Howto VMWare ESXi Installation Steps

Introduction to ESXi

What is ESXi?

In simple term (Not Technical), ESXi is an Operating system just like Microsoft Windows or Linux but it allows you to create Mini Servers on a Physical Host.

Technical Definitions:-


“VMware ESXi is a purpose-built bare-metal hypervisor that installs directly onto a physical server. With direct access to and control of underlying resources, ESXi is more efficient than hosted architectures and can effectively partition hardware to increase consolidation ratios and cut costs for our customers.”


VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware for deploying and serving virtual computers. As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel.”


Before installation of ESXi make sure that you have configured below on/for your Physical Server:-

  1. ILO or iDRAC
  2. VNC/KVM or console access is working
  3. Virtual Media’s can be attached via Console
