Do I need to get a seperate server for Lync 2010? We have about 50 end-users most will be using the system for IM and perhaps the PBX integration later on.
Could I install it on the same server as our 1) Exchange Box (12 GB of RAM, dual socket quad xeons, 10k raid 1 OS, 15k raid 5 data + external mailfoundry spam box/appliance)? Otherwise, I could install it on our grossly under utilized 2) Dynamics GP server. However, I'd have to be certain it would not interfere (such as crash) the server with our finance server. Finally, perhaps I could put it on a 3) smaller BES/MS SCCM/WSUS (configuration manager) server.
Which server should/could I put it on: 1) exchange, 2) Dynamics GP (needs to be absolutely stable), 3) SCCM/WSUS/Blackberry Enterprice Server
Initially, I'm going to use it for IM funtionality only but I'd like to integrate it with our PBX (samsung officeserv 7200). If the Lync Server goes down do all our phones go down even though they still use the PBX?
How is the performance impacted client-side?
Is the intial configuration difficult? More or less difficult than System Center Configuration Manager?
The main pre-implementation/sales question is do I need another server though
