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.
SNIA 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).

If you are in Silicon Valley or the Bay Area this week, SNIA welcomes you to join them and the Solid State Storage Initiative April 13-14 at the Santa Clara Convention Center for Open Server Summit 2016, the industry’s premier event that focuses on the design of next- generation servers with topics on data center efficiency, SSDs, core OS, cloud server design, the future of open server and open storage, and other efforts toward combining industry-standard hardware with open-source software.
The SNIA NVDIMM Special Interest Group is featured at OSS 2016, and will host a panel Thursday April 14 on NVDIMM technology, moderated by Bill Gervasi of JEDEC and featuring SIG members Diablo Technology, Netlist, and SMART Modular. The panel will highlight the latest activities in the three “flavors” of NVDIMM , and offer a perspective on the future of persistent memory in systems. Also, SNIA board member Rob Peglar of Micron Technology will deliver a keynote on April 14, discussing how new persistent memory directions create new approaches for system architects and enable entirely new applications involving enormous data sets and real-time analysis.
SSSI will also be in booth 403 featuring demonstrations by the NVDIMM SIG, discussions on SSD data recovery and erase, and updates on solid state storage performance testing. SNIA members and colleagues can register for $100 off using the code SNIA at http://www.openserversummit.com.
The debate between hard drives and solid state drives goes on in 2016, particularly in the area of areal densities – the actual density of storage on a device. Fortunately for us, Tom Coughlin, SNIA Solid State Storage Initiative Education Chair, and a respected analyst who contributes to Forbes, has advised that flash memory areal densities have exceeded those of hard drives since last year!
Coughlin Associates provides several charts in the article which map lab demos and product HDD areal density since 2000, and contrasts that to new flash product announcements. Coughlin comments that “Flash memory areal density exceeding HDD areal density is important since it means that flash memory products with higher capacity can be built using the same surface area.”

The discussion, use, and application of Non-volatile Memory (NVM) has come a long way from the first SNIA NVM Summit in 2013. The significant improvements in persistent memory, with enormous capacity, memory-like speed and non-volatility, will make the long-awaited promise of the convergence storage and memory a reality. In this 4th annual NVM Summit, we will see how Storage and Memory have now converged, and learn that we are now faced with developing the needed ecosystem. Register and join colleagues on Wednesday, January 20, 2016 in San Jose, CA to learn more, or follow http://www.snia.org/nvmsummit to review presentations post- event.
The Summit day begins with Rick Coulson, Senior Fellow, Intel, discussing the most recent developments in persistent memory with a presentation on All the Ways 3D XPoint Impacts Systems Architecture.
Ethan Miller, Professor of Computer Science at UC Santa Cruz, will discuss Rethinking Benchmarks for Non-Volatile Memory Storage Systems. He will describe the challenges for benchmarks posed by the transition to NVM, and propose potential solutions to these challenges.

A classic case of SNIA Solid State Storage Initiative (SSSI) member collaboration for industry advancement was on display in the SSSI booth for NVDIMM-N demonstration at the Flash Memory Summit (FMS) 2015. Under the direction of SSSI Chair Jim Ryan and coordinated by NVDIMM SIG co chairs Arthur Sainio and Jeff Chang and TechDev Committee chair Eden Kim, the SSSI was able to update and include NVDIMM-N storage performance in the SSSI marketing collaterals on the Summary Performance Comparison by Storage Class charts.
Five SSSI member companies – AgigA Tech, Calypso, Micron, SMART Modular, and Viking Technology – collaborated over a four week period on the introduction of a new NVDIMM-N storage performance demonstration. While it is rare to have potential competitors collaborate in such a fashion, NVDIMM-N storage represents a new paradigm for super fast, low latency, high IO/watt storage solutions. The NVDIMM-SIG has taken a leadership position by evangelizing the technology and developing the industry infrastructure necessary for large scale deployment.
This collaboration highlighted a classic blend of technical, marketing and industry association cooperation.
In the weeks leading up to FMS, the NVDIMM-SIG planned for an in-booth demonstration of the NVDIMM-N storage modules. To pave the way for universal adoption, the team worked together to dial in the Intel Open Source block IO development driver to meet the standards of the SNIA Performance Test Specification (PTS). An added goal was inclusion of NVDIMM-N modules as a new line item on the Summary Performance Comparison by Storage Class chart which lists PTS performance for various storage technologies. Under the guidance of NVDIMM-SIG, a rush project was instigated to get NVDIMM-N performance data tested to the PTS for the trade show.
Micron took the lead by lending a Supermicro server with Micron NVDIMM-N to Calypso for testing. Calypso then installed CTS test software on the server to allow full testing to the PTS. Viking and SMART Modular contributed by helping dial in the drivers, as well as sending modules from Viking and SMART Modular to cross reference with the Micron modules. The test plan was comprised of several test iterations using single, dual and finally quad modules using each of the vendor contributed modules.
The early single and dual module tests ran into repeatability and stability issues. NVDIMM-SIG consulted with Intel on the nuance of the Intel block IO driver while Calypso continued testing. The team successfully completed a test run that met the PTS steady state requirements on the quad module in time to release data for the show.
We had a solid demonstration at the SNIA SSSI Flash Memory Summit Booth on NVDIMM-N Performance complete with marketing collateral available for review and a handout. NVDIMM-SIG members responded to the many questions and interest in the NVDIMM-N storage technology.
“Once again,” said SSSI Chair Jim Ryan, “we can see the value and benefit of SNIA SSSI to its members, the SNIA educational community and the NVDIMM industry. I believe this is a great case study in how we all can contribute and benefit from working within the SSSI for the betterment of individual companies, market development and the Solid State Storage industry at large.” SSSI provides educational and marketing materials free of charge on its public website while SNIA SSSI members may join the NVDIMM-SIG and other SSSI committees.
