Who's who in SSD? - Nimbus
by Zsolt Kerekes, editor - February 2013

Nimbus Data Systems is 1 of more than 100 companies in the rackmount SSDs market.

when did they enter the SSD market?

Nimbus has been shipping SSDs in its racks since 2008 - initially as accelerator options for its HDD arrays - and since January 2009 as pure solid state storage. The company's internal hardware architecture is what I call "open" - in that it is based on RAID like arrays of 2.5" SAS SSDs which the company designs itself and which use eMLC. But Nimbus doesn't sell SAS SSDs to other SSD array companies.

The company is also 1 of many companies in these directories / market segments:- rackmount SSDs, iSCSI SSDs, FC SANs, Infiniband SSDs and HA SSDs.

Top SSD Company?

Nimbus made its debut in's list of the top 20 SSD companies - in the 3rd quarter of 2011.

In the most recent time-frame - 2nd quarter of 2013 - Nimbus was ranked #10 (it has been higher).

In January 2013 - the company announced it had been shipping at the rate of over 1 petabyte of SSD storage / month. (That was back in the days when a petabyte of SSD was considered to be a significant quantity. Looking ahead to 2014 that's the SSD capacity you'll find in just 2U of Skyera rackspace.)

enterprise Silos?

Nimbus has never appeared in the fastest SSDs list. In my enterprise SSD silo categories I think Nimbus is a good fit in the fast and the high end of fast-enough rackmount SSD roles.

architecture and IP strengths?

SSD software is a substantive differentiating IP asset of the company. The HALO storage OS is integrated in all its SSD racks.

The strong factors in Nimbus's SSD architecture are its software - which in my view benefits from the company founder's unique experience in developing unified SAN architectural concepts for more than a decade. And by designing its own SSDs - Nimbus is able to tweak system architectural features - such as performance (non blocking SAS backplane), manageability (better integration with SSD controller data), high availability (failover routing) and cost. The flash modules are about 80% of the hardware.

Nimbus - selected milestones and comments from SSD Market History

In April 2008 - Nimbus announced an SSD accelerator option in its Breeze H-series 10GbE IP Storage (SSD ASAP). A system with 34TB of storage, and 64GB of mirrored SSD costs about $120,000.

Nimbus carries on the torch of a network storage operating system - which under the name "Cloudbreak" - was first developed by Nimbus's founder at TrueSAN Networks .

That's the kind of groundwork thinking you need to make an SSD accelerated storage system work economically as part of a hybrid HDD-SSD array - while avoiding high manual setup, tuning and configuration costs.

In January 2009 - Nimbus launched its DH200 - a 4 port 10GbE NAS - which supports upto 10TB of flash SSD storage. See also:- rackmount SSDs.

In April 2010 - Nimbus Data Systems launched its S-class storage system - a 2U 10GbE rackmount SSD with 24 hot swappable internal 6Gbps SAS flash SSD blades in an 80W power footprint offering 5TB protected capacity for $39,995. 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. my discussion with Nimbus's CEO

InJuly 2010 - Nimbus Data Systems- announced higher density in its 10 GbE rackmount SSD systems - 10TB (enterprise MLC) in 2U - implemented as 24 x 400GB hot-swappable SAS flash blades. The company also announced improved connectivity - upto 120Gbps - from its internal 12 port FlexConnect 'virtual switch' which makes all storage available to all ports without the need to create and assign volumes to specific ports. Pricing for a 10TB system with FlexConnect is just under $110k.

In February 2011 - Nimbus Data Systems announced that it achieved profitability in its fiscal year ending December 31, 2010.

"Today's announcement of achieving profitability marks Nimbus' maturity from an innovative startup to an established storage player intent on achieving rapid market expansion, unmatched innovation, and leadership in the emerging sustainable storage and flash memory storage market," stated Thomas Isakovich, CEO and founder of Nimbus. "Our commitment to customer satisfaction and responsible growth reflects in this important company milestone."

In August 2011 - Nimbus Data Systems announced that eBay has deployed more than 100 terabytes of Nimbus S-Class flash memory to power its VMware virtual server infrastructure. The Nimbus solution delivered near line-rate 10 Gbps iSCSI performance to the VMware hosts while consuming 78% less energy and 50% less rackspace than conventional disk-based solutions.

