another $150 million for Pure Storage

"the fastest growing storage company in history"

Editor:- August 29, 2013 - Pure Storage today -announced that it has closed an oversubscribed $150 million Series E funding round with institutional investors which brings the company's total capital raise to $245 million. The company has shipped hundreds of units of its FlashArrays (fast-enough rackmount SSDs) to a diverse global customer base and claims it's one of the fastest growing storage companies in the industry's history.

Editor's comments:- in 2001 I started an annual series which listed the fastest growing storage companies - based on revenue growth. I ended the series in 2007/8 when the credit crunch kicked in. But you can still see many of the archived articles.

In the last year of the series there were 3 storage companies which reported over 300% year on year revenue growth. Today Pure Storage is hinting that its year on year revenue growth is north of 400%.

LinkedIn uses Virident SSDs

Editor:- August 28, 2013 - Virident Systems today announced that LinkedIn is a customer of its PCIe SSDs.

Editor's comments:- In the early days of the SSD market it was usual for SSD companies and their customers to be secretive about their relationships - especially when users were getting spectacular commercial results from using SSD acceleration.

Typically users would tell me - they didn't want their competitors knowing how they had achieved what they were doing using SSDs.

And in those days vendors were mostly secretive about the identity of their customers too - because they had invested high costs in educating users about SSDs and having done that didn't want their known competitors knocking on SSD-friendly doors.

Now everyone has heard about SSDs (as near as makes any difference) - and the SSD education problem for vendors has shifted to being - that potential customers learned about SSDs from someone else. - So that means SSD vendors have to adapt their sales message to fitting into the SSD schema and market frameworks which customers already have in their heads - rather than assuming they will be regarded as the font of all SSD wisdom.

And another thing which changed in the market in recent years - as more SSD companies aspired to IPOs, VC investments or being acquired - is that vendors love to talk about their customers - and what they're doing - even if it's just the same old "new SSD was better / faster/ cheaper than my old vintage RAID" story.

Several years ago Texas Memory Systems used to circumvent some of their customer reticence by hinting - if you use any of the big internet shopping sites you were probably using their SSDs.

This narrative trend was continued to another level later by Fusion-io who used to say - if you use the internet at all - then some of your data may be passing through their ioDrives.

It would be relatively easy to construct a list of the top internet sites and then attach brand names of the SSDs they had been known (or suspected) of using in their server infrastructure. But why bother? A randomly generated list - picked from the Top SSD Companies Lists - might be nearly as accurate. It's impossible to do anything worthwhile efficiently with vast amounts of data in a timely fashion without using SSDs.

Violin files for IPO

Editor:- August 28, 2013 - Violin Memory recently announced it has filed a registration statement on Form S-1 with the SEC relating to the proposed IPO of its common stock. The number of shares to be sold and the price range for the proposed offering have not yet been determined. Violin Memory plans to list its common stock on the NYSE under the ticker symbol "VMEM."

Editor's comments:- How much is Violin worth?

On the plus side - Brand strength and IP. It's been consistently either #2 or #3 of the Top SSD Companies List based on search volume for the past 2 years. (That's based on all SSD companies - not just makers of fast and high availability rackmount SSDs. In those specialized categories - it's the #1 company.) On the IP side - Violin is just one of handful of companies in the SSD market which has its own market proven big SSD controller architecture - which gives many competitive efficiency advantages.

Most similar to? - Comparisons are hard to make because the market has moved on in the past year - and I don't know how much IBM paid for Texas Memory Systems (based on market conditions before the deal was announced in October 2012).

At that time I would have said TMS was worth more than Violin - because TMS also had a proven PCIe SSD product line which used the same controller IP as its rackmounts. Since then, however, Violin has improved its software IP with the acquisition of GridIron Systems - and nudged by investor Toshiba - Violin has also grudgingly entered the PCIe SSD market too. So in technology terms the Violin of August 2013 comes out slightly ahead in the SSD IP assets count compared to the year-ago TMS.

If SSD systems companies are worth more or less today than they were a year ago - that suggests Violin today may be worth more than the market adjusted relative price IBM paid for TMS. That gives you one way - but not the only way - to estimate a low end sanity check valuation figure.

Biggest weakness for Violin? - It has no adaptive R/W flash IP. That means it can't compete head to head on price with the most aggressive vendors in the fast-enough SSD rackmount segment - in particular with companies like Skyera.

On the other hand - maybe Violin doesn't have to.

