Nutanix Validated Design – AOS 6.5 with Red Hat OpenShift
Nutanix delivers the Validated Design – AOS 6.5 with Red Hat OpenShift as a bundled solution for running Red Hat OpenShift 4.12 that includes hardware, software, and services to accelerate and simplify the deployment and implementation process. This Validated Design features a full-stack solution for hybrid cloud deployments that integrates not only products like Nutanix NCI and NUS but also Red Hat OpenShift Platform Plus including Red Hat Quay and Advanced Cluster Manager.The Validated Design – AOS 6.5 with Red Hat OpenShift sizer reference scenario has the following features:
A baseline configuration for each Availability Zone is comprised of three clusters:
Management – 4-16 nodes cluster based on NX-3170-G8 for Prism Central, Active Directory, OpenShift Hub Cluster for Quay Registry and Advanced Cluster Manager, and any other management services including OpenShift Controlplane when using “large footprint” layout.
Workload – 4-16 nodes of NX-3170-G8 for Red Hat OpenShift Workloads.
Storage – 4-node cluster of NX-8155-G8 for Nutanix Files and Nutanix Objects.
A dedicated management cluster in each Availability Zone provides increased availability, security, operations, and performance. Management Cluster starts with 4 nodes and can be scaled up to 16 nodes if multiple “Large Footprint” OpenShift Clusters should be deployed.
The workload cluster has a defined maximum size of 16 nodes, which provides a reasonable maintenance window for rolling firmware and software upgrades. Smaller workload clusters can be deployed, but the maximum size should not exceed 16 nodes.
NVD defines two footprint for OpenShift Cluster Sizes:
- Small Footprint, OpenShift Controlplane shares same workload cluster as worker nodes, maximum of 25 worker nodes
- Large Footprint, OpenShift Controlplane runs in Management Cluster, worker nodes are running in workload cluster
Table: OpenShift Cluster Sizing: OCP Cluster (Workload) Small Footprint
| Component | Instances | Size |
| Control plane | 3 | 4 CPU cores, 16 GB |
| Infrastructure | 3 | 4 CPU cores, 16 GB |
| Worker | 2+ (max 25) | 4 CPU cores, 16 GB |
Table: OpenShift Cluster Sizing: OCP Cluster (Workload) Large Footprint
| Component | Instances | Size |
| Control plane | 3 | 16 CPU cores, 128 GB |
| Infrastructure | 3 | 16 CPU cores, 128 GB |
| Worker | 2+ (max 360) | Minimum 4 CPU cores, 16 GB |
- Services SKUs are not included in the Sizer reference scenarios. Review the BOM in the NVD appendix for the complete list of Services SKUs which should be included.
