how fast can your SSD run backwards?

today published a new article which looks at the
11 key symmetries in
Whether you're a
investor in SSDs -
this new conceptual framework will help you to comparatively evaluate any SSD
compared to competitive offerings. It's helpful whether you're looking at raw
SSD IP and controller chips right up to the most complex
SSDs are complex devices and there's a lot of mysterious
behavior which isn't fully revealed by
vendor's product datasheets and whitepapers. Underlying all the important
aspects of SSD behavior are asymmetries which arise from the intrinsic
technologies and architecture inside the SSD.
Which symmetries are
most important in an SSD? - That depends on your application. But knowing
that these symmetries exist, what they are, and judging how your selected SSD
compares will give you new insights into SSD
no such thing as - the perfect SSD - existing in the market today - but
the SSD symmetry list helps you to understand where any SSD in any memory
technology stands relative to the ideal. And it explains why deviations from the
ideal can matter.
The new article unifies all SSD architectures and
technologies in a simple to understand way. Now that I've spent
20 years thinking about
it - it all seems really obvious now. This is the most important article
about SSDs that I've written in the past few years. I couldn't have written
it before. I hope you like it.

PS - I'll be using the new symmetry terminology
from now on in news stories and in SSD company profiles - so you'll soon get
used to it - just as you've got used to lots of other
Intel buys InfiniBand line from QLogic
January 24, 2012 - Intel
an agreement to acquire the
40Gbps (pdf) related product lines, IP and business assets of QLogic.
comments:- if you're not familiar with
InfiniBand - it was
originally proposed in 2000 as a standard for remote CPU R/W with small packet
sizes and ultra low latency to support arrays of CPUs over many cards and racks.
In the early days - InfiniBand evangelists and some storage analysts believed
the standard would go into the commercial server mainstream.
what happened was that fatter multi-core CPU chips, and faster GbE wiped out
the volume market need for IB technology - because they could do the same job
cheaper and incrementally for smaller clusters of CPUs. So the IB market
nowadays is mainly a niche market for scientific research and high performance
Some of the
fastest SSD benchmarks
have been recorded in IB environments. And at one time (before 2008) I thought
that IB might be a significant and natural upward path for high performance
SSDs. However, PCIe SSD
systems also support remote array connections - so IB's role remains that of
occupying the narrow turf of clustering hundreds to thousands more CPUs than
Intel or others can pack into a single chip.
Another way to think about
it is this. You can't have viable HPC without SSD. But you can have a healthy
SSD market where HPC is a small niche.
There's no doubt that SSDs are
an enabling technology which make it realistic for CPU designers to think
about what they could do with hundreds of cores on a single chip and over 1,000
cores on a single server card. I discussed that blue sky concept with
processor designers nearly 10 years ago. But does the mainstream market need
data driven factories of the future - the answer is yes. But that could be
another 5 years in the future - because there are still closely related
standards to firm up - such as Hybrid
Memory Cubes. And
shows that new standards
take years to get into the market. In the meantime - if you're not in the HPC
market - but still need very fast CPU performance - keep an eye on what the
leading PCIe SSD makers do - and you won't go far wrong.

Kove launches 20 Gigabytes/s RAM SSD
November 22, 2010 -

terabyte class RAM SSD
product line (with under 25 µS latency) called
Xpress Disk - which can sustain
20GB/s throughput via 6x InfiniBand ports and 600,000 read IOPS and 500,000
Editor's comments:- despite costing an order of
magnitude more - the market for
RAM SSDs hasn't been
killed by flash.
On the contrary - all the vendors of high end RAM SSDs that I've
spoken to in the past year say they have been pleasantly suprised to see demand
for this type of product growing. The reason? - When a bunch of flash SSD
accelerated servers hits a storage performance bottleneck - the only way to go
faster is to interpose RAM SSDs. And unlike
the old days
when the first terabyte RAM SSDs became commercially available (2003) - users
today are already amenable to the concept of SSD acceleration.

