16GFC tech supported by DataCore|
Editor:- January 28, 2015 - Emulex today
announced that DataCore is
releasing target mode support in its new SANsymphony V10 software-defined
storage platform, for Emulex's Gen 5 (16GFC) HBA technology.
Western Digital invests in Skyera's MRAM supplier
January 26, 2015 - Western
Digital's investment unit was among the
investors in a $29
million series B funding round in Everspin Technologies
President and CEO of Everspin said "With a leading worldwide foundry and
storage customer participating in Everspin's Series B investment round, the
entire industry spectrum is acknowledging ST-MRAM as the leading contender to
drive beyond the limits of current mainstream memory."
comments:- Everspin's MRAM is
tier of the non volatile caching technology used in
Skyera - and my guess is that this investment in Everspin is to take out some of
the risk of future availability of these memory parts at a time when an assured
supply at higher volume may soon be needed.

Diablo appeals shipment injunction
says court was misled
January 14, 2015 -
that it has appealed the court ruling (reported earlier this week - and
initiated by Netlist)
which had granted a preliminary injunction to halt Diablo's shipments of Memory
Channel Storage based chipsets.
Diablo's appeal explains that the
ruling is based on an erroneous interpretation of the contract and a failure to
recognize the technology differences among the products involved.
importantly, however, the court did not find that Diablo MCS uses
Netlist trade secrets.
Diablo says - to support the judgment, the
order effectively rewrites the language in the contract signed by the parties in
2008: the additional words included in the order changed the terms of the
contract significantly and imposed a new obligation that was not agreed between
the parties. In other words, there was no violation by Diablo of the original
contract. The court was misled about important technology distinctions:
court relied on Netlist's representation that their HyperCloud and Diablo MCS "are
used to perform the same function" which is not the case because the
HyperCloud is DRAM (memory) and Diablo MCS is a block storage device (disk).
The court also relied on Netlist's representation that the products
are competitive because they both "attach to the same memory channel."
also says "Netlist equates the 2 devices simply because they use the same
location and i/o channel; extending that logic would equate all devices that
reside in PCIe slots, which would be a similarly erroneous claim."
"It is important that the facts of the case are well understood;
it should also be stressed that the court did not determine that Diablo uses
Netlist trade secrets," stated Riccardo
Badalone, CEO and co-founder of Diablo Technologies. "We offer an
innovative storage device that gives customers great performance advantages, but
with this injunction, the court is putting our company and our customers at
risk. With this appeal, we expect to reverse this decision and get back to
Editor's comments:- are Netlist's products functionally
different to those using Diablo's architecture?
Yes! The differences
are so great that the 2 products are listed in different directories here on
Channel Storage SSDs - which encompasses low latency, fast flash SSDs which
plug into DIMM sockets and transfer data via interfaces which were originally
designed for DRAM.
The fact that standards organizations and some vendors have
historically used the term "flash DIMM" in the context of both types
of products - has contributed to industry confusion.
- hybrid DIMMs, NV
DIMMs, flash backed DRAM DIMMs - which includes DRAM modules which
automatically save their contents when electrical power drops to an integrated
non volatile memory from which the data is reloaded after normal power is
But the term -
flash DIMM - is a description of the physical form factor - and tells you
nothing about the operation and functionality of the device from a data
architecture point of view.
The differences are vast and immediately
obvious to anyone who's technical. But I was wondering how would I explain the
gulf of difference to someone who doesn't know anything about computer design.
analogy goes like this... Suppose someone offered you the choice of 2 types of
backpack when you started a balloon ride.
One is a parachute, the
other is a jetpack.
They both perform different functions - although -
until you activate their functions they both might look the same.
I know you need a higher skillset to operate the jetpack.
also need a much more developed

ecosystem to deploy memory channel SSDs too.
California Court halts sales of ULLtraDIMM SSDs
January 13, 2015 - Netlist
that the US District Court for the Northern District of California has granted
Netlist's motion for a preliminary injunction against Diablo Technologies for
controller chips used by SanDisk
in its high-speed ULLtraDIMM SSD product line.
Under the court's
order, Diablo and SanDisk are prohibited from manufacturing and selling the
controller chipset used by SanDisk in the ULLtraDIMM and as a result, from
further sale or distribution of the ULLtraDIMM itself.
Rogers - also rejected SanDisk's motion for reconsideration, asking
that it be allowed to sell existing inventory of the enjoined products.
The court advanced the trial date to March 9, 2015, for Netlist's claims upon
which the motion was decided, including claims against Diablo for trade secret
misappropriation, breach of contract, and other causes of action related to the
components supplied by Diablo for the ULLtraDIMM.
The court's order
specifically identifies the ULLtraDIMM as well as the eXFlash modules from
IBM, although the
injunction affects all modules containing Diablo components.
comments:- the possibility of such a injunction has been discussed in
before. At the heart of the dispute are whether an earlier design collaboration
between Netlist and Diablo included the rights for both companies to use a
critical interface design in the DIMM bus facing part of Diablo's memory channel
storage design. A patent ruling on
December 29, 2014
upheld Netlist's patents related to this.
The court case related to
the injunction stems from Netlist's argument that if Diablo did not have the
right to use the interface technology - then it follows that any design - such
as the ULLtraDIMM SSD - which relies on such internal technology - should only
be disallowed - pending any future agreement about licensing such a technology.
(Which it may not choose to do.)
wants to create a low latency memory channel SSD product line of its own.
And even though Netlist is more than a year behind the productization
of this integrated technology (compared to the first generation ULLtraDIMM
designed Diablo and
SMART Storage -
which was acquired by SanDisk) the case from Netlist is that the market must
wait for its own design or any designs for which it grants licenses.
the Diablo side - its argument has been that they thought they had an
agreement which allowed them to use the DIMM interface technology (in whose
implementation they participated) in products which were different to Netlist's
flash backed DIMMs.
stake is a future market for server based accelerators which could be worth a
low double digit percentage of the entire
enterprise PCIe SSD market.
inconceivable that a small company like Netlist or Diablo would be able to
satisfy such demands on their own - especially given the fact that neither has
any core IP related to
But future licensing partners (or wouldbe
acquirers) need to be satisfied that the core technology they're using - is
