Sizing for Standalone Installations
The following are suggested sizing guidelines for your Dell OpenManage Network Manager system.
1
Assumptions: Servers have at least four cores and are no more than four years old. As memory and
usage increases, the number of CPU cores increase. Two cores can work for the most basic installations,
but are not recommended.
2 Each device is equivalent to a L2 or L3 switch with a total of 48 interfaces per device being monitored.
For each of devices not being monitored for 48 interfaces, one can add another 50 devices to the overall
inventory for ICMP-only monitoring.
3
Application Constraints are most relevent to Traffic Flow Analysis, Peformance Management, and Event
Management.
Traffic Flow Analysis ratings map to constant throughput divided by sample rate, as in bandwidth /
sample rate. 20G / 2000 is easier to manage than 20G / 1000. 20G / 1 is a thousand times more demanding
than 20G / 1000. Best practice is to avoid such high sample rates. The bandwidth the hardware your Dell
OpenManage Network Manager installation can support is dramatically lower in such cases. Best
