|Seagate to acquire LSI's
flash business for $450 million |
Editor:- May 29, 2014 - Seagate today
it will acquire the assets of LSI's Accelerated
Solutions Division and Flash Components Division from Avago Technologies for
$450 million in cash.
The transaction is expected to close in the 3rd quarter of calendar
year 2014, subject to regulatory approval.
Seagate has for a long time appeared to be a bystander rather than a
cheerleader in the SSD market.
By acquiring the
SSD controller technology
which is at the heart of a significant proportion of SSD designs in the industry
- and also the 2nd largest enterprise
PCIe SSD maker (by
volume) - Seagate will come to be regarded in a different way by SSD customers,
partners and competitors.
The cost of the acquisition - seems low
compared to many past
examples in recent market history.
LSI itself paid $370 million for
SandForce in October
2011 - and you might think that in all the years of market and product
development since then - and particularly with the controller product line
having been upgraded to being an SSD drives and module business too - the
combined business should have been worth more.
But it wasn't - and
Avago - which has owned LSI's business for a few short breaths of market time -
obviously must feel it is getting a good deal.
Possible reasons for the
low valuation of LSI's SSD business (in comparison to maybe what it might have
fetched a year or so ago are:-
- LSI was latecomer to the
controller market. So that meant many SSD companies which needed this new
type of flash management technology had already made other strategic plans for
their next generation flash management roadmaps before LSI began sampling the
SF3700 in November 2013.
- There are strong competitive offerings available now in every segment of
the SSD market - and in comparison to the past when a single controller product
could effectively be competitive in a wide variety of markets - that's no longer
- Software has
become an essential part of enterprise SSD offerings. Not only does it provide
essential compatibilities - but it can also add efficiencies, reliability and
LSI's enterprise software offerings were always weak
add-ons in my view - in comparison to competing products - and were tactical
sales demonstration tools rather than genuine hard core enterprise platforms.
a way none of those valuation theories matters - but in another way they do -
because understanding LSI's weaknesses as an SSD company stretched in too many
markets takes us neatly onto - what I think could be the real synergy between
Seagate and LSI's controller business.
- Rackmounts. To succeed in the traditional enterprise SSD market today -
enterprise SSD makers need to think like systems companies or become actual
systems companies. That's where
efficiencies come together with new architectures.
But I can't
think of a single leading SSD systems vendor today (unlike a few years ago)
who would now offer LSI's controllers as the flagship controllers in a new
high end array.
The reasons being that LSI was late to market with
adaptive R/W, late to market with
controller design, and doesn't have a scalable software platform.)
What's Seagate been
historically good at?
Making huge numbers of storage drives cheap and
What has the SandForce controller design been historically

