Hi all,  
I have a server with 1.5 TB memory.  
I can either use it with a single ES process, or launch few separate  
instances (using either VM, docker, or just different ports on the same  
server OS).

What will be a reasonable number of instances for such a server ?

Thanks,  
Tzahi

It's definitely reasonable to run multiple instances per physical here.
