|Skyera launches industry changing enterprise
Editor:- August 14, 2012 - Skyera today
launched its first product - a 1U half-depth 10GbE
SSD rack with 44TB usable capacity ($131,000 approx), 3.6GB/s throughput and
upto 1 million IOPS using under 800W electrical power.
software includes inline dedupe, compression, snapshots, clones and various
Skyera will demostrated the new
Skyhawk next week at the
Flash Memory Summit.
comments:- last week I spoke to Skyera's founder and CEO Rado Danilak
and some key people in his team - which in addition to core members of the team
who designed some of the early
SandForce controllers -
also includes talented and experienced
people from other well
known chip and enterprise storage companies.
Skyera make a big thing
about their cost value proposition.
They deliver fast SSD storage
at a system list price under $3 / GB (uncompressed) and about $1 / GB (with
compression and dedupe). That not only beats best of breed SSD systems but
seriously challenges HDD based storage too.
Designed from the ground
up the Skyhawk can be summarized as using
controller architecture (proprietary rather
than an array of COTS open SSDs) and with an integrated
software stack which
screws the efficiency of
as tight as can be - by intervening at multiple levels (high
intelligence flow symmetry.)
In any given year in the SSD market
there are maybe 2 or 3 industry changing announcements - which illustrate what
the shape of the future could be.
Skyera's Skyhawk is one of those
in the year we're already in. And would be just as significant if the launch
had been delayed into next year too.
Here's some more stuff I learned
from talking to Skyera.
Rado said Skyera has
one strategic investor - which he didn't want to name right now. The company is
mostly owned by its management. That gives them an incentive to design a product
which can make money as soon as possible.
FPGA rather than ASIC -
for Skyera's hardware controller
The FPGA versus ASIC tradeoff
debate in electronic design goes back to the mid 1980s. With FPGA you buy a
chip that's got arrays of logic and common functions already in it. You
define what your FPGA does by programming the interconnections in a way
that's similar to writing to flash. With ASIC you have almost total freedom to
decide what functions your chip does - but the chips are made in a factory
that's making a lot of other chips - not just yours. You're buying time in
someone else's multi-billion dollar factory. There are set up fees, learning
curves and queues involved.
Skyera implements its controller using
That gives flexbility (also
explained to me as
a factor by Holly Frost at competitor
Texas Memory Systems
- which uses both ASICs and FPGAs in different places - while
Nimbus prefers to use
exclusively its own ASICs and
Fusion-io is still
staying mostly with FPGA.
In a rack system - the recurring unit cost
is not a big deal - whereas it is a
in a single small drive - which is why
STEC made much of
switching to ASICs in its enterprise SSDs last year. Where the VC factor comes
back into the equation is that each design costs hundreds of thousands of
dollars - and months of delay. So if you have the realistic choice of either
FPGA or ASIC in the form factor and power budget - which is not an option if
you're designing a 1 inch
embedded SSD for example - then the FPGA route means you can ship products
sooner with less initial outlay and your revenue stream can contribute to
earning profits faster.
Having said that - my guess is that after
their launch - if Skyera said they needed another $500 million or so to do
something - like remodel the executive car park - VCs would rush in to supply
the cars too. But Skyera probably doesn't need that much money.
On the SSD architecture side I've already written
about the strategic importance of large architecture, adaptive DSP, SSD
between flash capacity and reliability and performance and the benefits of
integrating them at a high level. So I won't repeat those points here.
said he wanted to get the best performance and reliability possible out of "cheap
crappy flash". He said if you use a traditional
RAID 6 array - then the
latencies start to mount up - and you end up doing 3 writes cycles to get the
parity protection. That's bad for endurance and bad for latency too. He said
that Skyera's way of doing RAID-like protection means that the write
amplification for a 4kB write is an average of only a factor of x1.04.
That's a 3x reduction on write amplification compared to arrays of
2.5" SSDs for
example. There are many different levels in the hardware and software - where
the self knowledge about the system is used to good advantage.
controller technology can be adapted to work with any flash. In theory they
could populate production systems with the cheapest flash they can get and
even mix up the sources in the same SSD and still get a working system.
Nevertheless the company's deep knowledge of flash - means that (in my words)
there's little risk of cooking the memory cells to get the performance. And they
know which suppliers are better.
Earlier this year
to me how using adaptive DSP meant that you could get 60% faster write
performance out of MLC flash because the DSP gave you the data integrity when
using shorter write pulses and lower energy - which also leads to better
Anyway Rado explained - that once they
decided that they had to design a proprietary memory array - they knew they
also had to invest in the software layers to make it work within the enterprise
Internally their box is like an array of memory
connected to a switch. In that respect - it's similar to the RamSan systems from
Skyera's initial system isn't a
availability SSD - and although it has many essential enterprise features -
this will limit the appeal of the product in some applications. Nevertheless, I
know that many super users of SSDs would prefer to use their own cloud like
wraparound software - and all they need is a low cost scalable rack which they
can use as a component to build multi-petabyte SSDs.
Skyera said they
see traditional enterprise SSD apps like analytics being a good fit for the
HA is in the product roadmap and has hooks in the system
architecture. It will come later.
suggested to Skyera - that given how
company had been with SSD readers while they were still in stealth mode - the
problem they might have after this product launch would be too many inquiries.
That would place a burden on marketing to filter out the type of SSD leads
which were a good fit and those which were just curiosity.
Maybe we can
recycle the leads we don't want and sell them to other SSD companies - said
The SSD market will be watching Skyera with interest to see
if stacking all these new technologies together for the first time in a
system really works.
OWC has new SSD upgrade for Mac market

