    Hi,

     

    I need to know how will the communication between 2 gateways servers in 2 diffrenet domains will take place or then cab directly connected to management servers.Which ports needs to be opened for their communication.

    and

    I need to know how will the communication between 2 MS servers\2 resource pools will take place and Which ports needs to be opened for their communication.

     Thank you Ahmed.

    I am sorry as I am looking for some different information.

    I have 2 gateway servers on two different domains. My question is do they require to communicate bet them .

    Similarly , I have 2 MS\Resource pool - One for servers  and another for Networking devices . Do they need to communicate bet each other.

    Hi Durgesh,

    Gateway server will always communicate to MS via certificate. They collect data in their respective domain and send to MS. You can have gw server running in a failover topology within that domain. Having gw communicating across domain is not supported....i have not seen that.

    Regarding your question on resource pool I'm not sure what exactly you mean by comm between each other as  -- resource pool are used for creating highly available env.

    Thank you Varun for replying.

    What i mean is I am keeping 2 MS in my design and One will monitor 100 n\w devices and other will monitor 600-700 servers.

    Hi,

    Both Gateway servers can communicate to 1 MS, nor each GW can communicate with seperate MS..

    Multiple Resource Pools > distribute the load (one for Network Devices and one for the Servers), multiple MS per REsource Pool to provide high availability..


    Hope this explain it..

    Hi.

    Gateways dont talk to eachother.

    Management servers in the same mgmt group can talk to eachother. Mainly on 5723, but you might open a scom console or do other shell like stuff which also requires 5724.

    For your design. If you have two central MS, I would recommend creating resource pool(s) that cover both the management servers, and have the resource pool be the target for your agents and network devices, so they load balance their stuff. Make sure in that case they have similar specs (cpu, ram, the standard stuff).

    Bob,

    Thank you for clearing my doubts on this. Just need to know that Can i have 2 MS in one resource pool and 1 ms will be deidcated to server monitoring and other one dedicated to Network monitoring and both of them be in one resource pool. If yes than I think I can load balance it.

    Please comment on this and then i will proceed installing the product.

    You can make combinations.
    So you have the all management servers pool where normally all MS live.
    You can make a network monitoring resource pool and add only one of the MS into it. ANd link your network device monitoring to that pool. that will force that MS to do network monitoring but can not fail over to the other MS as it is not in the resource pool. Still would suggest you keep it simple and add both those MS you have to that pool as well. they will load balance the load at about 50/50 load.

    Hi

    Just be aware that there are numerous references to "resource pools for servers" in this thread. I might be misunderstanding the reference but please be aware that Resource Pools do not apply to windows agents.

    Windows agents have a Primary Management Server and default behaviour (which can be changed using powershell) is to automatically failover to another management server if the primary isn't available.

    Linux \ Unix agents and Network devices can leverage a Resource Pool, as can notifications as these are activities that are carried out by the Health Service on the Management Server.

    Console connections, connectors and anything else that uses the SDK cannot use resource pools. You need to setup load balancing to have high availability here.

    So this means we cannot group 2 MS in one resource pool wherein 1 MS is for server monitoring -window based and few linux servers(max 50 ) and other for Network monitoring?

    Hi

    Correct - windows agents do not use resource pools. When you install the windows agent, you assign a primary management server and that is the one the agent will try to use. If it cannot contact that management server (fails 3 consecutive times) then it will automatically failover to any other management server.

    Cheers

    Exactly. You can of course install windows agents with the first one as primary and big chance it will carry most of the load for a while. And you can make a network monitoring resource pool and only place the other MS in it and deploy network monitoring from that resource pool and that would force the network monitoring to that box. However you have lost the easy failover and load balancing that way by forcing things to one server.

    There is a sizing guide that will help but ultimately high availability \ budgets \ number of management servers tend to be a balancing act. Virtualisation of the management servers can help lessen the cost:

    http://blogs.technet.com/b/momteam/archive/2012/04/02/operations-manager-2012-sizing-helper-tool.aspx

    And more importantly, what are your availability requirements? A SCOM 2012 Management Server running on Windows 2008 R2, SP1 reboots quickly. Can you lose monitoring for that period of time?

    This thread concentrates on Management Servers but do you have SQL clustered? If not, then you have your main single source of failure (and slowest rebooting component) there. Building a new management server and assigning it to a resource pool is trivial in comparison to recovering SQL.

    Cheers
