PMC-Sierra and the
Top SSD Companies List
Prior to its acquisition by
Microsemi in
January 2016 PMC
didn't enter the list of top 25 SSD companies based on search volume but it got
really close having got to being listed #26 in
Q3 2015.
As
we've often seen in the past 9 years of publishing this list those companies
which show promise (measured by reactions in the SSD market) are very likely to
go to the top of SSD
acquisition search lists. And when I talk to potential SSD company buyers
and investors the
importance of this list as a sanity check filter (other things being equal) is
well understood and recognized. |

PMC has now become a significant influence in the
enterprise SSD controller and interface IP market.
PMC is active in
these SSD market segments:-
PMC - which
a
decade ago in these pages was well known as a
RAID controller and
storage adapter IP company - has now become a significant influence in the
enterprise SSD market by a series of
acquisitions.

In May 2010 -
PMC-Sierra entered
the SSD market by announcing a
definitive
agreement to acquire Adaptec's channel
storage business for approximately $34 million in cash. This deal included
Adaptec's RAID storage product line, its global VAR customer base, board
logistics capabilities, and (most significantly)
SSD cache performance
solutions.
In May 2013 -
PMC-Sierra
announced a definitive agreement to acquire
IDT's enterprise
flash controller
business and certain PCIe switch assets for $100 million.
In December 2014 -
PMC-Sierra
announced that Memblaze
was using PMC's Flashtec NVMe controllers in its next-generation PBlaze4
PCIe SSD accelerators.
In January
2016 - Microsemi
completed the acquisition of
PMC-Sierra for $2.5
billion. |

From 2007 to 2014 - the
dominant focus and center of SSD accelerator gravity was PCIe SSDs.
It was the rapid domino-effect adoption of 3rd party PCIe SSD
accelerators by every mainstream server manufacturer - which changed the way
that SSDs were perceived from being an alienlike technology promoted by industry
outsiders to being a necessary option which was expected to be supported inside
every new server product line.
But the next chapter of the fast SSD accelerator story looks more
like a DIMM. |

| PMC blog discusses latency
implications of DSP ECC IP in SSD controllers |
Editor:- May 15, 2014 -
Latency
in LDPC-based Next-Generation SSD Controllers is a new blog by Stephen Bates,
Technical Director, PMC
who says - "The variability of the LDPC decode time is a function of how
many iterations it takes to decode the data from the flash."
In
his article Stephen says that the minimum number of iterations is 1, typical
is 4 and maximum is 20.
To relate that to latency - he says assume for
sake of illustration that each iteration takes a microsecond. | | |