SSD cliff coming to memory makers sooner than to HDD oems -
that's why they're tired of waiting
Editor:- August 14, 2012 -
Outside of SSDs there is no viable long term future for mass memory makers.
Years ago when I first started writing about that concept - what I had
in mind was that SSDs would eventually become a more important market for high
volume memory makers than supplying components as boot devices and traditional
computer motherboard memory - because the memory capacity populating SSDs
would become orders of magnitude higher than anything which the memory makers
had ever seen before in traditional design slots. Also the profit - if there was
to be any - would be inside the application dependent SSD - rather than outside
the SSD party looking in as a merchant memory supplier to SSD companies.
those days the SSD market was about 100x smaller in revenue than the
memory market - so I knew the market transformation would take time - and it
would be easier for smaller memory companies to transform into SSD focused
What has only become clear in recent years - is that
there's another acceleration factor at work in the memory to SSD business
It's that next generation small geometry
flash memories (of the
type which could compete in mass markets) don't work
standalone components and in order to be used by anyone they have to be
wrapped around with some kind of complex
technology. Even if you don't care about whether
hard drives have a
future or not - the SSD cliff is coming to semicos sooner than that. If you're a
volume memory chipmaker - you don't have a future without SSDs in a time window
which is quarters rather than years.
Investors get nervous when they
read about that kind of thing - and particularly if they discover that the
memory market has to re-engineer itself into some kind of solid state storage -
much sooner than the message they were getting from the hard drive companies.
That's the reason you're starting to see SSDs starting to get
prominent mentions in the financial presentations done by memory companies.
One recent example - from Micron -
Flash-based Storage Vision (pdf) - tells you how they see the SSD market and
their position in it.
Don't get too attached to the exact numbers in
this document. The presentation under-sizes the
enterprise market in
my view. But it shows that the SSD market is getting serious attention at a
higher level and in wider circles than ever before.

FIO's results and various SSD market success factors
August 10, 2012 -
revenue - in the recent quarter (ended June 30) - grew 49% year on
year to pass $106 million, while revenue in FIO's fiscal year was $359
million (82% up on the year before) - the company
Editor's comments:- a lot of people ask me -
what's the secret of Fusion-io's success?
I've tried to answer that
question from many different angles - and you can see what I've said (on the
on this site search link.
My working life in recent years has been
spent exclusively focused on SSD companies.
Talking to them, reading
about them, discussing their technologies, business plans, experiences etc. And,
I have - as you can see in the
SSD Buyers Guide
- offered a variety of lists which you can rationally populate with the names
of SSD companies by analytical measures which everyone would agree with.
there's another list too- which I have in my head - which I've never
written down, or published - and which is just based on pure gut feel and
I can place almost any enterprise SSD company into 1 of 2
You might ask - Why don't I publish it?
- those who get the SSD market - and where it's going
enterprise SSD Goldrush
you don't have to understand where the
enterprise SSD market is
going. You can still get very good business results and satisfied
customers by incremental and tactical advances in products (if you're a
vendor) and projects (if you're a user).
My list of "who gets
the SSD market" - works for me. But it might not be so useful for you.
there are better shortcuts which don't involve such subjective judgements
(on which not everyone
would agree anyway) and which don't require any detailed knowledge of what
motivates the thinking inside these companies. Because - and here's a sanity
check - it's always the market which is the final arbiter of success.
That's why (and I can't say this too often) looking at lists like
the Top SSD Companies
is useful. It tells you which companies other people like you (who think
seriously about the SSDs) are giving more of their attention to. I don't rank
these companies. You do.
So it doesn't really matter what I think - at
a gut feel level. Except when it comes to me deciding where I should be
spending more of my time:- such as - which emails should I reply to? which
phone calls should I take? and for how long? and which web pages should I
see? Trying to convert this chaos into a coherent narrative - which might be
useful - is the fun part and it pays for the cheese.
Beware of easy
answers and succcess formulas in the SSD market. Few of them can stand the
test of time. (Even mine.)
With the possible exception of this one.

