VMworld 2017 Please vote for my sessions!

This has been one of my goals for 2017 where I wanted to submit at least one paper for VMworld 2017. I am glad that I could come up with two sessions and Arup on third session. All sessions will be presented by both of us.

The VMware content team just announced that public voting is now open and I would request you to spend a couple of minutes of your time to vote for my sessions and other which you would like to see in the upcoming VMworld 2017.

Session Titles:

Below are the details of the abstracts submitted for each session and what can be expected. Click on any of the session titles to cast your vote.

I sincerely hope that you will spend a couple of minutes of your time to vote for the sessions if you think these sessions would help you. Thank you very much.

Hope to make it to my first VMword in 2017! 

10GE Testing – Multi-NIC vMotion

Had access to some 10GE NICs and therefore decided to do some performance testing and try out Multi-NIC vMotion.

Intel X520-DA2

The 10GE NICs were Intel X520-DA2 and I used SFP-H10GB-CU3M to connect directly to both hosts as I do not access to a 10GE switch at the moment.

Without reading any documentation, I tried add both 10GE ports into a vSwitch and vMotion does not work. After googling and reading the documentation, we actually have to separate the 10GE ports into their own vSwitches before the Multi-NIC vMotion will work.

Conclusion:
Although with Multi-NIC, vMotion seems to perform faster as compare to Single-NIC, however, the difference is not significant. This is probably due to the size and the number of VMs I used for the vMotion tests.

It was noticed that there was load sharing of vMotion traffic between the 2 10GE ports as you can see from the network performance graphs. Using single-NIC, network usage is about 200MBps while multi-NIC scenario, network usage is about 100MBps per NIC which is 50% of that single-NIC.
