The current version of openwsman uses the sfcc (Small Foortprint CIM Client) to connect to any CIMOM running on the same host using cimxml. This is not optimal and comes with some overhead, however the intention of the project is to initially support all CIMOMs and there is no common protocol or client interface that can be used to talk to all available CIMOMs.

We have tested with two CIMOMs and all other CIMOMs with cimxml support should also work, the CIMOMs we have tested with are:

• SBLIM SFCB -- The Small Footprint CIM Broker can be accessed either via the default CIMXML interface or using a local binary interface which works without CIMXML.
• Openwbem -- OpenWBEM is an enterprise-grade open-source implementation of WBEM, written in C++, suitable for commercial and non-commercial applications. Openwbem is the default CIMOM in Novell products, especially SLES10. An experimental requesthandler for openwbem also exists. This handler uses the openwsman library to make openwbem accept WS-Management connection directly and without the openwsman service.
