Is NFS is recommened in production for 3PAR on Openshift Container Platform?

Issue

• NFS export from server instead of fileshare from storage array, is it possible, is it recommended?
• OpenShift storage requirement of a “NFS export” is from the local machine and NOT a NFS file share from the 3PAR array, is that correct? Referencing this information
• ur 3PAR array is able to share luns with “groups” of servers configured on the 3PAR array.
  Referencing the information below, will we be able to use iSCSI and disk sharing instead of a NFS mount? From this link
• A PersistentVolume object is a storage resource in an OpenShift cluster. Storage is provisioned by an administrator by creating PersistentVolume objects from sources such as GCE Persistent Disks, AWS Elastic Block Stores (EBS), and NFS mounts.
• Persistent volume plug-ins other than the supported NFS plug-in, such as AWS Elastic Block Stores (EBS), GCE Persistent Disks, GlusterFS, iSCSI, and RADOS (Ceph), are currently in Technology Preview. The Administrator Guide provides instructions on provisioning an OpenShift cluster with persistent storage using NFS
