Red Hat cluster suite subscription for RHEL 5 server ???
 

This is extract from Red Hat site.

Red Hat Cluster Suite and Global File Systems (GFS) are included in
Red Hat Enterprise Linux 5 Advanced Platform. They are still layered
offerings for Red Hat Enterprise Linux 3 and 4.


I want to ask if I am using Red Hat Enterprise Linux 5 server, not Advance platform, then what about cost for Clsuter suite,

Either I have to purchase its subscription for RHEL5 server, or it is free like it is free for Advance platform.

Red Hat Enterprise Linux Standard 1 Yr. 639 EUR
Red Hat Cluster Suite 1-9 1 Yr. 399 EUR (requires RHEL subscription)
Red Hat Global Filesystem 1 Yr. 1790 EUR
