* What is NPIV and why does it matter?
NPIV stands for N_Port ID Virtualization. It means you can make a single physical port look like multiple (virtual) ports to a Fibre Channel switch. It can reduce the number of physical connections required when plugging into the switch.

Without NPIV, each tape library/drive must use a physical connection to the switch. FC switches can be pretty expensive, so being able to use fewer physical connections is a good thing. With NPIV you can now present up to 15 tape libraries/drives per physical connection.
