This document provides an overview of VMware virtualization components and features. It discusses ESXi and vCenter Server communication, vSphere HA which restarts VMs on failure, vMotion for live migration, and Storage vMotion for live storage migration. The document also outlines VMware vSphere licenses and editions and asks how to provide first line support.

About Virtual Machines
A virtual machine is a software computer that, like a
physical computer, runs an operating system and
applications.
• Operating system
• VMware Tools™
• Virtual resources like:
– CPU and memory
– Network adapters
– Disk controllers
– Parallel and serial ports

Benefits of Using Virtual Machines
Physical Machines:
Difficult to relocate
• Moves require downtime
• Specific to physical hardware
Difficult to manage
• Requires physical maintenance
• Hardware failures cause downtime
Hardware has limitations
• Hardware changes limit application support.
• One-to-one relationship between application and
server.
Virtual Machines:
Easy to relocate
• Encapsulated into files
• Independent of physical hardware
Easy to manage
• Isolated from other virtual machines
• Insulated from hardware changes
Provides the ability to support legacy
applications

32. Storage vMotion
• Relocate running VM from one datastore to
another datastore with zero downtime
• Relocate across different storage types
• Change VM disk format (thick or thin)
