EAServer Clustering requirements

Hi,

We have an existing EAServer 6.3.1 for Windows, and we need to set up EAServer Clustering. We already have Primary Server and we will planning to add another two (2) for participating server.

My concern is

1. Can we have different specification for another two (2) (lower or higher specs) or it is required to be the same specification like the existing server?

2. Do you have any reference or document regarding this?

Thank you very much! 😊
