Server virtualization is the masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users. The server administrator uses a software application to divide one physical server into multiple isolated virtual environments. Vmware ESX offers tremendous functionality with virtualization, dynamic resource load balancing, and failover. This book delves into aspects of virtualization and is designed for both the beginner and the advanced administrator. The book begins with the requirements and the hardware required by ESX Server. It goes on to look at the differences between ESX version 3.x.x. and ESX version 2.5.x.x. There are also chapters on: Installation; Auditing, monitoring and securing; Storage with ESX; Effects on operations; Networking; Configuring ESX from a host connection; Configuring ESX from a virtual centre or host; Virtual machines; Dynamic resource load balancing; and Disaster recovery and backup. |
