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

by Zsolt Kerekes, editor - - 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.

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's 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." the article (pdf)

Xitore 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.
