vCloud Director 9.5 Cross-VDC Networking Video Walkthrough and Discussion

Over the past few weeks, Wissam Mahmassani, Abhinav Mishra, and I have created a few walkthrough videos on setting up Cross-VDC networking inside of vCloud Director 9.5.

 

Unfamiliar with Cross-VDC networking in vCD? Check out this series of blog posts that review the capabilities and design considerations:

Intro and Use Cases

Getting Started with Cross-VDC

High-Level Provider Design

Design Considerations and Conclusion

 

The intent of these videos is to discuss setting up Cross-VDC networking in vCloud Director but also have a live chat on items we’ve learned along the way with working with it. Quite frankly, it was an open discussion between the team on the inner workings on vCD/NSX and what our development team has done in the backend.

 

vCloud Director 9.5 Cross-VDC Networking Video Walkthrough

 

In the first video, we discuss the pre-requisites before we can start configuring vCloud Director for Cross-VDC networking. In essence, the assumption is cross-vCenter NSX has already been established and we have the primary and secondary NSX managers registered.

 

Next, we review the concept of creating a Datacenter group and what are the different egress options. This is very important as it explicitly controls how traffic exits the overlay environment.

 

Here, we discuss how BGP weights control our active/passive egress points and what vCD automates in the backend. The key is this is all done without provider/tenant configuration – vCD automates this process.

 

As a final wrap-up of the BGP weights, we review creation of the stretched networks inside of vCloud Director along with operational management inside of the vCD H5 UI.

 

Last of all, we demonstrate testing of Cross-VDC and failover of my “Daniel-App” between the two sites. What’s interesting is the ability to migrate egress points without any loss of connectivity. Unintended failover is managed by BGP weights, which the default timer is 60 seconds and could be revised if required.

As stated before, this shows the requirement of having a mirror Edge configuration, especially for NAT configuration and failover testing between sites.

 

This was a fun experience with the team while reviewing and having open discussions on Cross-VDC networking. We are hoping these are valuable for those of you that are interested in bringing this as a new service inside of vCloud Director.

 

Thanks!

-Daniel Paluszek

Device X is not listed on the vSAN Compatability Guide, can I still use it?

Advertise here with BSA


I get this question almost daily, and I am pretty sure I have said this various times, but just in case it wasn’t clear I figured I would share the answer to the question whether a device should be used in a vSAN cluster when it is not listed on the vSAN Compatibility Guide? if you have not looked at the components variant of the VCG for vSAN please take a look here: http://vmwa.re/vsanhclc. Of course we also have an easier route, which is the ReadyNode VCG. But some may want to tweak based on performance, cost etc. I get that, and so does VMware, that is why we have listed all supported and tested components. Can you use a device which is not listed, sure. Will VMware support the environment? Maybe. Should you use a device which is not listed? No!

So let’s be clear and let’s answer the two most asked questions:

  • Device X is not listed on the vSAN Compatability Guide, can I still use it?
    • No, you should not. If any problem arises chances are you will not get the support you need as a result of an unsupported configuration. Sure, usually VMware Support will do their best to help, but if it appears the unsupported device is causing the problem then it becomes difficult. Please do not use devices which are not listed
  • Device X is listed with Firmware version Y, but the OEM says I should use Z, what to do?
    • Ask the OEM why the version is not listed on VMware’s VCG website. Vendors are responsible for certifying components and the software (drivers / firmware) associated with it. If it is not listed then it has either not been submitted yet, it has not been tested, or it has not passed the test. Please only use tested and listed versions, only exception is when both VMware GSS and the OEM points you to a new version.

Hope that helps,
