Network Storage

Ali,
	Do you need to capture the whole packet, including the payload? You
will save a lot of space by just capturing the headers. For example,
tcpdump doesn't capture the whole packet by default anyway. You may not
be able to capture at line rate anyway depending on what you are using
to capture with (drivers, libraries, software, etc). See the -s option
in tcpdump man page for info.

Good luck,
Mike