Nimbus also announced added InfiniBand and FC SAN support to its pre-existing interface options.

In October 2011 - Nimbus entered's quarterly list of the top 20 SSD companies for the first time - coming in at #16 for Q3 2011.

In January 2012 - Nimbus announced its entry into the high availability enterprise SSD market with the uveiling of the company's - E-Class systems - which are 2U rackmount SSDs with 10TB eMLC per U of usable capacity and no single point of failure. Interface support includes unified 10GbE, FC, and Infiniband. Pricing starts at $150K approx for a 10TB dual configuration system.

In March 2013 - Nimbus Data Systems announced new software APIs which support its proprietary HALO OS based family of rackmount SSDs - and report on hundreds of real-time and historical metrics such as:- flash endurance, capacity utilization, latency, power consumption, deduplication rates, and overall system health. Another new feature is health monitoring apps which run on Android / Apple phones and tablets.

who are Nimbus's hottest competitors? - are you sure about that...
Editor:- August 23, 2012 - SSD companies often misidentify (in my view) who their most serious sustainable competitors really are - as predicted by which enterprise SSD apps silos they satisfy best.

I was discussing this recently with Thomas Isakovich, CEO of Nimbus Data Systems and Scott Kline , Director of Corporate Communications as they were getting ready to launch a new fast SSD rackmount system (which they earlier this week.)

What I was most interested in - was the companies they had named as key competitors.

For the record - Nimbus's list included:- Violin Memory, Texas Memory Systems, Pure Storage and SolidFire. And the idea behind the document was to suggest that the new system from Nimbus (called the Gemini ) is at least as good or better than the competition - based on what was being compared.

It was clear to me that a lot of effort had gone into preparing their briefing document - showing things like comparative capacity per U, price per TB, IOPS, latency and that sort of thing. And I told them I enjoy reading these things - because they are the closest I get to reading SSD articles (or joined up writing about the SSD market) which someone else has written.

I said - "There are 2 companies in there which I wouldn't have had on the list at all - and at least one other that I would have added instead.

Now I knew I had their attention. I always try to divert from any preordained script about the SSD market - because that's what makes these conversations interesting.

"And how did you decide which competitors to put on the list?" - I asked.

"We put companies on this list based on those mentioned as competitors by customers" they said.

"Well" I said "that explains it. Most end-users often aren't clear enough in their own undertanding of what they need - and many SSD vendors aren't focused enough yet to know which business they should go for and which they shouldn't waste time on. But just because you butt up against a bunch of companies doesn't mean to say they are your most serious long term competitors."

"Who would you take out of the list?" Tom asked "and why?"

I said Pure Storage - because they aren't in the same performance class as you (Pure is fast-enough - whereas Nimbus is fast). And I'd have left SolidFire out of the comparison table too.

Another - even better reason not to have them in your comparison list - I said - is that Nimbus has from time to time appeared in the Top SSD companies list - whereas Pure Storage and SolidFire haven't. It's less important to worry about competitors with much lower ratings and concentrate on what you can do about competitors who are already scoring better than you in the minds of the market.

Obviously Nimbus wasn't going to argue with me about that angle.

"OK" Tom said - "who would you put in the list instead?"

"Fusion-io" - I said. "Because their new ION software is a significant product capability which intersects with the set of paramaters you've shown in your competitive rankings. The cost and performance of FIO ION based systems will be an important factor in the fast rackmount SSD market."

My thinking about this is that while it's unlikely that many end users would realistically look at an SSD rack from Nimbus and Fusion-io based technology as viable suppliers for exactly the same application slot - there would be a small number of high volume end users who would be perfectly happy with the ION based solution and would wrap their own cloud-like fault tolerant wrappers around it - if they thought it would give them a significant cost saving compared to the built in HA/FT in the Nimbus product.

And because Fusion-io may already be in use in servers within a customer site - that meant that a starting point for competitive comparisons in rack based SSDs would often be FIO based - even if it wasn't an exact functional fit.

Nimbus said they have supplied their rack SSDs into customers who were using Fusion-io cards in servers.

