve Kenniston - The Storage Alchemist who says "Over the last two decades I have been in this business, tape has been killed off more than a bad guy in a James Bond movie..."

Editor's comments:- It's interesting to think that flash tiering and caching might extend the life of tape libraries. But in the distant future (2020 timescale) I expect that anyone still using tape cartridges might find when they open them - they have archive SSDs inside emulating the tape media. It was already done long ago for floppy drives. But even SSDs become EOL and cause problems for those trying to support legacy systems.

SSDs or hard drives? - the data forensics differences

Editor:- October 23, 2012 - When you need to retrieve critical unbacked up data from a damaged notebook (which you left in the car when you clambered out the window after realizing that the puddle across the road was much deeper than you first thought) you call the process "data recovery" - but when a court seizes a suspect's notebook to try and retrieve data which may have been deliberately "deleted" - they call it "data forensics" - either way - in the most demanding cases the experts who work on these tasks are the same.

SSD Data Recovery (as opposed to dumb flash memory recovery) is a relatively new market which didn't exist 5 years ago.

A recent article Why SSD Drives Destroy Court Evidence - on a site called - discusses how techniques which are essential to the operation of flash SSDs (such as garbage collection and wear leveling) mean that from the forensic viewpoint SSDs yield up potentially much less deliberately deleted recoverable data than hard drives.

future SSD capacity ratios in the server, SAN and archive

Editor:- September 14, 2012 - Have you ever wondered... how much SSD storage should sit inside servers compared to being located on the SAN? And what about archive storage? Something new to think about in an article inspired by SSD news

1U MLC RamSan accelerates backup window for Penn State University

Editor:- May 15, 2012 - a research group at Penn State University has reduced its backup time from 6 hours (with a 200 drive HDD array) to 1 hour by using a pair of 1U rackmount MLC SSDs (model RamSan-810) from Texas Memory Systems.

"With some of the other 3 solutions we tested, we poked and pried at them for weeks to get the performance where the vendors claimed it should be," said Michael Fenn, systems administrator at Penn State. "With the RamSan, we literally just turned it on and that's all the performance tuning we did. TMS was the best solution largely because of its maturity and performance. It seemed very stable and it just worked out of the box."

HA enterprise SSD arrays

Editor:- January 26, 2012 - due to the growing number of oems in the high availability rackmount SSD market today published a new directory focusing on HA enterprise SSD arrays.

In my past 20 years of publishing enterprise buyers guides - I've developed an instrinct for judging when the market is ready for a new focused directory. Sometimes I've been too early - but with the momentum in the enterprise SSD market and the number of HA SSD vendors already dipping into double digits - I think this is exactly the right time for such a new directory.

university researchers compare SSD and tape archives

Editor:- November 1, 2011 - a recent white paper - Using Storage Class Memory for Archives with DAWN, a Durable Array of Wimpy Nodes (pdf) - written by academics at University of California, Santa Cruz and Stanford University - and published under the auspices of the Storage Systems Research Center compares the long term cost and reliability of solid state archival storage and traditional media - such as tape.

"Our investigation has shown that storage class memories have many characteristics favorable to digital archiving. Despite this, more investigation in several areas is needed in order to fully understand the tradeoffs and feasibility of a storage class memory approach." the article

2.5" SSDs accelerate disaster recovery

Editor:- September 24, 2010 - an update to Intel's SSD Bookmarks - published today on - includes links to a case study in which RAID rebuild times for a real-time education server were reduced from 12 hours to 40 minutes, while response times became 25x faster. the articles

Can you believe the word "reliability" in a 2.5" SSD brand?

Editor:- July 29, 2010 - today published a new article - the cultivation and nurturing of "reliability" in a 2.5" SSD brand.

Reliability is an important factor in many applications which use SSDs. And belief in SSD reliability is a precondition for the emerging SSD backup market. But can you trust an SSD brand just because it claims to be reliable?

As we've seen in recent years - in the rush for the SSD market bubble - many design teams which previously had little or no experience of SSDs were tasked with designing such products - and the result has been successive waves of flaky SSDs and SSDs whose specifications couldn't be relied on to remain stable and in many products quickly degraded in customer sites.

As part of an education series for SSD product marketers - this new case study describes how one company - which didn't have the conventional background to start off with - managed to equate their brand of SSD with reliability in the minds of designers in the embedded systems market. the article

Nimble Storage enters the ASAP market

Editor:- July 15, 2010 - Nimble Storage announced the release of the Nimble CS-Series an iSCSI compatible SSD ASAP which has been optimized for backup and compression performance.

survey shows most users think they can't afford zero loss disaster recovery

Editor:- June 9, 2010 - Axxana today published findings from a survey it funded to understand the role that cost plays in inhibiting user adoption of zero data loss disaster recovery solutions such as its own SSD based solutions.

'This survey has really shown how today's end users still feel that eliminating data loss though a disaster recovery strategy is still out of their budget,' said Eli Efrat, Axxana's CEO. 'Although cost is still an important consideration, the results support our strategy and I am confident that a year from now solutions such as our Phoenix System will have a much bigger foothold in the market because they make zero data loss DR an affordable option.'

