Some Best Practices for OpsMgr 2012

Disk Configuration

For all server roles (management server, databases, gateway server), we recommend storage controller with battery-backed write cache enabled  (256 MB minimum recommended).


For large scale environment (>1000 Agents), we require a  SQL Temp DB with 8GB data and 2GB log.

For large scale environment (>1000 Agents), we highly recommend a high performance SQL Temp DB.

High Availability

The recommended configurations include one additional server as a failover server for each scenario.

Additional servers are recommended for high availability when more than one server goes offline.

The failover server should use the hardware specification of the management server that manages the highest number of agents.

Network Monitoring

Create resource pool dedicated to network monitoring.

Add dedicated management servers to newly created resource pool.

Remove dedicated management server from any other resource pool.  Ex. The "All Management Servers Pool"


All Operations Manager 2012 server roles can be virtualized with Hyper-V as long as the virtual machines are configured with the recommended hardware.
