9 Scalability and performance of Dell EMC OpenManage Essentials version 2.5
Recommendations for using discovery and inventory features of
OME
• Usage of recommended hardware and software components according to the number of devices
managed.
• The ICMP and SNMP retry and timeout values must be increased if the network usage is high.
• Select only the protocols necessary for a particular discovery and inventory task because selecting all
the protocols causes the discovery and inventory task to run slower.
• For ICMP related settings in OME, see the OpenManage Essentials 2.5 User’s Guide.
Throttle (speed) value
After installing OME, the default value of throttle (speed) is set to 50%. This setting can be changed to any of
the speeds available.
A comparison of performance data by using different throttle values is also provided in Table 2 and Table 3.
These tables can be used to determine the correct throttle value for your system. For a higher throttle value,
OME performance improves at the cost of increased system resource.
Figure 1 displays the OME page on which you can change the throttle (speed) setting. The following paths
may be followed to access the throttle configuration page:
• Discovery — Start the OME Console and click Manage  Discovery and Inventory  Discovery
Schedule. Configure the throttle by using the Discovery Speed slider.
• Inventory — Start the OME Console and click Manage  Discovery and Inventory  Inventory
Schedule. Configure the throttle by using the Inventory Polling Speed slider.
• Health Monitoring — Start the OME Console and click Manage  Discovery and Inventory 
Status. Configure the throttle by using the Status Polling Speed slider.
• Configuration Inventory — Start the OME Console and click Manage  Configuration 
Configuration Inventory Schedule. Configure the throttle by using the Inventory Polling Speed
slider in the Schedule section.
