Pivot3 acquires NexGen
Editor:- January 27, 2016 -
today it has agreed to be acquired by Pivot3.
Editor's comments:- The last time I wrote about Pivot3 was 7 years ago.
I had a 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).

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.
Editor's 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.
consumer market -
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- it doesn't matter if the product is withdrawn from the market after a year or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.
Unified Storage in the SSD Age

company is broadly in line with that of other people.
awareness, financial reports and online search data - intrinsically provide
different numerically weighted views of the same market. And which methodology
you prefer depends on whether your priority is in understanding the past,
present or future - and what it is you're trying to decide.
longitudinal market studies you can refine your understanding of shifting
patterns of market change and real leadership by comparing these different
types of data and correlating the movements in different time periods. So a
shift in search volume in one period may correlate to a change in revenue some
time later. Or a change in revenue or profitability might be seen to be tied to
a change in brand strength later.
The interesting thing about the SSD
market is that because the technology hasn't been standing still - it can be
shocking to compare the same list and see how it changes over a period of 3 to
5 years and to see which old names have disappeared and which new ones have
replaced them. I'm often reminded of this when I trawl back through my own
and news archives. I'm sure it's the same for many of you too.
the things we all hope to get out of these lists - is to avoid making too many
bad bets on companies and technologies which will prove to be a waste of our
SSD market analysts,

February 5, 2013 - I often hear from readers designing
software for SSDs who

spent too much time over-worrying about internal SSD hardware details that
they really shouldn't be worrying about. Because by the time they learn about
such things - that type of hardware anxiety is ancient history.
I came across a recent blog by Chas. Dye at Pure Storage

that should never influence the block size decision is your storage subsystem."
comments:- I'd certainly agree that trying to slavishly make your data

probably a waste of time - because unless you know the SSD designer you don't
really know what's going on - and the abstraction you read about in some web
