Infrastructure Requirements Designer

You can customize the kubernetes cluster with custom infrastructure requirements like custom packages, network adapters, kernels, and so on, using infrastructure designer. These customizations are available only for CNF components.

You can use the VMware Telco Cloud Automation to customize the infrastructure requirements of the node pools. You can define these customizations through user interface and the system adds these customizations to the corresponding TOSCA file. For more details on the TOSCA components, see TOSCA Components.

For more details, see CTX Per Dev. For more details on Enhanced Datapath settings, see Configuration to Support Enhanced Data Path Support.
     Note: When you select Target Driver, the system automatically adds the required DPDK in Kernel Modules and dependent custom packages in the Custom Packages.
   • PCI Pass Through - Click Add to enter the PTP or PCI Devices.
     Note: When you add a PCI Pass Through device, the system automatically adds the required Linux-rt in Kernel Type, DPDK in Kernel Modules, and dependent custom packages in the Custom Packages.
     • For the PTP devices, add the following information.
       Note:

       • To use the PTP PHC services, enable PCI passthrough on PF0 on ESXi server when the E810 card is configured with multiple PF groups.
       • To use the PTP VF services, disable the PCI passthrough on PF0 and enable the SRIOV on both the PFs. E810 card supports 1 VF as PTP and the other VF serves as SRIOV VF NICs for network traffic.
       1. Device Type - You can select to add a PTP device or a NIC device. To use a physical device, select NIC. To use a virtual device, select PTP from the drop-down menu.
          Note: To upgrade the device type from PTP PF to PTP VF, delete the existing PTP PF device and add the new PTP VF device. Do not change the device type from NIC to PTP directly in the CSAR file.
       2. Shared Across NUMA - Select the button to enable or disable sharing of the devices across NUMA.
          Note: Shared Across NUMA is applicable only when NUMA Alignments is enabled.
       3. PF Group - Enter the name of the PF group for which you want to PCI Pass Through device.
       4. Enter the details for phc2sys and ptp4l files.
          • Source - To provide input through file, select File from the drop-down menu. To provide input during network function instantiation, select Input from the drop-down menu.
            Note: To select File from the Source menu, you must first upload the required file in Artifacts folder available under the Resources tab.
          • Content - Name of the file. The value is automatically displayed based on the Source value.
       5. Click Add to confirm.
     • For the PCI Device, add the following information.
       Note:

       • Before adding the ACC100 Adapter PCI device, ensure the ACC100 Adapter is enabled in the VMware ESXI server. For details, see Configuring the ESXI Driver for the Intel vRAN Accelerator ACC100 Adapter.
       • You can add the ACC100 Adapter on the workload clusters with kubernetes version 1.20.5, 1.19.9, or 1.18.17. For workload cluster upgrade, see Upgrade Management Kubernetes Cluster Version.
       1. Shared Across NUMA - Select the button to enable or disable sharing of the devices across NUMA.

       2. Enter the name of the resource in Resource Name.
       3. Select the Target Driver from the drop-down menu.
          Note: Based on the Target driver, the system automatically adds the required Linux in Kernel Type, pciutils and DPDK modules.
