Adding Virtual Appliances for the Compute Express Link ( CXL Virtual Switch Appliance) to the IBM LinuxONE

Thank you for submitting this request. IBM has evaluated the request, and has unfortunately determined that it can not be implemented at this time or does not align with the current multi-year strategy. This request may be resubmitted for consideration after 12 months from the date of decline. The request submitter will automatically be notified by email when the request qualifies for reconsideration and resubmission.

Hi,

Kindly, review the attached PDF File which includes the Use Cases that you asked about.

Please Note, my ideas are concentrated on the Heterogeneous computing including IBM Power , IBM Z, IBM LinuxONE, Intel IPU, Intel Servers, Intel FPGA , Nvidia DGX, Nvidia DPU, Nvidia GPU, AMD Servers, Xilinx FPGA and other future Systems from other companies.

I will be very pleased to answer your questions.

Thanks, with kindest regards,

Kindly, The below Article from the below document:

Red Hat OpenShift Container Platform on IBM Z and IBM LinuxONE

As in the following Hyperlink

https://public.dhe.ibm.com/software/dw/linux390/docu/RHOCP-reference-architecture.pdf

4.2 Networking

In an RHOCP environment, planning of the network is very important given the fact that with IBM Z and IBM LinuxONE you have different choices and combinations for the RHOCP network. Each RHOCP node can have one or more network interfaces. The network design is dependent on the isolation requirements and integration architecture with other workloads Depending on the implementation and hypervisor, you can use the following network options:

• HiperSockets networks, which are internal IBM Z and LinuxONE networks. They do not require any network cards. You can define multiple instances in one machine.

• OSA (Open System Adapter) cards that can be shared and at the same time can be bounded for enhancing the network bandwidth and build an HA network.

• RoCE cards which are like the OSA cards, being able to be shared as well and run different protocols.

• Depending on the hypervisor you can use virtual switches in combination with the network capabilities of IBM Z and LinuxONE mentioned above.

About the forth paragraph:

• Depending on the hypervisor you can use virtual switches in combination with the network capabilities of IBM Z and LinuxONE mentioned above.
