Lync 2013 Deployment Requirements - One Server?

Question

I have an organization that has an offsite Exchange Server 2010, and Windows Server 2008 R2 Domain Controller (for the Exchange Server).
I am trying to figure out what we need for hardware and Windows Server software to implement Lync 2013.  I understand that Lync 2013 cannot be put on the same server as the Exchange Server.  Can Lync 2013 be put on one Windows server?

Depends. Without knowing a lot about your environment (i.e users, HA requirements) ideally you'd have two. One as a Lync Standard Edition server (which can support up to 5000 users for Front End Services and Back-End database - but won't have HA) and one
as an Lync Edge server (for outside connectivity - also won't have HA)
Standard Edition will use SQL express as its database and automatically install it on the single server.
As for operating system Windows 2008 R2 or above.
As for hardware you can use this as a guide: http://technet.microsoft.com/en-us/library/gg398835.aspx and use the Lync Capacity planning tool http://www.microsoft.com/en-us/download/details.aspx?id=36828
How many users do you have? (for example the first link has 32GB as recommended memory for a Front End, but if you don't have many users you can use less than that - and the Cap Planner will reflect that)
