Our findings reveal interesting data relating to the number of read and write events. We notice that the number of read and write events is significantly less than creates and the average number of bytes exchanged per I/O is much smaller than what has been seen in previous studies.
%the average of bytes transferred over the wire is much smaller than what has been seen in previous studies.
Furthermore we find an increase in the use of metadata for overall network communication that can be taken advantage of through the use of smart storage devices.
