5 Scalability with Dell EMC OpenManage Integration with Microsoft System Center (OMIMSSC) for System Center
Operations Manager (SCOM)
1 Monitoring more devices with OMIMSSC by using Proxy
Management Servers (henceforth referred to as Dell EMC
Alert Relay Servers)
1.1 Overview of Proxy MS
Proxy MS (henceforth referred to as Dell EMC Alert Relay Servers) is a virtual machine running on Windows
Server Operating System that is introduced for Dell EMC OpenManage Integration for Microsoft System
Center—Operations Manager (version 7.1 and later) to offload the monitoring, performance metrics, and
SNMP Alerts work flows from the Management Server and thus helping in scaling the number of devices
being monitored within a Management Group. The Management Server and Proxy MS are in the same
domain. Discover the Proxy MS as an Agent-Managed Windows computer in the Operations Manager
console.
1.2 Benefits of Proxy MS
In Dell EMC Server Management Pack version 7.0, when a management group consisting of five
management servers is used, a maximum of 600 devices can be monitored in the scalable mode. In
OMIMSSC 7.1 and later versions, with the introduction of proxy management server (henceforth referred to
as Dell EMC Alert Relay Servers), you can achieve higher scalability of monitored devices—nodes in
multiples of thousands.
NOTE:
• The proxy management server feature is supported only on Microsoft SCOM 2016 and later
versions.
• For enhanced scalability of nodes, setting up Proxy MS is mandatory for proper functioning of
OMIMSSC appliance.
1.3 Proxy MS system requirements
The following are the minimum software and hardware requirements of a Windows VM to host the Proxy MS
(henceforth referred to as Dell EMC Alert Relay Servers).
• Supported operating system on the MS for:
