Dell EMC OpenManage Enterprise Power Manager Version 2.0 User’s Guide
Scalability and performance
Power Manager supports up to 8,000 target devices that include 500 groups—static and physical groups, servers, virtual machines, and Power Distribution Units (PDUs).
Configure appropriate power and temperature sampling intervals in Power Manager. The sampling intervals impact the system performance and footprint significantly, including network bandwidth consumption, database size, and trend graph display latency.
The default power and temperature intervals in Power Manager are 15 minutes. This value is appropriate for small or medium-sized environments where the device number is less than 1,000. However, when the environment has more managed devices, the interval is automatically set to 30 minutes.
