Paul Bryant One of the things I like about NSX-T is the ability to deploy Tier-1 and Tier-0 routers. The T0 is the gateway that bridges the virtual world to the physical world. Below you will find a screenshot of the logical architecture followed by a step by step process to deploy a T0 router in your … Explore: NSX-T – Deploying Tier-0 (T0) Router
From time to time you may encounter an error where your VxRail node goes into a device missing state in VxRail manager but is operating normally in vCenter. The main culprit behind this is typically the PTAgent. The PTAgent exists to poll hardware information on a node every few minutes using ipmi. Assuming there isn’t … Explore: VxRail PTAgent Troubleshooting – Device Missing State

Another instance you may be you are wanting to shrink a large cluster into two smaller manageable … Explore: How to remove a VxRail 4.7 Node from…
As I continue my blogging series on deploying NSX-T 2.4 in your environment, my next topic will be Domains. This will be a quick blog as there is not a lot about setting up Domains. Domains will pop up a lot when configuring NSX-T. They are great for logically grouping a collection of workloads and … Explore: Deploying a Domain in NSX-T
Many asked so here it is. A how to guide on leveraging Tags and Security Groups to apply Firewall Policies/Rules to groups of VMs. My main goal for this article is to simplify a complicated 2.4 Admin Guide, which does not spell out how to do this in step by step options. The Admin Guide … Explore: NSX-T Applying Micro-Segmentation with Tags
There may be instances when you want to leverage NSX-T for NAT services and not an external NAT services. Thanks to the simplified management of NSX-T deploying these services is easy. Terms:Source NAT (SNAT): translates a source IP address of outbound packets so that packets appears as originating from a different network Destination NAT (DNAT): … Explore: Deploying NAT Services on NSX-T
Lately, I have had people messaging asking to help them troubleshoot their environment. Everything from random performance impacts to my SQL DBA says I have a disk IO issue. I thought I would take the time to post a few helpful ruby shell commands I use to help me keep an eye on my own … Explore: Useful Ruby Shell vSAN Commands
Over the past couple years I hear the term Micro-Segmentation over and over and over and over again as the benefit of NSX & software defined networking. I thought I would take a moment to write about four benefits of NSX-T I’m witnessing in my environments that bring value add on top of Micro-Segmentation. 1. … Explore: Four Benefits of NSX-T Not Named Micro-Segmentation
I wanted to take a moment and provide a link to the new feature release of NSX-T 2.4. This has been a major release with a re-architecture of the NSX-T components.

Legacy walkthrough — originally published April 3, 2019. The screenshots and VxRail port-layout examples below reflect the environment used at that time; they are not a universal design for current deployments. Verify vCenter, ESXi, and distributed-switch compatibility, licensing, uplinks, VLANs, and the supported VxRail network design before applying these steps.

VMware has just released a new document to perform a migration from NSX-V to NSX-T leveraging the NSX-T Datacenter Migration Coordinator. Click to access nsxt_24_migrate.pdf Happy reading.
Prerequisites The VMs must be hosted on hypervisors that have been added to the NSX-T Data Center fabric. The fabric nodes must have NSX-T Data Center management plane (MPA) and NSX-T Data Center control plane (LCP) connectivity. The fabric nodes must be added to a transport zone. A logical switch must be created. Steps: In … Explore: Connecting a Virtual Machine to a NSX-T Logical…
When I first tackled NSX-T, like many, I was concerned about IO/Packet flow. Based on feeding my own curiosity while preparing my production environment for NSX-T I decided to write this article. Below you will find high level overview of components and the two tier routing topology. Routing can be defined in the following directions: … Explore: NSX-T Routing 101
It feels like I cannot go a week without being asked the question of, “What is my real capacity on vSAN/VxRail?” Followed by we just cannot get our capacity planning correct and we are determining how much more capacity to grow our cluster by. I thought I would perform a back to basic vSAN math … Explore: VxRail / vSAN Capacity Math Made Easy
NSX-T Manager Controller provides the graphical user interface (GUI) and the RESTful API for creating, configuring, and monitoring NSX-T components, such as logical switches. NSX-T Manager Controller implements the management plane for the NSX-T infrastructure. It provides an aggregated system view and is the centralized network management component of NSX-T. It provides a method for … Explore: NSX-T Component Overview
This is my fourth and final installment of this series. These steps were taken by me to failover and failback multi-million dollar datacenters in as easy as 4-clicks. At this point we should have our SDDC deployed and linked back to our onprem. VR/SRM should be deployed both onprem and in the SDDC. All site … Explore: Part 4. DRaaS – The four click failover…
Recently, I have been getting a lot of questions around how to build vSAN for high performing workloads. This article is intended to cover hardware differences, slack space, what is vSAN namespace, object, component, Raid-1 vs Raid-5/6, and stripe width, which all can impact performance. Please keep in mind I am not covering dedup/compression overhead … Explore: Performance Tuning your vSAN / VxRail Environment
I wanted to cover real quick creating a custom storage policy on vSAN, which even on a VxRail is done in vCenter. House keeping items:Raid 1 mirror is where you write a complete replica of the object. This is the highest performance protection you can apply to an object. Since it is a complete replica … Explore: Create a new vSAN Storage Policy in vSphere…