I said I wasn't surprised because there are some apps where that would be the best thing for the customer to do. (I'll be returning to the subject of boundary conditions in the enterprise SSD market in my September blog.)

Another thing I asked Nimbus was - do they support adaptive DSP?

Nimbus said no.

I said - that's another thing which is going to impact the cost per TB in enterprise SSD racks - so I didn't think that the cost leadership they were showing in their tables would last for long. (That was before the recent launch by Skyera BTW - which is another company to add to the compete-with list.)

OK - so apart from chatting about the SSD market - what did I learn about Nimbus's new SSD?

As I said to Tom and Scott - what's interesting is that if you assemble a list of leading competitively priced fast SSD racks - then you can get very similar performance, pricing and capacity density from systems which have very different internal architectures.
  • proprietary:- TMS, Violin
  • open (array of PCIe SSDs) - Fusion-io
  • open (array of SAS SSDs) - Nimbus
Customers with different risk profiles (roadmap symmetry) and prefences about the granularity of how they replace SSDs (is it the module or rack level? - it's less risky pulling out 2.5" SSDs than conventional PCIe SSD cards for example) will lean towards one type of supplier rather than another.

For the same reason - most enterprise SSD users will wait several quarters to see how reliable Skyera's new systems are in somebody else's environment rather than risk being early adopters - even Skyera does have the lowest price in the industry.

3 factors in the Nimbus racks which I should mention here - and which I haven't written about before are:-
  • internally the array has point to point connections to every SAS drive. That's a factor in throughput performance and latency.
  • the Nimbus product allows non-disruptive software updates.
  • Nimbus use high level software in their OS as part of the endurance management. Overall their rack supports 50x full capacity writes each day for 5 years. (That's a good figure which compares with adaptive DSP - although Nimbus is doing this a different way using RAM cache in each of their flash SSDs.)

another conversation with Nimbus - PCIe SSDs and VCs
Editor:- February 2, 2012 - I had an interesting discussion yesterday with Thomas Isakovich, CEO and founder of Nimbus which recently launched its first high availability SAN SSDs.

To be sure - HA enterprise SSDs is an "up-for-grabs" SSD growth segment so that is interesting in itself - but I told Nimbus's Marcomms Director, Scott Kline - in advance of the call that I would be much more interested in having a general update about how Nimbus sees itself in the SSD market - than simply having a CEO voice-over of their new SSD rack's bullet points - particularly as Nimbus said it was profitable (unlike some other well known enterprise SSD companies).

a long view

In the minutes leading up to my call with Tom Isakovich yesterday I looked up his email address (which I always do just in case the phone fails to connect) and I reread some earlier exchanges we had going all the way back to when he was in his previous company in 1999.

It got me thinking - this is someone who takes a long term view of where enterprise storage is going. It occurred to me that if I were to publish some of Tom's views and predictions from more than a decade ago - they would still stand the test of time as sound bites today.

a profitable enterprise SSD company

Tom told me Nimbus is profitable and debt free. As a private company they don't disclose revenue. But revenue last year was 5x the year before.

VCs IPOs and acquisitions

Tom said because they don't have VCs involved they have more freedom to pursue product development and business development strategies. Currently that would be via organic growth. So it looks to me that unlike VC backed loss making SSD competitors - they don't need to steer in the IPO or wannabe acquired lane.

SAS SSD arrays latency vs PCIe SSDs

I aked if they had any plans to support PCIe SSDs (or 2.5" PCIe SSDs) with their virtualization software - because I guessed they could do it - if they saw a market opportunity for it.

Tom said - no. Nimbus is sticking with network storage boxes based around removable SAS SSDs. He could see no advantages for them to start integrating PCIe SSDs.

When I asked about latency - Tom said that in one customer evaluation - a Nimbus system with an Infiniband connection delivered better latency than a PCIe SSD competitor with an IB router. So in the rackmount SAN SSD space where Nimbus was focused - PCIe SSDs didn't offer anything for him that he couldn't do with SAS.

Inside server racks - he agreed - users would use a lot of PCIe SSDs - just as HDD SANs didn't replace the need for server DAS.

where is the core of Nimbus's SSD IP?

