Samsung Electronics, in partnership with Red Hat, has successfully verified Compute Express Link (CXL) memory operations in a real user environment. This is the first time such verification has been achieved.

The advancement will allow data centre and enterprise customers to utilise CXL memory for high-performance computing without major hardware adjustments

Yongcheol Bae, Executive Vice President of Memory Product Planning at Samsung Electronics, said: “Our CXL partnership with Red Hat is an exemplary case of collaboration between advanced software and hardware, which will enrich and accelerate the CXL ecosystem as a whole.”

Optimising Memory Technology for Emerging High-Performance Computing Needs

The need for higher memory bandwidth and capacity has grown exponentially, driven by emerging fields like Generative AI, autonomous driving, and in-memory databases (IMDBs).

CXL, a unified interface standard connecting processors through a PCIe interface, addresses speed, latency, and expandability limitations in current systems.

Samsung has optimised its CXL memory for Red Hat Enterprise Linux 9.3, ensuring compatibility in Red Hat’s KVM and Podman environments. This development enables data centre clients to integrate Samsung’s CXL memory into their existing hardware setups.

Marjet Andriesse, Senior Vice President and Head of Red Hat Asia Pacific, said: “The successful verification of Samsung’s CXL Memory Expander interoperability with Red Hat Enterprise Linux is significant because it opens up the applicability of the CXL Memory Expander to IaaS1 and PaaS2-based software provided by Red Hat.”

Initiated with a memorandum of understanding in May 2022, the partnership between Samsung and Red Hat spans across various storage and memory products.

Their joint efforts at the Samsung Memory Research Center (SMRC) focus on developing CXL open-source and reference models, encompassing NVMe SSDs, CXL Memory, computational memory/storage, and fabrics.

This collaboration marks a pivotal step in integrating hardware and software for the next generation of memory development.
