What is OMI?

Open Management Infrastructure (OMI) is an open source project to further the development of a production quality implementation of the DMTF CIM/WBEM standards. The OMI CIMOM is also designed to be portable and highly modular. In order to attain its small footprint, it is coded in C, which also makes it a much more viable CIM Object Manager for embedded systems and other infrastructure components that have memory constraints for their management processor. OMI is also designed to be inherently portable. It builds and runs today on most UNIX® systems and Linux. In addition to OMI’s small footprint, it also demonstrates very high performance.
