Advantages of using dual port HBA

The key feature separating the dual port from the traditional single port cards or competing dual port cards is the complete separation of channels on one HBA. Because each port on the HBA has its own logic and Fibre Channel dedicated ASIC chipset, each port operates independently from the other. Adapter performance is never compromised and each port is separately configured. For example, one port of the HBA can be running in a loop environment, while the other port operates in a switched fabric or point-to-point configuration.
