what were the big SSD, storage and memory architecture ideas which emerged
and became clearer in 2016?Here are some early incoming answers...
|"As 3D NAND gets designed
into all upcoming products we see everybody trying to manipulate and
characterize the flash at a low level in ways that they did not all need to do
before, partly because LDPC is required just to meet the specified endurance.
This is delaying roll-out for many because they either do not have the required
flash skills or they (other than our customers) do not have access to a tool for
automatically characterizing the flash and generating the LLR tables."|
Pearse Coyle, CEO - NVMdurance
|"SSD capacities exceeding
HDD capacities are now shipping in volume this year in the enterprise."|
Greg Wong, President -
|"The integration of the
PMEM/DAX driver into the Linux kernel allowing us to expose persistent memory as
a block device so it can tie into existing block and filesystem
And also the NVMe over Fabrics standard and OS
support. Allowing us to present NVMe over RDMA to enable a new level of
performance for remote block storage."
Senior Technical Director - Microsemi
|"Storage Class Memory...
As storage class memories are emerging, the memory hierarchy will be changed.
NOR-based NVDIMMs, such as 3D Super-NOR and 3D XPoint, will replace DRAM and SSD
at the same time. |
Also, software-based NVDIMM-P, such as HybriDIMM,
will come to the storage class memory market. Storage class memories mingles
fast-but-expensive volatile, and slow-but-inexpensive non-volatile memories
together. As a result, it will significantly boost system performance at low
cost and create huge market opportunities."
President & CEO - BeSang
|"The most significant
ideas we at Virtium see and are directing our resources toward center on taking
SSD security, reliability, durability, and manageability to a much higher level,
to meet the needs of increasingly connected industrial embedded environments.
These ideas are now being realized through drives self-encryption capabilities,
advanced remote-monitoring software, dramatically reduced power requirements,
and the development of SSDs specifically for the Industrial Internet of Things
VP Marketing, Virtium Solid State Storage
perspective, we are heavily invested in NVMe over Fabric (NVMf) technology for
which our NX-Series Storage Arrays are based. |
With the ratification
of the NVMf specification this past June, flash devices such as SSDs and storage
arrays can now communicate over RDMA networks (such as RoCE or InfiniBand),
delivering the same high performance, low latency benefits as local attached
Storage arrays based on NVMf, such as our award-winning NX6320,
avoid the lower level SCSI transport layer, which results in faster data
throughput and accelerated data access making NVMf solutions ideal for
compute-intensive HPC and database applications."
Director of MarComms - Mangstor
|"I think definitely it is
NVMe. We have seen the demand has increased unbelievably this year. Most
customers told us that NVMe were their first choice of new systems design since
it combines ruggedness of traditional SATA and the high speed of PCIe."|
Manager at a rugged SSD company
|"Nvme and soon 3D Xpoint
are affordable, solve low queue depth and write performance issues and will make
performance claims from the usual suspects irrelevant... Removing the interface
bottleneck was the giant step here."|
Meijers, System Engineer at Greenpower (Pharmaceuticals)
|"From our experience in
2016 we have seen 2 major things. |
First is the combination of storage
with the hypervisor (like our eEVOS). Without which customers would need to use
2 suppliers (storage and hypervisor) which would make support a nightmare
The other is NV-DIMM techology, we have customers and
partners implementing it with our product. It provides best of both worlds - RAM
speed with extreme I/O and data still remains in case of server crash."
CEO at euroNAS GmbH
|"For Hyperstone, the
biggest idea and industry trend that we pushed and participated in is the
implementation of page-based-FTL running on DRAM-less controller architectures.
This approach improves random write performance, increases endurance while
maintaining power-fail robustness at the same time. As this architecture also
reduces system cost it is also adopted in consumer markets.
