A stretched cluster architecture facilitates for higher levels of availability and things like inter-site load balancing. It’s a common multisite solution and also part of VMware’s Validated Design for SDDCs with multiple availability zones. Traditionally compute networking in an active-active multisite setup has had its challenges, but with vSAN storage and NSX networking technologies that’s…
Recently a new version of the NSX-T Reference Design Guide was released. This guide, which now covers NSX-T versions 2.0 – 2.5, is a must read for anyone interested in the NSX-T solutions and their recommended design. One of the things you’ll find in the updated guide is a new recommended deployment mode for the…
Welcome back! In part 1 we had a look at some NSX-T management plane failure scenarios and how to recover from them. In this part we continue to investigate NSX-T recoverability at the data plane and more specifically the NSX Edge. Quick note If you ever experience an issue in your NSX-T production environment, the…
With NSX-T 2.5 comes NSX Intelligence 1.0. This component, which is part of NSX Data Center Enterprise Plus, is something I’ve been looking forward to since it was announced. NSX Intelligence adds a powerful analytics engine to the NSX-T platform. It provides workload and network context that is unique to NSX. Application owners and operations…
Like everything else in life, stuff can break in your NSX-T environment too. When that happens it’s important to understand how to get things back on track again. In the following blog articles I’m going through a couple of NSX-T failure scenarios and look at how to recover from them. As usual I’m doing this…

Hi and welcome back. We’re looking into the NSX-T data path and investigating different points at which we can capture network traffic. You may remember from part one that virtual machine “app01” (172.16.2.50) is trying to ping another virtual machine called “web01” (172.16.1.53), but it’s receiving “request timeout”. We’re trying to find out where in the data…
Welcome back! We’re looking at how to gain visibility at different points in the NSX-T data path.
