   == Specific application storage recommendations
  
positive.code: 
  * The preferred storage technology is object storage. The storage technology must support RWX access mode and must ensure read-after-write consistency.
  * File storage and block storage are not recommended for a scaled/HA {product-title} registry cluster deployment with production workloads.
  * All NAS storage are not recommended for {product-title} Registry cluster
  deployment with production workloads.

  ====
  Testing shows issues with using the NFS server on RHEL as storage backend for
  core services. This includes the OpenShift Container Registry and Quay,
  Prometheus for monitoring storage, and Elasticsearch for logging storage.
  Therefore, using RHEL NFS to back PVs used by core services is not recommended.
  
  Other NFS implementations on the marketplace might not have these issues.
  Contact the individual NFS implementation vendor for more information on any
  testing that was possibly completed against these {product-title} core
  components.
