    Not a Tempest But a Seachange – Persistent Memory

    October 12th, 2016

    by Marty Foltyn

    Persistent memory discussions are capturing the minds of SNIA members and colleagues.  At last month’s SNIA Storage Developer Conference, NVM (non-volatile memory) and NVMe sessions were standing-room-only, and opinion sharing continued into animated hallway discussions.  I encourage you to check out the many presentations on the SNIA SDC website, and to download the live recordings of the keynotes here.

    memconSNIA continued their education on persistent memory at this week’s Memcon in Santa Clara CA. SNIA’s booth was packed with attendees asking questions like what is the difference between the different kinds of NVDIMMs (you’ll want to check out our new snia_nvdimm_infographic), and is NVDIMM a standard (indeed, it is, JEDEC just released the DDR4 NVDIMM-N Design Standard Revision 1.0 last month, and you can download the link from our website).

    pm-video-jimThe work being done within SNIA on persistent memory is contributing to a seachange in the industry – the convergence of memory and storage – perhaps the most revolutionary change since the invention of the transistor more than 60 years ago.  To learn more, check out this interview with Jim Pappas, SNIA’s Vice-Chairman and co-chair of the SNIA Solid State Storage Initiative.  And mark your calendar for January 18, 2017, when SNIA will hold the 5th annual Persistent Memory Summit in San Jose CA.  The latest details can be found here.

    Assessing SSD Performance in the Data Center

    October 20th, 2015

    By Marty Foltyn

    As solid state drives (SSDs) are deployed in datacenters around the world in both hybrid HDD/SSD and all flash arrays (AFAs), it is becoming increasingly important to understand what metrics are relevant to assess SSD datacenter performance. While the traditional metrics of IO operations per second (IOPS), Bandwidth, and Response Times are commonly used, it is becoming more important to report and understand the ‘Quality of Service’ of those metrics.

    eden articleEden Kim, Chair of the SNIA Solid State Storage Technical Working Group, has recently authored an article on Understanding Data Center Workloads. In it, he defines workloads and specifically data center workloads, describes how they are tested, and shows how to measure workloads for performance analysis. Industry standard test methodologies that ensure fair and accurate testing of SSDs both at the device and system level are described, along with how to use them on a reference test platform, Eden also describes in depth Response Time Confidence levels and how an understanding of Demand Variation and Demand Intensity can help the IT administrator assess how a given SSD or array will perform relative to the requirements of an application workload or relative to a specific Response Time Ceiling thus helping in the overall system optimization, design, and deployment.

    Read Eden’s full article on the SNIA Solid State Storage Education page at http://www.snia.org/forums/sssi/knowledge/educationBy. Scroll down to “Performance” to find this and a whole range of white papers, tech notes, webcasts, and presentations on this important Solid State Storage topic.


    SSD Data Retention Issue Debunked

    June 1st, 2015

    For the past few weeks, there has been quite a commotion on tech sites, and it was all because of a 5 year old presentation. Someone discovered a set of slides created in 2010 by then-chair of the JEDEC SSD committee, Alvin Cox of Seagate. That person misinterpreted one of the slides to mean that unpowered SSDs would retain data for only a few days in a hot room. It was reported on one site and of course picked up by several others, spreading quickly across the spectrum of sites reporting on technical matters. Finally, Alvin and a colleague gave an interview to PCWorld (www.pcworld.com/article/2925173/debunked-your-ssd-wont-lose-data-if-left-unplugged-after-all.html) setting the record straight, stating that a scenario that might cause data loss is highly unlikely, especially for consumers.

    NVM Programming Model Recognized for Enterprise Business Innovation

    August 21st, 2014

    At the most recent Flash Memory Summit in August 2014, the SNIA NVM Programming Model was selected for a singular honor – industry recognition as a Best of Show for Enterprise Business Applications.  Being recognized was quite unique, as the Model is not a product or a solution as were other winners in the various categories; but rather a body of work that defines new software programming models for non-volatile memory, also known as NVM.

    NVM technologies are currently advancing in such a way as to blur the line between storage and memory – which will radically transform the way software is written. The NVM Programming Model embraces this transformation, describing behavior provided by operating systems that enables applications, file systems, and other software to take advantage of new NVM capabilities.

    The Model addresses NVM extensions for existing devices such as SSDs and persistent memory, describing the differences between software written for block storage (SSDs and disks) and persistent memory, and outlining the potential benefits for adapting software for persistent memory.

    In presenting the Award to Doug Voigt, co-chair of the SNIA NVM Programming Technical Work Group, Jay Kramer, Chairman of the Flash Memory Summit Awards Program and President of Network Storage Advisors Inc., stated,  “Flash memory technology is currently experiencing a progression of innovations that can make a real difference in solving storage solution challenges. The industry is seeing a proliferation of new Non–Volatile Memory (NVM) functionality and new NVM technologies.  We are proud to select the SNIA NVM Programming Model for the Best of Show Award as it brings to the marketplace a new standard with a model that defines recommended behavior between various user spaces and operating system (OS) kernel components supporting NVM.”

    Congratulations to the many SNIA member company contributors to the Programming Model for this honor!  For information and to download the specification, visit http://www.snia.org/forums/sssi/nvmp.
