I want to deploy a iDataPlex cluster but using only free software with xCat. The xCat start guide uses Red Hat Enterprise Linux 5 in the management node.
What's the best free distro to install instead of RHEL in the management node?
I looking for the most compatible distro with RHEL. Maybe the best options should be Fedora or Centos.
-  Fedora is the upstream of RHEL
-  Centos is a community distro using RHEL sources.
