Which one to choose? RHEL HA Add-On or RHEL RS Add-On?

Latest response

Just wanted to request for information on what specific things do I need to look out for to determine if my client needs HA or RS Addons.

Which one do I need for A/P clusters and which one do I need for HA clusters?

Also, may I please know if there's an in-depth comparison between the two?

Thank you!

Hi,

You may need both subscriptions. If you've plans of using 'gfs2' (shared storage) then you would certainly need to resilient storage subscription and HA would also required, because all main cluster components would come from this channel.
