Dell md1000 bonnie++ benchmarks

Following are the results of our testing of the Dell MD1000 with two raid controllers (Perc 5/e). Server was dell 2950, 8gb ram. Pay close attention to the seeks figure, as this important figure for databases (the sequential rates are not all that important). We tried various combinations of software raid and hardware raid in both active/active and active passive configurations.
