Enfabrica: Scaling CXL Memory Using High Speed Networking

Shrijeet Mukherjee, Co-Founder & CDO of Enfabrica explains how memory access using the standardized CXL.mem interface is a game changer in the data center. While NUMA based memory scaling has been attempted by various companies in the past, the ubiquity of this interface can shift data center architectures forever. However, computer systems also evolved away from scale up designs to enable loosely coupled, unshared fate systems built around networking as the way to communicate and using RDMA as the way to share memory. In my talk, we will explore the implications of having massive amounts of networking bandwidth coupled with CXL memory hierarchies and the designs that yield the best overall characteristics.
