[HELP] IT management Suite architecture

Hi,

I'm planning for and endpoint and server management solution. I'm a System Center Configuration Manager guy. As I have a set of desktop client that run Linux operating System, I'm considering using IT Management suite from Symantec.

How licensing is working for IT management Suite?

I have 3 sites. The headquaters contain more than 10000 users. Where can I find information for sizing and architecture the solution?

Thanks in advance

Regards,
