Requirements for dual-stack (IPv4/IPv6) CTA

Hi all,

In the run up to getting our CTA instance up and running on real hardware, I wanted to double check I wasn’t missing anything for the IPv6 side of things.

As far as I can tell, a dual-stack CTA instance only needs to have EOS nodes (MGMs + FSTs) accessible over IPv6, and there is no requirement for any of the CTA nodes to be dual-stack. Have I missed something?


Hi Tom,

You are correct : CTA communicates directly with the MGMs and FSTs, and the CTA frontend/tape servers don’t need to be exposed to the outside world.

The only other channel which communicates directly with the frontend is the cta-admin tool, but it is envisaged that this will run on the local network.
