Number of Bytes Per Inode - how many I-nodes do you want in your file system.
If a file system is going to contain lots of small files, which would be
contained in fragments, you'd pick a smaller NBPI, and get more I-nodes.
Conversely, if a file system is going to contain fewer, larger files, you'd
pick a large value of NBPI, and get fewer I-nodes. NBPI is basically a tuning
parameter that allows you to try and maximize the space usage in the file
system.
