A midplane is defined as a plane that is orthogonal to an edge joining any two vertices that also contains the centroid of an opposite edge formed by joining the other two vertices.
A "virtual midplane" is an imaginary plane between vertical cards on one side that directly connect to horizontal boards on the other side; the card-slot aligners of the card cage and self-aligning connectors on the cards hold the cards in position.
One common orthogonal midplane connects many vertical telephone line cards on one side, each one connected to copper telephone wires, to a horizontal communications card on the other side.
Some people use the term "midplane" to describe a board that sits between and connects a hard drive hot-swap backplane and redundant power supplies.
This ability to plug cards into either side of a midplane is often useful in larger systems made up primarily of modules attached to the midplane.
