Future of Persistent Memory, DRAM, and SSD Form Factors Aligned with New System Architectures

Arthur Sainio, Director, Product Marketing, SMART Modular Technologies 


The options for memory expansion and system acceleration are growing and starting to align with emergent serial and fabric attached architectures.  Application responsiveness and system performance are key values for end users.  Modern data workloads require real-time processing of large data-sets resident in main memory But, memory capacity has not scaled as compared to the number of CPU cores available in modern day servers. The new serial and fabric attached interconnect architectures (CXL, OpenCAPI, Gen-Z,) enable the use of other form factor like EDSFF E1.S and E3.S for memory expansion and acceleration use-cases. Application and hardware requirements are driving selection of form factors best suited for adding cache coherent serial or fabric attached memory.

The Persistent Memory Connection - How to Attach PM in Computing Systems?

Jonathan Hinkle, Executive Director and Distinguished Researcher, Systems Architecture, Lenovo


Persistent Memory is being used today to speed a wide range of applications from traditional workloads like database and storage to emerging AI and edge workloads.  As with many new technologies, use of PM started as adapted to existing system implementations for benefit of first adoption, from NVDIMM-N to 3DXP NVMe drives.  Now after further progress, it’s more clear how to optimize the means of interfacing to PM in computing systems for maximum benefit.  This session will chart the journey from early implementations to near-future architectures that will truly unlock the strong value of PM, plus share some real results from next-gen hardware prototyping.

NVMe Computational Storage: A New Hope for Accelerators and DPUs

Stephen Bates, Chief Technology Officer, Eideticom


Computational Storage offers the promise of a vendor-neutral and open-standard for moving parts of applications from a host to an accelerator. In this talk we will look at the promise and potential of the work being done within SNIA and NVMe to standardize how host CPUs communicate and offload tasks to NVMe Computational Storage devices.  This is the first time a device-level open standard is being developed for computation devices. We predict this will enable a vendor-neutral ecosystem around accelerators, DPUs and Computation Storage devices that will lead to a new level of adoption. We will lay out our vision of this and Eideticom's role, products and customer successes in this new and exciting world!

CXL 2.0 - Architecture and Benefits for Computational Storage

David Wang, Director, Memory Product Planning, Samsung Electronics


Released in November 2020, the CXL™ 2.0 Specification added new features and functionality, including support for switching enabling device fan-out, memory scaling, expansion and the migration of resources; memory pooling for increased memory utilization efficiency; and support for persistent memory – all while maintaining full backwards compatibility with CXL 1.1 and 1.0.

The CXL 2.0 architecture enables computational storage. CXL moves persistent memory and storage together in a way that it is no longer a singular order of compute, memory and storage. Rather than the traditional inline process of going from compute to memory to storage and back, CXL can go from compute directly to storage, or from compute to memory and memory straight to storage.

In this presentation, attendees will learn about the CXL 2.0 architecture, as well as its benefits for computational storage.


Security in Computational Storage Drives  

David McIntyre, Director, Product Planning and Business Enablement, Samsung Corporation


Data storage growth continues to increase the demand for additional compute resources to run applications in the cloud and at the edge. In situ processing within a solid state drive or array of drives provides a more efficient approach of bringing compute resources to the data, where applications can be accelerated in performance without the necessity of sending the data to the host processor complex. With computational storage, the stored data can be more resilient with improved security measures by reducing data in-flight between host compute and solid state drives. This presentation will provide an overview of security challenges and proposed solutions to address the policy requirements of cloud service providers and enterprise customers that can benefit from this approach to better meeting the processing demands required on exponentially growing data and storage requirements.

The Challenges of Measuring Persistent Memory Performance 

Eduardo Berrocal, Sr. Software Engineer, Intel and Keith Orsak, Master Technologist, Hewlett Packard Enterprise


With multiple types of persistent memory in the market today, and many more potentially coming in the future, defining a way to consistently measure performance can be a challenge.  The SNIA Solid State Storage (S3) Technical Work Group (TWG) has undertaken an effort to define and test persistent memory, both in drive and raw memory format.  The most recent effort is the Performance Test Specification (PTS).  This talk will discuss the test and cover: Test Methodology; platform setup; synthetic and real-world workloads; and reporting format for test results. The PTS will enable an understand of both block and byte-addressable memory performance for accurate comparison in the real world.

