VSphere 6 Networking Deep Dive

Overall rating: 4.85 Instructor: 4.91 Materials: 4.83 more …

Every hypervisor software (including VMware ESX/vSphere, Hyper-V and Xen) has to include a networking component to enable virtual machines running on the hypervisor host to communicate with the outside world. VMware developers decided to depart from the established networking architectures and create an innovative virtual switch implementation. The vSwitch behavior can cause interesting network-side integration challenges; to resolve them, you have to understand how VMware networking works (and grasp their proprietary terminology).

Created by Ivan Pepelnjak, an internetworking and SDN expert, the vSphere 6 Networking Deep Dive webinar explains the details of vSphere networking, the design and deployment principles, and the details of advanced networking technologies and new features introduced in vSphere 5.x and vSphere 6.0.

Target Audience

If part of your daily job includes vSphere network connectivity, be it on the server or networking side, you simply have to attend this webinar, regardless of whether you’re a network architect or an implementation guru.

To attend this webinar, you should be familiar with the concepts of routing and bridging (if you’re a networking engineer, CCNP-level knowledge is highly recommended) and the fundamentals of server virtualization. Data Center 3.0 webinar is the ideal means of acquiring the prerequisite knowledge.

Delivery Format

The vSphere 6 Networking Deep Dive is a 6-hour technical deep dive available as a set of downloadable MP4 videos that you can buy; we can also organize an on-site event, where the topics of this presentation are combined with in-depth discussion of other Data Center networking topics that apply to your network.

About the webinar

Ivan does a great job explaining things under the hood difficult to find on other courses or books.

Marcos Cotomacio
The webinar was consise, its material not dumbed down, there were pearls of knowledge in there which expanded by understanding of ESX and gave me more than a few "aha!" moments, overall well worth the money and I would strongly recommend the webinar for anyone wanting a better understanding of VSphere 6 networking.

The course is worth the money and time for sections "uplink redundancy & load balancing" and "VLAN based virtual networks" alone.
John Ellis
webinar covers the topic over and above anything found in the vendor literature.

About the materials

I would love to see a VMware Clustering Deep Dive series.
Marcos Cotomacio
I am studying for my vSphere 6.0 certification so the webinar was very useful and helpful in my understanding.

The session also covered certain design options, which I found very helpful.

The quality of the video was great as usually Ivan. Could you please cover: protocol support between vSwitch and dvswtich, diff between dvswitch and hyperv networking

Another great deep dive content from @ioshints about vSphere 6 Networking. Awesome as usual!!