As I expected - Tom said - it's mostly in their software - which can manage half a petabyte of SSD in a single unified file system.

I knew from earlier conversations that Nimbus design their own SAS SSD modules - but I wasn't sure - apart from cost advantages and lowering the risk of firmware shocks - just how important their hardware IP was. Tom said that their earlier non-blocking mid plane technology was a factor in performance - but their new seamless HA failover architecture couldn't be done so well with commercial off the shelf (COTS) SSDs.

watts and Petabyte SSDs

Tom said that big data SSD enterprise customers (like eBay - which uses Nimbus SSDs) look beyond price/performance to assess running costs and density - and he said he thought that Nimbus's SSDs (TB /U and W/TB) are leading the market in those respects.

I said that competitors like Texas Memory Systems and Violin - would be sure to disagree on many of the "best" claims in their press release documents but Tom said that for many users Nimbus's HALO software would be the deciding factor.

I ended by saying that in 2012 - enterprise SSD makers with reliable market proven products - would see customer demand growing on a scale they had never seen before - and as my stats tell me that many of you readers are interested in learning more about Nimbus - I'll be updating my profile for them more often.

Nimbus awarded patent for non blocking technology
Editor:- December 21, 2016 - Nimbus Data Systems today announced it has been granted a patent - 9,268,501 - for the non-blocking data fabric architecture which is used in its petabyte scale SSD racks.

"Conventional HDD-centric architectures employed by the majority of all-flash array vendors trap flash performance behind legacy shared bus and scale-up designs," said Thomas Isakovich, CEO and Founder. "Now patented, Nimbus Data's Parallel Memory Architecture overcomes the limitations of generic off-the-shelf servers, capturing the full performance potential of all-flash technology."

Editor's comments:- Nimbus's patent relates to a non blocking SAS-aware fabric technology.

Other notable SSD box makers which have gone on the record to talk about their non blocking matrix switch arrangements to reduce latency and improved throughput include Texas Memory Systems (now IBM's flashsystem) and Violin Memory (VXM).
Nimbus re-emerges from stealth with 1PB / U raw HA SSD
Editor:- August 9, 2016 - Nimbus Data Systems has emerged from its self imposed exit into marcomms stealth mode with the announcement of a new range of Ethernet/FC/Infiniband attached rackmount SSDs based on its new ExaFlash OS with GA in Q4 2016.

Entry level products start in a 2U box with 50TB raw capacity for under $50K and for larger configurations Nimbus says its ExaFlash offers an effective price point as low as $0.19 per effective gigabyte (including all software and hardware).

Higher density boxes in this product line - D-series models - will have 4.5 PB raw capacity in 4U (12 PB effective).

Re the architecture - I haven't seen details - Nimbus says there is no data network between the storage arrays themselves, guaranteeing that performance truly scales in lock-step with capacity and with consistent latency.

4 petabytes raw 12 effective in 4U

video above shows the 4PB raw ExaFlash at FMS

Editor's comments:- if there are to be sustainable roles in the future consolidated enterprise SSD systems market for AFA vendors which previously sold arrays of SAS/SATA SSDs - and who don't own their own semiconductor fabs - the only viable ways to establish such platform brand identities are with SSD software and architecture.

There's a huge gap between the technological aspiration which Nimbus talks about and the weakness of its past marketing and the kind of funding which we've seen competitors in this market burn through in the past with mixed results.

In the next few quarters I hope we'll hear more from Nimbus about its business development plans and customer adoption.

We're now nearing a pivotal point in the enterprise SSD market where the long held assumptions I helped to encourage (especially how many leading systems vendors there will be in the market at the same time) are about to change dramatically.

Pure Storage's funding coffers fattened up to nearly $0.5 billion
Editor:- April 23, 2014 - Pure Storage today announced it had raised another $225 million in funding - bringing the total in all rounds to $470 million.

