  • Hello,

    ==>So, basically if we take AD, DNS and DHCP out of the equation, only one-1 Server can accommodate all the roles?  Please, correct my understanding.
    Yes, you are right.

    ==>Just adding one more question:  And to have a HA of SCCM with minimum amount of servers, we would need a remote SQL/SQL Cluster as well as two-2 SCCM Servers holding all the roles each?  Please, correct my understanding.
    You're basically right. For really SCCM HA site server, besides a remote SQL/SQL Cluster as well as two SCCM Servers holding all the roles each(one active site server and one passive site server), it's also recommended that we build a remote content library and a remote SMS Provider.

  • Hi, 

    Yes, several site systems don't support multiple instances at a site or in the hierarchy. Please review the list:

    Asset intelligence synchronization point
    Endpoint protection point
    Enrollment point 
    Enrollment proxy point
    Fallback status point
    Service connection point

    For more details, please refer to:

  • Hello,

    Based on my experience, for small SCCM environment, only two servers are required.
    Roles for server1: AD,DNS and DHCP.
    Roles for server2: SQL server and all other roles for SCCM, such as Primary Site Sever,DP,MP,SUP etc.

    Please refer to this guidance: SCCM 1802 install guide

    As shown below in my environment. It is now functioning well. DC01 is server1(AD,DNS and DHCP server) and sccm is server2(SQL server and Primary Site Sever,DP,MP,SUP etc).



    Hope it helps. Thanks for your time.

    Best regards,
    Simon Ren

    Just adding one more question:  And to have a HA of SCCM with minimum amount of servers, we would need a remote SQL/SQL Cluster as well as two-2 SCCM Servers holding all the roles each?  Please, correct my understanding.

    Thanks in advance.

  • Thanks for the reply.

    During the course of asking questions here I came to know that not all servers roles in SCCM can be made into HA.

    Can you please share if that is indeed correct and what roles would that be?

  • Great Simon; appreciate it.

    So, i guess the recovery for these roles would just involve re-installation and re-configuration.  Please, enlighten.

    Thanks in advance.

    Just a quick question on the HA/DR of SCCM.  Can you share any link which I can read/follow for my strategy either technet or any other site?

    Thanks in advance.
