Cisco: __ Support vSphere platform for VFIO / DPDK (with SRIOV)

1. Master Node:

   a) 3 master nodes running as VM on vSphere environment.

1. Worker Node:

   a) 2 worker nodes running as VM on vSphere environment.

   b) 1 worker node running as BareMetal UCS server with XL710 SRIOV card, provisioned on vSphere environment.

1. Packages:

   a) OpenShift 4.9

   b) Red Hat Enterprise Linux CoreOS release 4.9 on all master/worker nodes

1. CNI:

   a) Multus with SRIOV plugin.

   b) “vfio-pci” as deviceType in “SriovNetworkNodePolicy” yaml file.

1. Application:

   a) DPDK pod which binds to VF’s PCI address which is created from the PF’s during “SriovNetworkNodePolicy” and “SriovNetwork”deployment.

•  Why is this important:  

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

           Also, we were using SRIOv-based deployment in our CNF to increase the performance.

•  Dependencies (internal and external)

Cisco: Vmware Cluster Setup with VFIO and SRIOv VF on worker nodes

• Any End-Customers Requesting Feature/Functionality

                [Cisco] SRIOv is required to get more perf numbers w.r.t underlying hardware (XL710/XL810 cards). Also 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] Evauled SRIOv with CNI only in the bare-metal nodes. However, we need to validate the SRIOv on ShiftOnVM with VFIO.

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

Cisco: Yes. Can participate in beta testing.