Editor's comments:- One of Pure Storage's many competitors - Nimbus - whose CEO has taken a different approach to funding (so far) - this week published an unflattering side by side features comparison between the 2 company's flagship rackmount SSDs.
Among the SSD vendors listed in DCIG's report - the happiest will be Nimbus (who have been crowing today about being #1).
Editor:- March 31, 2014 - If you're interested in rackmount SSDs then DCIG has published the DCIG 2014-15 Flash Memory Storage Array Buyer's Guide (free sign-up page) - which provides detailed comments on the strengths and weaknesses of rackmount SSD systems from 20 different vendors - which are currently available in the market today (includes list prices).

DCIG have created their own multi-dimensional scoring system in which they look at component features such as density (TB/U), software compatibility (for example ease of integration with VMware), and management functions (dedupe, tiering, snapshots etc). DCIG has ranked these systems overall - and compared many of them to others in the same price band. Another useful feature of the report is a background story about the design heritage or market history of each product.

Editor's comments:- I've read the report and think it's a good read with respect to the raw data and detailed observations about many of the systems listed.

As to the product rankings?

I think whether you agree or not - depends on whether you would assign the same weights to each constituent in the confidential matrix of factors which DCIG have devised.

For some users it will reflect your own priorities - for others - the scoring outcome would be entirely different.

Among the SSD vendors listed in the report - the happiest will be Nimbus (who have been crowing today about being #1) - and happy too should be HP (which is #2).

Some vendors - whose products are best in class in a particular dimension - don't score highly in the main list because they lose out on the "sum of all things which DCIG think you might need" - which is an application dependent judgement - rather than being a universal "goodness" attribute.

The only company which is conspicuously absent from DCIG's list (at any rank) is Fusion-io. Does DCIG know something we don't? That's very odd. Related articles:-
coming soon - an incrementally denser rackmount SSD from Nimbus
Editor:- February 25, 2014 - What does a petabyte of pure flash enterprise SSD look like?

It depends on who makes it, the relative speed category of the storage itself and the user's own preferences for high availability schemes and associated software.

At the densest (best) level - a petabyte of enterprise SSD can occupy as little as 2U rack space (skyEagle from Skyera).

The upper limit in size depends a lot on the internal architecture and memory type - but typically occupies 10x to 20x more physical space than the example I've given above.

On that theme - Nimbus Data today announced that in April it will sample the next generation of its own fast software rich featured SSD systems - the Gemini X - which will provide an incremental 2x capacity density improvement over the company's previous offering.

news image - click to enlarge

The Gemini X implements 960TB (raw) unified SSD storage with 100 microseconds latency (at under 6W / TB) in 24U of rackspace (40GB/s internal bandwidth) with external connection via 10 dual ports which can be 16Gb FC, 40Gb Ethernet or 56Gb Infiniband.

Like most leading vendors - Nimbus likes to think that its product are better than some other named competitors. But all such comparisons are very selective.

Nimbus IPO date? - this may be the leading indicator to watch out for
Editor:- October 1, 2013 - I was talking recently to Tom Isakovich, CEO and founder of Nimbus Data Systems...

I asked Tom if he thought the air of uncertainty hanging around competitors in the SSD systems market was affecting the competitive situation for his own company. In particular I raised the subject of Whiptail's announced acquisition by Cisco (would the products still be available? or would some get dropped - like when IBM acquired TMS). The ticker ride for VMEM was still a week into the future when we spoke but anyone who had read Violin's IPO disclosures could see their predicament.

He said Nimbus rarely encounters those other SSD companies as competitors in customer sites - so he didn't expect to see any short term impact either way. Tom views his real competitors as being the big traditional storage companies and so when Nimbus gets an order from a customer who has been using big name storage - he regards that as being far more significant than beating another SSD systems "startup" - because Nimbus is competing against prevailing customer inertia.

He also said that apart from any technical differences between Nimbus and Violin (he thinks Nimbus's software stack is better) - the other difference is that Violin hasn't been profitable and its revenue growth rate has been unreliable.

In contrast to many other SSD companies at the present time - he said:-
  • Nimbus is profitable,
  • their sales have tripled this year and
  • he expects sales to triple again next year
Being funded by customers - like a traditional business - means there's no urgency to rush to an IPO. Tom said the likeliest date he could envisage for an IPO would be towards the end of 2014.

