1.1VirtualNICInterface
Solarflare’sVNICarchitectureprovidesthekeytoefficientserverI/Oandisflexible
enoughtobeappliedtomultipleserverdeploymentscenarios.Thesedeployment
scenariosinclude:
•KernelDriver–ThisdeploymentusesaninstanceofaVNICperCPUcorefor
standardoperatingsystemdrivers.Thisallowsnetworkprocessingtocontinue
overmultipleCPUcoresinparallel.Thevirtualinterfaceprovidesa
performance‐optimizedpathforthekernelTCP/IPstackandcontention‐free
accessfromthedriver,resultinginextremelylowlatencyandreducedCPU
utilization.
•AcceleratedVirtualI/O–Theseconddeploymentscenariogreatlyimproves
I/Oforvirtualizedplatforms.TheVNICarchitecturecanprovideaVNICper