Powered by Nimbus' HALO storage OS the systems support iSCSI, NFS, and CIFS protocols and provide inline deduplication (typically 10 to 1), continuous local and remote replication capability in-the-box at no additional cost. Data protection inside the box ensures that no data is lost even with 2 simultaneous blade faults.

reaching for the petabyte SSD

Editor:- March 16, 2010 - previewing the final chapters in the long running SSD vs HDD wars - 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. the article

Solid State Storage Backup - new directory for a new market

Editor:- February 16, 2010 - launched a new directory today for - Solid State Storage Backup.

Although these are still early days for the S3B market - the new page will help you filter out news, articles and messages from the S3B pioneers which otherwise might get lost in the clamor of the SSD market bubble.

"In the early days of the disk to disk backup market the old tape vendors scoffed at the idea that hard disks might one day steal their market. Now most of those old tape dinosaurs are gone and the hard disk backup market reigns supreme" said editor, Zsolt Kerekes.

"Despite that - I expect that most vendors in the D2d / VTL market today will not even be dreaming about the possibility that SSDs will one day transform their own cozy market too. But they urgently need to start having fresh ideas about what backup and recovery are really for? The S3B page will chronicle the news from the nascent Solid State Storage Backup market - and help to accelerate those changes."

ioSafe Launches Disaster Proof Backup SSD

Editor:- January 5, 2010 - ioSafe launched the ioSafe Solo SSD - an ultra rugged USB / eSATA external flash SSD with upto 256GB capacity ($1,250) designed to provide data protection against disasters such as fire, flood, and building collapse.

ioSafe offers a "no questions asked" Data Recovery policy to help customers recover from any data disaster including accidental deletion, virus or physical disaster.

"The new ioSafe Solo SSD is the world's most rugged and versatile desktop external hard drive. It can be used alone or in conjunction with any offsite or online backup strategy to add real time, zero data loss, synchronous disaster protection to any data that sits vulnerable," said ioSafe CEO, Robb Moore.

$9 million Funding Round for flash SSD Enabled SAN Backup

Editor:- November 18, 2009 - Axxana announced it has secured $9 million Series B investment led by Carmel Ventures.

Axxana's existing investors, Gemini Israel Funds and the serial entrepreneur Moshe Yanai, also participated in the round.

The funds will be used to accelerate the adoption of The Phoenix System - the first "Black Box" Enterprise Data Recorder which was demonstrated at EMC World in May 2009.

"Axxana's EDR brings a disruptive solution that is well poised to transform the entire storage replication market and create a whole new category within it," said Ronen Nir, Partner at Carmel Ventures. "We are impressed with Axxana's strong founding team and their achievements so far, including impressive endorsement by leading storage vendors worldwide."

Editor's comments:- Axxana's solution is a lossless data recovery system which sits on the SAN and records data into a rugged flash SSD-enabled, locally situated, data survival box. Although Axxana talks about it "complementing" other types of data protection - such as offsite / online backup my gut feel is that if the product shows itself to be usable and reliable in a wide range of environments - it will set a new standard for backup which will supercede anything possible with rotating disk backup systems or tape.

The clearest explanation is in Axxana's datasheet (pf).

World's Fastest RAM SSD uses flash SSD backup

Editor:- July 22, 2008 - Texas Memory Systems today launched the world's fastest SSD - the RamSan-440,

The RamSan-440 is a 4U rackmount fibre-channel connected RAM SSD with upto 512GB of storage capacity. It can sustain up to 600,000 random IOPS and over 4GB/second of random read or write bandwidth, with latency of less than 15 microseconds.

the RamSan-440 is a 4U RAM SSD delivering 600,000 random IOPS - click for more info

It's the first RAM SSD to use RAIDed flash memory modules for data backup (instead of hard disk) and the first system to incorporate Texas Memory Systems' patented IO2 (Instant-On Input-Output) technology.

In Active Backup mode, the RamSan-440 continuously backs up data to the internal flash array without impacting system performance. The RamSan-440 can back up or restore the entire 512GB of data in just 6 minutes. (That's a process which could take over an hour with HDD backed SSDs of this capacity.)

TMS's patented IO2 technology further improves system availability by making user or application-requested data instantly accessible after the system is powered on.

Solid State Storage Backup (S3B)

S3B - a possible new name for a definitely new storage market................
S3B is a new acronym for Solid State Storage Backup - coined by

It follows the thinking behind "D2d" - which was what disk to disk backup pioneers called their market a decade ago - before spawning further acronyms like VTL.

Why S3B?

In the early phases of this new market - (2010 to 2013) most of the S3B backup will be from hard disk based systems to SSD based backups. But as the storage market progresses (from about 2015 onwards) we'll start to see a significant proportion of the S3B market change its shape to look more like - online-SSD-bulk-storage backing up to nearline-SSD-archive-storage.

That will be SSD to SSD backup.

As it's the next big thing in backup after D2d and as there are a lot of S's in all that solid state storage - and as backup SSDs are going to be different in their nature to existing types of SSDs - I thought "S3B" would be a good way to signal what this new market is really about and the direction it will be heading.

The "B" in S3B is important too! - These new types of SSD based backup solutions will have SSDs which are optimized for different characteristics than the traditional 4 main application types described in our 2005 SSD market penetration model. (Although in the early days of the market the backup SSDs will be cherry picked from what is available for other markets - and will therefore be more expensive.) has been tracking the SSD market longer than any other publication or market research company. And I'm excited that the time now looks right (in February 2010) to maintain the tradition of starting a new directory page for another new subject.

Although these are still early days for the S3B market - this news page will help you filter out the messages from the S3B pioneers which otherwise would get drowned out in the babble of the SSD market bubble.
