20. SR-IOV & PassThrough
Physical NIC Dedicated Divided From Physical NIC to Virtual Functions
Network Bandwidth Enhanced
(SR-IOV Supported NIC Only)

21. Vyatta vRouter5600 Performance
Using 2 vCPU
Direct Connect from Server to IXIA
(Using SR-IOV, 1 VM Running)

22. Beyond Performance, Go for Efficiency
1 U Server -> 40 VM
