SAS-216EL Backplane User's Guide 3-4 Supported Cascading Confi gurations Cascading allows the system to access data at a faster rate by allowing several backplanes to share resources to reduce latency time. The fi rst backplane in a cascaded system requires a motherboard and HBA. Other servers require a power control card with no motherboard and no HBA. For more information, see the SC216 Chassis Manual available at www.supermicro.com.
