Supports internal Red Hat OpenShift Data Foundation clusters only.

An Internal cluster must meet both the storage device requirements and have a storage class that provides EBS storage via the aws-ebs provisioner.

OpenShift Data Foundation supports gp2-csi and gp3-csi drivers that were introduced by Amazon Web Services (AWS). These drivers offer better storage expansion capabilities and a reduced monthly price point (gp3-csi). You can now select the new drivers when selecting your storage class. In case a high throughput is required, gp3-csi is recommended to be used when deploying OpenShift Data Foundation.

If you need a high input/output operation per second (IOPS), the recommended EC2 instance types are D2 or D3.
