Introduction

Provisioning Red Hat OCP cluster for running RDMA and DPDK-based workloads over VMware vSphere environment may prove to be challenging. Proper design, software and hardware components selection could be a gating task toward a successful deployment.

This guide provides step-by-step instructions on how to deploy a Red Hat OCP cluster by using OCP Assisted Installer on a single vSphere cluster, including technology overview, design, components selection and deployment steps. The Assisted Installer is a user-friendly installation solution offered on the Red Hat Hybrid Cloud Console . The Assisted Installer focuses on bare metal and vSphere infrastructures.

VMware’s vSANoRDMA is now fully qualified, and available as of the ESXi 7.0 U2 release, making it ready for deployments.

In this document, we will be using the NVIDIA Network Operator, which is responsible for deploying and configuring, with a Host Device Network mode. This allows to run RDMA and DPDK workloads on an OCP Cluster Worker Node.

Key Components and Technologies

NVIDIA Spectrum Ethernet Switches
Flexible form-factors with 16 to 128 physical ports, supporting 1GbE through 400GbE speeds.
Based on a ground-breaking silicon technology optimized for performance and scalability, NVIDIA Spectrum switches are ideal for building high-performance, cost-effective, and efficient Cloud Data Center Networks, Ethernet Storage Fabric, and Deep Learning Interconnects.
NVIDIA combines the benefits of NVIDIA Spectrum^™ switches, based on an industry-leading application-specific integrated circuit (ASIC) technology, with a wide variety of modern network operating system choices, including NVIDIA Cumulus^® Linux , SONiC and NVIDIA Onyx^®.

NVIDIA Cumulus Linux
NVIDIA® Cumulus® Linux is the industry's most innovative open network operating system that allows you to automate, customize, and scale your data center network like no other.

NVIDIA ConnectX SmartNICs
10/25/40/50/100/200 and 400G Ethernet Network Adapters
The industry-leading NVIDIA® ConnectX® family of smart network interface cards (SmartNICs) offer advanced hardware offloads and accelerations.
NVIDIA Ethernet adapters enable the highest ROI and lowest Total Cost of Ownership for hyperscale, public and private clouds, storage, machine learning, AI, big data, and telco platforms.

NVIDIA LinkX Cables
The NVIDIA® LinkX® product family of cables and transceivers provides the industry’s most complete line of 10, 25, 40, 50, 100, 200, and 400GbE in Ethernet and 100, 200 and 400Gb/s InfiniBand products for Cloud, HPC, hyperscale, Enterprise, telco, storage and artificial intelligence, data center applications.

RDMA
RDMA is a technology that allows computers in a network to exchange data without involving the processor, cache or operating system of either computer.
Like locally based DMA, RDMA improves throughput and performance and frees up compute resources.

RDMA over Converged Ethernet
( RoCE ) or InfiniBand over Ethernet ( IBoE ) ^[1] is a network protocol that allows remote direct memory access (RDMA) over an Ethernet network. It does this by encapsulating an InfiniBand (IB) transport packet over Ethernet.

Red Hat® OpenShift Container Platform® is an enterprise-ready Kubernetes container platform built for an open hybrid cloud strategy. It provides a consistent application platform to manage hybrid cloud, multicloud, and edge deployments.

NVIDIA Network Operator
An analog to the NVIDIA GPU Operator, the NVIDIA Network Operator simplifies scale-out network design for Kubernetes by automating aspects of network deployment and configuration that would otherwise require manual work. It loads the required drivers, libraries, device plugins, and CNIs on any cluster node with an NVIDIA network interface. Paired with the NVIDIA GPU Operator, the Network Operator enables GPUDirect RDMA, a key technology that accelerates cloud-native AI workloads by orders of magnitude. The NVIDIA Network Operator uses Kubernetes CRD and the Operator Framework to provision the host software needed for enabling accelerated networking.

