what differences between Link Aggregation LACP and Teaming from vmware perspective


what differences between Link Aggregation LACP and Teaming from vmware perspective

we have 4 physical servers every server has 2 physical interfaces 10 G speed

i want to configure on of them for VSAN traffic and the other for the other traffic

so the question is

what the best configure teaming or LACP

and which configuration will provide load balance and fail over for VSAN traffic

If you are using Switch or any other network device, that should be LACP enabled so that LACP will be up.

Teaming is another same term in windows which is a group of NIC, for that i believe you don't need to configure switch connected to the server.

You can achieve load balance in lacp by giving source and destination mac address. There are few other ways of load distribution in such combinations.

LACP is handled by the physical switch configuration, Teaming Policies define how the Host handles the traffic.

ESXi teaming policies and configuration affect outbound traffic only!

Answer - you need both!

what really confuse me that vmware offer something called

link aggregation group (lag)

so i thought i will configure the physical switch ports as LA

then i will create on the VDS LAG and that it .

but now as i understand from Andrew

the step must be like this

1- on the physical switch level configure the ports for LA then connect them to the physical hosts interfaces
2- create VDS and assign hosts and interfaces
2- create DV port groups
3- configure teaming and fail-over policies
so if i do theses steps i will have load balance and fail-over between the VSAN traffic interface and the other traffic interface or not . if i will not get load balance no problem but fail-over very important  

so in such case i don't need to create and configure any LAG on vcenter

please check the attaches file and advice if i have to forget about link aggregation group (lag)
This is a great question and I to have been confused by the difference between LACP, LAG etc and the follow article has helped  


In short a LAG is just a name for a grouping of NIC's and LACP is the 'protocol' they automatic negotiates a sets up a LAG if I am reading everything correctly
