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". the article

Editor's comments:- The first mention of RapidIO here on 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

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 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. the article

SSD cloud
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."