It already has leading assets in 3 of the main enterprise SSD silos - fast SSDs, HA SSDs and SSD ASAPs auto-tiering/caching. Those markets are big enough. Maybe one business strategy for Violin post IPO might be to stay out of the low end iSCSI SSD market entirely for a few years.

AutoCache version 2

Editor:- August 26, 2013 - Proximal Data today announced the release of version 2.0 of AutoCache (SSD ASAP software). Pricing starts at $999 per host for flash caches less than 500GB.

The company has been demonstrating the new version working with PCIe SSDs from Micron at VMworld.

SanDisk completes SMART acquisition

now has the assets to enable ambitions in enterprise SSD

Editor:- August 22, 2013 - SanDisk today announced it has completed its acquisition of SMART Storage Systems whose president John Scaramuzzo will now assume the new role of senior VP enterprise storage solutions at SanDisk - reporting to Sanjay Mehrotra, president and CEO.

Editor's comments:- I've been reporting on SanDisk's metamorphosis on the way to becoming a serious enterprise SSD company since long before they acquired Pliant Technology (an SAS SSD maker) in May 2011.

Lessons were learned from that - and a transformation seemed to take place in SanDisk's thinking triggered by their acquisition of FlashSoft in February 2012 - which enabled SanDisk to get much better clarity on what was really happening in a wide range of enterprise SSD users' sites - as a result of feedback coming from customers using its SSD software.

The 4 key assets which SMART brings to SanDisk in the enterprise SSD context are:-
  • enterprise grade (world class) adaptive R/W flash SSD technology.

    SMART has already demonstrated - in launched products - that this technology is scalable across a wide span of cost, power consumption and IOPS use cases.

    And at the fab level adaptive R/W IP increases SSD efficiency (usable SSDs per wafer).
  • an attractive (tier 1 validated) SAS SSD and enterprise SATA SSD product mix which has already displaced competitors in many leading server and storage oem design wins.
  • an embryonic new type of SSD - memory channel storage - which aims at the market space of fast PCIe SSDs - and which - if successful - could change the future mix of motherboard memory used in servers.
  • a team of technical, sales and marketing people with a long track record of successful product innovations in the mission critical flash SSD market.
Unlike the other Top 10 SSD company acquisition which is currently in the pipeline (Stec by WD which may need a lot of reworking to make it fly) - the SMART product lines within SanDisk have already been expanding their reach of new customer destinations.

If you look at what LSI did with SandForce - I think that provides a better idea of the future scale and speed of ramp up which you can expect to see with the new enterprise SSD business in SanDisk.

what are enterprise SSD users thinking? - especially if it's wrong

Editor:- August 22, 2013 - In a confusing market like enterprise SSDs where the accepted wisdom of what makes good technology keeps changing - and the interpretation of market trends depends on who's looking at the same data - what can vendors do to try and make sure they're aiming in the right direction and doing things which will sell?

Getting closer to their customers is one way - and most leading vendors do that already. But it's not infallible.

How about customers they're not reaching yet? What are they thinking? - Especially if it's wrong or based on perceptions which are out of date. Vendors need to understand how users tick so they can adapt their own product plans and the way they talk about them.

About a year ago I was contacted by Frank Berry, CEO of IT Brand Pulse who told me about the new way they were doing market research into the SSD market:- surveying enterprise users and asking them what they think about brands, technology decisions and other key issues.

That sounded like a good idea - but in recent years I've heard from a great many companies which said they wanted to do more reports in the SSD market - and although I've been happy to mention some of them on this and similar news pages I've reserved my short list of special SSD market research companies for those who - in my opinion - have invested the resources to create valuable SSD insights over a period of many years. I thought it might be years before I added IT Brand Pulse to that list (if ever).

Turns out I was wrong.

And while I was aware that Frank Berry and his team have been doing more work in the enterprise SSD area in the past year - it was only when I got a summary of their recent presentation at the Flash Memory Summit - SSD Adoption Trends (pdf) in my email this morning - that I realized the scale of what they have already achieved.

There's some really useful information here about SSD user decision points and current usage preferences as well as brand data and market perceptions. (You have to skip through the early parts of the document to get to the interesting bits.)

Some of the feedback from these survey participants...
  • SSDs will be approximately 3x the current percentage of their organization's combined SSD and HDD disk capacity within 2 years
  • Virtualized servers are the biggest driver for SSD adoption (above database servers)
  • Nearly as many organizations have already deployed SSDs in some of their servers as those who have not deployed any type of SSDs at all. (A list of participating surveyed organizations is included in the paper.)
This free version of the paper includes unscaled graphs - and charts without numbers. But it makes a good read as it is. For those who need the raw data and numbers - the cost is $1,500. the article (pdf)

Editor's comments:- IT Brand Pulse has demonstrated its commitment and ability to enhance our understanding of the enterprise SSD market. So I've fast tracked them by several years into my recommended SSD analysts list.

