Editor's comments:- both

the SSD ecosystem (no pun intended) insofar as they supply communications and
interface chips which connect SSDs and SSD boxes rather than having anything too
much to do with memory related controllers.
I imagine the regulators

update on the readiness of non flash NVMs to participate in SSDs
May 27, 2015 - In various interview clips in a recent article -
NAND, MRAM, RRAM: Emerging opportunities and challenges in
Solid State Technology - the author Paula Doe
reports how some of the contenders to
flash memory see their
roles within the SSD ecosystem. For example:-
- "Demand for ST-RAM is coming from buffer storage applications, such
as high-end enterprise-class SSDs..."
Some of these applications have been intuitively
obvious for some while - but this article gives a better idea of commercial
readiness and an indication of whether the next generation problems are being
tackled in a fast enough timeframe to be relevant to the
SSD market. ...read

SanDisk hit by lawsuit re tardiness of adverse business
Editor:- May 27, 2015 - Unwelcome news for SanDisk today from an
announcement that a
class action lawsuit has been commenced on behalf of an institutional investor
re ("SanDisk") (NASDAQ: SNDK) publicly traded securities during the
period between April 16, 2014 and April 15, 2015 (the "Class Period").
law firm leading this Robbins
Geller Rudman & Dowd LLP alleges, among other things, that during
the above 1 year period SanDisk did not openly disclose it was experiencing
production qualification delays "on certain key products... and may also
have concealed problems associated with its acquisition of
which could be assumed to affect the market price of shares) yet that during
the above period the plaintiff asserts that directors were able to sell over
$35.8 million worth of their SanDisk stock."
comments:- A lot can happen to any SSD company during a year - especially
one - like SanDisk - which was working its way through repurposing some
inherently business transformational acquisitions at the time mentioned above.
One of the key characteristics of the SSD market in recent years (see
examples here - what changed in
2012 etc) has
been that assumptions which seemed reasonably cautious at one point in time -
can soon lose their validity or significance - due to the unpredictable market
interventions by imaginative (or lucky) competitors.
It seems to me
that unless publicly traded SSD companies issue daily updates on the internal
setbacks they encounter (which would educate their competitors and therefore be
prejudicial to their own shareholder interests) then directors of such companies
can't safely sell any of their shares until after the whole market has settled
down into a more predictable pattern - which by my guess - can't be till after
Hard to see how any company could operate under such
constraints. Which means that lawsuits are an inevitable consequence of doing
fast growing Nimble comments on perceptions of being a hybrid
storage supplier in all flash applications
Editor:- May 26 , 2015 -Nimble Storage today
that revenue in its recent quarter grew 53% yoy to $71 million.
call (transcript) - Suresh
Vasudevan, CEO said, among other things - "the
hybrid market we are
competing in is roughly $10 billion, growing to about $14 billion as per
IDC's estimates over the
next 3 - 4 years... the frequency with which we compete against all-flash
alternatives has increased and our win rates are indeed high... However, when we
do lose against all-flash alternatives, it's typically 2 things happening
"One, the customer has a singular application
where they've taken performance challenges and the customers saying I want to
solve the needs of this particular database or this particular application. And
the customer has by and large selected all-flash arrays as the answer for that
point need and that's often where we find that we are taking perception
challenges as much as to the reality of what our platform really does."
comments:- Another factor for hybrid companies like Nimble, Tegile etc -
when viewed from the context of some high end all flash applications - is
that much of the functionality of their tiering software is considered to be
irrelevant or simply adding to the cost and latency. This is a
and positioning problem which isn't entirely answered by adding AFA models to
the product line.
The long term strategic question for all storage
box vendors - when seen from the perspective of
consolidation thinking - is to choose how they will position themselves:-
either as a strategic supplier of raw white box hardware or as an integrator or
software supplier which collaborates with someone else's standard boxes .

footprints of 2.5" NVMe SSDs is a critical detail when considering the
design of dense storage arrays so I asked Scott Harlin,

included a few items to address these concerns:
1. - Temperature sensing and thermal throttling to maintain
consistent operating conditions even under adverse temperature variances
2. - User-selectable power envelopes, in 15W, 20W and 25W
settings, reduces wasted power when maximum performance is not required while
efficiently addressing temperature requirements in support of a variety of
3. - An innovative 'flow-through' case design enables more
airflow to critical components, keeping the device cool while reducing airflow
Editor's comments:- that user selectable power envelope- in graduated
steps - seems like a really useful design attribute. So I'll be watching out
for it in future arrayable SSD launches.

Toshiba demonstrates 3.5" ethernet hybrid
May 18, 2015 - Toshiba
demonstrations of a new hybrid drive which combines HDD and flash in a
3.5" form factor
with an Ethernet interface.
comments:- for reasons which were obvious to systems architects 10 years
ago - and haven't changed today - you will always get better control of
performance and cost by designing a
hybrid storage array
with distinctly separate HDDs
and SSDs compared to combining both these functions in a single type of drive.
the dream of combining these functions in a single drive to add value to hard
drives does re-emerge in different guises from time to time.
only merit I can see to such a product - as the new hybrid from Toshiba - is
that if you have very simplistic and primitively designed systems
with using large arrays in a single type of applicaton - then combining both the
flash and magnetic storage in a single drive could simplify the
aspects of the design by spreading the risk and consequences of drive failures
in a homogenistic way which makes writing the software easier.

where we've seen most of the past market experiments with
- it doesn't matter if the product is withdrawn from the market after a year or
so - because the design costs only have to make sense for a brief window of
But in the enterprise market - the risks of
committing an array design to a drive type which is single sourced and hasn't
got an independently arguable credible future roadmap means that such system
implementations are rare.
