Getting Started with ESX

Get started with ESX quickly with this information about installation and initial setup. Follow the procedures

included here to install and setup a basic inventory for a single-host virtualization environment. After your

host is set up with a working virtual machine, you can install vCenter Server and explore a multiple-host

virtualization environment.

This information is for experienced Windows or Linux system administrators who will be installing VMware

ESX to deploy virtualization for the first time. Specifically, it is for users who meet the following requirements:

nDo not yet have the ESX software installed

nDo not yet have the vSphere Client or VMware vCenter Server installed.

Getting Started Tasks

The getting started tasks take you from initial setup of a new virtualization host to a working virtual machine.

After you have a host and functional virtual machine, you can setup a managed host environment with vCenter

Server.

Getting started with ESX includes the following tasks:

nInstalling ESX and adding the host to your network

nInstalling the vSphere Client and connecting to the ESX host

nDeploying and running a virtual machine

Completing the getting started tasks sets up the single-host management system for virtualization as shown in

Figure 1.

Figure 1. Basic Single-Host Management System

After the initial setup of ESX, you can deploy vSphere 4.0 with vCenter Server to manage multiple hosts.

ESX Installation

Install ESX to get started with running virtual machines. The machine running ESX virtualization software

will act as a host in your virtual infrastructure.

Hosts provide CPU and memory resources, access to storage, and network connectivity for virtual machines

that reside on them.

Prerequisites for Installing ESX

Before you begin the installation procedure, ensure that the host meets the prerequisites.

The prerequisites are as follows:

nMake sure the host has a supported network adapter.

ESX Hardware Requirements

Using ESX requires specific hardware and system resources.

64-Bit Processor

nVMware ESX 4.0 will only install and run on servers with 64-bit x86 CPUs.

nKnown 64-bit processors:

1 Use the BIOS to set the server to boot from the DVD.

a Reboot the machine.

b Press the key required to enter your machine’s BIOS setup or boot menu.

This key is often a function key or Delete.

c Set the CD-ROM drive as the first boot device.

2 Select Install ESX in graphical mode.

A series of installation messages scroll past until the Welcome page appears.

3 Click Next to continue.

4 Select I accept the terms of the license agreement and click Next.

You cannot install this product unless you accept the license agreement.

NOTE If the alignment of the license agreement screen is skewed to the left, you might need to auto-adjust

your host monitor.

5 Select your keyboard type from the list and click Next.

6 Select whether to install custom drivers with the ESX installation.

You might need custom drivers if your system is not listed in the Hardware Compatibility Guide and has a

network or storage device that was not originally compatible with ESX 4.0.

nSelect Yes and click Add to install custom drivers. The installer prompts you to insert the media

containing the custom drivers. After you add the custom drivers to the list, the installer prompts you

to reinsert the ESX installation DVD and continue with the installation. Click Next to continue.

nSelect No if you do not need to install custom drivers. You can install custom drivers after the ESX

installation is complete, using other command-line and GUI tools available to you, such as the vSphere
