year when many marketers are reviewing their business plans and wondering about
ways to increase their visibility to the people that matter in the SSD market.

I say "misperceptions"
advisedly because sometimes in the past - SSD vendors have been perceived to be

|A3CUBE - first US customer
Editor:- September 18, 2014 - earlier this week
imminent US customer shipments of its PCIe connected shared reflective memory
fabric - with the unveiling of the system software which works with its
previously announced RONNIEE Express platform.
Foundation software (overview pdf) is the new management and OS software
which enables application agnostic hardware based memory synchronization of
DRAM memory blocks across multiple servers (scalable to thousands) which are
connected via a PCIe fabric with worst case access times under 1 micro-second
(which includes operating system and software overhead). This enables access to
all the resources in the cluster as if they were local.
comments:- Before talking to Emilio Billi,
Founder - A3CUBE last week about the new Fortissimo - 3 ideas popped into my
- modeling the application performance
I realized that in
the absence of any other data (at this stage of the product's life cycle)- a
good predictive analog for the usability of this remote shared memory system
would be Diablo's memory
channel SSD architecture.
The key difference being that the 1st
generation MCS has typical latencies around 3 to 5 microseconds (compared to
800nS RONNIEE Express), and MCS is operating with flash - whereas RE operates
with DRAM. But as a first order approximation -my thinking was that any app
which works well with MCS in a local server - will work just as well - or better
- in a remote server connected by RE.
- the importance of strategic software standard support
guess is that for many smaller developers of large memory architecture systems
- SanDisk's ZetaScale
(and related) APIs will come to be regarded as a "safe" hardware
independent SSD software platform for flash. So - if it was easy to integrate
A3CUBE's Fortissimo / RE within such APIs - that would provide a gateway to a
much bigger market.
So I mentioned all those
things to Emilio when we spoke. And this is what I learned.
- beyond legacy storage and SSD fabrics
Obviously to get
business now - A3CUBE has to demonstrate that their products can be useful and
competitive when used with existing storage and SSD installations and
But as more of the installed base moves towards
(always intended to include SSDs at the outset), and in the next 5 to 10 years
as we see the current new generations of "software as something useful in
an SSD server" - give way to new
ecosystems - developed by stealth mode companies like
Primary Data -
whose products don't even exist yet (except as tantalizing
investment objects and
patent applications) - I could see that the A3CUBE style of connection - would
still fit in well - because the ability to replicate and synchronize
remote memory in multiple servers at latencies which are closer to hardware than
software - isn't going to go oyt of fashion.
- Emilio said Diablo was one of the first external companies to recognize the
work that A3CUBE was doing. And he said that Diablo's APIs should work
easily with A3CUBE's platform (just as many other memory intensive apps).
- as I speculated before our conversation - the ability to seamlessly converge
remote low latency RAM with remote flash across an almost unlimited set of
servers - is a mind boggling ecosystem enabler. Because we should now view SSD
memory products which do useful things locally in a single server - as simply a
subset of a continuum which can span racks and cabinets - and change not only
cost dynamics - but the very determination of what type of apps are possible.
- Emilio said a significant bottleneck in all previous fabric systems was
the mechanism of metadata synchronization.
That's traditionally done
in software - and no matter how many hundreds or thousands of servers you have
in your installation - the scalability of those systems ultimately comes back to
the software mechanism of how fast 2 servers can replicate or share a set of
In A3CUBE's RE platform - the ability to broadcast an identical
content of shared memory across hundreds or thousands of connected nodes is
done in silicon.
- re reliability? - I put it to Emilio that everything was being staked on
the reliability of the RE platform - and I asked more about that.
said that the Fortissimo / RE system can be configured to drop back to an
ethernet fabric if the core RE fails - but if budget allows - then it can fall
back to another RE. In neither event do you lose data or access to data. A3CUBE
has been collecting reliability data from their early access systems - and will
publish more about that later.
- re when can customers order these systems?
Emilio said that the
first production system is already scheduled for delivery to a US customer next
So to my way of looking at it - the general availability
issue just seems to be related to how many of the software features are nice to
have versus essential. That will depend on what the applications are.
- re my other points - Emilio said that legacy big memory software platforms
are already supported by Fortissimo (see their site for more details) and we
found a lot to agree about re the other things I mentioned above.
Seagate announces strategic technology agreements with Baidu
September 17, 2014 - Seagate
it has signed a strategic cooperation agreement with Baidu,
China's largest web services firm.
Under the agreement, Baidu will give priority to Seagate products when
considering components for all Baidu servers and storage facilities. In return
Seagate will give priority to Baidu when providing enterprise storage products
and relevant support, as well as maintain a dedicated engineering team for
Editor's comments:- This is a very significant
business announcement for Seagate. But it shouldn't come as any surprise - as
the destinies of the companies were already set on a natural convergence of
interests course which only needed the missing part of the IP jigsaw (SSDs) to
complete the required harmony.
Here below is a verbatim quote from
my coverage of Seagate's acquisition of LSI's SSD business in
think that even if Seagate disregarded any new markets - and focused only on the
high volume potential of existing cloud infrastructure 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 segment of the cloud."

