Validation Results; Fcoe And Iscsi Application Throughput In A Virtual Environment - Qlogic Storage Networking (Unified Fabric Pilot Installation Manual

5–Validation Methods for DCB and FCoE
Validation Step 7—Virtualization Verification
6. Configure the test as follows:




7. Use Analyzer to capture a trace.
8. Use Expert to analyze the trace, and calculate the average, minimum, and
maximum 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 FCoE
initiator, and compare I/O performance.

Validation Results

One virtual machine ran the FCoE read application, and the other virtual machine
ran the iSCSI read application.
individual and combined applications.
iSCSI throughput increases when
FCoE traffic decreases in the absence
of PFC pauses

Trigger: any PFC frame
Post fill: 90 percent after the trigger
Data size: 512K
Traffic: 100 percent read on both virtual machines
