Barry Whyte's new blog says among things:-
storage development team in Hursley started work on the design of a new
generation box back over 3 years ago when I was still based in the UK. The idea
was to build a low rack density, and high performance control enclosure that
could take NVMe Flash drives, both in terms of NAND Flash based, and look to the
future of SCM technologies, such as 3D Xpoint, Z-SSD and whatever else will
come along." ...read

I asked Thomas Isakovich,
CEO and founder of Nimbus some questions about the new ExaDrive technology.
Editor - The
announced by your flash partners last year used planar 2D flash. Does
the 100TB family use 3D flash? Knowing the answer one way or another will
enable some people to make their own judgements about incremental upsides in the
next year or so's roadmap. And also form a view about specification stability
Tom Isakovich - Yes 3D flash for the ExaDrive DC.
- The issue of cost per drive is an interesting one too. But the companies you
were working with last year have experience in processes which can produce a
high confidence reliable SSD for high value, mission critical markets (like
military) in which the reliability of every single SSD is critical. So my guess
would be that for integrators who have a serious interest in the ExaDrive DC100
they will be looking at the cost of drive failures on a system population
basis and the value of less drives and less heat per TB is more important
than the headline cost of a single failed drive.
Tom Isakovich - I have
an interesting subject for you to consider on the topic of "reliability".
Namely, is an SSD any less reliable than an all-flash array? I contend that it
is not. In fact, an SSD is more reliable.
- Our ExaDrive DC has flash redundancy internally, with the ability to
lose about 8% of flash dies without any downtime, data loss or capacity
reduction. This is analogous to
RAID in a traditional
all-flash array that protects against media failure. So on the notion of media
redundancy, they are equally redundant.
I'm thinking more on this. But empirically, an SSD is more
reliable than a System. The user can achieve desired redundancy in their overall
architecture, taking this into consideration.
- The ExaDrive DC has a 2.5 million hour MTBF with no moving parts.
That is about 6 times longer than the typical all-flash array (which includes)
many active and moving parts. All-flash arrays have integrated power supplies,
active controllers, fans, and other components prone to failure.

Kaminario no longer wants to supply hardware
January 17, 2018 - 2017 was a difficult year for AFA vendors whose primary IP
was software - as they couldn't be sure how much they would have to pay for
their memory based hardware and couldn't be sure either if and when they
would get it. However, even without the
shortages it was inevitable that vendors would one day have to align
themselves with new trends

dawned for Kaminario

Western Digital buys Tegile

today that it has agreed to acquire Tegile. The price was
Editor's comments:- Tegile was already using a
customer of WDC drives (SSDs, HDDs and the InfiniFlash white box SSD array from
SanDisk). So Tegile's flexible pricing models for buying storage were already a
good showcase for how to integrate these technologies in a user friendly way.
of the business risks of Tegile's business model was that its ideal customers
were buying usable storage based on
model pricing and cost expectations which seemed predictable and scalable
upto about the tail end of 2016. Unfortunately those cost predictions have
been shattered and ruined by the rising prices of
and associated shortages in 2017.
A few years ago I discussed the
risks of the utility model with Tegile - which at that time seemed to be
containable technically (because they were obviously related to expectations of
reliability, learning from similar customers doing similar things and
efficiencies). Tegile's business model meant that external finance could depend
on a predictable curve of customer value and cost.
When memory prices
rise by 50% or more (instead of going down) those curves mean that repeat
customer sales can't follow smoothly from what happened before.

"It's widely known that Tegile was running out of cash. No

saw Tintri's horrific IPO and concluded that unprofitable storage companies are

reliability studies of enterprise flash done by
STEC - that many
flavors of flash controller management contained within them the seeds of
performance crashes which would only become apparent after years of use as the
data integrity algorithms escalated to progressively more retries and stronger
ECC to deliver reliable data from wearing out (but still usable) flash.
I agree with Jim O'Reilly. You do need more sophisticated datasystems

but for ALL external enterprise storage."
this result in the real world of market revenue tracking is broadly in line

memory intensive data architecture emerges in a new family of

Editor:- May 25,
2016 - 1 petabyte usable storage in 2U along with a
flash backed RAM
rich server family which uses patented CPU level aware cache-centric data
reduction to deliver high compute performance are among the new offerings
today by which has
emerged from stealth mode.
Founder & CEO, Symbolic IO - Brian Ignomirello, said - "This
industry hasn't really innovated in more than 20 years, even the latest
offerings based on flash have limitations that cannot be overcome. Our goal at
Symbolic IO was to completely redefine and rethink the way computing
architectures work. We've completely changed how binary is handled and
reinvented the way it's processed, which goes way beyond the industry's current
excitement for hyper-conversion."
Giving a clue to
performance Ignomirello said - "One of our early tests, allows us to
run a full cable class content delivery network over 80+ nodes, while streaming
80+ full-featured movies simultaneously on one channel and requires less than 8%
of the CPU capacity and we had plenty of headroom to run more. IRIS
(Intensified RAM Intelligent Server) is 10,000 times faster than today's flash."
comments:- I hadn't spoken with Symbolic IO (when I wrote this) but my
first impression was that the company is in line with at least 3 strategic
trends that you've been reading about on in recent years:-
company profile summarizes their capability like this...
IO is the first computational defined storage solution solely focused on
advanced computational algorithmic compute engine, which materializes and
dematerializes data effectively becoming the fastest, most dense, portable and
secure, media and hardware agnostic storage solution."
about the company's background see this article -
IO Rewrites Rules For Storage on .
From the marketing point of view it's interesting to see that
in its launch press release Symbolic IO positions itself in the
context in this way "IRIS... is 10 times faster than 3D XPoint."
IO says the new systems will be start to become generally available in late Q4

