Master Host in multi-host HANA system

Hi there,

I have a rookie question:

I got confused when reading about HANA multi-host systems. So what exactly is a master host?

I know there is a worker and standby hosts, but in the same document they just talk about master host without giving any definition (I am using "SAP HANA Administration guide"). Is it the host that contains the system database in master configuration?

Thanks!
