Sterile neutrinos produced through a resonant Shi-Fuller mechanism arearguably the simplest model for a dark matter interpretation origin of therecent unidentified X-ray line seen toward a number of objects harboring darkmatter. Here, I calculate the exact parameters required in this mechanism toproduce the signal. The suppression of small scale structure predicted by thesemodels is consistent with Local Group and high-$z$ galaxy count constraints.Very significantly, the parameters necessary in these models to produce thefull dark matter density fulfill previously determined requirements tosuccessfully match the Milky Way Galaxy's total satellite abundance, thesatellites' radial distribution and their mass density profile, or "too big tofail problem." I also discuss how further precision determinations of thedetailed properties of the candidate sterile neutrino dark matter can probe thenature of the quark-hadron transition, which takes place during the dark matterproduction.