Logical Design

The described setup uses one vSphere cluster that includes 4 ESXi servers connected to two NVIDIA® Spectrum® SN2010 Ethernet switches (Management, Ingress and Egress traffic), and one NVIDIA® Spectrum® SN2100 Ethernet switch (High speed vSAN, RDMA and DPDK traffic).

vCenter, Infra Node and Router VMs will be placed on the same cluster.

Warning

For production design, it is recommended to place a vCenter, Infra Node and Router VMs in a separate management cluster. This recommendation applies for VMware Validated Design (VVD) and VMware Cloud Foundation (VCF), which is based on VVD.

Network Design

The Cluster networking is configured with the following networks:

Corporate (Management) Network (VLAN 1610 - 192.168.1.x/24)
The network responsible for connectivity between the ESXi VMkernel Management interface, vCenter and other Management VMs.

Warning

DHCP and DNS services are required. The components installation and configuration are not covered in this guide.
vMotion Network (VLAN 1611 – 192.168.11.0/24)
This is where the ESXi vMotion VMkernel interfaces will reside.
OCP Network (VLAN 1677 - 192.168.77.0/24) – OpenShift Management network.
vSAN Network (VLAN 1630 – 192.168.30.0/24)
This is where the ESXi vSAN VMkernel interfaces will reside.
RDMA Network (VLAN 1631 – 192.168.3.0/24)
This is where the ESXi vSAN VMkernel interfaces will reside.

ESXi Host and vSphere Cluster Configuration

Prerequisites

Host BIOS
Verify that an SR-IOV supported server platform is being used and review the BIOS settings in the server platform vendor documentation to enable SR-IOV in the BIOS.
Verify that VT-d/IOMMU is enabled in the BIOS.
Physical server configuration
All ESXi servers must have the same PCIe placement for the NIC and expose the same interface name.
Experience with Kubernetes/OpenShift
Familiarization with the Kubernetes Cluster architecture is essential.
Privileges
Verify that you have an account privilege to read and create the required resources. Using an account that has global administrative privileges is the simplest way to access all the necessary permissions on the cluster. For more information, see Chapter 20. Installing on vSphere OpenShift Container Platform Container Platform 4.10 | Red Hat Customer Portal
Verify that NTP is configured and works properly in your environment.

Sample:

Create and configure a VMware vSAN RDMA cluster by using the following document - RDG: VMware vSAN over RoCE on VMware vSphere 7.0 U3.
Enable SR-IOV on an ESXi host
NVIDIA Network Operator leverages Kubernetes CRDs and Operator SDK to manage networking-related components to enable fast networking and RDMA for workloads in the OCP cluster. The fast network is a secondary network of the K8s cluster for applications that require high bandwidth or low latency.
In OCP Cluster it is possible to use Dynamic DirectPath I/O to assign a multiple PCI passthrough or SR-IOV devices to a Kubernetes Workload VM.
To make it work, enable SR-IOV capability on a ConnectX-6 Dx network adapter.
To Enable SR-IOV:
1. Launch the vSphere Web Client , and connect to a vCenter Server instance.
2. Navigate to a an ESXi host, and select Configure → Hardware → PCI Devices. Click on ALL PCI DEVICES. Click on Filter.
3. Type Mellanox and click on Vendor Name.
4. Select a ConnectX-6 Dx NIC.
5. Click on CONFIGURE SR-IOV.
6. Enable SR-IOV, and set the number of Virtual functions (VF). Click OK.
7. Click on PASSTHROUGH-ENABLED DEVICES to verify that 8 VFs were enabled.

Create 6 VMs for 3 Control and 3 Worker OpenShift Clusters with the following configuration:

On the Customize hardware tab, click VM Options → Advanced.
- Click Boot Options. Set the Boot Delay to 9999 milliseconds.
- Scroll down and click Edit Configuration. On the Configuration Parameters window, click Add Configuration Params. Define the following parameter name and value:
  - disk.EnableUUID: Specify TRUE.
    
    Click OK twice for Control VMs.
    For worker VM, click OK. Go back to the Virtual Hardware tab and add an additional SR-IOV Network Adapter by clicking on ADD NEW DEVICE and selecting Network Adapter.
    
