A couple of useful links

Some time ago AWS Partner Netwok Blog published a couple articles that cover AWS Virtual Private Cloud (VPC) networking in great detail, with a bunch of links to further info. Best of all, they were written by a networking person, for readers with networking backgroun in mind.

While we all know how to use your favourite search engine, a little promotion sometimes goes a long way. 🙂 So, here they are:

Happy reading! 🙂

Validating HW VTEP deployment for integration with NSX-v

This post is next in series on using HW VTEPs with NSX-v. You can find earlier posts here: 1, 2, and 3.

Today we’ll look at a couple of choices you’ll need to make when deploying Brocade’s HW VTEP, and then check if our configuration is correct before linking it with NSX-v next time.

Planning deployment of a Hardware VTEP with NSX for vSphere

In a couple of previous blog posts, we’ve looked at the use cases for HW VTEPs. Now, let’s start digging a bit deeper.

In this instalment, we’ll have a look at what things you need to think about when planning your Hardware VTEP deployment. While I’ll be using Brocade VCS as the HW VTEP for this post, some of this info should be applicable to other Vendors’ solutions.

VMworld 2015 presentation recordings have been published

..which includes the session on NSX Troubleshooting methodology that I presented.

Start page:

http://www.vmworld.com/en/sessions/2015.html

To find my session called “NET5488 – Troubleshooting Methodology for VMware NSX”, search for “NET5488”. Both US and Europe versions are available.

In this session, I walk through how NSX-v’s VXLAN-based logical switching works, what commands you can use to see what’s happening under the covers, and how to make sense of what you’re seeing. This should provide a good base for your troubleshooting practice.

(Hat tip to ‪@ericsiebert and ‪@scott_lowe‬ for the info that sessions are now online, free for all)


Do I need a hardware VTEP for my NSX for vSphere?

VMware NSX for vSphere has been shipping beta support for hardware VTEPs since version 6.2.0, with General Availability (GA) coming in the next few months. With this in mind, I thought it would be useful to provide an overview of HW VTEP’s use cases and considerations.

My presentation from VMworld 2015

#NET5488: Troubleshooting Methodology for VMware NSX (for vSphere, v6.2):

I designed the pack to be read, so hopefully you find it useful without the recording. For those who have attended VMworld, both US and Europe sessions were recorded. You should be able to watch them on vmworld.com.

Not sure which one (US or EU) went better, to be frank. 🙂


Good NSX resources

A few days ago while chatting with a customer who is getting ready to plan their virtual infrastructure with NSX, I realised they did not know that documentation for the NSX vSphere has been publicly available for a while.

Also, turns out they haven’t seen the brilliant collection of NSX resources hosted on VMware’s NSX web site, including Network Virtualisation Design Guide, which, well, pretty much covers all of the important considerations for an NSX deployment.

So, while they are a just quick google search away, here’s the links:

NSX Resources (see the design guides in the “Technical Resources” section):
http://www.vmware.com/au/products/nsx/resources

NSX vSphere Documentation:
http://pubs.vmware.com/NSX-6/index.jsp

NSX Support Center:
https://www.vmware.com/support/nsx.html – Includes all documentation guides and Release Notes

NSX VMTN Documents:
https://communities.vmware.com/community/vmtn/nsx/content?filterID=contentstatus%5Bpublished%5D~objecttype~objecttype%5Bdocument%5D – Guides, whitepapers, etc

P.S. While this post isn’t really intended as a collection of useful NSX links, I think I’ll likely be updaing it if I come across any items of a comparable caliber.
