The Cubby design is a new shelf and power distribution design that is fully compatible with Open
Rack V1 and forward compatible with Open Rack V2. The objective of the design is to further
reduce the cost of the individual nodes and rack infrastructure while at the same time increasing
the flexibility of the rack interface to support future designs. This new shelf design, hereafter
referred to by its project name Cubby, provides three bays and occupies 2 Open U (96mm).
