- wmf 1y agoCXL networking is still in the R&D stage.
- afr0ck 1y agoCXL uses the PCIe physical layer, so you just need to buy hardware that understands the protocol, namely the CPU and the expansion boards. AMD Genoa (e.g. EPYC 9004) supports CXL 1.1 as well as Intel Saphire Rapids and all subsequent models do. For CXL memory expansion boards, you can get from Samsung or Marvell. I got a 128 GB model from Samsung with 25 GB/s read throughput.