We moved onto the subject of why enterprise customers buy SSD arrays - and we traded stories about some of the explanations which get tossed around like IOPS per dollar - which when you scrutinize them in any detail are ridiculous. We've both seen leading edge silicon SSD companies put nonsensical graphs into their marketing presentations which don't lead you anywhere useful in the real world if you follow the superficial analysis. (That's because these vendors don't make systems - and are many steps removed from genuine enterprise thinking.)

Tom said most of his customers couldn't tell you how many IOPS their apps were demanding.

I said I've been writing about the "cost of satisfying a given number of virtual users for a particular type of app" as being a useful comparison figure (for storage). We both agreed that even if enterprises don't know for sure what their throughputs or IOPS are - they have a good idea of how many users they're trying to serve within their organization or at customer facing web interfaces. The payroll tells you one, the marketing people can tell you the other. And accounting can tell you how much it all costs. You don't need storage analyzer tools to get a feeling for where the ground level lies.

After we had been talking for about 40 minutes I said - what was it you originally wanted to talk to me about? - because I knew this conversation had been set up to coincide with some sort of announcement - but I hadn't seen any details yet. Tom said he knows that after talking to me for over 10 years I rarely look at any briefing documents in advance and when I do I never stick to any planned presentation agenda - so he hadn't sent me anything.

But as our conversation had already veered towards the subject of a simple way that users can compare the costs of SSD storage for particular types of apps - and as I'd asked the question - he said there was a benchmark called IOmark-VDI which Nimbus had participated in recently with the Evaluator Group. He said he went into the process because he thought it might be a good thing to try out - and was gratified to found out that it shows the Nimbus product in a very good light with a cost under $40 per virtual desktop (pdf) achieved by a 2U Nimbus system supporting up to 4,032 linked clone VDI images. So that was a good note to end on.

Now - if any of you have seen Tom's SSD blogs - then you'll know that he's been averaging somewhere between one and two a year. And a few minutes after our conversation had ended - and while pondering these various matters I thought of a good way to summarize things.

So I sent Tom this email - "when I see you updating your blog on a weekly basis I'll know that your IPO date is impending."
Nimbus brings flash SMART plus stats to SSD rackmounts
Editor:- March 25, 2013 - Nimbus Data Systems today announced new software APIs which support its proprietary HALO OS based family of rackmount SSDs - and report on hundreds of real-time and historical metrics such as:- flash endurance, capacity utilization, latency, power consumption, deduplication rates, and overall system health.

Another new feature is that sys admins can monitor their Nimbus SSD arrays via new apps on Android / Apple phones and tablets.

Thomas Isakovich, CEO and founder of Nimbus said the new software framework would enable cloud architects and enterprise customers to gain greater insight into their flash storage by viewing internal aspects of their flash storage which mattered to them - rather than simply relying on benchmark indicators which have been cherry picked by vendors or reviewers
Nimbus ships 1 petabyte of SSD capacity / month
Editor:- January 22, 2013 - Nimbus Data Systems today announced it has been shipping at the rate of over 1 petabyte of SSD storage / month.
"Although we can hearken back to a simpler time when the SSD market was smaller and all the top players in it were private companies - which in fact isn't that long ago - one of the new realities of the SSD market is that there's nearly as much interest in SSDs as $$Ds (lucrative investment vehicles) as in SSDs as business improving technologies."

Nimbus does that "no spof SSD" thing
Editor:- January 31, 2012 - Nimbus Data Systems today announced its entry into the high availability enterprise SSD market with the uveiling of the company's - E-Class systems - which are 2U rackmount SSDs with 10TB eMLC per U of usable capacity and no single point of failure. Unified interface support includes 10GbE, FC, and Infiniband.

Nimbus software (which supports upto 0.5 petabytes in a single SSD file system) automatically detects controller and path failures, providing non-disruptive failover. The E-Class also supports online software updates and online capacity expansion. It has RAID protection and hot-swappable flash, power, and cooling modules. Pricing starts at $150K approx for a 10TB dual configuration system.

Editor's comments:- Nimbus seemed incredulous at my immediate reaction to the preliminary info they sent me. I said I knew of competing shipping SSDs which were denser, faster and offered more HA features too.