DRAM technology won't advance soon - says Micron

Editor:- August 20, 2013 - In recent years the SSD market has become nearly 100% flash (and nv memory) focused - with little or no mention of DRAM based SSDs. The reason is that nearly every company whose product line used to be mainstream RAM SSD - has pulled out of that market or discontinued enhancements to those products. Flash SSDs are more economic and easier to sell.

It doesn't mean to say that the role of DRAM in SSD systems has entirely disappeared. It still appears as a cache or tier in many flash SSD arrays and the existence of some small percentage of DRAM is assumed in SSD caching software and also in (flash based) memory channel SSDs.

Micron sent out a useful signal of where its own DRAM roadmap is going in an article yesterday in EETimes - which reports an interview with Micron's president Mark Adams who said - "There will be no new greenfield DRAM fabs for the foreseeable future. We are hitting something of a lithography wall in DRAM where shrinks are getting tougher and gains are not as attractive, so people are not as financially motivated to invest in new fabs. Also we see planar DRAM advances will end in the next 3 to 5 years, so you probably cannot get ROI in a new planar fab." the article

SolidFire - as an anti-jitter service in the cloud

Editor:- August 19, 2013 - SolidFire provides the underlying rackmount SSD support for a new SSD empowered cloud product Platform as a Service (PaaS) being offered by IT Solutions Now which I learned about in a blog by Sorab Ghaswalla on Software Tools Journal.

Editor's comments:- cloud companies - like the stars in the sky - are nearly numberless - however if you want to see a partial list of who they are - SolidFire's news page is cluttered with the names of cloud companies - and reads almost like a set of audited customer accounts than a technology news forum - which can be off-putting - if like me - you're looking for SSD content - rather than SSD investment fodder.

But although I couldn't find any mention of this particular story on my brief visit to their website this time around - I was reminded about an interesting observation which SolidFire had written about earlier (in February 2013) regarding the performance and QoS impacts that "Noisy Neighbors" can create in a shared storage infrastructure.

Their leading theme is cloud service providers - but this issue is also critical to almost any realistic deployments in an enterprise context - and is the implicit reason that many architects have preferred to isolate critical apps servers in the past - even within their own datacenters - rather than risk mixing them all up in pools.
noisy neighbor graphic by SolidFire
In a cartoon (they call it an "infographic") - Noisy Neighbors in the Cloud (pdf) - SolidFire captures the essence of this performance randomizing problem - whose solution (you guessed it) is to use more (of their) SSDs.

what did they talk about about at the Flash Memory Summit?

Editor:- August 19, 2013 - PDFs from the recent Flash Memory Summit are now available for free download from the event's web site - click here for an overview.

Among other things startup NVMdurance's endurance stretching characterization software was judged to be one of the most innovative flash memory technologies seen at the Flash Memory Summit.

OCZ obtains $13 million additional funding

Editor:- August 13, 2013 - OCZ today announced it has raised approximately $13 million in a private placement of debentures and warrants. The company also said it has retained Deutsche Bank Securities Inc. as financial advisor to assist the board of directors in evaluating various strategic alternatives.

Samsung offers 1st generation 3D nand flash SSDs for enterprise

Editor:- August 13, 2013 - Samsung today announced it has started production of 2.5" SATA SSDs aimed at the enterprise market - which use the company's new 128Gb 3D Vertical NAND flash memories.

Samsung says its 3D flash is intrinsically more reliable, faster and uses less power than traditional 2D flash at the same (10nm class) line geometries.

Editor's comments:- As SSDs - and compared spec by spec to any other SSDs - the new V-NAND SSDs aren't remarkable - 960GB capacity and 35K write endurance - which is what the market (in this case - cloud storage array makers want).

But Samsung's new V-NAND SSDs are simply the first step in the journey towards characterizing this new technology and to achieve customer acceptance.

Samsung says its 3D technology could deliver upto 24 cell layers vertically, using special etching technology that connects the layers electronically by punching holes from the highest layer to the bottom.

When that happens - each wafer will be able to deliver an order of magnitude more storage capacity from the same number of wafer starts - using the same line resolution as traditional (planar) flash cells. (If you think about the difference it made when the market went from SLC to MLC and then again to TLC - the eventual market impact will be bigger than all those combined.) But getting the chips and production equipment proven and economic for double digit 3D cells will take years from where we are now.

