Abstract

A method, computer program product, and computer system for dividing a physical Ethernet port is provided. The method may include dividing, by a computing device, a first physical Ethernet port of a plurality of physical Ethernet ports into a plurality of partitions. A first partition of the plurality of partitions for the first Ethernet port may be assigned to a N-virtual distributed switch. A second partition of the plurality of partitions for the first Ethernet port may be assigned with a plurality of functions. Ethernet packets may be switched between the plurality of functions in the second partition.

First claim

What is claimed is:

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;
creating a symmetric configuration of the first physical Ethernet port on a second physical Ethernet port of the plurality of Ethernet ports; and
forming teaming policies by aggregating the first physical Ethernet port and the second physical Ethernet port, the teaming policy including:
assigning the first partition of the first physical Ethernet port and a first partition of the second physical Ethernet port as uplinks to the N-virtual distributed switch;
using the physical function of the second partition of the first physical Ethernet port and a physical function of a second partition of the second physical Ethernet port for management, vMotion, and user traffic, and creating port binding for storage traffic to enable multi-pathing; and
assigning the virtual function of the second partition of the first physical Ethernet port and a virtual function of the second partition of the second physical Ethernet port to a storage system controller virtual machine, wherein the virtual function of the second partition of the first physical Ethernet port and the virtual function of the second partition of the second physical Ethernet port are not teamed together.

2. The computer-implemented method of claim 1 wherein a first function of the plurality of functions on the second partition is the physical function and is assigned to a virtual distributed switch, and wherein a second function of the plurality of functions on the second partition is the virtual function and is assigned to a controller virtual machine.

3. The computer-implemented method of claim 2 wherein the physical function on the second partition and the virtual function on the second partition are single root IO virtualization functions created on a single root IO virtualization enabled adapter.

4. The computer-implemented method of claim 3 wherein a loopback capability is provided between the physical function and the virtual function of the second partition.

5. The computer-implemented method of claim 3 wherein bandwidth allocation for the second partition is subdivided between the physical function and the virtual function.

6. A computer program product residing on a non-transitory computer readable storage medium having a plurality of instructions stored thereon which, when executed across one or more processors, causes at least a portion of the one or more processors to perform operations comprising:
dividing 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;
creating a symmetric configuration of the first physical Ethernet port on a second physical Ethernet port of the plurality of Ethernet ports; and
forming teaming policies by aggregating the first physical Ethernet port and the second physical Ethernet port, the teaming policy including:
assigning the first partition of the first physical Ethernet port and a first partition of the second physical Ethernet port as uplinks to the N-virtual distributed switch;
using the physical function of the second partition of the first physical Ethernet port and a physical function of a second partition of the second physical Ethernet port for management, vMotion, and user traffic, and creating port binding for storage traffic to enable multi-pathing; and
assigning the virtual function of the second partition of the first physical Ethernet port and a virtual function of the second partition of the second physical Ethernet port to a storage system controller virtual machine, wherein the virtual function of the second partition of the first physical Ethernet port and the virtual function of the second partition of the second physical Ethernet port are not teamed together.

7. The computer program product of claim 6 wherein a first function of the plurality of functions on the second partition is the physical function and is assigned to a virtual distributed switch, and wherein a second function of the plurality of functions on the second partition is the virtual function and is assigned to a controller virtual machine.

8. The computer program product of claim 7 wherein the physical function on the second partition and the virtual function on the second partition are single root IO virtualization functions created on a single root IO virtualization enabled adapter.

9. The computer program product of claim 8 wherein a loopback capability is provided between the physical function and the virtual function of the second partition.

10. The computer program product of claim 8 wherein bandwidth allocation for the second partition is subdivided between the physical function and the virtual function.

11. A computing system including one or more processors and one or more memories configured to perform operations comprising:
dividing 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;
creating a symmetric configuration of the first physical Ethernet port on a second physical Ethernet port of the plurality of Ethernet ports; and
forming teaming policies by aggregating the first physical Ethernet port and the second physical Ethernet port, the teaming policy including:
assigning the first partition of the first physical Ethernet port and a first partition of the second physical Ethernet port as uplinks to the N-virtual distributed switch;
using the physical function of the second partition of the first physical Ethernet port and a physical function of a second partition of the second physical Ethernet port for management, vMotion, and user traffic, and creating port binding for storage traffic to enable multi-pathing; and
assigning the virtual function of the second partition of the first phys
