The Revolution of Memory and Storage Side Processing: How Persistent Memory Will Bring an Entirely New Structure to Large Data Computing

Stephen Pawlowski, Vice President, Advanced Computing Solutions, Micron Corporation


As data proliferation continues to explode, computing architectures are struggling to get the right data to the processor efficiently, both in terms of time and power. But what if the best solution to the problem is not faster data movement, but new architectures that can essentially move the processing instructions into the data? Persistent memory arrays present just such an opportunity. Like any significant change, however, there are challenges and obstacles that must be overcome. Industry veteran Steve Pawlowski will outline a vision for the future of computing and why persistent memory systems have the potential to be more revolutionary than perhaps anyone imagines.

The SNIA NVM Programming Model: Latest Developments and Challenges

Andy Rudoff, Member, SNIA NVM Programming Technical Work Group and Architect Datacenter Software, Intel Corporation


In this presentation, Andy will report on the latest developments around the SNIA NVM Programming Model, especially focusing on Persistent Memory Programming.  The model has continued to evolve but also some new, interesting challenges have come up.  Andy will summarize the current support for Persistent Memory programming in operating systems and libraries, and give us a peek at upcoming work to address the challenges.

Beyond NVDIMM: Future interfaces for Persistent Memory

Stephen Bates, Global Engineering Head, Sr. Technical Director, Microsemi


NVDIMMs are awesome! You can buy them today, put them into today's systems and start to see the potential of what Persisent Memory (PM) can do for your systems and applications. They are a window into the computing world of the future. However, with that said, there are limitations to NVDIMMs and alternatives to them in terms of PM  deployment. In this talk we will dig into some of the NVDIMM alternatives that are available today and will be available tomorrow. We will compare and contrast these alternatives and discuss what has to happen for some of these alternatives to come to market

Persistent Memory over Fabrics – an Application-centered View

Paul Grun, Open Fabrics Alliance Vice Chair; Advanced Technology Group, Cray, Inc
Doug Voigt, Chair, SNIA NVM Programming Technical Work Group and Distinguished Technologist, Hewlett Packard Enterprise


This session begins with a short discussion between SNIA and the OpenFabrics Alliance exploring the relationship between the two organizations as viewed from the point of view of the consumer of fabric-attached persistent memory services. The session will touch on the role of SNIA’s NVM Programming Model TWG in defining the set of services exposed to the consumer; the OFA section of the talk will explore some thoughts about possible directions for network APIs to deliver those services to the consumer.

Bringing Persistent Memory Technology to SAP HANA: Opportunities and Challenges

Zora Caklovic, Product Expert, SAP Hana Products and Innovation, SAP SE


The emerging Persistent Memory technology with its promise for enormous capacity, memory-like speed and non-volatility is a real game changer for in-memory database systems like SAP HANA. In this talk, we will discuss the tangible benefits that we expect this technology will bring to SAP HANA as we move from standard DRAM to Persistent Memory NVDIMMs, specifically enabling large customer data sizes at a lower cost as well as significant improvements in  database restart times. Finally, we will give a glimpse of how we are evolving the SAP HANA architecture to incorporate NVDIMMs. We’ll discuss some of the challenges arising from having a hybrid DRAM + NVDIMM memory with lower bandwidth and higher latencies and how we are  planning to overcome them. 

NOVA: The Fastest File System for NVDIMMs

Steven Swanson, Professor in the Department of Computer Science and Engineering at the University of California, San Diego and the Director of the Non-volatile Systems Laboratory


We present NOVA, a free, open-source, Linux file system designed to maximize performance on NVDIMM-based storage systems while providing strong consistency guarantees.  Experimental results show that, on write-intensive workloads, NOVA provides a 2.5x times greater throughput and 4.5x lower latency than EXT4-DAX and is as fast or faster than any other currently available NVDIMM file system.  NOVA also provides strong data and metadata integrity guarantees in the face of NVDIMM media and system failures.  The talk will describe NOVA’s design, features, and performance characteristics.

Storage at Memory Speed and the Amazing Future of Virtual Non-Volatile Memory

Rajesh Venkatasubramanian, Principal Engineer at VMware


Non-volatile memory (NVM) is an exciting technology that offers persistence at near memory speeds in large enough capacity to change the storage vs. memory paradigm used by applications such as databases, analytics and filesystems. In this session, you will hear how VMware is working to ensure vSphere can deliver the improved performance and capacity of NVM with the virtualization benefits of workload agility and optimized consolidation. We will also preview NVM's potential by sharing results from our persistent memory-aware Redis port.

Persistent Memory In Linux

Tom Coughlan, Senior Engineering Manager, Red Hat


This talk will give an overview of the current state of persistent memory support in the Linux operating system. The various software components will be described, and a step-by-step guide for how to configure, use, and manage persistent memory will be given. This will include block-access mode as well as byte-addressable Direct Access (DAX) mode. We'll end with a discussion of future development plans for persistent memory in Linux.

How Might Recently Formed System Interconnect Consortia Affect PM?

Doug Voigt, SNIA Technical Council member


In October 2016 three new system interconnect consortia emerged that could change the way persistent memory is integrated.  Although their value propositions differ their combined effect relates to the scale of memory systems and the way memory integrates with computation and storage.  This session summarizes the motivation and direction taken by the Gen-Z, Open CAPI,and CCIX consortia and how they might affect persistent memory.

Panel: Persistent Memory Adoption in Operating Systems

Moderator: Jeff Chang, SNIA NVDIMM SIG Co-Chair and VP Marketing and Business Development, AgigA Tech
Panelists: Tom Coughlan, Red Hat; Amit Golander, Plexistor; Pratap Subrahmanyam, VMware; Tom Talpey, Microsoft


Operating Software has made significant progress in the adoption of NVDIMM. Operating systems are now releasing the latest versions that include NVDIMM support. These operating systems will expose the potential of NVM in 2017. This panel will give an overview of the current state of persistent memory in the Linux (RHEL, Fedora, SUSE, VMware) and the MSFT kernel.