embedded applications than any other SSD controller design.
that even if Seagate disregarded any new markets - and focused only on the
high volume potential of existing
customers and big web entities (like Google and Baidu) - who need value based
enterprise SSDs - but who are perfectly capable of designing their own software
and APIs and firmware tweaks - then Seagate could leverage the LSI SandForce
SSD roadmaps for the next several years as a business tool to establish it
as one of (several) leaders in the utility SSD
of the cloud.
LSI on its own wouldn't be able to make such vast
quantities of drives at commodity prices.
Seagate on its own didn't
have the SSD IP.
But the new Seagate (with SSD IP now in its core)
can leverage that IP with its production control skills to cement new price
thresholds for value enterprise SSDs.
hostage to the
fortunes of SSD - why big companies can't afford NOT to be in the SSD
Afterthoughts (Friday May 30)
PS - Some of
the factors dampening the valuation of LSI's flash business seemed so obvious
that I didn't mention them in any of the bullet points above. But it appears
that they weren't as obvious to everyone - so here they are if you're
- Competing with your own customers.
When LSI acquired SandForce -
that introduced a new dynamic for the outlook of the combined business -
because LSI-SandForce was from that point onwards competing with many of the
companies which had previously been customers of SandForce controllers.
triggered plans in some of the big customer (now competitor) SSD companies to
look for alternative technology roadmaps which would level the playing field in
a future when they would be competing - at a drive level - with the controller
architecture which they had helped to establish as a de facto industry
And it also created a more favorable climate for competing
SSD controller makers who had lost out before. Such as
All sounds boringly obvious business stuff doesn't it?
That's why I didn't include these add on notes in my original short version of
- How much are SSD companies worth?
Generally - SSD companies ain't
worth as much as they used to be.
Nearly all mainstream enterprise
SSD companies (who have been shipping products for a few years or more - as
opposed to stealthy startups) have seen their valuations dip in the past year -
due to investors realizing that the idea of any one company dominating any one
segment sustainably is an illusion (for now).
That's because the
barriers to entry from new vendors are still low (due to the existence of a
very sophisticated SSD IP and parts ecosystem).
This means that
startups using new technologies at low volumes can still deliver SSDs which
are significantly cheaper to make than legacy SSD technologies - even when those
legacy SSDs are being produced in much higher production volumes. (Legacy in
this context - means anything that's more than 12 to 24 months old.)
suspect that the industry wide downgrade of the value of SSD companies (which
we saw last year with companies like
OCZ etc - for various
different reasons) will change direction - when we start to see dramatic
changes in reported revenues and profitability.
How will that happen?
think it depends as much on creative leadership, vision and discipline in
business models as it does on technology.
Because you can still make
money if you sell the right kind of SSD to the right kind of customer for the
right kind of purpose. (Especially if they come back soon after to buy more.)
But you can still lose money by selling an SSD that's better than it needs to
And you can lose money if you over invest sales and marketing
resources by selling the right kind of SSD for the right kind of application to
a customer who won't need any more of your products for another few years
Another question which it's inevitable to ask - however - is
What will happen to the continuing supply of SandForce SSD
It's hard to imagine that Seagate would - from its own
self interest point of view - choose to continue supplying controllers to
such a diverse range of SSD companies indefinitely.
Users of these
controllers have been on notice that the supply outlook for these essential
chips might change ever since LSI acquired
But unlike LSI - whose main business was selling chips - Seagate's
business is selling drives - and Seagate's volume takeup of these chips (for
the reasons mentioned above) will be more than enough on its own to justify the
NRE costs - without having to sell them elsewhere.
So that may
trigger a greater sense of urgency for answers about this factor - from smaller
customers who haven't made alternative plans yet.
My guess is that if
the regulators look at this transaction - that may be one of the aspects they
will focus on - because the contiunuing supply of these controllers to smaller
SSD companies in niche markets would a good thing from the viewpoint of
competitive choice. (And it wouldn't be too onerous for Seagate to maintain
the supply for a time limited period - because Seagate's biggest SSD
competitors all have their own controllers anyway.)
added - June 4, 2014
I've been talking to a key contact in LSI's
flash business to ask if there was any official corporate statement they could
make to clarify the status of this question:- what will happen to the continuing
supply of LSI SandForce SSD controllers?
But I wasn't surprised to
learn that - despite best efforts - there is nothing more they can say about
this for now.
The reason I'm not surprised is because there are
significant external entities (regulators, customers, competitors) which could
have a bearing on the final decision and if indeed it goes ahead. So it's not
just a matter of whatever LSI and Seagate would like to do.

Kaminario guarantees amplified usable capacity
May 20, 2014 - When I saw yesterday that Kaminario would be
talking about a
cost of around
$2,000 per usable terabyte of SSD storage in its new 5th generation K2
today - my gut feel was - this price metric must be based on some kind of
amplified capacity figure - rather than the conventionally
raw storage capacity - because I know that Kaminario isn't in the
deep flash IP
controller business - and unless I've been asleep and missed something -
this kind of headline figure isn't coming from arrays of
So I asked the company about it - and was told that the "average
$2/GB usable cost includes data reduction with Kaminario's guaranteed effective
capacity offering (meaning they will provide customers with incremental free
hardware if their original capacity needs aren't met)."
I probed again - does it apply to channel sales and well as direct sales? - I
got confirmation that indeed it does.
I think this is very

concept which sounds good in a news headline - of the type we've seen from a
lot of other vendors in recent years - and instead becomes a guaranteed figure -
like endurance - which users can learn to trust.
If Kaminario can
stand behind its usable capacity amplification claims - then other vendors
should do the same - or stop talking about promises they're not confident
enough to stand behind.
And if some vendors say - we don't know the
workload - so how can we provide a guarantee?
I'd say - get to know

