11 Scalability with Dell EMC OpenManage Integration with Microsoft System Center (OMIMSSC) for System Center
Operations Manager (SCOM)
Scenario 2: Devices discovery using Dell EMC OMIMSSC (iDRAC, chassis, network switch)
Dell EMC devices are discovered as iDRAC, Dell EMC Chassis, or Dell EMC Network. The inputs are
provided in the OpenManage Integration Dashboard and during discovery, the IP address range is provided,
and appropriate credential profile is associated with the job.
Scenario 2. Use-case scenarios for configuring proxy management server on management server
running on SCOM 2016 and later versions

• NOTE: To achieve higher scalability numbers, you can do a horizontal scaling of
management group as per the Microsoft Sizing guide. In that case, every Management group
requires a new OMIMSSC appliance.
1.8 Add proxy management servers to the proxy management server
group (ProxyMSGroup)
After enrollment, a group named DellProxyMSGroup is created. Proxy management servers that are
discovered in SCOM console as an Agent-Managed Windows computer are required to be added to the
group DellProxyMSGroup, and then perform synchronization with SCOM from the OpenManage Integration
Dashboard.
• NOTE: Before adding proxy management servers to the proxy management server group,
install the Operations Manager Agents on all proxy management servers by performing
following steps.
