Xitore, Inc., founded in 2014,
and based in Southern California, describes itself as "a leading provider
of high bandwidth, low latency DATA-Storage products."

| Who's who in SSD? - Xitore | |

- March 2016
Xitore exited stealth mode in
February 2016.
The
company (which hasn't launched a product yet) appears to be aiming at the
SSD DIMM wars
market.
Xitore says its technology - which connects directly to the
DRAM bus - has the capability of providing 1TB to 4TB SSD storage in a single
DIMM slot while exceeding 20GB/s bandwidth and upto 4 million IOPS while
always delivering latency better than 2 microsends.
This capability
envelope (although we need to know more to be sure) would position Xitore's
technology as having applications in flash as RAM tiering or
memory channel
SSD markets. |

decloaks into SSD DIMM wars market |
Editor:- February 1, 2016 - Another new name
coming into in the SSD
DIMM wars saga
is Xitore which
exited stealth mode today with an announcement about their
NVM-X technology - which
promises "sub-2 microsecond latency" and 25GB/s bandwidth.
Editor's
comments:- Xitore's web site currently has almost no information about its
product details beyond the headline claims.
The company, founded in
2014,
and whose management team includes experience in SSD companies related to
enterprise acceleration (including
STEC and
Netlist), says it's
looking for first-round funding.
In outline Xitore's technology mix
sounds similar to Diablo
- but with these apparent differences:-
- shipping sampling status - Diablo has been shipping and sampling products,
whereas Xitore doesn't say anything about that yet
- form factor for end product - Diablo's form factor ambitions start and end
in DIMMs. Xitore's web site implies that it is aiming to provide storage in a
box - which sounds like an SDS box in which the RAM tiering is the key element
but not the whole solution. (Maybe the flash is implemented by COTS SSDs.)
We'll
have to wait for more details to emerge. | | |

| As enterprise RAM
performance is progressively bounded more by controller traffic analysis needs
and power consumption rather than DRAM cell capability - there's an argument for
saying if the statistical distribution of DRAM latencies is so wide - maybe no
one would notice if you slipped in a different kind of memory in the virtual
slider mix. |

| Xitore envisions NVDIMM
tiered memory evolution |
Editor:- February 7, 2017, 2017 - "Cache
based NVDIMM architectures will be the predominant interface overtaking NVMe
within the next 5-10 years in the race for performance" - is the concluding
message of a recent presentation by Doug Fink , Director of
Product Marketing - Xitore
-
Next
Generation Persistent Memory Evolution - beyond the NVDIMM-N (pdf)
Among other things Doug's slides echo a theme discussed
before - which is that
new memory media (PCM, ReRAM, 3DXpoint) will have to compete in price and
performance terms with flash based alternatives and this will slow down the
adoption of the alt nvms.
Editor's
comments:- Xitore (like others in the
SCM DIMM wars
market) is working on NVDIMM form factor based solutions and in this and
an earlier
paper
they provide a useful summary of the classifications in this module
category.
However, the wider market picture is that the retiring and
retiering DRAM story cuts
across form factors with many other permutations of feasible implementation
possible.
So - whereas the NVDIMM is a seductively convenient form
factor for systems architects to think around - the competitive market for big
memory will use anything from SSDs on a chip upto (and including) populations of
entire fast rackmount SSD boxes as part of such tiered solutions - if the
economics, scale, interface fabric and
software make the
cost, performance and time to market sums emerge in a viable zone of business
risk and doability.

NVDIMM-X - comparison white paper |
Editor:- September 27, 2016 - If you're
interested in a single document which summarizes most of the DIMM wars products
in the market today - take a look at this -
Introducing
NVDIMM-X (pdf) - an architectural white paper by Xitore which is
creating this "-X" technology.
This paper was brought to my
attention today by Xitore's CEO - Mike Amidi, CEO - who
said in his email - "This can be a good article to explain the main
difference between all non-traditional DRAM based solution sitting on DRAM
memory bus. Either persistence, non-persistence, or SSD-on-A-DIMM." ...read
