Chapter 2: Planning and Installing ESX Server

Understand ESX Server compatibility requirements. ESX Server has tight restrictions with regard to supported hardware. VMware is the only company that provides hardware drivers for the VMware-supported hardware. The compatibility lists provided by VMware are living documents that will continue to change as new hardware is approved.

Master It You want to reconfigure an existing physical server as an ESX Server host.

Solution Review the ESX Server Systems Compatibility Guide to identify if the existing server is compatible with ESX Server.

Plan an ESX Server deployment. A great deal of detailed planning and projecting is required to deploy a scalable virtual infrastructure.

Master It Your company wants to achieve the greatest ROI while maintaining high performance and availability levels. You need to produce a report that details the virtual infrastructure hardware specifications and costs.

Solution For the greatest ROI, the server specifications for each ESX Server host should maximize the number of cores per slot as well as the speed of each core. Physical memory should be maximized to provide ample room for current, future, and failover virtual machines.

Install ESX Server. ESX Server is a fairly straightforward installation process with only one or two details to pay close attention to.

Master It You need to reinstall ESX Server and want to be sure that inadvertent data loss cannot occur. The ESX Server will boot from local disks.

Solution Disconnect the new ESX Server from the storage area networks to prevent the discovery of existing LUNs that might contain data.

Perform postinstallation configuration. Once the installation of ESX Server is complete the configuration can be tweaked to meet the needs of the organization.

Master It After installing ESX Server, the web-based management page is returning a ‘‘page not found’’ error.

Solution Use the esxcfg-nics and esxcfg-vswitch commands to identify and edit the Service Console NIC association.

Master It Your department heads have defined a company policy mandating the installation of antivirus software into the Service Console. Additional software might be installed at a later date.

Solution Adjust the amount of RAM allocated to the Service Console. Increase it to the maximum value of 800MB.

Install the Virtual Infrastructure Client (VI Client). The Virtual Infrastructure Client is a flexible management tool that allows management of an ESX Server host directly or by connecting to a VirtualCenter installation.

Master It You want to manage the ESX Server hosts from your administrative workstation.

Solution Install the VI Server host home page or the VirtualCenter home page.
