say farewell to reassuringly boring industrial SSDs
this is not your Grandfather's industrial SSD marketby

blog began this morning as an update about - where we are with
industrial M.2 NVMe PCIe SSDs - but it grew into something else.|
industrial M.2 NVMe PCIe SSDs etc
One of the new emerging
markets for industrial temperature SSDs in 2017 is high performance NVMe PCIe
SSDs in the
M.2 form factor.
can judge the newness and size of this market by the fact that when I researched
the availability of production products in this category earlier this year I
was only able to confirm 2 manufacturers with products:- Foremay and Virtium.
the other industrial M.2 SSDs I found at that time were good old SATA.
I expressed my surprise about this in a news story in
March 2017. The
headline if you look it up was - M.2 PCIe SSDs for secure rugged applications?
- you may have been less surprised - because (apart from the applications need)
you would rightly say that the other side of NVMe PCIe adoption is the
availability of suitable industrial grade host resident
controllers and server
When you have enterprise grade throughput and IOPS
aren't you also straying into the kind of power guzzling territory which is
anathema to most industrial equipment designs? More power, more heat, less
reliability - you know the score...
Well that circle was squared
neatly in a news story in
April 2017 -
which I tagged with this headline - now Cinderella industrial systems with "no-CPU"
budgets and light wattage footprints can go to the NVMe speed-dating ball.
story was that about a new FPGA controller IP for industrial PCIe
applications - from IP-Maker
who claimed it could deliver enterprise performance while obviating the need
for a watts guzzling processor. (Or sometimes any processor at all.)
just as interestingly the briefing notes in the news pack described some of the
new applications which the new technology will help to make more feasible.
know from experience that "applications notes" from controller and
processor companies are often founded on wishful thinking rather than hard
reality. And I expect that - given the imagination of systems designers - we may
find that the biggest roles for industrial NVMe PCIe M.2 SSDs may be something
The wishful thinking effect is also part of the
fuel and inspiration for companies in the
storage market research
business. If you want numerical guesstimates for SSD shipments (to confirm
or inform your own guesses) before you embark on your next SSD project that's
a good place to look.
other changes coming
looking at strands of upcoming change in the industrial SSD market - the
embracing of high speed products is just one dimension. Other degrees of
freedom I expect to report more about in news stories include:-
- the use of much larger memories in IoT leveraging architecture and IP
from phones and the cloud.
This has been a long time in coming.
And isn't here yet.
I included this as a
for 2016. And 2 quarters later Marvell's FLC
technology looked like an early match in that development stream. That was 1 of
only 4 path lighting SSD technologies which I picked for a
mention at the end of 2016 which I had encountered across all SSD
application markets - not just industrial.
Don't expect too much too
soon in tiered industrial memory, however. Even the better funded tiered
memory market for the enterprise has been slower to ship products than
expected due to a proliferation of competing solutions arising from the
SCM DIMM wars
market pulling in
directions and centered around multiple memory types.
Some of the
contenders in the enterprise nvm market may not even be suitable for industrial
temperature operation yet (for example Micron's 3DX) whereas
other nvms with high temperature remanence and possibly even good radiation
resistance (such as Everspin's
MRAM) haven't got the density (Gb per chip) to provide a complete solution
and need to be supplemented by a tier of flash.
One thing I can say for sure about the future of
the industrial SSD market is that the industrial rugged world is everywhere -
and as the world moves to being able to value data wherever it may originate or
be needed - and as new memory technologies evolve and get proven from the
high stakes enterprise casinos - we're going to see big revolutions coming
in the traditionally staid and conservative industrial data systems market.
- discarding the conventional industrial market wisdom and exclusive
reliance on the "solo SSD".
Industrial SSDs have
traditionally been used as solo devices. This saves space and power but places
great dependence on the reliability of each single SSDs. And you know what that
does to the price.
enterprise learned decades ago that incorporating
array concepts for self
repair and reliability enables systems reliability to be created from
architecture and management and doesn't depend critically on the
reliability - or
cost - of any single drive.
But hey - they've got big racks and big
power supplies and engineers (or robots) who hang around day 24x7 sipping
coffee (or electricity) itching to plug in new upgrades and replace faulty
That's in contrast to the typical industrial market when space
and budgets are tight.
For the industrial market I think the array
direction is a story which will unfold and change the industry during the next
It's easier to see how this would work at the high
wattage and high data processed value end:- simply as the evolution of the
But at the low wattage end - in cars and IoT feeds
- it will require the integration of processors and persistent memory at the
SoC level and entirely new product architectures.
It may be that the
array level industrial SSD will always have to be a
rather than a standard COTS product - because weighting the internal design
factors in software repairable industrial drive arrays will be very
applications dependent and a slippery moving target compared to the stark
simplicity that if everything depends on a single solo industrial SSD then it
had better be good.
This will not be your grandfather's industrial SSD market.
with SSDs everywhere it's likely that its importance in financial terms will
