GitLab storage HA solution in AWS

Hi,

I am trying to setup GitLab HA in AWS. Below is my rough idea.

GitLab frontend (primary) - Availability zone a

GitLab frontend (secondary) - Availability zone b

AWS RDS Aurora (psql) - Multizone (Availability zone a and b)

AWS elasticcache Redis - Multizone (Availability zone a and b)

Do you have any idea how to configure storage? GitLab says EFS is not recommended. I need HA (multizone) for storage also? Any help would be appreciated.

Thanks
