@Ahmed_Sammoud go to developer.redhat.com click the "Join Red Hat Developer" and request a subscription and then you can download the RHEL server DVD isos from access.redhat.com form the download page.
I looked at this thread and found that there is some confission between RHLC and RHA. I would like to post some clarification here
RHA is a Red Hat initiative for budding linux enthusiasits. This program offers seperate courses and Red Hat lab images that can be downloaded from gilmore and can be used for practising the lab exercises..
RHLC is Red Hat Learning Community that gives a single platfrom for all learners to interact with the community, share their ideas, post questions, help their peers etc. This community has Red Hat moderators who can participate in the discussion if needed.
I guess this clears the confission.
My confusion is between SKU RH2501844
|Red Hat Enterprise Linux Academic Site Subscription with Smart Management, Premium (Server, Desktop, Workstation, POWER, HPC, per FTE)|
(some called it RHA too)
and RHA as described by you.