State of the Computational Storage Market - a Supplier's View

Scott Shadley, Co-Chair, SNIA Computational Storage Technical Work Group/VP Marketing, NGD Systems


When doing research on the topic of Computational Storage, there is a lot of content that continues to surface from both vendors and now more importantly the editors, authors of major outlets like EnterpriseAI and TechTarget. Even the Analysts, like IDC, 451 Research and most recently Gartner are getting into the mix. The goal of this conversation is to look at some of the industry conversations, showcase where current vendors are in deployments with use cases they have shared and see where the logical integration point will occur from a standardization (SNIA, NVMe, etc) and customer adoption to mass deployments. The Compute infrastructure as we know it is continuing to evolve, first with production and adoption of PM products, and not with the additional of Computational Storage solutions. But there is also a need to know what is right, wrong, deployable and cause for concern. A walk through the evolution of all these items will be portrayed and leave the attendee with a better understanding the market direction. Stay tuned and find out about all the Hype.

Four Top Use Cases for Big Memory Today and Tomorrow

Dr. Charles Fan, CEO and Founder, MemVerge 


Big memory computing consists of DRAM, persistent memory, and big memory software like Memory Machine from MemVerge, all working together in a new class of software-defined memory. During the first year since MemVerge unveiled big memory in May of 2020, four strong use cases emerged: 1) in-memory databases, 2) cloud infrastructure, 3) animation and VFX, and 4) genomics. All share a critical need for composable memory with capacity, performance, availability, mobility, and security that can be tailored for the app. They are also demanding memory infrastructure with the capacity to handle massive data sets and avoid the performance hit of IO to storage. In this session, Dr. Charles Fan will provide a detailed overview of the memory-related problems for each use case and how big memory addressed each challenge. He will also briefly review four uses expected to emerge in the future.

Practical Computational Storage:  Performance, Value, and Limitations

Bradley Settlemyer, Sr. Research Scientist, Los Alamos National Labs   


Ongoing standardization efforts for computational storage promise to make the offload of data intensive operations to near-storage compute available across a wide variety of storage devices and platforms. However, many technologists, storage architects and data center managers are still unclear on whether computational storage offers real benefits to practitioners. In this talk we describe Los Alamos National Laboratory’s ongoing efforts to deploy computational storage into the HPC data center. We focus first on describing the quantifiable performance benefits offered by computational storage; second, we present the economic case that motivates deploying computational storage into production; and third, we describe the practical limits that exist in applying computational storage to data center storage systems.

Why Distributed AI Needs Computational Storage

Michael Kagan, CTO, NVIDIA


Artificial Intelligence is increasingly being used in every type of business and industry vertical including finance, telco, healthcare, manufacturing, automotive, and retail. The nature of AI is becoming distributed across multiple nodes in the data center but also across the cloud and edge. Traditional local and networked storage solutions often struggle to meet the needs of AI running on many different types of devices in various locations. Computational storage can solve the challenge of data locality for distributed AI. These solutions include smart storage devices, adding data processing to storage arrays, and deploying new types of compute processors in the storage, next to the storage, or even in the storage network.

Beyond Zoned Namespace - What Do Applications Want?

Chun Liu, Chief Architect, Futurewei Technologies 


When data processing engines are using more and more log semantics, it’s natural to extend Zoned Namespace to provide a native log interface by introduce variable size, byte append-able, named zones. Using the newly introduced ZNSNLOG interface, not only the storage device enables less write amplification/more log write performance, but more flexible and robust naming service. Given the trends towards a compute-storage disaggregation paradigm and more capable computational storage, ZNSNLOG extension enables more opportunities for near data processing.

A New Path to Better Data Movement within System Memory, Computational Memory with SDXI

Shyam Iyer, Chair, SNIA SDXI Technical Work Group; Distinguished Engineer, Dell 


Today, computation associated with data in use occurs in system memory. As the system memory envelope expands to includes different tiers and classes of memory helped by memory fabrics, data in use envelope increases.  In many usage models, moving data to where the computation occurs is important. In other usage models, data copies are needed for compute scaling. Data movement is a resource intensive operation used by a variety of software stacks and interfaces. Offloading data movement frees up chargeable compute cycles.

While the ability to use offloads have existed, they have not been easy to integrate into various user and kernel level software stacks. The industry needs a standard offload data movement interface. Additionally, a standard data movement interface that envisions offloading other computations involving system memory is highly desirable.

This talk will connect the audience with SNIA’s SDXI (Smart Data Acceleration Interface) TWG’s efforts in this space. SNIA’s SDXI TWG is standardizing a memory to memory data movement and acceleration interface.
