Executive Summary: The traditional approach to server systems management has been to install an agent in the server’s operating system, and proceed from there. Years ago, Operating System (OS)-resident (also known as in-band) agents were needed to connect to various platform components in order to be able to discover, configure, update, and monitor the device. However, with Dell’s introduction of the seventh version of the integrated Dell Remote Access Controller (iDRAC) with the twelfth generation of PowerEdge servers, that need was drastically reduced as iDRAC’s “bare metal” or out-of-band management capabilities had become quite extensive. As Dell has added additional improvements to iDRAC8 and the thirteenth generation of servers, the gap between in-band and out-of-band management capabilities has continued to narrow. There are, however, still some functions that require the use of the in-band agent, OpenManage Server Administrator (OMSA); this paper includes a detailed functionality chart, making it easy to identify supported functions for each type of management.

Great idea - any chance the comparison could include the BMC / IPMI feature sets alongside the iDRAC & OMSA ones? Thanks!
