Hello

Recently a customer at my workplace bought two dell servers along with Pre-installed Linux
421-6928 Red Hat Enterprise Linux for HPC, 1 to 2 Socket, 1yr

I would like to know what the life-cycle of this RHEL HPC linux is and what Is the RHEL release for the pre-installed RHEL HPC OS by Dell? Is it based on, RHEL 5  6 or 7?

Thanks,

Aero