for such approaches in the future market consolidation roadmap because not
everyone needs the fastest performance. But many

good feeling about their
architecture thinking which was being applied to hard drive arrays but
I viewed it more as a valuable
efficiency boost to
buy breathing space for the
last gasp years of
enterprise HDD rather than the new direction I was focused on - which was
heading towards the solid state storage datacenter. And so - from my point of
view - I had nothing more to say.
On the other hand we're heard
times in recent years.
Combining the software and architecture from
these 2 companies could produce a platform with characteristics comparable to
the best upwardly stretched efforts of much better known competitors if
Pivot3 and NexGen can draw the integration boundaries in the right places (and
get it done quickly enough).

2008) had been coasting towards oblivious commoditization - has been
temporarily reprieved from that fate (2009 to 2018) by the disruptive
impact of SSD memory technologies which enabled the construction of
5 to 6 role
differentiated types of new storage boxes which could deliver value to
users in ways which were technically unimaginable and unfeasible with
classically tiered memory and storage.
Having misfired its original
entry into the enterprise flash market in
2008 - EMC has
in recent years managed to accumulate credible industry leading proprietary IP
and product lines in 2 of the 5 above storage box segments (which will satisfy
projected enterprise storage needs in the post HDD era) meanwhile treading
water in the other 3 main box segments (indicating its aspiration to occupy
part of those other crowded beachheads if possible).
Assuming all goes
well with the acquisition process - the Dell-EMC product line will enable EMC
storage to be more competitive in the short term with existing products and to
maybe credibly add another notch to the list of product types for which it has
aspirations for clear leadership.
on the server and storage markets which are emerging from
SSD centric software
and data architectures will mean that traditional product lines from both
vendors will shrink away.
And those lost revenues will stay gone
forever. The old ways and the
orders won't be coming back. That's why it's important for both companies
to draw in new smaller customers and to nurture them (if possible) into the
new sustainable sold state storage and server product lines.
about impacts for the SSD market?
Anyone who competes with Dell or EMC
will - for the next year - have an easier ride - due to the inward focus
which sucks away the attention of the talent following such acquisitions.
SSD market as a whole will continue to supply memory and SSDs to the new company
- and probably can look forward to getting more business in 18 months time.
it won't simply be more of the same. Some SSD vendors may see big changes
when Dell EOLs systems and modules which are cannibalistic and compete within
the combined product lines.

"more lanes of SAS than anyone else" - new 4U
Editor:- July 28, 2015 - As the
rackmount SSD market
consolidation - new business opportunities are being created for those
brave hardware companies which accept the challenge of providing simple
hardware platforms (which provide high density or efficiency or performance or
other combinations of valued technical features optimized for known use cases)
while also being willing to sell them unbundled from expensive frivolous
In that category - Savage IO today
its - a 4U
server storage box - which - using a COTS array of hot swappable SAS SSDs -
can provide upto 288TB flash capacity with 25GB/s peak internal bandwidth with
useful RAS features for embedded systems integrators who need high flash
density in an untied / open platform.
Savage IO says it "products
are intentionally sold software-free, to further eliminate performance drains
and costs caused by poor integration, vendor lock-in, rigidly defined
management, and unjustifiable licensing schemes."

fast rackmount SSDs from EMC, IBM, Pure... which is cheapest?
Editor:- July 9, 2015 - In a recent blog about the
competitiveness of fast rackmount SSDs -
I Hate Cost/GB Discussions - Michael Martin,
FlashSystems Specialist - IBM
- leads you through a series of arguments to convince you that - when
measured on a 5 year ownership basis (against a very specific set of parameters)
his company's fast
rackmount SSDs are cheaper to own than competitive models from EMC and Pure.
other things Michael says - "Why is everyone so focused on the initial cost
when it comprises such a small percentage of the "real" or total cost
of the storage array?"
condition question which Michael Martin looks at is - what is if EMC gave
you a FREE VMAX? How would that compare to the IBM V9000 FlashSystem's TCO?
I like that style of analysis - because it's one I've used a lot
myself in the past 12 years or so - in various market forecasts where I
looked at the cost of one type of product being zero but another type of
product (SSD) still being cheaper or better.
comments:- recently we've seen survey data from
Tegile suggesting that
for a significant proportion of enterprise users the ROI on their enterprise
flash investment can be as little as 1 or 2 years - which suggests that looking
at the 5 year cost, or the initial purchase cost are equally unreliable
For most users - the uncertainty of capturing reliable
predictive cost benefit data to justify the acquisition of enterprise flash
arrays was discussed in my article -
the Astrological Age of Enterprise SSD Pricing.
The reasons for
choosing one system over another include so
preferences and associated customer service values that the 5 year
predicted cost from a particular web site are not likely to be the decisive
factor for most users - who will prefer to trust their own analysis.
long as you don't take the rankings in Michael Martin's blog too seriously - as
gospel - and don't come away with the idea that IBM's FlashSystem is always the
best and cheapest fast rackmount SSD - it's a fun read. ...read
Conspicuously absent however in this discussion -
given the 5 year cost justification timeframe - is a new class of fast
rackmount SSDs which will be emerging in the next year - based on arrays of
2.5" NVMe SSDs
- which will have the same impact on this segment of the market (IBM, EMC,
Violin etc) as did
flash on RAM SSDs.
(Implode the costs and explode the scalability and market roadmaps.)
