In this blog article I will first give you some history of the NSX product and how it evolved to the current product that we all know today. Next I will explain the security use case for NSX. And show you step by step how to implement this in your environment.

A bit of history
In 2012, VMware acquired a company called Nicira. One year later VMware launched of the first NSX product from to the public. One year later in 2013 VMware launched NSX for vSphere (NSX-V). NSX-V came with its limitations. To name a few It was tied into vCenter and it was not possible to create multi-tier routing. In 2016 came VMware launched NSX 1.0 which later evolved into NSX Datacenter. Now fast forward to January 22 of 2022, on this day VMware release NSX for Datacenter version 3.2.0.1. This release came with a long list of improvement on his predecessor. The migration and upgrade assistance is very much improved to allow this version to operate in a wide variation of environments. Another big change is the launch of the Kubernetes bases NSX Application Platform. Lees verder

How to place a VMware vSphere ESXi host on Nutanix in maintenance mode

Download Nutanix Logo in SVG Vector or PNG File Format - Logo.winePlacing a VMware vSphere ESXi host in maintenance mode works the same whether the VMs run on vSAN or other types of attached storage. But if the VMs are running on vSphere on a Nutanix cluster the process of placing a host into maintenance mode does work a little different. This is because of the way Nutanix is working together with VMware vSphere ESXi. On every VMware vSphere ESXi host on Nutanix, there is a VM called Controller Virtual Machine (CVM). This VM controls and managed the storage usage. All the storage IO for a host goes through that CVM VM. Lees verder