    On New Network click on Browse...
    
    Select an RDMA network port group. Click OK.
    
    Open New Network and select Adapter Type: SR-IOV passthrough and Physical Function (for example, vmnic4 was configured previously with VFs). Click OK.

OCP Cluster Installation

Infra node Prerequisites

DHCP and DNS services are required for OCP installation. In this case, an Infra Node is used to run the services.

An additional ntp-servers configuration is required for a DHCP service on an OCP management network.

Warning

The components installation and configuration are not covered in this guide.
For more information, see Networking requirements for user-provisioned infrastructure.

The OCP cluster installation requires two VIP addresses:

The API address is used to access the cluster API.
The Ingress address is used for cluster ingress traffic.

These IP addresses must be provided to the installation program when installing the OCP cluster.
In our environment, we use the following IPs and DNS records:

Component	IP	Record	Description
Kubernetes API	192.168.77.210	api.ocp4.vwd.clx	A DNS A/AAAA or CNAME record, and a DNS PTR record, to identify the API load balancer. These records must be resolvable by both clients external to the cluster and from all the nodes within the cluster.
Ingress	192.168.77.211	*.apps.ocp4.vwd.clx	A wildcard DNS A/AAAA or CNAME record that refers to the application ingress load balancer. The application ingress load balancer targets the machines that run the Ingress Controller PODs. The Ingress Controller PODs run on the compute machines by default. These records must be resolvable by both clients external to the cluster and from all the nodes within the cluster. For example, `console-openshift-console.apps.ocp4.vwd.clx` is used as a wildcard route to the OCP console.
control01	192.168.77.11	control01.ocp4.vwd.clx	DNS A/AAAA or CNAME records and DNS PTR records to identify each machine for the control plane nodes. These records must be resolvable by the nodes within the cluster.
control02	192.168.77.12	control02.ocp4.vwd.clx	DNS A/AAAA or CNAME records and DNS PTR records to identify each machine for the control plane nodes. These records must be resolvable by the nodes within the cluster.
control03	192.168.77.13	control03.ocp4.vwd.clx	DNS A/AAAA or CNAME records and DNS PTR records to identify each machine for the control plane nodes. These records must be resolvable by the nodes within the cluster.
worker01	192.168.77.21	worker01.ocp4.vwd.clx	DNS A/AAAA or CNAME records and DNS PTR records to identify each machine for the worker nodes. These records must be resolvable by the nodes within the cluster.
worker02	192.168.77.22	worker02.ocp4.vwd.clx	DNS A/AAAA or CNAME records and DNS PTR records to identify each machine for the worker nodes. These records must be resolvable by the nodes within the cluster.
worker03	192.168.77.23	worker03.ocp4.vwd.clx	DNS A/AAAA or CNAME records and DNS PTR records to identify each machine for the worker nodes. These records must be resolvable by the nodes within the cluster.

This document describes OCP on-premises VMs installation using the Assisted Installer.

Follow the steps outlined in the section to install OpenShift on vSphere.

Open a web browser on Infra Node (in this case, AlmaLinux with UI is used), connect the Red Hat Hybrid Cloud site and log into the console with your credentials.
Using the left menu bar, select OpenShift:
Click on Create Cluster.
Select Datacenter and scroll down the window.
Select vSphere.
Select the Assisted Installer installation type.
In the Cluster details open window, provide Cluster Name and Base Domain. From the drop list, select the OpenShift version that you wish to install, and click on Next.
Example:
In the Host discovery window, click on Add hosts.
In the Add hosts window, select the Full Image file option. Generate, copy and paste an SSH public key (the key was generated in Infra Node in our case), a nd click on Generate Discovery ISO.
Examples:
In the opened window, click on Download Discovery ISO.
Login to the vCenter.
Navigate to your control01 VM.
Attach the Download Discovery ISO to your VM.
Launch Remote Console.
And Power On a VM.
Click ESC, and select CD-ROM Drive in the Boot Menu.
Click Enter.
Repeat Steps 12-17 for 5 additional VMs .
Go back to the RedHat Hybrid Cloud Console web page. After 1-2 minutes, you will be able to see all 6 hosts in "Ready" status.
Review the CPU, Memory and Disk hosts configuration.
Select Role for each H ost and click Next .
Example:
In the Networking opened window, provide the Machine network, API IP and Ingress IP. Click Next.
Example:
Review the configuration and click on Install cluster.

