Using the Deployment Reference

The Deployment Reference is the starting point for any MAS 9 on OpenShift engagement. It covers the full solution from infrastructure to application layer.

Sections covered:
1. Solution overview — stack diagram and the role of each layer from infrastructure through application
2. Architecture — control plane, infrastructure, and worker node layout; network topology; storage tiers
3. OpenShift platform requirements — node counts, CPU/memory per role, networking, DNS, load balancers, storage network
4. MAS application requirements — per-application resource profiles for Manage, Monitor, Health, Predict, Visual Inspection, and Assist
5. NetApp Trident — CSI driver role, access mode matrix, backend types (NAS/SAN/NVMe), StorageClass design
6. Environment variants — guidance specific to Bare Metal, VMware, AWS FSx for ONTAP, and Air-Gapped deployments
7. Installation sequence — the full 8-phase phased delivery from infrastructure through application go-live
8. Day-2 operations — backup, upgrade paths, scaling, monitoring, ONTAP maintenance
9. References — links to IBM, Red Hat, and NetApp documentation

Use the in-page anchors (section headings) to jump directly to a section. The document is designed to be read alongside the Pre-Deployment Checklist — each checklist phase maps to a section here.

Version assumptions: MAS Core 9.0.x, OpenShift 4.14–4.16, Trident 25.06.1+, ONTAP 9.12.1+. Always verify against vendor interoperability matrices before procurement.
