Synthetic I/O testing
To get a good indication about how well this particular reference configuration would scale for throughput, a set of
low level I/O testing was conducted. Table 12 shows some low level test data that was collected when testing the
I/O subsystem. An HP storage I/O tool for Linux was used to perform the synthetic I/O testing. Results were close to
the theoretical 19GB/sec bandwidth of this configuration.
