Chapter 1

Introducing VMware vSphere 4

VMware vSphere 4 builds upon previous generations of VMware virtualization products, becom-

ing an even more robust, scalable, and reliable server virtualization product. With dynamic

resource controls, high availability, unprecedented fault tolerance features, distributed resource

management, and backup tools included as part of the suite, IT administrators have all the tools

they need to run an enterprise environment ranging from a few servers up to thousands of servers.

In this chapter, you will learn to:

◆ Identify the role of each product in the vSphere product suite

◆ Recognize the interaction and dependencies between the products in the vSphere suite

◆ Understand how vSphere differs from other virtualization products

Exploring VMware vSphere 4

The VMware vSphere product suite includes a number of products and features that together

provide a full array of enterprise virtualization functionality. These products and features in the

vSphere product suite include the following:

◆ VMware ESX and ESXi

◆ VMware Virtual Symmetric Multi-Processing

◆ VMware vCenter Server

◆ VMware vCenter Update Manager

◆ VMware vSphere Client

◆ VMware VMotion and Storage VMotion

◆ VMware Distributed Resource Scheduler

◆ VMware High Availability

◆ VMware Fault Tolerance

◆ VMware Consolidated Backup

◆ VMware vShield Zones

◆ VMware vCenter Orchestrator

Rather than waiting to introduce these products and features in their own chapters, I’ll intro-

duce each product or feature in the following sections. This will allow me to explain how each
