    CXL 3.0 is built upon the IBM OpenCAPI, but CXL3 and CXL 4 have more speeds and will achieve the following:

    1- Enabling the Interconnection between IBM LinuxONE and Exa scale AI Data Centers based on Nvidia DGX H100 based on Nvidia H100 GPUs and Intel Xeon Scalable Processor (Now, Xeon Scalable Processor 4 supports CXL 1.1 , but in the future versions they will support CXL 2.0 or CXL 3.0).

    2- Enabling the interconnection between the IBM Z LinuxONE and the future versions of IBM Power Systems, the interconnection can achieve the Memory Area Network, which will push the integration between the IBM z Linux ONE and IBM Power to the Next level of Future AI Data centers.

    3- Enabling the IBM z LinuxONE interconnections with the CXL 3.0 or CXL 4.0 Networking Hierarchical Switches, which enable the CXL Devices, e.g. FPGA Devices, Memory Devices, Data Storage Devices and other futuristic devices.
