Imagine this, you’ve been tasked with implementing micro-segmentation in your vSphere environment. You just deployed and configured NSX-T and the next step is to migrate VMs from their VDS port groups to N-VDS segments. You fire up the vSphere Client and expand the VDS to have a look at the current situation: It’s pretty bad.…

Welcome back! I’m in the process of setting up NSX-T in a stretched cluster environment. In part 1 I deployed the NSX manager cluster and configured the ESXi hosts as NSX transport nodes. The N-VDS was installed on the ESXi hosts and their vmkernel adapters migrated from the VDS to the N-VDS. In this second…
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…
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…
