Hi, be carefull about your SQL server capacity. If this serveur is too small, your SEPM server will be slow.
As an exemple, I manage about 50000 clients, my SQL server got 16 Go Ram, 2 Xeon 2.16 Ghz with 4 core each. This configuration let SQL to be efficient, with enough RAM to load half the database in memory and the 8 Core are enought sized to compute large SQL request, in the morning when all clients boots up.
Cheers.
