this month when I interviewed
the company's CEO - Holly Frost the thought of what TMS might be
worth had crossed my mind. That's one of the legacies of the

Here are some wider scoped articles which I've
previously written on this theme.
- Clarifying SSD
Pricing - where does all the money go? Includes indicative price data
for different types of SSD - including enterprise SSDs.
Enterprise storage is more about the value of
doing things with data. Consumer storage is more about the color and the shape
of the box..
- And in my roadmap
to the Petabyte SSD article - I explained why even if HDDs are given away
free - they will be uneconomic compared to
SSDs in the datacenter of
the future. Storage is about more than just raw capacity. It's the ability to
do useful things with data in a timely fashion in a physical space which you
can sustainably afford.
How Fusion-io changed the SSD market

SandForce enables enterprise oems to tweak the flash capacity
Editor:- December 12, 2011 -SandForce today
it is sampling a new SSD controller - the SF-2481 - which provides increased
data security and
features compared to earlier models from the company.
comments:- the new SandForce controllers are aimed at enterprise bulk
storage applications / cloud
storage. Performance is about the same as before - and the encryption
strength is better - but the 2 main differences are:-
The over provisioning feature is a key parameter which
directly impacts the competitiveness of the oems who deploy SSDs with SF
controllers - who can now decide for themselves how they want to adjust the
flash in their systems between reliability - coping for
high IOPS -
or cost effectiveness in lower IOPS systems - where the SSD is being used in a
large storage array to
replace HDD storage.
- New improved media health test
Previous models of SF controllers hard coded this
parameter - which meant that arrays of (small architecture) SF inside SSDs were
uncompetitive compared to
SSD systems from Violin
you're selling a controller which can go into such a diverse range of apps -
it's impossible for the controller designer to choose a single set up which is
best for all apps. Fusion-io
has always enabled its oem partners to tweak this paramater in its PCIe SSDs. My
headline comes from the article

Editor's comments:- I've
been talking to TMS every month for over 10 years - and I've been writing
about their memory appliances since the early 1990s - so you might think that I
would have run out of things to say by now. When I saw the preliminary specs
for the new RS-720 - the features which jumped out at me were:-
- the low R/W latency for this class of SPOF product. Which is 2x as
good as the next fastest product I know - the 6000 series fron
Violin - and several
times faster than some other tier 1 SSD vendors such as
A few days ago I spoke to
President of Texas Memory Systems about their new SSD, what they think about
what's going on in the SSD market, and the philosophy that steers the design
of their SSDs. In a hour long discussion I learned enough new stuff to write
several new articles. So instead of condensing it down here into a couple of
bullet points - I'm going to give you the benefit of what I learned in a

and close to the usable RAIDed capacity that a
Fusion-io 1U server

validates what they are doing (and shipping) already - and that the enterprise
SSD market is big enough for all vendors in this category to

- SSD cache - the automatic kind
- SSD acceleration As Soon As Possible
- Auto-tuning SSD Accelerated Pools of storage

The word "new" in the title is deliberate. It
replaces an article I wrote about SSD ASAPs when the market started in 2009.
Since then - my thinking - and that of key players in the market has
developed. This should no longer just be regarded as a tactical market to bring
the advantages of SSD acceleration to legacy hard drive arrays. ASAPs are an
essential interface between different levels of SSD storage. ...read the article
OCZ's revenue growth accelerated by enterprise SSDs
December 1, 2011 - OCZ
revenue for the past quarter (ended November 30) to be in the range $100
and $105 million - an increase of approximately 90% compared to the
year ago quarter.
"We expect to report record revenue in Q3'12,
driven primarily by increased traction for our enterprise and server SSD
offerings along with initial shipments of our new PCIe-based offerings,"
said Ryan Petersen, CEO of OCZ Technology. "Based on the exit
bookings rates from November, interest in these products is exceeding our
expectations, due to accelerated adoption of our SSDs by server OEMs and
enterprise customers," added Petersen.
