Has anyone here gone through the process of properly sizing the hardware requirements for deploying the IFS EAM solution?

I’m currently working with a client that operates a single cargo ship and will have around 20 concurrent users accessing the system. I’m looking for guidance or best practices on how to specify the right server resources (CPU, memory, and especially storage capacity) for this type of setup.

Any references, calculation guidelines, or examples from similar implementations would be greatly appreciated.
