When deploying an application to an IBM Cloud OpenShift cluster that requires persistent storage across zones within a region, Portworx and Block Storage are viable options.

Portworx:This is a cloud-native storage solution designed for containerized environments like Kubernetes and OpenShift. Portworx provides highly available, scalable, and persistent storage that spans multiple zones within a region, ensuring data redundancy and availability.

Block Storage:IBM Cloud Block Storage provides persistent, high-performance storage that can be attached to virtual servers or containers. It is designed to offer cross-zone availability when configured with the necessary replication and redundancy settings.

Comparison with Other Options:

A (Kubernetes local volume storage):Not suitable for spanning multiple zones as it is tied to specific nodes.

B (Object Storage):Designed for storing large amounts of unstructured data; it is not typically used for persistent storage in Kubernetes.

D (NetApp on Tap):Primarily used for network-attached storage and might not be optimized for persistent storage across multiple zones in OpenShift.
