Hi
I am on MCEP 2002 version, I have Two SCCM servers

SAN – Content Library
Server1 – SQL DB and Site Server Role (Active) (With SMS Provider)
Server 2 – MP, DP and SUP Role

Now I have to configure high Availability using two additional servers

Server 3 – Passive site server Node with SQL DB using Windows Cluster and SQL Always ON
Server 4 - MP,DP,SUP roles for Passive Node. (and SMS Provider)

Will this work or recommend the configuration design?

Challenges:
If I have SQL DB and Site System server install on same server , will that allow me to configure cluster and SQL Always ON (Between Server 1 and Server 3)

My Server 4 will be a load balancer for active setup or they will be active only after passive Server is up? How they will be linked to passive node for HA?

    Thank you for posting in Microsoft Q&A forum.

    1. Yes, we could build the structure. Please remember the following prerequisites are included in it:
      The site database server must be remote from the site server;
      The computer account of the site server has Administrators permission in this cluster.
      SSL/TLS and PKI certificates requirements when you use a failover cluster instance for the site database.
      Please refer the following SQL configure article for more details:
      use-a-sql-server-cluster-for-the-site-database
    2. Install an additional site server in passive mode for a standalone primary site. The site server in passive mode is in addition to your existing site server in active mode. A site server in passive mode is available for immediate use, when needed. To make the site server in passive mode become active, you manually promote it. This action switches the site server in active mode to be the site server in passive mode. The site system roles that are available on the original active mode server remain available so long as that computer is accessible. Only the site server role is switched between active and passive modes.
      For more details, please refer to this article:
