How is the Node ID created?

In various place I see referece to the node id (or nodeid). How is this generated?

What impact does it have?

Understanding Node id to mac address translation:

Assume your Mac Address is : # HWaddr 20:CF:30:ED:D8:E4

And fabric port is configured to use port 3001

In that case Node id will be : BB9E4D8ED30CF20


First 3 characters BB9 (0 is removed by print) - this relates to port 3001 in aerospike.conf

E4D8ED30CF20 - Rest is the mac address in reverse order of mac address (20:CF:30:ED:D8:E4)
