Planning Operations Manager Server configuration

A single Operations Manager server with SQL Server and Management Server can host up to 10,000 data sources from up to 50 DPM servers. The recommended hardware for this computer is 12 GB with good efficient storage configured in RAID.

A multi-server Operations Manager setup with two computers, with SQL Server and Management Server on different servers can host up to 50,000 data sources from up to 100 dpm2012long severs. The recommended hardware is 12 GB on the Operations Manager server and 8 GB on the SQL Server with good efficient storage configured in RAID.

Typically, the memory usage on the Operations Manager server is:

• Operations Manager Console - approximately 300 MB
  
  
• Scoped Administrator Console – 50 to 120 MB
  
  
• Windows Presentation Foundation (WPF) - 30 to 50 MB
  
  
• On a typical computer with 2 GB memory, you can use 1 GB for monitoring, which allows you to have five scoped Administrator Consoles, an Operations Manager Console, and up to seven WPF dialogs.
  
  

If you are working with over 2,000 data sources on the DPM server, you need to make the following registry changes on the DPM server on which the Operations Manager agent is installed:

• Set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HealthService\Parameters\Persistence Version Store Maximum to 80 MB (5120). Default = 60 MB
  
  
• Set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HealthService\Parameters\Management Groups\<MG Name>\maximumQueueSizeKb to 100 MB. Default = 15 MB
  
  
• Set HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Modules\Global\PowerShell\ScriptLimit\QueueMinutes to 120 mins
  
  

For every 100000 entries (backups), you will need about 6.5 GB.

The things to consider when you are deciding on how much disk space you will needs are:

• Number of backups in the environment per day = Average number of backups per data source per day * Average number of data sources per DPM * Number of DPM servers.
  
  
• Retention period (in days)
  
  

The DPM scoped Administrator Console will not work over WAN that have a latency over 15 ms. Although the functionality will be available, the console will be unresponsive.
