ESX Server environment. vReplicator is designed to perform replication specifically for

virtual machines (VMs.)

In this manual, you will learn how to install and configure vReplicator. You will also

learn how to use these components:

• Notification

• Alerts

First, some background on the context in which vReplicator was developed.

Virtualization and VMware Overview

As companies and industries grow, their technology needs change. These changes are

often implemented within complex systems running business-critical applications.

Usually there is an increased demand for shared hardware and software resources. To

manage this demand, many companies establish virtual environments. Doing so can

increase an organization’s agility and efficiency while lowering its costs.

Most companies have a number of specialized physical servers and workstations that are

underutilized. Virtualizing such an environment increases and balances utilization by

consolidating the physical machines into a single physical host that runs multiple VMs.

The VMs share the resources—processor, memory, network cards, and disks—of one

physical host. The work that the physical machines did previously continues, but with

greater efficiency. The host runs a layer of virtualization software that manages the

environment. Each VM’s operating system (OS)—usually Windows or Linux—functions

as if the hardware were physical. Guest software can see only x processor, y memory, and

so forth.
