Abstract

Claims (45)

1. A computer-implemented method for dividing a physical Ethernet port, comprising:

dividing, by a computing device, a first physical Ethernet port of a plurality of physical Ethernet ports into a plurality of partitions using NIC partitioning;

assigning a first partition of the plurality of partitions for the first Ethernet port to a N-virtual distributed switch;

assigning a second partition of the plurality of partitions for the first Ethernet port with a plurality of functions using single root IO virtualization;

switching of Ethernet packets between a physical function and a virtual function of the plurality of functions in the second partition;

wherein dividing the physical Ethernet port includes simultaneously using NIC partitioning and single root IO virtualization on the physical Ethernet port;
