I would recommend anyone going down that to route to take a *very* close 
look at what you get for the extended support. Not all of the OS is 
supported, with large chunks being moved to unsupported even if you pay 
for the extended support.

Consequently extended support is not suitable for HPC usage in my view, 
so start planning the upgrade now. It's not like you haven't had 10 
years notice.

If your GPFS is just a storage thing serving out on protocol nodes, 
upgrade one node at a time to RHEL7 and then repeat upgrading to GPFS 5. 
It's a relatively easy invisible to the users upgrade.

JAB.
