| 1/3 of Micron's nand flash trade sales go
Editor:- December 20, 2012 - Micron today
that revenues from sales of its NAND flash products were 4% lower in the
quarter ended November 29, 2012 than they had been a year ago.
volume of the company's nand flash decreased by 9% - but average selling
prices increased 5%. Overall Micrion reported a net loss in the quarter of $275
million on sales of $1.8 billion.
Micron said that SSD shipments had grown 20% compared to the previous
quarter. SSDs are 17% of Micron's nand business and the company estimates that
35% of the nand flash it supplies to trade customers end up in SSDs. MLC
was about 80% to 85% of nand flash wafer production with SLC and TLC making up

increasingly seeing eASIC devices being selected as platforms for enterprise
grade customized flash controllers," said Dr. Andrei Vityaev, CEO
at Proton Digital. "In enterprise storage systems, production volumes are
often not high enough and the market changes are too dynamic to justify
cell-based ASICs but performance and low power requirements are beyond the
capability of FPGAs. This makes an eASIC
solution ideal for this space."

I think this problem is going

new technology and architectural features creeping into SSDs which could
introduce new weaknesses and vulnerabilities which don't show up on current
And that's before you even introduce apps and
optimizations. Customers may say - I don't care if this SSD's performance drops
off in an application which I don't have - because it's the best in the app I

As we approach 2013
anyone looking for a fast

strong contenders to choose from - which don't have SF inside. So even
if the enterprise SSD market doubles - the cake is being sliced in more ways.
This analysis isn't new. I said something very similar on these pages

closer to 2-3.
On the other hand if you consider any of the
projections for continuing enterprise SSD growth - fighting for control of
the cake slicer is really worthwhile.
who are the ideal customers for BiTMICRO 's new (but late to

target market for the maxIO product line includes what I call

the closest product to the maxIO is the
Texas Memory Systems -
which is now part of IBM. Closest insofar as it's got one or more ultra fast
central controllers which expand via data movers / intelligent I/O peripherals
which fan out to more flash.
One of the problems I see for BiTMICRO
though is that - because it's so many years late coming into the enterprise
PCIe SSD market - it will have to focus its efforts on a very restricted set
of technical customers who want to better the performance they can get from
arrays of small architecture PCIe SSDs (like those in established PCIe SSD
products from OCZ and
LSI) and who prefer to
use their own software
and who don't want to get tied into
APIs - and who also like the idea of raw brute peak performance rather than
the predictable rounded performance of
customers who maybe would have been satisfied with a RamSan type of product -
but who either see themselves as competitors to IBM or want to retain the
option of buying their critical supplier (BiTMICRO) or having large share of
mind of that supplier if the maxIO product becomes strategic in the customer's

SSD HDD ratios in big data? - blog by Panasas
December 11, 2012 - "An important piece of our research involved
determining how much SSD capacity customers would need...
whether it would make a big enough difference in system performance to be worth
the incremental cost of
including SSD storage in the system. To do this, we extracted key data from
production file systems in the field..." - says
Sr. Director of Product Marketing at Panasas in his recent
blog - in which he also says that in HPC
workloads users can get good enough results by using as little as 1.5%
ratio of SSD to HDD - compared to (read his blog if you want to see the exact
ratio) needed for financial and other markets.
comments:- Although I was told about the earlier episodes in this blog
series - which includes an
- I didn't mention them before - because I assume if you
don't already have a good idea of
what's an SSD?
before you get to these pages - then you won't linger here very long.
reason for my earlier reticence about these Panasas blogs - is I think that
a description of SSDs written from the viewpoint of an
SSD ASAP company
whose boxes average over 90% hard drives - may be subtly tilted to a
perspective which I consider to be a sideline along the
enterprise SSD adoption
road rather than the straightest way to the final destination.
- to give credit where it's due - some of the other past blogs I've seen from
Panasas have included valuable insights which are storage media agnostic.
I've said to a couple of readers recently (including a Panasas
customer) - that if I had to make a list of the last 5 companies on this planet
which I thought would still be shipping hard drives in arrays into the
enterprise - then Panasas would be one of them. That's because a small group of
companies have invested enough talent into new ways of managing large HDD
populations in a more effective and efficient way than the small controller
architecture of classical RAID
It will be lonely for the HDD array sales guys when that
happens though - just as it has become quiet lately in the

Nimbus blog seems fixated on EMC's XtremIO

of my SSD ramblings and want me to clarify this stance - it's simply because
EMC's response to the SSD business model - in the modern SSD era - has been
reactive and therefore has been pragmatically weighted towards
engineering and software integration - which if you know the company's
history - looks a lot like what they were doing since the

very successful business strategy for them. When all the hardware components
are the same for everyone (as they were for 20 years in the
HDD array market) then
it's the software and services which make the enterprise difference. We haven't
got to that level of stasis yet in SSD hardware (and are nowhere close to
fossilization) - which is
one of the
reasons that leadership in the
SSD software market is
still up for grabs too.

