hello, I want to know the hardware requirement for Sccm 2012 CAS in complex hierarchy for 70K users need really this suggested minimum configuration : Site details Suggested minimum configuration Central administration site with the Enterprise edition of SQL Server SQL Server is located on the site server computerThis configuration supports a hierarchy with up to 400,000 clients Note Database replication represents the largest processing load on the central administration site. 16 cores (Intel Xeon L5520 or comparable CPU)64 GB of RAM 1.5 TB of disk space for the operating system, Configuration Manager, SQL Server, and all database files. i don't think so, Can anyone help me to size a hardware CAS for 70k users....Separate SQL, Disk, RAM for each servers ? Microsoft support installation of this topology on VMs machines ?

Keep in mind that this forum is for ConfigMgr 2007 related questions only. CM12 ones should be posted to: http://innovation.connect.microsoft.com/discussions?ProjectName=configmgrbeta until the official Technet forums will be available. Thanks.Torsten Meringer | http://www.mssccmfaq.de

One major point here: there is no requirement for a CAS for 70,000 users. In fact, I strongly discourage a CAS unless you are managing 100,000+ systems (except for a few special cases).Jason | http://blog.configmgrftw.com | Twitter @JasonSandys
