VMVware vswitch load balancing methods

Load balancing is one of the most important thing in a virtual world. Because we are using few NICs for receiving & sending a data of multiple virtual machines. There are few policies in vmware load balancing . We will take one by one and lets have a look.

Route based on originating virtual port ID

Example

In this vswitch I have two nics allocated.

And I have three virtual machines as bellows

 

Server A have one Nic,Server B have two Nics & Server C have one Nic.

Route based on originating virtual port ID works like round robin. Server A nic will be use physical vmnic4 for passing the traffic.

Server A first nic will be use vmnic5 and second nic will be use vmnic4

Server C have only one nic and it will use vmnic4.

In this load balancing mechanism it doesn’t measure any other things. That is the main disadvantage of this, but we don’t have to do any modifications to the physical network environment.

Vsphere Private VLAN

Private VLAN is a concept where we can cave multiple VLANS inside on VLAN. It’s a logical separation of a same VLAN.

PVLANS helps us to save no of VLAN ids and ip addresses. Because we can separate same ip subnet into separate portions using PVLANs.

Also this will help us to stop unnecessary communication between virtual machines.

To use VPLAN we need to have distribute switch/es in our VMware environment.

There are three categories in a PLAN as bellows
