SEPM desing for large environment
I want suggestion from all of forum friends about the design of SEPM for large environment. I have a scenario for up to 2 million clients e.g., north , south, east and west part of globe or country, in each part there would be so many sites , where the number of client would be apprx 200-300. So for these total number of client would be approx 2 million total. There would be good WAN connectivity between sites.
So please suggest me the what type of architecture would be for these number of clients and how may SEPM servers, SQL Server, Failover server, or Replication servers would be reqd. Either single SEPM server would be sufficient for these clients with failover server, SQL server would be on different server or installed in both SEPM, on primary SEPM or failover SEPM. If I installed SQL on different server, in that case I also require additional SQL server to consider in case of fail of SQL server, If I install SQL on both SEPM , first will be primary SEPM and second will be failover which will define on client priority list on SEPM and with replication partner , if one goes down automatically clients will move to failover SEPM so downtime would be Zero.
to update clients on site I will configure GUP on SEPM for that site which would be any one Sever of site which will act as GUP, and to update central site both SEPM I will have two scenario, First I will update SEPM through Symantec Live Update and Second it will update through internal LUA also so for LUA I require one more Server for LUA. Now as I assume total number of server would be only 3 and If I install SQL separately then 2 more server reqd for SQL with failover of SQL.
In that case to manage these millions of clients I require only 2 Servers for SEPM 1 Server of LUA and 2 SQL server for Database. If SQL on both SEPM then only 3 Servers enough for design.
I have describes the scenario above , please suggest me the best design for millions of clients, the update method of site clients, either GUP or through LUA? sites under these 4 region how many groups can be added? I will welcome suggestions all of you.
I have gone through the documents also for SEPM design,