The OCP Installation process will start and will take approximately 30 minutes.
Once the installation process is complete, you will be able to Download the kubeconfig file.

Copy the file on your Infra Node to the /root/.kube/config file.

[oot@sl01lw01depl ~]# export KUBECONFIG=/root/.kube/config

To connect to the installed cluster, use the following provided information:

To verify that the OCP cluster is installed properly, open the Infra Node console and open a web browser with the provided Web Console URL, Username and Password.

Make sure that the Cluster Status is ok.

Using the left menu bar, expand the Compute section and select the Nodes Status. 

Click on each node to see that all PODs on the node are running without errors.

To check the cluster status from the ssh console:

Go to the Infra Node ssh console, and run the following command to see the nodes status:

Installing the Node Feature Discovery (NFD) Operator

The OpenShift Node Feature Discovery (NFD) manages the detection of hardware features and their configuration in the OpenShift Container Platform. The NFD labels the host with node-specific attributes. Therefore, the NFD is a prerequisite for the NVIDIA GPU Operator. As a cluster administrator, you can install the NFD Operator using the Red Hat OperatorHub catalog in the OpenShift Container Platform web console.

Using the left menu bar, expand the Operators section, and select the OperatorHub.
Use the search bar to search for the Node Feature Discovery. Two items should be found as results.
Select the operator that is tagged as the RedHat operator. This is the version supported by Red Hat.
Click Install.
The next menu allows you to determine how and where the operator will be installed. You would rarely have to change any of these options.
Click Install to continue with the defaults.
Wait while the NFD operator is being installed. Once you see the “Installed operator - ready for use” status, click View Operator . Notice that you are now in the openshift-nfd project that was created as part of the operator installation.
Click the Create Instance button to create a new NFD object.
The next menu provides options to configure how the NFD operator will scan your cluster. For the NFD operator, you would rarely have to change any of the default settings. Click Create to instantiate the NFD resource on your cluster.
You will be able to see the installation progress in the Infra Node ssh console. It can take 5 minutes for the NFD installation.
In the horizontal menu bar, select NodeFeatureDiscovery . You should be able to see one listed instance titled nfd-instance . Wait for the status to show that the deployment is finished.

Enabling a Cluster-wide Entitlement

The NVIDIA Network Operator deploys several PODs that manage and enable NVIDIA High Speed Networking for use in the OpenShift Container Platform. Some of these PODs require packages that are not available by default in the Universal Base Image (UBI) that the OpenShift Container Platform uses. To make packages available, you must enable cluster-wide entitled container builds in OpenShift. To do that, f ollow the instructions in Enabling a Cluster-wide Entitlement .

By running oc get mcp/worker command. You can see MachineConfigPool object monitor that the MCP is updated, not updating or degraded, so all the MachineConfig resources have been successfully applied to the nodes and you can proceed to validate the cluster.

Installing the NVIDIA Network Operator

Please see the below steps for Network Operator deployment using Web UI.

Warning

Before starting, create a namespace for the Network Operator Resources by running [root@sl01lw01depl ocp4-helpernode]# oc create ns nvidia-operator-resources

Using the left menu bar, expand the Operators section, and select the OperatorHub.
Use the search bar to search for NVIDIA. Two items should be found.
Select the NVIDIA Network Operator .
Click Install.
The next menu allows you to define how and where the operator will be installed. You would rarely have to change any of these options.
Click Install to continue with the default values.
Wait while the NVIDIA Network operator is being installed. Once you see the “Installed operator - ready for use” status, click View Operator .
Click the Create Instance button to create a new NicClusterPolicy object.

Click on YAML view, and change to the following:
