How to provision better storage and enhance cluster deployments on Red Hat OpenShift Service on AWS with Amazon FSx for NetApp ONTAP

As developers continue to use platforms such as Kubernetes to deploy applications, many of these deployments could benefit from a persistent, shared storage layer. While Red Hat® OpenShift® Service on AWS (ROSA) clusters can use locally attached Amazon Elastic Block Store (EBS) volumes, there is another scalable solution: Amazon FSx for NetApp ONTAP (FSxN).  Internet Small Computer System Interface (iSCSI) in FSxN offers several benefits for managing and accessing storage—including cost savings, flexible scaling, and ease of use.

In this learning path, we’ll show you how to install Amazon FSx for NetApp ONTAP (FSxN) on AWS and use it to provision storage for containers and virtual machines running on ROSA clusters. We’ll create an FSxN file system within Red Hat’s virtual private cloud on Amazon and then install and configure Trident 25.02 in the ROSA cluster—allowing all of the subnets of this virtual private cloud to connect to the file system (see Figure 1). Finally, we’ll walk you through how to create container applications and virtual machines on ROSA clusters using iSCSI volumes.

Figure 1. This diagram shows the Red Hat OpenShift Service on AWS Hosted Control Planes cluster deployed in multiple availability zones. ROSA cluster primary and infrastructure nodes are in Red Hat’s virtual private cloud on Amazon, while the worker nodes are in a virtual private cloud in the customer's account.
