CXL couldn't be utilized until there was a server platform that supported it, so we're very excited to see AMD launch their next-generation Epyc server platform, code-name Genoa. In this episode of Utilizing CXL, Stephen Foskett and Craig Rodgers talk with Mahesh Wagh of AMD and the CXL Consortium about this important release. The first step to bring CXL to market is to prove it is functional and performs well with a mainstream platform like AMD 4th-generation Epyc. AMD is bringing CXL to market as a tiered memory solution that performs similar to as memory on a remote NUMA socket without any special configuration or software. But AMD also supports other memory technologies, including hierarchical memory with software, security, pooling, and even memory sharing with specialized software. Although Epyc is said to only support CXL 1.1, later spec devices will be backwards-compatible and the platform also supports some CXL 2.0 features including global flush for persistent memory, firmware-first error handling, and device-specific capabilities.
