I don't see an ODA space in the OTN community - though one does exist in the MOS Community. Having one would be helpful. I think it would best be located under "Server and Storage Systems" > "Engineered Systems". In fact, I think this is the same location where Exadata, Exalogic, Exalytics and other Engineered Systems related spaces should be located as well - more similar to how they are categorized in the MOS community. Currently the only sub space in Engineered Systems inis the ZFS Storage Appliance - which is much more loosely defined as an engineered system than these others. Having the other engineered systems seem spread across all different locations - many of which don't seem to fit very well - seems confusing.
