Mike, my only point is if we can't make failover of repository server then what if our repository server crash ? If we keep repository and application on central node at least failover node will serve the application.

What is the concept of creating repository application somewhere else

Rohit, You can spread Qlik Components across different boxes to achieve a better resilience or scaling out to address increasing work load except the Repository and the share folder. In an HA configuration you need to avoid any single point of failure for this reason you want to get them out of any Qlik nodes and rely on different solutions e.g.

1) SAN (or NAS SMB 3 from Sept 2017) using some kind of RAID for the sharing folder

2) Postgres HA for the Repository 

3) Rely on virtual solution such as VMWare HA


Hope this answers your question

Vincenzo,

Thank you for suggestion!

I will check with my IT/Infrastructure team if we can setup one of these solutions for our PROD environment.
