NPIV

� N_Port ID Virtualization or NPIV allows multiple Fibre Channel initiators to occupy a single physical port.

� NPIV virtual adapter definitions & PowerHA work just like an environment using dedicated adapters

� The NPIV functionality presents an attractive offering for customers trying to circumvent under utilized resources. In one way standby configurations the


circumvent under utilized resources. In one way standby configurations the fallover server would not need a dedicated HBA

� NPIV allows you to run an environment with dedicated HBAs on the prod side and virtual on the target machine, or both virtual emulating a direct attached environment
