3D XPoint - walking back the original claims
Editor:- December 6, 2016 - 3D XPoint: a Guide to the Future of SCM - a recent blog on Tom's Hardware keeps alive the ongoing story of this preannounced and over stated technology which was unveiled by Intel and Micron in 2015 as an investor oriented reassuring response to competitive announcements in the DIMM wars market - which pointed towards a much reduced market long term role for conventional server DRAM.

I - like others - stated my doubts about the so-called market readiness hinted at in the early 3DXPoint razzmatazz. And this year those early doubts have been salami sliced by successive analysis as more technical information has emerged or failed to emerge in support of the early bold claims.

This new blog by Paul Alcorn includes a nicely judged narrative and brings the story of the successive pilot show teasers up to date. Among other things Paul says:-

"unfortunately, the two companies recently began walking the performance claims back."

"...the companies have yet to explain, beyond ECC tuning, why the endurance specifications have taken such a drastic plunge."

"The ultimate goal of the next generation of memory is to have the worlds of storage and memories collide permanently, with just one medium emerging for both purposes. 3D XPoint isn't suitable for that role, at least not yet, but it could help lay the groundwork." ...read the article

Editor's comments:- this is what I said here in SSD news - August 2015...

"Much less easy to place within any particular calendar year and to rate for its significance to future SSD history - however - due to its distinctly vaporware-like aspects and stunning lack of technical details - was the stage managed unveiling of a newly branded memory architecture by Intel and Micron - which (like the emperor's new clothes) may or may not become significant for enterprise applications in 2016, or 2017 or 2018 - depending on when we can see it working and depending on what other competitors are doing at that time."

And in June 2016 - I brought reader attention to a thoughtful video - 3D XPoint, reality, opportunity, competition which looked at boundary capabilities of the technology from a competing semiconductor point of view.

I noticed that whenever I repeated the power off and power back on again cycling (into what we'd now call a "cold boot" condition) most of the contents of the RAM looked similar to what they had been before, instead of scrambled which is what I expected.

Inside SK Hynix's 3D NAND

Editor:- November 28, 2016 - a new blog - Inside SK Hynix's 3D NAND - on EE Times compares the memory density Gb/mm2 per tile of various leading 3D NAND die which are now available in the market.

Among other things the author - Jeongdong Choe, Senior Technical Fellow - TechInsights (a patent services company) - says "All of the 3D NAND players have their own unique cell structure, including FG-based and CTF-based cells. Which one would be better for 128 or higher stacked 3D NAND from the process integration and reliability viewpoint may be revealed in a couple of years."

WDC shows prototype RapidIO DRAM controller

Editor:- November 17, 2016 - Western Digital today said in a blog it will show a prototype memory controller aimed at big data which uses RapidIO as the interconnect at SC16.

"This new approach to incorporating SCM into the memory hierarchy can potentially provide the flexibility to deploy ultra-low latency, coherent SCM across high-performance computing and hyperscale environments, without disrupting compatibility with the existing infrastructure, scaling up to petabytes of data generated by applications and analytics in the age of "Big Data". ...read the article

Editor's comments:- The first mention of RapidIO here on StorageSearch.com was in March 2005 . More recently in May 2014 - I drew attention to a blog - Do You Really Know RapidIO? - by Eric Esteve , founder of IPnest who said - "Maybe it's time for the server/storage industry to give a second chance for the RapidIO protocol."


a winter's tale of SSD market influences - new blog on StorageSearch.com

Editor:- November 15, 2016 - Recently I spoke to AccelStor's President - Charles Tsai.

We talked about many changing influences in the SSD market. I thought you might be interested to see some of the things we spoke about in a new blog on StorageSearch.com - a winter's tale of SSD market influences - because it will give you an idea of how many strategic changes in the SSD market can now influence every business decision about what new products to create - even when those changing factors seem at first to be only loosely connected like the flash controller, industrial SSD, SCM, software and enterprise rackmount SSD markets. But all those factors entwined the flow of this SSD conversation which really started 2 years before. ...read the article

Editor:- November 3, 2016 - Elastifile today announced it has been granted a US patent (No. 9,465,558) for a method of flash-native, collaborative data storage when running on multiple interconnected nodes.

Elastifile's technology (which is integrated in software solutions) is aimed at the hybrid cloud market.

The patented technology enables efficient, distributed storage across full-mesh clustered architectures in which all nodes interact with one another across multiple sites and clouds, in complex or constantly varying network conditions, and/or at a scale that may encompass thousands of diverse configurations.

"One of the greatest challenges for private and hybrid cloud data services has been ensuring consistent performance for distributed data writing, especially due to noisy and mixed environments," said Ezra Hoch, chief architect at Elastifile. "Our patented approach adaptively and efficiently manages how and where data is written, mitigating the constantly changing conditions—at cloud scale."

December 2005 - Fusion-io was founded.

It would take a couple of years for the significance of this new company to become clear. Their technology and business approach changed the way that all commercial servers were designed and marketed so that all new enterprise servers included some kind of SSD based acceleration as a standard option.