Adding each vertical layer takes additional processing time. In some ways it's like adding more layers to your pizza - except that - the successive layers of topping have to match up very precisely. (Around 2,000x more precisely than the state of the art in metal additive technology - to give you an idea of the difficulty and the elapsed time element.)

Skyera says 1 petabyte SSD will go into 2U

Editor:- August 13, 2013 - Skyera today announced that. among other things, it will introduce PCIe connectivity (to the existing FC and iSCSI) as well as replication in the next version of its rackmount SSDs - the skyEagle - which will ship in the first half of 2014 - offering 500TB uncompressed (2.5TB deduped and compressed) in a 1U form factor at a record breaking list price expected to be under $2,000 per uncompressed terabyte.

Editor's comments:- not a lot of people remember this - but 6 years ago- in August 2007 - when Violin emerged from stealth mode with one of the fastest rackmount SSDs of that era - Violin's 1010 was also the first well known enterprise SSD which offered PCIe as the primary connection option. (This was the month before Fusion-io launched its first ioDrive and began its multi-year mission to re-educate and change the way that the enterprise market viewed SSDs BTW.)

But in 2007 the enterprise market was still grappling with the idea of rackmount SSDs - and for those buying - their connection of choice was FC SAN. That meant Violin's initial product made a market impression - but the company had to wait for its later systems - redesigned with FC and flash - to get the sales which would secure its future as the new leader in the rackmount SSD market (replacing Texas Memory Systems). Violin's early experience with PCIe being the wrong interface for its rackmount market left scars in the company's psyche. So it wasn't till nearly 6 years after that Violin entered the (now) safely conventional market for module and card based PCIe SSDs.

Today in the market of August 2013 - PCIe has evolved into a very different technology and market proposition for enterprise SSDs.
  • As a technology (it can be used as a fabric to interconnect fast racks - a bit like InfiniBand in some respects - except that the ecosystem of compatible SSDs is much richer and price competitive).
So I view the 96 lanes of PCIe connectivity - in Skyera's forthcoming skyEagle - as a way of reaching out to an entirely new market. This PCIe option provides a simple and cheap foundation for clustering boxes in high availability configurations.

And how about the idea of 1/2 petabyte SSD in a 1U rack next year?

Back in early 2010 - when I published an article designed to show what one of the missing products in the future enterprise SSD market would look like - and its consequences for hard drives - this way to the petabyte SSD - I guessed we'd see a 2U petabyte SSD in 2016.

Skyera is going to beat that timescale by 2 years. Which incidentally means that all the other predicted dates about the consequences for hard drives in an enterprise SSD world - are also 1 or 2 years earlier than anyone previously imagined too.

new ORG maintains magnetic storage spin

Editor:- August 13, 2013 - Today a new storage org was launched to conserve and nurture the interests of rotating magnetic hard drives and hybrids. Founder members of the Storage Products Association are HGST, WD, Seagate and Toshiba.

Among other things - the SPA's faqs page says "the SPA will seek to clarify how hard drive technology, solid-state technology and variations of these technologies may be combined to effectively meet the needs of a growing storage requirement."

Tegile says its sales exceed its VC funding

Editor:- August 13, 2013 - Tegile Systems (which operates in the SSD ASAP market) today announced the closing of its $35 million Round C funding led by late-stage venture firm Meritech Capital Partners with additional investment by original stakeholder August Capital and strategic partners WD and SanDisk.

Editor's comments:- Tegile says that unlike some other VC funded companies in this market space which have lived mostly on investments Tegile has generated more customer revenue than it has taken in outside financing.

LSI says it pays to get a 2nd opinion from LDPC

Editor:- August 13, 2013 - Within the context of SSD controllers and the various industry options related to managing bad blocks and adaptive DSP ECC - LSI explained why it thinks that reserving the use of LDPC to deal mostly with read error retries (and also later in the operating life of flash cells) can be a pragmatic design choice - in a presentation - the Nibbles and Bits of SSD Data Integrity (pdf) - today at the Flash Memory Summit.

And instead of applying different strengths of ECC for fixed physical block sizes - the company says another approach is to have variable sized virtual blocks - which effectively mean that better cells carry lower ECC overhead.

Enmotus demos hybrid arrays

Editor:- August 13, 2013 - Enmotus announced that it is demonstrating its FuzeDrive (hybrid SSD ASAP) solutions (with Toshiba SSDs inside) at the Flash Memory Summit.

