I have a basic question. This was asked to me on an interview for which i was not able to answer.
Q: WWN is a 64 bit unique identifier and is given for each port and node and also for switches.Why do we need an seperate FCID in fibre channel when we have a unquie WWN. Why cannot we use the WWN for sending frames.
Thanks In Advance for your answer...
