D-13 Supported Cascading Configurations
Cascading allows the system to access data at a faster rate by allowing several
backplanes to share resources to reduce latency time.
The first backplane in a cascaded system requires a motherboard and an HBA.
Other servers require a power control card with no motherboard and no HBA. For
more information, see the SC846 Chassis Manual available at www.supermicro.
