Windows Server 2012,Essentials and Ram

SUGGESTED

We currently run Sage 50 Quantum Accounting 2015.

We are looking into purchasing a New Server that will be running Windows Server 2012,Essentials...is Sage 50 Quantum Accounting 2015 compatible with this operating system?

Also, the system specs for a Sage 50 Multi-User Server environment is 2Gigs, will Sage 50 use more memory if it's available?

Thank you,

Mitch
