Flash Memory Summit: Samsung, MemVerge, H3 Platform, and XConn Demo Memory Pooling and Sharing for Endless Memory

Joint demonstration eliminates Out-of-Memory errors to accelerate AI/ML workloads.

At FMS, Samsung Electronics Co. Ltd., MemVerge, Inc., H3 Platform, Inc., and XConn Technologies Holdings Inc., unveiled a 2TB Pooled CXL memory system.

The system addresses performance challenges faced by highly distributed AI/ML applications. These challenges include issues like spilling memory to slow storage when main memory is full, excessive memory copying, I/O to storage, serialization/deserialization, and Out-of-Memory errors that can crash an application.

Target problem and CXL to rescue
For modern applications such as AI/ML, demand is exploding for memory capacity and composability of memory in distributed computing environments. However, demand can’t be met because the capacity and composability of today’s system architecture is severely limited by the tight coupling between CPU and Memory.

In response, open CXL specs were developed to increase the capacity and composability of memory, and products have emerged that are being integrated into concept solutions.

Samsung led the creation of the first CXL memory module. MemVerge developed Project Endless Memory, the first elastic memory software that can scale memory capacity on demand. XConn delivered the first CXL switch and H3 Platform integrated the hardware and software components. The 4 companies co-engineered a 2U rack-mountable system with 2TB memory capacity that can be dynamically allocated to the computing hosts to meet the demands of modern applications.

The co-engineered 2TB Pooled CXL Memory System showcased at Flash Memory Summit features 8 Samsung 256GB CXL Memory Modules and the XConn XC50256 CXL 2.0 switch with 256 lanes. H3 Platform integrated hardware and firmware into a system that can be connected to as many as 8 computing hosts. MemVerge’s Project Endless Memory software runs on the hardware system, and helps users visualize, pool, tier, and dynamically allocate memory to the connected hosts.

The concept system unveiled at Flash Memory Summit is an example of how we are aggressively expanding its usage in next-generation memory architectures,” said JS Choi, VP, new business planning team, Samsung. “Samsung will continue to collaborate across the industry to develop and standardize CXL memory solutions, while fostering an increasingly solid ecosystem.”

The XC50256 is the first CXL 2.0 and PCIe Gen5 switch IC. The switch features up to 32-ports that can be bifurcated into 256 lanes with a total of 2,048GB/s switching capacity and low port-to-port latency.

According to Gerry Fan, CEO, Xconn: “Flash Memory Summit is the debut for systems using our switch ASIC. This generation of systems will deliver to AI applications lower latency and higher bandwidth than the previous generation of systems using our FPGA-based switches.

The Samsung CXL memory and XConn CXL switch come together in a 2U rackmount system.

H3 is leading the development of systems integrating a full stack of CXL hardware and software,” said Brian Pan, CEO and co-founder, H3 Platform. “Our leadership is highlighted by the H3 Fabric Manager which presents a friendly interface to the powerful CXL resources in the system.

The co-engineered demo system can be pooled, tiered with main memory, and dynamically provisioned to applications with Memory Machine X software from MemVerge and its elastic memory service. In addition, the Memory Viewer observability service displays the physical topology as well as a heat map of memory capacity and bandwidth usage by app.

Modern AI applications require a new memory-centric data infrastructure that can meet the performance and cost requirements of its data pipeline,” said Charles Fan, CEO and co-founder, MemVerge. “Hardware and software vendors in the CXL Community are co-engineering such memory-centric solutions that will deeply impact our future.”

Overviews of the 2TB Pooled CXL Memory System will be presented in the CXL Forum Community booth theater at FMS, over the 3 days of FMS, August 6-8. Demonstrations of Endless Memory are being presented at Flash Memory Summit in MemVerge booth.
