Distribution (Segregation) on Linux CentOS

Hi ,

we are in middle of distribution (segregation) from 1 server to 4 servers (see the architecture bellow).

We firstly distributed on windows using Appian 18.1 , but from support we were advised to move on Linux environment.

We have already installed Appian on CentOS with dedicated HW (disk space) that full fill our requirements (each server has 500 GB spaces ) , but now we are in wondering if we are on the best recommendation approach .

Should we share a space on a storage or only share the folded between servers ?
