1. A midplane assembly, comprising:
a midplane having dielectric material and a set of plated through holes supported by the dielectric material, the dielectric material substantially defining a first side and a second side of the midplane, the set of plated through holes being arranged within the dielectric to form a first profile of plated through holes and a second profile of plated through holes, the first profile of plated through holes having (i) an overlapping portion which overlaps at least part of the second profile of plated through holes and (ii) a non-overlapping portion which does not overlap any part of the second profile of plated through holes;
a first connector arranged to mount to the first side of the midplane over the first profile of plated through holes; and
a second connector arranged to mount to the second side of the midplane over the second profile formed by the set of plated through holes;
at least one plated through hole of the set of plated through holes being a shared plated through hole which resides in both the first and second profiles and which engages a pin of the first connector and a pin of the second connector; and
at least one plated through hole of the set of plated through holes being a non-shared plated through hole which resides in the non-overlapping portion of the first profile and which engages a pin of the first connector without engaging any pins of the second connector.