alternatives are offering over specified, over priced systems - which work - or

PMC blog discusses latency implications of DSP ECC IP in SSD
Editor:- May 15, 2014 -
in LDPC-based Next-Generation SSD Controllers is a new blog by Stephen Bates,
Technical Director, PMC
who says - "The variability of the LDPC decode time is a function of how
many iterations it takes to decode the data from the flash."
his article Stephen says that the minimum number of iterations is 1, typical
is 4 and maximum is 20.
To relate that to latency - he says assume for
sake of illustration that each iteration takes a microsecond.
comments:- you can see how those numbers can start to stack up and make
inroads into the design of fast

different generations of

"SATA inside" SanDisk's ULLtraDIMMs
May 8, 2014 - Today I learned some new details about the architecture in SanDisk's
SSDs by watching a video -
Architecture and Design Technology - which was recorded at the recent
Storage Field Day event
(April 25, 2014).
Inside each flash DIMM are 2x SATA CloudSpeed SSDs
which connect to the DDR3 interface via a Diablo designed bridge
chip which has something on the order of "megabytes" of buffer memory
That gives a much better basis for
performance limits of these devices.
And it confirms why you only
start to see noteworthy performance from them after installing 3, 4 or
- despite the "SATA inside" limited nature of this 1st generation
memory channel storage design - the performance - aggregated at a block level -
results in a usable write latency envelope which
IBM has verified to be in
latency category than most leading
- if you're thinking long term - and roadmaps - it's reasonable to assume that
if a 2nd or 3rd generation of MCS flash DIMM SSD could abandon the "SATA
inside" and use instead a
architecture flash controller with a native memory array optimized type of
bridge interface - then the gaps between what MCS can offer - compared to PCIe
latency - could widen.
By the way in this 52 minute video I also
learned 2 interesting details about
SanDisk's CloudSpeed SSDs
which I didn't know before:-

EMC acquires memory channel SSD in a box company DSSD
May 5, 2014 - EMC
has acquired a stealth mode rackmount SSD company - DSSD
- it was announced
Products based on the new DSSD architecture are expected to be
available in 2015.
Editor's comments:- an informative and
entertaining article about this can be seen on
sounds like the DSSD product will implement a large directly addressable (by
PCIe) memory space - based on a transparent
RAM cache flash
scheme and will offer latencies similar to
SSDs - but with the capacity difference being that you can pack more
capacity into a box than in a bunch of DDR3 DIMMs.
It hearkens back to
the original big shared memory in a box connected by PCIe of
Violin's first product
- the Violin 1010 Memory
Appliance - which was launched back in 2007.
Although that was
pure RAM - and
enterprise users in those days weren't as
educated as they
are today. That meant Violin had to go back and redesign the product to include
a fibre-channel front end -
to make it fit in with the market idea of what an enterprise SSD box should
really look like. And that product also came in at the tail end of the
RAM SSD market - in the
year before new flash
controller architectures enabled SSD makers (including Violin) to displace
low to mid range SSD boxes with pure flash.
And before Violin's product
- in 1994 - Texas Memory
Systems was shipping a product called the SAM-2000 (Shared Access Memory) -
which enabled a bunch of different computers (even with different OS and
internal busses) to share the same memory at low microsend latencies and bus
There's an argument for saying that Violin already offers
something similar now to what EMC hopes to ship next year - in the shape of
Flash Array (WFA). Except that the 1st generation WFA uses GbE as the server
clustering fabric. But my guess is that it would be easy for Violin to offer
other variations with lower internal latency - to connect the CPUs to its
- if they thought enough customers would buy it.
IBM can already do
something similar (to Violin) with its X6 architecture.
limitations in IBM's technology are that the 1st generation of eXFlash DIMMs
(designed by SanDisk
and Diablo) are greedy
when it comes to power consumption. That means legacy server motherboards
don't have enough current capacity routed to the DIMMs to enable you to fill
them all with these modules. That's easy to change, however by adding more
copper in the motherboards and increasing the air flow in the box.
EMC offers the DSSD as a product which is unbundled from the brand of server -
then it might find a niche market for it.
But there are so many
different ways of tackling the same problem (such as enabling
PCIe SSD fabric from
storage, not to mention what's the PCIe interface for in
Skyera's new box)
that it may already be a crowded market by the time EMC has anything to ship.
Are you ready to
rethink enterprise RAM?

weird to see it's got a SATA bridge inside. And it consumes way more power
than most standard DIMMs. But despite those factors (due to the speed of