STEC's marketing legacy still imploding revenue
August 8, 2012 -
in the recent quarter was halved compared to the year ago period, and is 19%
lower than the immediately preceding quarter - it was
yesterday - and the company has set aside $35 million (approx) as a
contingency to settle claims connected with share activities in 2009."
many years I strongly criticized the company's marketing in these pages for its
weaknesses in routes to market and tardiness in extending its technology into
the enterprise PCIe SSD
Recently (June 18) I said I
was pleased to see many signs that the company has made visible changes and
improvements in its marketing. But years of neglect won't be cancelled out in 1
month or 1 quarter - and that's why this quarter's revenue trajectory
still looks so dire in comparison to competitors like
OCZ (54% SSD revenue
growth) and Fusion-io
(anticipated tomorrow - proved to be 49%).
STEC's CEO and Chairman,
Manouch Moshayedi said in the company's release text - ""Less
than a year ago, we began the strategic process to fundamentally shift our
business model from addressing the SSD market solely through traditional OEMs to

sees this type of SSD as heading towards a distinctly different storage tier -
and that's the direction of their software focus - even though in the present
market the products have been designed so they can drop in and work with
software and VMs with minimum fuss.
From the design and marketing
positioning point of view Virident has always placed great emphasis on
symmetry and scalability
symmetry. Shiva told me their performance scales linearly. That means if
you have 8 PCIe slots and install upto 8 of the new FlashMAX modules - the
available application performance will be Nx what you would predict from the
single module results.
Virident also say that their performance doesn't
degrade significantly over the lifetime of the product. They call this "Infrastructure
Predictability" - and say it's on the order of 1%. In contrast - the
performance drop off in some competing enterprise flash SSDs can be more like
20% to 30%. (This is a vulnerability in some flash SSD designs which has also
been mentioned by STEC -
as an argument in favor of their
asked Shiva if Virident uses
ECC techniques in its SSDs - and (as I expected) he said "no"

Nimble expands on scalability
Editor:- August 6, 2012
- "Scalability" - in SSDs and storage - means different things to
different people - and this is one of the themes discussed in my
So I was curious to see what Nimble Storage meant by
the word "scale" - as it's used more than 30 times in a
release from the company about a new range of rackmount SSD ASAPs.

Suresh Vasudevan yesterday gives a more precise explanation of what
they mean - which is in effect - you can scale capacity by adding hard drives or
scale performance by adding SSDs - or do a bit of both - "without ever
Nimble's systems span a much narrower
range of performance scalability than you would see across the
- so I'm not sure if scalability is the word I would have chosen to describe
what they do. "Flexibility and convenient management within a useful

Fusion-io does a few new things
Editor:- August 2,
2012 - the performance and strategic importance of
SSD software was
reinforced in 2 recent announcements by Fusion-io.
its new ION software
- which is a toolkit for bulding your own network compatible
SSD rack by
adding some Fusion-io SSD cards and their new software to any leading server.
The concept isn't entirely new - because oems have been doing this
with various different brands of
PCIe SSDs for years
and this is a well
established alternative market segment for PCIe SSDs. What is new - is
that it makes the whole thing much easier.
Fusion-io says this new
software product "delivers breakthrough performance over
iSCSI using standard
protocols." (1 million random IOPs (4kB), 6GB/s throughput and 60
microseconds latency in a 1U rack.)
Earlier this week FIO
it was collaborating on getting interoperability in server-side flash and
with NetApp. It's
easier now to write a list of major storage systems oems who aren't doing
something significant with FIO.
Going back to SSD software...
Microsystems created and leveraged the phrase -
Network is the Computer.
I have long thought an apt
reinterpretation of that in this decade is "the SSD is the computer"
- or maybe the "SSD software is the computer" - because the ultimate
characteristics of fast computers are determined more by the SSD architecture
which is installed - than by the same old CPU chips.
