40 years of thinking

|Editor:- November 21, 2018 - I can only recall a
couple of occasions when an SSD company has gone back into stealth mode - and I
so my curiosity was piqued by a note on the
page of NVMdurance
- which (in listing some of the impressive milestones of this company which
pioneered and patented IP related to the machine learning characterization of
flash) concluded with this...|
"2018 - Key Machine Learning IP
acquired under NDA, NVMdurance goes into stealth mode."
There's a story here - I thought - some of which was guessable - but I was
looking for more than conjecture and so was delighted to find rather more
than I had expected in an article - published last month in the
Dublin Globe -
an exit isn't all it's cracked up to be - by
Gordon Hunt -
which is based on an interview with Pearse Coyle (who was CEO
of NVMdurance between 2012 and 2017). '...read

2018 - GridGain began beta sampling its in-memory cache as a cloud
2018 - Intel and Micron agreed to a parting of the ways on future
Upto that point Micron had seen minimal revenue
from 3DXPoint whereas the potential of developing a software ecosystem centered
around this technology had strategic lock-in attractions for Intel regardless of
near term memory sales. Zsolt Kerekes - founding editor of StorageSearch.com
suggested "the memoryfication of processors and the flattening of latency
by SSD infrastructure means that traditional complex multi level cache server
processors are wasteful... and that due to trends in memory accelerators for the
defined software market... memory and processor companies (like Intel and
Micron) will in future have more reasons to become competitors rather than
collaborators in strategic designs in the cloud."

Editor's comments:- maybe you've got your own
ideas about what these strategic splits should have been. And maybe you would
have thought of a better title too. This may be my last major article about
SSDs - so I packed in as much as I could.
sanitizing sensitive SSDs? heed my words oh prideful SSD
dust you were born
and unto dust you shall return
|Editor:- September 25, 2018 - A reader - Simon Zola
- Manager, AVTEL Data
Destruction emailed me last week after seeing my recent home page blog -
back at my 19 years of writing about the data recovery market - which I
concluded with this.. |
there an opposite concept to data recovery?
The flip side to data recovery is fast purge SSDs and
Simon said - "I have only just come across you
and your site and I would love to hear your opinion on meaningful data
sanitisation of SSD."
thought to myself how many years is it since I set up a dedicated
SSD fast erase / purge
page? - I checked. It started in 2009. (This is one of the joys and
frustrations of the web. Frustration - that you can't find stuff which has
been around for a long time - because it gets drowned by social chit chat. Joy -
in knowing that there must be a lot more readers out there who also care about
the same problems.)
Anyway - what I said to Simon was - "There is
a double digit list of standards by defence and government agencies which cover
various use cases and whether the drive is desired to be redeployed for another
project or not. The purpose of extreme autonomous SSD purge is to destroy enough
critical chips in the encrypted SSD so that if it falls into the wrong hands
(captured by enemy) then the SSD data will remain immune to the best
efforts of forensic data
recovery. Thats just one reason why DR and security agencies intersect and
are mutually aware. But as DR gets better then sanitisation has to advance too
(best way being destruction of the chips)."
Anyway Simon - whose
company does Onsite Physical Destruction of HDDs and SSDs in Australia pointed
me towards an interesting
video - re Mobile Data
Destruction which shows the type of thing his company does. It's on
youtube which means that many of you won't be able to see it right now if
you're viewing this at work.
So I'll describe what happens...
The video shows a van which arrives at your site and delivers via a conveyor
belt all the drives you want shredded - presumably while one of your security
people watches it happening. (You'd have to verify the exact design and chutes
etc yourself obviously to satisfy yourself there are no magical trap doors - or
maybe you could just rent the facility. It depends on your own circumstances.)
That prompted me to realize that it had been about 2005 when I had
last written much about the
services and equipment business (as opposed to autonomous drive purge)
because in a way - once you know what needs to be done - what more can you say
about it? But maybe that page could do with a refresh - which is why I'm writing
We are much more sensitive and vigilant about environmental
impacts nowadays (2018) compared to the start of my own career (1977) when
many of the industries which paid the wages of our local communities and
where our friends and neighbors and customers worked were inevitably sometimes
spilling stuff into the sky, ground and water.
So I said - Hi
Simon - I forgot to ask this... how is the shredded material from the sanitized
drives processed? I mean the cost from an environmental hazard point of view?
Simon said - 0 to land fill. (And then he gave me a list of who
reprocesses what afterwards - which you can find out more about on his web
Editor's comments:- I'm guessing that wherever you live you
might be interested in the possibilities opened up a mobile service like this.
My own modest needs in this category have always been simply
managed by the expedient of a log splitter or ax - but I'm only smashing one
drive each season or less. Some of the kids of family friends have made
artworks out of the little chunks of smashed up drives and mangled chips.
dustry grains are less artistic but better from the security angle.
|If you could go back in
time and take with you a factory full of modern memory chips and SSDs
(along with backwards compatible adapters) what real impact would that have?

