1. 4 Nodes, No Replicate, Adjust Parameters

$ iozone -g 16g -aRb test.wks

3. Performance

The following six diagrams show the testing results using IOzone as the benchmark to evaluate how Lustre works with and without data-replication. The six IO operations we have done for performance evaluation are write, re-write, read, re-read, random read, and random write opertion, respectively.
