I had been wanting to learn more about the internal
thinking in Innodisk for some time- as I could see in glimpses of technology
which appeared in their products - that there was evidence of original thinking
there - and significant investment in unique controller IP.
know the details and wanted to learn more.
So I requested an SSD
conversation with Charles
Tsai, Senior Director - Innodisk - and we spoke for about an hour on
topics like new ways to design enterprise flash arrays and about new ways to
make industrial SSDs better which borrow concepts from cloud architecture.
led me to re-evaluate - not only my assessment of the company - but also change
my opinion of what they were doing in the rackmount SSD market too.
had been very dismissive in my comments about - Innodisk's FlexiArray - when
the company launched that product in
November 2013 - as
you can see from my archive comments in the original news story.
that was one of the first things I brought up in my conversation.

why I changed my mind from a negative to a positive opinion) in the article -

company is part of a new set of trendsetters in the SSD market who - learning
from the experience of many customers (and in particular big cloud / web
users) are now starting to partition their flash management functions in a more
powerful and flexible
way - so that the responsibility for some actions is decided at a higher level
in the firmware - rather than simply dumping everything onto the controller
inside the drive - which doesn't have the same visibility of what might be
happening in other SSDs - or upstream in the host requests.

InnoDisk announced the

- C.C. Wu -
Director - InnoDisk -
presented a paper -
Comparisons of SLC, MLC and eMLC (pdf) - at the Flash Memory Summit. Wu's
paper - which compares data for several generations and brands of SLC flash -
confirms what some SSD makers had been telling me since the early 2000s (as
reported in my SSD
endurance article) - which is to say that SLC in reality has often been 5x
to 20x better than specified in the chip memory datasheets. The same is
not true for MLC - however - which presents greater risks of data loss when
suddenly turned off - which in turn requires better
architecture to recover and automatcially heal the data.
In September 2011 -
InnoDisk claimed in a
news story that its MLC based, .EverGreen Plus Series has a lifespan which is
7x longer than traditional SLC SSDs, and 140x better than conventional MLC SSDs
- due to a combination of features in its SSD architecture.
In March 2013 -
it will ship industrial
SATA SSDs in Q3 using
its iSLCT technology - which repurposes MLC as emulated SLC to get 30k write
from 3k standard cells.
In November 2013 -
InnoDisk entered the
rackmount SSD market
- saying it will demonstrate its
1U and 2U racks later this month at the
SuperComputing 2013 conference.
- InnoDisk announced
full scale production of its nanoSSD (a tiny industrial SSD) that conforms to
JEDEC's standard (MO-276).
In November 2014 -
spun off the business unit associated with developing and marketing its
FlexiArray systems (1U InfiniBand / iSCSI 10GbE enterprise flash arrays) into a
new company called AccelStor.
- InnoDisk won a
design excellence award for its ServerDOM SSD product concept.

Among other things in this article Wu cautions
readers about the limitations of encrypted SSDs...
"As strong as
the 256-bit AES encryption is on encrypted SSDs, it only protects data at rest,
i.e., when the system is turned off. To protect data in flight,
data-loss-prevention (DLP) techniques, use of secure communication protocols,

|How adaptive is the SSD
behavior to changes within itself? |
All SSDs rely on processing data
about the quality of the memory as part of their normal data integrity
They wouldn't work without it.
But some companies have SSD IP sets in which knowledge about different
parts of the SSD can be optimized and fed back to control and enhance SSD
functionality over and beyond the standard accepted SSD function block
The degree to which this passing of the intelligence
(regarding the state of past and future anticipatable data flows, priorities
of the application and the flash array's own readiness and healthiness
condition) can impact behavior in other parts of the SSD - is what I call
adaptive intelligence flow symmetry.

10x endurance industrial MLC SSDs|
|Editor:- March 28, 2013 - InnoDisk today
it will ship industrial SATA SSDs using its
technology - in Q3.|
iSLCT repurposes the 4 states of classic
MLC memory into 2 virtual states (with better signal integrity) effectively
emulating SLC in MLC.
This delivers 10x better endurance than MLC
(30K from "3K" MLC), faster write performance (nearly 2x as fast as
MLC and 85% of SLC speed - at competing geometries) and lower cost than using
SLC to achieve the same capacity (in current and projected market conditions).
Editor's comments:- I mentioned this technique several years
ago in a spoof SSD story - but what was once SSD fiction has become market
reality due to the divergent market
prices of different
types of flash memory.