Princeton's in-memory accelerator uses switched caps to take
neural matrix MACs out of the digital box
Editor:- November 22,
2018 - In memory computing acceleration is one of those architectural ideas
which - continuing in the footsteps of the
era of SSDs - now looks well placed to be the focus of creating
which leverage the new loci of latency unbottlenecking opportunities
revealed by the incremental memoryfication of data processing.
recent years we've seen advanced design groups leveraging algorithm aware
approaches to neural network processors which enable them to usefully deploy low
resolution MACs (such as Google's TPU).
And stretching this idea
outside the binary box some hybrid implementations have mixed analog and
digital computing elements.
For example the ReRAM ML engines
mentioned in 2 news
stories in May 2018.
Similar to that vein of thinking - but using
different underlying technology - researchers at
Princeton University recently
published a paper (a Microprocessor
implemented in 65nm CMOS with Configurable and Bit-scalable Accelerator for
Programmable In-memory Computing (abstract) /
which describes a new type of in-memory-computing accelerator which is
integrated in a programmable processor architecture which uses charge domain
compute elements built around 8 bit resolution ADCs and switched capacitors to
perform multiplication and accumulation.
The authors say their 65nm
CMOS reference design of a 590kb in-memory-computing accelerator shows an
energy efficiency of 152/297 1b-TOPS/W and throughput of 4.7/1.9 1b-TOPS
(scaling linearly with the matrix/input-vector element precisions) at VDD of
the paper (pdf)
In a related non technical interview article
by Princeton communications -
memory and computation, programmable chip speeds AI, slashes power use -
one of the researchers - Naveen Verma
- Associate Professor of Electrical Engineering - says (among other things)...
computing has been showing a lot of promise in recent years, in really
addressing the energy and speed of computing systems. But the big question has
been whether that promise would scale and be usable by system designers towards
all of the AI applications we really care about. That makes programmability

university researchers disclose delusion of security blanket
delivered by popular self encrypting SSDs
Editor:- November 8,
2018 - Researchers at Radboud University, in
the Netherlands have recently
a paper - self-encrypting
deception: weaknesses in the encryption of SSDs (pdf).
conclude - "we found that many hardware implementations of full disk
encryption in SSDs have critical security weaknesses, for many models allowing
for complete recovery of the data without knowledge of any secret... This
challenges the view that hardware encryption is preferable over software
encryption. We conclude that one should not rely solely on hardware encryption
offered by SSDs."
After discovering the ineffectiveness of the
protection offered by the encryption hardware in the models affected - the
authors alerted the authorities and agreed to wait 6 month before publishing
their paper so as to enable the manufacturers - whose products had been tested
(Micron and Samsung confirmed the vulnerability issues) to work on firmware
The paper also examines commonly held assumptions about the
security of encryption engines in various states when analyzed from particular
attack directions. ...read the
Editor's comments:- as with all
aspects of SSD design
- the correlation between what the customer expects and what does actually
happen in the real world depends on the quality of the designers and the
verification process. That's why it's not unusual in mission critical projects
SSDs for the customer verification process to take longer in elapsed time
than it took to design the original SSD.
