Editor:- January 6, 2012 - in a historic
yesterday showing the capabilities of its latency reducing Auto Commit
Memory (ACM) extension Fusion-io
announced it had exceeded 1 billion IOPS (64 byte data packets) in a
configuration which used 8 HP servers each configured with 8x
ioDrive2 Duo PCIe
Steve Wozniak, Fusion-io's Chief Scientist said - "...As
an engineer, what really excites me about extensions to our core technology such
as ACM are the possibilities introduced when flash is utilized as a new memory
tier. Instead of treating flash like storage, where data passes through all of
the OS kernel subsystems that were built and optimized for traditional storage,
our core ioMemory technology offers a platform with new programming
primitives that can provide system and application developers direct access
to non-volatile memory."
David Flynn, Fusion-io Chairman
and CEO said. "This breakthrough is not something that could be
achieved with hardware alone. Intelligent software that optimizes NAND flash
as a low latency, high-capacity, non-volatile memory solution for enterprise
servers can transform the way organizations process the immense amounts of data
that powers our lives today."
Editor's comments:- although
we're used to thinking about SSD IOPS in terms of bigger packets - such as 4kB -
instead of the very small packet size in this demo -
IOPS is simply
a convenient and not always reliable way of comparing the relative
performance of storage products.
In real life - users don't have a
choice of what size the R/W operations are which take place in their apps. They
occur at all sizes (mostly smaller than 4kB) and when these R/W operations take
place in traditional storage architecture systems - which internally impose
their own restrictions on the minimum size of atomic data packets - that's where
latencies and performance become discontinuous compared to the value of the data
update due to amplification
and packetization effects.
In my view - the important thing about this
demo - is that the same PCIe SSD product which can perform useful work as a
storage device - can also be deployed as a super scaler memory device - when it
is running the appropriate software.
The difference is that with
traditional storage software - you might expect that a 64x PCIe SSD system might
hit 64M IOPS or some similar figure (regardless of the small size of the data
packet). Instead the demo shows that apps developers can get 16x more
performance in small R/W transactions if they are willing to invest the
effort to make their apps work with FIO's new APIs.
It's that order of
magnitude difference which is the attraction for some markets - because it
closes the gap in performance between
RAM SSDs and flash
SSDs. And when you can run apps 10x faster than other flash competitors at the
same price - or support 10x bigger data sets than competitors using RAM SSDs -
that create new markets. See also:-

to establish a stronghold in this market with its own ASIC) at a potential
disadvantage as capacities scale up.
One of the design challenges for
LSI will be to see if they can extract the proven flash management features in
past SandForce controllers and scale them up to support bigger capacities and
faster throughput without adding latency penalties (which currently accrue with
arrays of SFPs) or which uses a new processor core or split controller
architecture to better support larger flash chip populations.
