Chapter 3: Dual Port and Cascading Configurations
3-5 Supported Cascading Configuration
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 HBA hosted with a mother
-
board. Other servers require only a power control card without an HBA and without
a motherboard.
Other Considerations:
•
Cascading supports up to one hundred twenty-two hard drives.
•
Use the same cables for all single port configurations.
•
See page 3-7 if your HBA is external to your backplane.