Fusion-io SSDs deployed in nuclear safety program
June 15, 2010 - today it was
that Lawrence Livermore National Laboratory
has deployed over 100TB of Fusion-io's dual
320GB enterprise MLC ioMemory modules deployed in ioSAN carrier cards that
connect over Infiniband
in a testbed
project to develop high-performance simulation computing capabilities
needed to ensure the safety, security and reliability of the nation's aging
nuclear deterrent without underground testing.
With the addition of Fusion-Powered I/O, the Hyperion testbed will
deliver over 40 million IOPS and 320GB/s of bandwidth from just 80 1U
appliances (2 racks) compared to 43 racks and more power if implemented in an
HDD based system.
"This project demonstrates how flash that performs like memory, rather than
disk, can scale to the highest levels of performance," said Neil Carson,
CTO of Fusion-io. "Equally important, it demonstrates that it is possible
to accomplish this with a fraction of the infrastructure. Our customers are
already capitalizing on the ioMemory's ability to let them do far more with far
less, and Lawrence Livermore has just taken it to the next level."

"The IT community is looking for ways to increase
storage efficiency while boosting productivity," said Greg Schulz, founding
analyst at StorageIO

other bottlenecks and start enabling storage efficiency via performance
optimised storage that does more work, in a smaller footprint (power, cooling,
floor-space, economic) while boosting productivity. Anyone can attach
flash SSD to a
computer or storage system; however the real trick and business benefit is when
a storage system or applications server can fully utilise the technology without
introduction of, or moving I/O and performance bottlenecks elsewhere. The
RamSan-620 is an example of a new breed of storage solutions that have been
optimised to leverage the capabilities of flash SSD while preserving application
QoS and service level objectives."
there has been a lot of debate in the
fastest lanes of
the SSD accelerator market about whether it's better for users to deploy this
technology inside the server box (as
PCIe cards) - or
outside the box (on the SAN).
This is reminiscent of the old
vs RISC processor debates of the mid 1980s.
Entertaining as it is
to analyze these polarized approaches I explained in my
2009 - Year of SSD
Market Confusion and
articles why I believe that users will, in fact, do both.
Systems has in the past told me, that whenever they launch a new rackmount SSD
they have some customers who just fill up a complete cabinet with the new model
and use that as their basic unit of solid state storage until the next new
model comes around. They'll only need 6.5kW for the 100TB SSD enabled by
this model - and they'll get the transactional performance of 10,000

standards-based, memory-speed protocol over either 10GigE or 40GBps QDR
ioSAN shares ioMemory capacity between servers. With latencies of less than 2
microseconds, the ioSAN incorporates an integrated network interface that can
dynamically alternate between 10Gb/s Ethernet or 40Gb/s quad data rate
InfiniBand. The built-in network interface makes it easy to create networked
storage across servers with increased performance and flexibility, and with zero
footprint. This networked storage is extremely easy to integrate and manage
within existing server infrastructure. Prior to general availability of the
ioSAN, Fusion-io is inviting innovative and visionary companies to join them as
they launch their 3rd party development program at the beginning of next year.
this development, everything you thought you knew about
storage networking is no
longer true," said David Flynn, CTO of Fusion-io. "The ioSAN fuses SSD
with storage networking, combining the best of direct-attached and storage
networking with the best of SSD and traditional storage. With this revolutionary
advancement, Fusion-io has commoditized high-performance network storage in the
same way that companies like NVIDIA and ATI commoditized high-performance
graphics processing. Fantastic applications of this technology are now beginning
comments:- Fusion-io's full press release text says this is "the
world's first networked enterprise SSD."

correct because fiber-channel

Texas Memory Systems
What is special about Fusion-io's new product is that
it could become the first high performance native NAS SSD to cross the chasm
between PR-ware and success in the market. Although high speed NAS SSDs have
been announced before on these storage news pages by various companies in years
gone by none of them left a deep impression in the market. The reason? - the
benefits of SSD acceleration were not cost effective when channeled through
slow ethernet networks. The low cost of Fusion-io's flash array coupled with
its high speed and 10GbE interface could place this product in new
territory in the SSD roadmap.
