Overview of Dell EMC Alert Relay Servers (previously known as Proxy Management Servers)
6 Scalability with Dell EMC OpenManage Integration with Microsoft System Center (OMIMSSC) for System Center
Operations Manager (SCOM)
with the introduction of Alert Relay Servers, you can achieve higher scalability of monitored devices—nodes
in multiples of thousands.
NOTE: The Alert Relay Server feature is supported only on Microsoft SCOM 2012 R2 and later versions.
1.2 Best practices in configuring Alert Relay Servers
• You must configure Dell EMC Alert Relay Servers in your SCOM Management Group to monitor Dell
EMC devices using the OMIMSSC appliance.
• Based on the number of devices that you want to monitor on the SCOM console, you configure Alert
Relay Servers accordingly. Each Alert Relay Server can monitor a maximum of 250 devices in the
Scalable mode or 30 devices in the Detailed mode.
• In the Scalable mode, maximum number of Alert Relay Servers that can be hosted on a single
Management Server is four and each Alert Relay Server can monitor 250 devices.
• In the Detailed mode, maximum number of Alert Relay Servers that can be hosted on a single
Management Server is two and each Alert Relay Server can monitor 30 devices.
• Symmetrically distribute the Alert Relay Servers across all the Management Servers in the resource
pool.
• Ensure not to overload Management Servers by adding a greater number of Alert Relay Servers.
NOTE: In the Scalable mode of OMIMSSC, inventory and health monitoring details are displayed up to the
device and component group level. However, in the Detailed mode of OMIMSSC, inventory, and health
monitoring details are displayed for individual components such as memory, processors, Compute Usage
Per Second (CUPS), BIOS, and sensors in addition to the group level details.
1.3 Alert Relay Servers system requirements
The following are the minimum software and hardware requirements of a Windows VM on the managed node
to host Alert Relay Servers.