another auspicious design win for ULLtraDIMM
September 16, 2014 - SanDisk
that its ULLtraDIMM (memory channel SSD)
has been selected by Huawei
for use in its RH8100 V3 servers.
Huawei is ranked the top server
supplier for cloud and
mobility in China - by Sino-Bridge
Editor's comments:- Since the
announcement that IBM was
using ULLtraDIMM SSDs in some high end servers - there haven't been many
conspicuously auspicious design win announcements like today's Huawei story.
One reason is that IBM had a head start on the market - having worked
with Diablo for years to
refine the MCS architecture and software APIs.
Another reason is that
the 1st generation ULLtraDIMMs apparently guzzled more electrical power than
modern RAM DIMMs even
though they were still within the permitted power envelope according to industry
This means that in order to support arrays of them in a
server design (and indeed you do need arrays to get
performance beyond the PCIe SSD level) requires a redesign of the copper
power tracking on the motherboard. You can't just plug large numbers of
ULLtraDIMMs into any old server without analyzing the thermal consequences.

Samsung in volume production of 3D DDR4 RDIMMs
August 27, 2014 - Although the main interest in DDR4 RDIMMs - from an SSD
market perspective - will be in how that interface opportunity gets leveraged
channel flash SSDs - let's not forget that the motherboard slots - which
will enable that market - have been designed for
DRAM. So the DRAMs will
come first and are an important part of the countdown to the new DDR4 flash DIMM

celebrating "a new milestone in the history of memory technology" with
the announcement that the company is in volume production of the
industry's first 64GB DDR4
RDIMMs (DRAM) that use 3D "through silicon via" (TSV) stacked die

consumer SSD compression software seeks partners
August 26, 2014 - When it comes to the question of
cost per SSD terabyte
users in the enterprise market have many competing options for stretching
their SSD budgets and balancing cost and performance. And I have known of a
small number of companies doing similar things in the
consumer SSD market.
I was contacted by Simon King - the founder of a new (to me) company -
ZIPmagic Software (based in
Australia) which is offering its Windows compatible whole disk compression
technologies (which was originally developed for the HDD market) for licensing
to SSD oems.
Here's what Simon said.
My company has built a product for transparent disk compression.
Unlike traditional compression tools, transparent disk compression increases the
total storage capacity of a disk without requiring data to be decompressed
before it can be used by apps or users.
With the advent of fast but
expensive SSDs, fixed storage tablets, and (private virtual) servers which are
expensive to upgrade or relocate; there is a new market niche for disk
I have attached some product briefs on my company's disk compression
solutions. Our price point is competitive with traditional compression tools
such as WinZip. Our product also meets and exceeds the capabilities of
traditional compression tools across the board.
SSD manufacturers can
safely advertise double the disk capacity using our software-only solution, and
reduce their cost per gigabyte for their expensive products resulting in
a win-win scenario for both consumers and the manufacturers themselves. Our
software is very safe, secure, and scalable; based on Microsoft technologies,
but extending the capabilities of those technologies with our compression and

Diablo unveils DDR-4 flash DIMM SSDs
7, 2014 - Diablo
yesterday announced details of a new 2nd generation
SSD - low latency flash SSD accelerators in DDR-4 sockets - which will
sample to oems in the first half of 2015.
Along with the new hardware
technology there will be an improved software platform - with features like
NanoCommit - which Diable says will enable hundreds of millions of
transactions per second, with nanosecond latency.
Storage DDR4 solutions represent the next evolution of Server Acceleration
technology," said Riccardo
Badalone, CEO and Co-founder of Diablo Technologies. "In addition
to supporting a faster memory interface, the Carbon2 platform delivers
unprecedented levels of hardware acceleration for new software innovations like
NanoCommit. Converged Memory, where the best of Flash and DRAM are combined,
will rely on this type of technology to give applications the ability to
transparently persist updates to main memory."