SSD goodness is bad|
|Editor:- December 5, 2012 - The
cost of SSDs is one
of the arguments most often cited by antis to explain why (in their view)
the transition to a pure SSD storage market can't happen.|
the designers of the first ships made from iron (which unlike wood doesn't
float) and the first airplanes (which were heavier than air) must've got used to
hearing similar objections.
In the past 10 years in various articles
I've described what I thought were the real
propositions for SSD adoption in different markets. And I've got so used to
filtering out the inappropriate arguments about the cost per gigabyte of SSDs
which come from anti-SSD vendors and from those many
storage market researchers
who still don't understand what SSDs are about. These nonsensical blog posts
and white papers about SSD cost justifications don't upset me as much as
they used to - because there will always be crazy stuff on the web.
the broad sweep of principles which govern SSD adoption in the enterprise still
leaves much room for misleading analysis from those who should know better,
when that mistaken analysis comes from leading SSD vendors - then I feel it my
duty to show that it's
So be wary of arguments for enterprise SSD
adoption which cite IOPS per dollar (or the other way round) as a
justification for filling a gap in some cleverly drawn curve.
seen this recently from leading SSD companies who should know better.
human beings we feel comforted when we think we see new patterns. But they
don't always reflect reality. SSDs fitting gaps in IOPS vs dollars charts
isn't a sufficiently good reason to buy SSDs. Just as buying stocks based on
past performance charts isn't a good idea either. The future isn't a tidied up
remake of the past.
If you think about it for more than a microsecond
you'll see that the IOPS per dollar argument - which sounds plausibly
eco-technical when you first see it written down - doesn't lead to any
safe conclusions at all.
the zero cost but slow SSD fails this
analysis to the situation and imagine an SSD which costs zero dollars.
According to the IOPS/$ advocates - this is your perfect enterprise solution
and at this cost it should even replace hard drives. But if the IOPS of the
SSD is considerably less than that of the hard drive - you'd be nuts to use
it - because you wouldn't get useful work done on your apps. (The model has
broken down in this direction.)
ultrafast SSDs with low capacity
fail this test too
At the other end of the scale - it's easy to
picture ultrafast SSDs which could score very well on the IOPS / $ scale - but
whose capacity or electrical power consumption or or physical size or
reliability doesn't make them scalable or attractive solutions.
recently on these pages that if you're going to try and come up with a single,
plausible-sounding eco-technical marketing-jargon metric for SSD adoption
in virtual server environments - then a better suggestion is "cost per
happy virtual user". That's the total system cost BTW (TCO) - which
includes all the servers and software licenses and service costs etc etc.
per dollar is a useless metric
Once you start looking at complex
real-world systems - which run more than a single type of app - you'll see that
the only way in which users can optimize their total economics is by
mixing and matching different speeds of SSDs in what I call different
silos in their apps
Even if you haven't read that read that
article it's easy to grasp why I say you can only get the truly lowest
system cost by using different types of SSD with different speeds,
different capacities and different operating characteristics (and certainly
different $/IOPS) - within ratios which make sense for that type of app mix and
$/IOPS is an illusion which doesn't take you anywhere far.
- everything above - up to this point here - is something I've already said or
implied before - so what can I leave you with on the SSD news page today which
Well here's something I've been thinking about.
SSDs may reduce the amount of SSD capacity you need in a well designed VM
environment - compared to using slower SSDs - for the same number of users. The
reason is that while there is some overhead in capacity which you can't avoid -
on a per user basis - such as their unique data - there's also a lot of
transient system storage capacity which gets allocated and deallocated
dynamically to get their work done.
As we know in the hard drive VM
world - at the threshold of usable performance you need more capacity (really
- more drives) simply to get enough IOPS performance. The HDD experience is
the best sales person for introducing SSDs.
But when you're comparing
different types of SSDs in a VM situation - then the software makes a big
difference too. If an SSD from vendor X is twice as fast as that from vendor Y
- it means that SSD-X frees up some of its capacity faster than SSD-Y and can
therefore handle more users for the same purchased capacity within the same
How big is that percentage difference?
we'll see more competing claims coming out from the
SSD software industry
in the months ahead.
...Later:- several years later - due to
difficulties of advocating enterprise SSD adoption to users in who often had
high uncertainty about how their installations worked, uncertainty about their
future workloads and business directions coupled with doubts about vendor claims
- a new phenomenon in SSD pricing arose which bypassed ration justifications
altogether. I discsussed this in
