  • Hi,

    1.  What are the minimum number of servers required to implement an SCOM Solution (All Roles)?

    Answer: You can implement everything on one (1) single standalone server.

    2.  What server roles can be collocated on the same server?

    Answer: See answer above.

    Normally you would at least have the database on a separate server, the rest can be on one (1) standalone server, depending on your organization's size and limitations.



    Best regards,
    Leon

  • Thanks for the reply.

    So, basically only one-1 Server can accommodate all the roles including Management Server, Database, Runbook Server, Web Service, Runbook Designer and Tester?  Please, correct my understanding.

    Just adding one more question:  And to have a HA of SCO with minimum amount of servers, we would need a remote SQL/SQL Cluster as well as two-2 SCO Servers holding all the roles each including Runbook Server, Web Service, Runbook Designer and Tester.  And only one server will hold Management Server as it cannot be shared by design?  Please, correct my understanding.

    Thanks in advance.

    Answer: Yes.

    For high availability (HA), you would need at least one (1) more runbook server, and for the database you would have a SQL cluster.

    For the SCOM web console you can put it behind a NLB (Network Load Balancer).

    There can only be one (1) Orchestrator management server yes.

  • So, just to summarize

    Two-2 Servers Holding DB (Cluste/AO)

    Two-2 Servers Holding Management Server, Runbook Server, Web Service, Runbook Designer and Tester

    Total of Four-4 Servers.  Please, confirm my understanding.

  • Preferably a simple SQL Server stretch cluster, but yes a minimum of  two (2) cluster nodes.

    One Management Server, and one Runbook server, remember that the management server can function as a runbook server as well, this way you will have two runbook servers in total.

    So a total of four (4) servers yes:

    Two (2) SQL Server cluster nodes in a cluster.

    • SQL Server cluster node 1
    • SQL Server cluster node 2

    One (1) management server

    • Management Server role
    • Runbook Server role
    • Runbook Designer
    • Web Service

    One (1) runbook server:

    • Runbook Server role
    • Runbook Designer

  • Hi,

    just one add to Leons post above. I would install Web Services also on the one with "Runbook Server" Role. So you can control (Start/Stop) Runbooks even the system with Management Server role is down. If you install Web Services on two systems you can put them into a NLB.

    Management Server should only be installed on one system. You need Management Server to connect wit Runbook Designer.
