For the sequential tests, file size was varied along with the number of clients such that the total
amount of data written was 256G (number of clients * file size per client = 256G).
IOzone Sequential Writes
# /usr/sbin/iozone -i 0 -c –e –w –r 1024k –s 4g –t 64 -+n -+m ./clientlist
IOzone Sequential Reads
# /usr/sbin/iozone -i 1 -c -e -w -r 1024k -s 4g -t 64 -+n -+m ./clientlist
For the random tests, each client read or wrote a 4G file. The record size used for the random tests
was 4k to simulate small random data accesses.
