It is a compact, high-density, high-performance, rack-mounted, scalable server platform system. The NeXtScale n1200 Enclosure Type 5456 chassis has twelve node bays. A 1-bay compute node occupies one node bay in the chassis. A 2-bay storage tray or GPU tray occupies two node bays in the chassis. The nodes share common resources, such as power and cooling in the chassis.
