- In-Band: This requires the installation of OMSA and the SCOM agent on the systems that you want to monitor. Processing of data is done on the monitored system by the SCOM agent. This is also much easier to setup.
- Out-of-Band: This does not require OMSA or the SCOM agent, but does require setting up SMASH discovery through the iDrac, a license from Dell, and the Dell Connections License Manager. Processing of data is done on the SCOM Management Server. I have another post on how to set this up in a single SCOM management server environment.
- Scalable: Inventory and monitoring of component groups and also displays the presence of the iDrac. For Reports, only OpenManage Windows Event log is available.
- Detailed: Detailed inventory and monitoring of the following components: memory, processors, network interfaces, storage controllers, disks, volume, power, temperature, and BIOS information. For Reports, availability of BIOS configuration, firmware and driver versions, and RAID configuration reports.
