Summary Summary The Dell EMC OpenManage Integration with Microsoft Windows System Center (OMIMSSC) appliance for System Center Operations Manager (SCOM) provides an option to configure Alert Relay Servers (previously known as Proxy Management Servers). When you want to scale up your infrastructure by including more devices, you can seamlessly scale up your monitoring capabilities by adding Alert Relay Servers in to your OMIMSSC environment.
Overview of Dell EMC Alert Relay Servers (previously known as Proxy Management Servers) 1 Overview of Dell EMC Alert Relay Servers (previously known as Proxy Management Servers) Dell EMC Alert Relay Servers are virtual machines running on Windows Server Operating System which is introduced from Dell EMC OpenManage Integration for Microsoft System Center—Operations Manager version 7.
Overview of Dell EMC Alert Relay Servers (previously known as Proxy Management Servers) 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.

Monitoring Dell EMC devices 3.2 Synchronize Alert Relay Servers with OMIMSSC appliance for SCOM 1. In the left pane of the SCOM console, select Monitoring and expand Dell EMC OpenManage Integration Views Dell EMC OpenManage Integration Dashboard. 2. Log in to OMIMSSC by using the local administrative privileges of the Management Server. 3. On the home page, scroll down to the Synchronized SCOM Management Servers and Dell EMC Alert Relay Servers section and click Sync with SCOM MS. 4.
Deployment scenarios 4 4.1 Deployment scenarios The Dell EMC devices can be discovered and monitored on the SCOM console using the Dell EMC OMIMSSC appliance. One instance of OMIMSSC provides support to one Management Group for the discovery and monitoring of devices. You can configure SCOM Management Servers and Dell EMC Alert Relay Servers as per the deployment scenarios required for your environment.
Deployment scenarios Dell EMC devices discovered from OMIMSSC Appliance (SCOM 2012 R2 to latest SCOM) Maximum count of Dell EMC Devices per Alert Monitoring Relay Server mode specific to the Monitoring mode Scalable 250 Number of Alert Relay Servers to be configured Number of Management Servers to be configured =(Total number Maximum of the two numbers: of Dell EMC devices) / 250 • Number of Alert Relay Servers / 4.
Deployment scenarios Dell EMC devices discovered from SCOM console; iDRAC – SMASH Monitoring Template, Chassis, and Network Switches as Network Devices (SCOM 2012 R2 to latest SCOM) Monitoring mode Maximum count of Dell EMC Devices Number of Alert per Alert Relay Number of Management Servers to Relay Servers to Remarks Server be configured be configured specific to the Monitoring mode Scalable 250 =(Total number of Dell EMC devices) / 250 Total of the two numbers: • • Number of Alert Relay Servers /
Deployment scenarios 4.2 Examples of deployment scenarios The Microsoft SCOM sizing guide provides details on the required number of SCOM Management Servers for the number of devices discovered using the OMIMSSC appliance (with the number of network devices set to zero) and using the SCOM console. • • Dell EMC Devices discovered from OMIMSSC appliance: As per the Sizing helper guide: o In Scalable monitoring mode: Every 3000 Dell EMC devices require one MS.
