comments:- Earlier this year I published a couple of reports and mentions
about SSD suppliers (LSI
and Memblaze) who
have modifed their controller firmware to eliminate or bypass functions from the
lowest level SSD drive - for large customers like Baidu - who then use their
array level software to get better utilization and performance.
market InnoDisk - uses
what it calls 3rd generation architecture - to partition intelligent data
actions between the controller and software stack.
Until recently -
only Fusion-io (in
whose products the flash controller and apps server - share the same CPU cores)
has been able to maximize high end context intelligence with low level flash
block data access at a similar latency level.
But once you've solved
the problem of making SSDs reliable and fast - it's tempting to create an SSD
instruction set which which focuses on application layer needs too - and not
just those of dumb storage.

LSI integrates "SSD market on a chip"
November 18, 2013 - LSI
its 3rd generation SandForce SSD controller family - the SF3700 which - based
around a single chip design - spans a wide spectrum of SSD market
applications (from consumer to enterprise) - includes native jumper-selectable
SATA or gen 2 PCIe interfaces - and incorporates adaptive R/W DSP ECC
Editor's comments:- The SF3700 (now sampling) is
the most ambitious design of a single chip
SSD controller in
Its 14 core design integrates many impressive design and
architectural features including:-
- the ability to efficiently configure as either
architecture or big architecture SSD controller.
design can be configured with as little as 3 flash chips in entry level
consumer SSDs - or as many as 129 chips when maximally configured in a 9 channel
enterprise design which can recover from the complete failure of a memory chip
as well as partial failures in other memory chips in the array.
recently spoke to Kent
Smith at LSI about this new product.
- dynamically adjusted power islands within the chip - enable a single
silicon design to support both the low requirements of deep sleep mode in SATA
notebooks as well as the performance requirements of entry level PCIe SSDs.
Our conversations about
SandForce SSD controllers go back more than 4 years - so we skipped a lot of
One of the first things I said to Kent - was - I've been
nagging you for years and asking - when are you going to do a native PCIe SSD
controller?- and for nearly 2 years it's been clear that another big hole in
LSI's SSD IP bag has been
- and now you've finally done both at the same time in a single product.
was also really impressed by the quality of LSI's
document on the LSI SandForce SF3700 (pdf) - which explains just about
everything you need to know. So I asked Kent - why does he need to waste time
talking to editor's like me? - why doesn't LSI just publish the document on the
web and let it speak for itself?
I said a lot of publications will
simply copy some of your pictures without attribution - and I think readers
would find it valuable seeing them too - but I think it would be fairer to the
work you've done if I could just make the whole document available - so there
was no doubt who had done the hard work of communicating what the design was all
He agreed to that - and you can click on the link above to see
the original info which I got from LSI.
Some other things I learned
from this conversations were:-
- The SF3700 is a completely new design. - It leverages all the flash
related design concepts related to endurance and array level fault management
which have been proven in earlier designs and extends them too.
example RAISE has been enhanced so that for high-end configurations it can
protect against a full memory chip failure as well as multiple block faults -
whereas entry level SSDs which need some RAID like features but can't afford an
extra memory chip can use fractional RAISE.
I think the SF3700 is a very ambitious and outstanding SSD controller design -
which will elevate LSI's reputation within the SSD industry.
- One of the reference designs which LSI offers for this controller is for an
M.2 form factor - which is
goiing to be the game changing SSD for the
next year. The card design is the same whether the SSD is being used as a
SATA or PCIe SSD. A single jumper sets the configuration at assembly time.
LSI's 2.5" reference design will also make it easier for oems to
produce products for enterprise arrays in the
2.5" PCIe SSD market.
Samsung enters PCIe SSD market

Samsung's XP941 - which weighs less than 6g - has a sequential read
performance of 1,400MB/s, and capacity up to 512GB.
market began the year before PCIe SSDs started being used in the
But in the first 5 years of its history (2006-2010) the
notebook SSD market was a disappointment to SSD evangelists like me - because
integration with PCs was so bad. And for years on these pages I ranted that
notebooks using SSDs would never be able to reach their true potential as long
as they were still wasting their inherently light CPU resources and latency
advantages by talking to the CPU via old fashioned
hard disk interfaces
exciting thing about today's announcement by Samsung is that consumer grade
PCIe SSDs for notebooks will enable a dramatically different user experience
which will help to create new markets.
Will there be a crossover into
the enterprise market?
It's inevitable that some people will ask -
what would an array of consumer priced PCIe SSDs look like in a box? And no
doubt you will probably see such products coming onto the market. And that
might lead to a temporary state of user confusion about expectations for PCIe
But setting aside for the moment the obvious considerations at
the single drive level of differences in
characteristics - I think the key differentiators of enterprise PCIe SSDs
compared to consumer
PCIe SSDs are the different degree of
(higher for the enterprise),
management and support for fault tolerance.

consumer SSD market
and notebooks - the M.2 form factor has begun creeping into
applications too - and is also likely to become a future standard adopted
M.2's key attractions are:-
smaller sizes for SSDs have been around for over a decade (for example the
1" and BGA sizes)
the M.2 size provides better volumetric packing densities for scaling storage
capacity by using arrays of M.2 SSDs in the same motherboard - compared to
traditional form factors. Therefore it provides an efficient platform which
spans many market needs - and is likely to be become as ubiquitous in SSD
product diversity as the 2.5" SSD has been.

2.5" SSDs). The
new M.2 size has been optimized for SSDs rather than inherited from the
hard drive market
