Plan for DPM deployment with Operations Manager
Updated: November 1, 2013
Applies To: System Center 2012 - Data Protection Manager, System Center 2012 R2 Data Protection Manager, System Center 2012 SP1 - Data Protection Manager
As you consider the number of servers running System Center 2012 – Operations Manager that your organization requires, this section will give you broad guidelines to help you make better decisions.
Single or multiple Operations Manager servers
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.
Memory usage on Operations Manager server
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.
Working with more than 2,000 data sources
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
Planning the Operations Manager data warehouse database size
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)
Working over Wide Area Networks
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.