We also see a significant adoption of USB 3.0 in industrial/embedded
markets. Certainly, the most hyped topics, at the FMS for instance, were 3D
NAND and NVMe but for both we do not yet see any sufficiently mature products or
any massive adoption in our markets"

what were the big SSD, storage and memory architecture ideas which emerged

|In popular fiction about time travel
it has often been said that the paradox you want to seriously avoid is meeting
yourself coming forwards while you are actually traveling back.|
writing about the computer market this is something which happens to me a lot -
as I look back on detailed technology and market predictions from the past and
compare them to what happened. There's nothing too mysterious about this
swinging back and forth in content time. It's just something which happens
when I randomly dip into past pages I've written on the web over 2 decades to
remind myself - what was all that about?
One of those prediction
paradoxes occurred recently in connection with an SSD news story in
August 2016 -
which intersected with a prediction article published in 2010 - which I had
illustrated at the time with this spoof press release.
|Stealth mode startup wakes
petabyte SSD appliance market
Editor:- October 17, 2016 - Exabyte SSD Appliance emerged from
stealth mode and today announced a $400 million series C funding round and
immediate availability of its new Paranoid S3B series - a 2U entry level Solid
State Backup appliance with 1PB (uncompressed) capacity. ...Latency is 10
microseconds (for accesses to awake blocks) and 20 milli-seconds (for data
accesses to blocks in sleep mode.) The scalable system can deliver 20PB of
uncompressed (and RAID protected) nearline storage in a 40U cabinet - which can
be realistically compressed to emulate 100PB of rotating hard disk storage using
less than 5kW of electric power.
|Although some of the detailed
flash memory predictions
in that article 6 years ago were embarrassingly pessimistic compared to what we
expect to be seeing in the near term future - the purpose of that article -
this way to the
petabyte SSD - was to explore the user value propositions which would enable
solid state storage to become an attractive proposition to buy for high capacity
enterprise storage even if hard drive capacity cost less per physical bit. And
to make my point I used the extreme
condition that even if magnetic storage drives cost nothing to buy - they
would still be displaced by SSD based storage in cost sensitive applications.|
arguments I used then are accepted as everyday reasons to buy such systems
nowadays - but I can confirm at the time of publication they fired the
imaginations of many movers and shakers in the market.
Since 2010 as
I've written various stories about various SSD systems companies I have from
time to time wondered which company is going to show such products first.
Several years ago I thought a hot contender was
Skyera. But a few
weeks ago on a booth at FMS -
Nimbus Data was showing
boxes which looked very similar to this concept. Although the Nimbus boxes are
much faster than I predicted - because SSD power management has evolved to be
much faster at cold boot than the good-enough examples I used in my old article.
A critical ingredient of the spoof story and today's reality is
petabyte SSD was (I thought in 2010) an elegant wrap up and last bullet point in
a set of predicted
user value propositions for SSDs which I had been writing about since 2003.
Upto that point (in 2010) my technology predictions had been pretty reliable at
anticipating disruptive changes many years before any such products or companies
made them happen. But the set of user value propositions wasn't as complete as I
thought. And the market experience of virtualizing storage and memory and
leveraging ideas from the early adopters in the enterprise
PCIe SSD market -
uncovered yet another big gap - tiered memory - and trading latency for density
by adding more layers and a new core construct of persistent memory (with fast
memory boot which doesn't rely on preloading from magnetic storage). This
has been playing out in the SSDs news pages in the past 2 -3 years but
still has a ways
to go yet.
Which reminds me of the tentative title of this blog
today (It really is today. I got up and started typing these words at about 4.30
It is traditional at this time of the year for me to start
collecting together and reflecting on the big SSD ideas of the year.
can see recent examples of these "big ideas" or annual round up
blogs for various years here:-
This list could have been longer. I'm sorry to say these retrospective
articles of mine about the enterprise market - which recycle old news to create
new historical content - started in
1996 (and look
even further back - to the 1980s.
So... in a long overdue break with
tradition I'm going to change the format for my upcoming big SSD ideas of 2016
During the next few months I'll be asking some of you
to tell me what they think are the important ideas in their SSD related work in
2016. And I'll add the most interesting comments to a much longer versions of
