  • Page 93 SC846 Chassis Manual D-11 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 HBA. Other servers require a power control card with no motherboard and no HBA.
