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, but not a motherboard and HBA together.
C-13 Supported Cascading Configurations
Other Considerations:
•
Cascading supports up to one hundred twenty-two hard drives
•
Use the same cables for all single port configurations