"While helping accelerate early adoption of SSDs, today's caching solutions don't always provide the results users expect. FuzeDrive avoids using traditional caching techniques, and instead borrows its concepts from intelligent real time virtualization, data movement and storage pooling techniques typically found in larger 'big iron' enterprise systems," said Andy Mills, CEO and Co-founder of Enmotus.

Proton Digital launches new controller platform

Editor:- August 12, 2013 - Proton Digital Systems today announced details of its new LDPC based FlashPro (a large architecture, adaptive DSP, controller ) platform which will be demonstrated this week at the Flash Memory Summit.

Proton says its error recovery technology enables reliable deployment of next generation 1y-nm/1z-nm MLC, TLC and 3D Flash memory from all major NAND Flash manufacturers. FlashPro also features a micro-programmable sequencer that supports Toggle and ONFi interfaces and addresses all flash commands, including customer-specific commands.

FlashPro has upto 8 flash channels each supporting 533MBps and up to 32 Chip Enables per channel. Each media manager can support data transfer rates from 50MBps up to 4.27GBps and multiple instantiations can be integrated to achieve the desired capacity and performance.

Silicon Motion samples fast low power SATA 3 SSD controller

Editor:- August 12, 2013 - Silicon Motion today announced it has begun sampling a low power consumption, fast SATA 3 regular RAM cache SSD controller which supports MLC, TLC and SLC NAND flash from all the major NAND suppliers.

The SM2246EN supports 4 channels of NAND flash devices with up to 8 CEs per channel and can enable sequential reads upto 540MB/s and writes upto 410MB/s. Random IOPS performance is upto 80,000 read IOPS and 75,000 write IOPS. Average power consumption is 60mW. Security features include AES 128/256, TCG and Opal full-drive encryption compliance.

Editor's comments:- in a paper this week at the Flash Memory Summit - the Efficient LDPC DSP System for SSD (pdf) - Jeff Yang Principle Engineer, Silicon Motion discussed how its adaptive LPDC DSP techniques which supports variable parity lengths provides 3x better data integrity than traditional BCH.


Editor:- August 8, 2013 - SMART Storage Systems today announced it has begun sampling the first memory channel SSDs compatible with the interface and reference architecture created by Diablo Technologies.

SMART's first generation enterprise ULLtraDIMM SSD (ULL = ultra-low latency) can be deployed via any existing DIMM slot and provides 200GB or 400GB of enterprise class flash SSD memory with upto 1GB/s and 760MB/s of sustained read/write performance, with 5 microseconds write latency. Throughput, IOPS and memory capacity all scale with the number of ULLtraDIMM deployed in each server.

ultra low latency memory channel SSD

Editor's comments:- With the current design -only one DIMM slot in each server has to be reserved for conventional DRAM. Apart from that constraint any DIMM slot can be used for either flash or DRAM as deemed necessary for the application.

For more about the potential of this technology, the thinking behind it and the competitive landscape relative to PCIe SSDs etc see my earlier articles on the Memory Channel SSDs page.

Stec's revenue shrinks again

Editor:- August 7, 2013 - Stec today announced that its evenue for the quarter ending June 30 declined 42% year on year to $23.5 million.

Editor's comments:- I enumerated Stec's 3 main defficiencies in sales and marketing in my comments November 8, 2011.

An anti-sales and anti-marketing culture was embedded in the company's management DNA as I was able to learn from my own contacts with the company over many years.

Throughout the long history of the SSD market Stec never advertised SSDs here on

Looking ahead if WD proceeds with its announced plan to acquire Stec - it will be getting some SSD design files and some patents - but not a quick turnaround platform for a viable enterprise SSD business.

Anticipating this kind of conclusion in August 2011 - I said on these SSD pages - "STEC is now cheap to buy - but would be very expensive to own..."

Virtium offers offer faster range of extended temperature SSDs

Editor:- August 7, 2013 - Virtium today introduced a new line of faster 1.8" and 2.5" rugged SATA SSDs (80, 160 and 300GB capacities) for applications in in-flight entertainment, PoS terminals, gaming equipment and mobile monitoring systems.

"Don't use Self-Encrypting SSDs (if you think you might need a future data recovery)..."
That's the "advice" in a blog SSDs: Flash Technology with Risks and Side-Effects (August 2013) - by Kroll Ontrack - which goes on to say -

"This type of encryption is very secure, but ensures total data loss in the event of a failure. With SEDs, the encryption keys are only known to the hardware manufacturers and will not be released. What this means is in the event of a failure, the data is no longer accessible to professional data recovery companies".
