What is Virtual Networking ?

Hello guys in this post i will give you brief summary about the Virtual Networking in the Virtual Infrastructure & we will also discuss components of virtual networking.

As you can see in the physical world we use Networking to connect the various devices & servers to switch & routers in order to make connectivity between them. VMware also provides the Virtual Networking same as the physical network to connect the Virtual machines to the Storage , Virtual Switch & to connect the outside network.

It is also an important task to design & build the virtual network in a way so that it can provide the better connectivity to the virtual server’s to physical network & storage. Design a virtual network in a way so it will be easy to maintain the virtual network.

VMware provides the many components in the virtual network let’s discuss below.
Components of Virtual Network:-

  1. vSphere Standard Switch:-
    vSphere Standard switch is the software-based virtual switch used to connect virtual machines to ESXi host & it also provides the connectivity between the virtual machines on that virtual switch. vSphere Standard Switch is referred as vSwitch. Each ESXi host requires it’s own vSwitch.
  2. vSphere Distributed Switch:-
    vSphere Distributed Switch is also software-based virtual switch used to connect your virtual infrastructure. vSphere Disrtibuted switch referred as VDS . VDS is shared & managed at the Datacenter across all the ESXi hosts & clusters. VDS provides the centralized management of the Network.
  3. VMkernel Port:-
    VMkernel Port is an specialized virtual switch port. It requires the IP Address to be configured on VMkernel port. VMkernel Port is also referred as Management Network. It allows the ESXi management traffic, vMotion traffic, iSCSI storage access, vSAN Traffic & many more. It support VLAN Tagging.
  4. VM Port Group:-
    VM Port Group is a group of ports on vSwitch to share & access common configuration between virtual machines. It also referred as VM Network (Virtual Machine Network). It also supports the VLAN Tagging.
  5. NIC Teaming:-
    Network Interface Card Teaming requires at least two NIC to setup NIC Team. It forms a single logical communication channel between multiple NIC. It provides various levels of traffic Load balancing & fault tolerance.
  6. VLAN:-
    VLAN is Virtual LAN used to create logical group of Network on virtual or physical switch. VLAN also called as Virtual LAN used on virtual or physical switch. It provides the traffic segmentation, security ,broadcast control etc.
  7. VMXNET Adapter:-
    VMXNET Adapter is special virtualized adapter used in the guest operating system to provides the high-performance network connectivity. It requires VMware Tools to be installed in the guest operating system.
  8. Uplinks:-
    Uplinks are the Physical Adapter on the ESXi host which provides the connectivity to the outside Physical Network . It is also referred as vmnic. You can add maximum 32 uplinks to a single vSwitch.
