Is SSD with CXL interfaces brilliantly stupid or stupidly brilliant?

Modern enterprise and data-center workloads are all hitting the memory wall—both bandwidth and capacity walls. This has led to new memory-centric computing architectures and an industry-wide adoption of the new Compute Express Link (CXL) standard to overcome the memory capacity wall problem. This is accomplished by providing memory expansion over the PCIe physical interface via low latency cache-coherent communication protocols. To learn more, join Rekha Pitchumani, Senior Manager, Memory Solutions Lab, on Thursday, April 20th at 10:00am PT as she does a deep dive into the CXL-based Memory-Semantic SSD™, one of Samsung’s recent memory innovations. This innovation is designed to overcome the memory capacity wall using a high-performance SSD architecture with a fine-grained cache-line granular memory access interface.

A Memory Technology Continuum to Be Enabled by CXL

Presenter : Yangseok Ki, VP, Samsung Memory Solutions Lab

CXL is a buzzword, but still unfamiliar to many people in the industry. In this lecture, Dr. Ki will provide an overview of CXL, focusing on the potential and limitations of behavioral characteristics learned through Samsung’s development of various CXL PoCs. In particular, he will focus on the role of CXL as a common system fabric. He will explain how CXL accelerates the convergence of memory, storage, accelerators and networks for computing and creates a new continuum of memory technology.

Why Should the Storage Community Care about CXL?

Presenter : Yangseok Ki

The exponential growth in data volume and traffic across the global internet infrastructure is motivating the exploration of new architectures for data centers to achieve the demand for better performance, efficiency and total cost of ownership (TCO). One promising trend is to segregate the functional components of compute, memory, storage, and networking into pools and organize them as needed according to the specific needs of different workloads. This disaggregation and composability will take us beyond the classic architecture of servers as the unit of computing.

Backed by a broad consortium of hyperscalers, equipment OEMs, chipmakers and IP vendors, Compute Express Link (CXL) is a new enabling technology for interconnecting computing resources that embraces existing competing technologies such as Gen-Z and OpenCAPI. Currently in Gen 3.0, CXL enables high-speed, low-latency links with memory cache coherency between processors, accelerators, NICs, memory, and storage.

In this keynote, Dr. Ki would like to share the opportunities and challenges that exist across hardware and software, with a focus on Samsung’s CXL memory technologies such as CXL memory expanders and memory semantic SSDs. In particular, he will share the direction Samsung wants to move forward with the storage community and suggest various collaboration opportunities.

Evolution of Memory Devices for Edge Computing

Presenter: Dr. Sungwook (Sung) Ryu, Samsung

Computer system architecture has been changing due to new application requirements and evolution of hardware. Mainframe computer used to be a prevail solution but distributed workstations, cloud, and edge computing have been adapted. I will go over what have been driving the architecture changes and talk about the detailed requirements of edge computing. Samsung is developing memory devices for edge computing, which include Computational Storage, ZNS (Zoned Namespace) SSD, PIM (Processing In Memory), and MRAM. I will discuss how these devices can address the issues on edge computing for power, latency and form factor.
