To the users on the network, nothing appears to have changed as
virtualizing the physical servers does not change anything about the
functionality of the server except the hardware that it is running on.

Problem
Dat-A-Syst has a couple of aging tower servers running Windows Server 2003 and
Windows Small Business Server 2003 that needed a hardware refresh, but operating
system was running fine other than the aging hardware.
Solution
Solstice Data Group installed a new HP Proliant Rack Mount Server with Windows
Server 2008. Using VMWare Server Edition, the two older servers were converted into virtual machines on the new server. The client did not experience
any downtime through the conversion as it was performed over the weekend.
By using Windows Server 2008 as the 'host' machine and using Storage Craft's
Shadow Protect Server Edition software. We are able to create continuous
incremental backups to a workstation over the network. The backup workstation
then sync's the backup images with external hard drives that are rotated and
taken off-site in case of catastrophic event.
Uses For Your Business
Virtualization is slowly working it's way into the Small to Medium size business
arena. Most server implementations are now performed in a virtual machine using
Microsoft's Hyper-V or VMWare. The reasons for doing a virtual install is mainly
two fold:
1) You can easily move the server from machine to machine without 'marrying' the
operating system to the hardware that is running the machine. This means that
restoring a server to a completely different hardware can take minutes instead
of hours or possibly days.
2) Most server hardware is completely under utilized and using virtualization
will allow you to install two to five virtual servers (depending on their load
and the physical performance of the host machine). This consolidation effect
saves power and cooling costs as well as the maintenance of seperate physical
servers.
