Cisco: vSphere platform for VFIO / DPDK (without SRIOV)

1. Master Node:a) 3 master nodes running as VM on vSphere environment.
2. Worker Node:a) 3 worker nodes running as VM on vSphere environment.
3. Packages:a) OpenShift 4.9b) Red Hat Enterprise Linux CoreOS release 4.9 on all master/worker nodes
4. CNI:a) Multus with host-device plugin.b) “host-device” as type and “pciBusID” in “NetworkAttachmentDefinition” yaml file.
5. Application:a) DPDK pod which binds to available pci addresses with “vfio-pci” driver.

 Why is this important:  

Cisco: Our CNF uses DPDK and needs to support with VFIO driver combination for effective usage of CNF interfaces on host networking mode.

•  Dependencies (internal and external)

Cisco: Vmware Cluster Setup with VFIO provisioned on worker nodes

• Any End-Customers Requesting Feature/Functionality

                [Cisco] Multus CNI is required to minimize the interfaces ( from the host networking) from the node level.

• AnyAdditional Detailed Technical Requirements

Cisco: The VMware cluster should support DPDK-based applications run as CNF in VFIO

• Any alternate Options or Workarounds that have been evaluated and have the following Gaps:

[Cisco] Evaluated without VFIO mode in our CNF ( AF_PACKET mode in DPDK)

• Is RH Partner willing to help test use case/fixes:

Cisco: Yes. Can participate in beta testing
