33 Dell Compellent Storage Center Management Pack 3.0 for Microsoft SCOM 2012/R2 Best Practices
6.4 Enterprise Manager memory settings
Enterprise Manager can be used to monitor multiple Storage Centers throughout the enterprise. As the
amount of Storage Centers and data collected increases, Enterprise Manager can suffer performance
degradation. This can negatively affect SCOM, as well as other applications that rely on Enterprise
Manager as a data collector.
To allow scaling in the amount of Storage Centers monitored, the amount of system memory Enterprise
Manager uses can be configured during installation. Memory settings are based on the total number of
Storage Centers and/or total volumes to monitor. As shown in the graphic below, Enterprise Manager can
be configured to monitor multiple Storage Centers and over 5000 total volumes.

Note: When making changes to memory settings, it is important to consider how much memory is being
consumed by the server and other running processes. Make sure that there is enough available memory
on the server to match the Enterprise Manager settings. Setting the max memory too low can have
adverse effects on Enterprise Manager and applications that use it. Setting the max memory too high can
have an adverse effect on the server and all its running applications, as well as potentially cause
Enterprise Manager not to start.
6.4.1 Modifying memory settings on an existing Enterprise Manager installation
To modify the maximum amount of memory, Enterprise Manager can use in an existing installation:
1. Open Dell Compellent Enterprise Manager Data Collector Manager.
2. Log on as a user with administrator rights.
