Support real HA Cluster with GFS and multiple Locations
Dear RedHat,
I was surprised to learn the Redhat doesn't have a real High Availability solution.
RHEL with HA (Cluter) and Resilient Storage (GFS) - Add on are only supported if it is in the same data center aka. not-stretched cluster.
High Availability is the elimination of single point of failures and everything in one data center is exactly that.
Especially because I don't see a technical reason for that.
It would be nice to see RHEL7 playing with the big boys!

Hopefully this KBASE will help explain supportability of stretch clusters:
https://access.redhat.com/kb/docs/DOC-61218
"Stretch clusters (ie. clusters in separate physical locations connected over a long distance) require special reviews to ensure that their design is within the limits of Red Hat Cluster Suite."
Therefore, full support for a stretch cluster would first need to be reviewed via an Architecture Review by Red Hat Support and Red Hat Engineering.
Hope this helps!
