5–Validation Methods for DCB and FCoEValidation Step 7—Virtualization Verification5-30 51031-00 A6. Configure the test as follows: Trigger: any PFC frame Post fill: 90 percent after the trigger Data size: 512K Traffic: 100 percent read on both virtual machines7. Use Analyzer to capture a trace.8. Use Expert to analyze the trace, and calculate the average, minimum, andmaximum throughput results per priority.9. Compare I/O performance for the two virtual machines.Repeat the entire test, using separate hosts for the iSCSI initiator and the FCoEinitiator, and compare I/O performance.Validation ResultsOne virtual machine ran the FCoE read application, and the other virtual machineran the iSCSI read application. Figure 5-31 shows the throughput results forindividual and combined applications.Figure 5-31. FCoE and iSCSI Application Throughput in a Virtual EnvironmentiSCSI throughput increases whenFCoE traffic decreases in the absenceof PFC pauses
