NEC Express5800 Fault Tolerant Virtual Server Quick Start Guide 2This Guide makes the following assumptions about the environment into which you deploy the FT Server:• You do not have any other servers running Windows on your network. (You can have other Windowsservers on your network, but they are not required.)• You are installing Virtual Server 2005 R2 SP1 on Windows Server 2003 R2.• Your servers are members of an Active Directory environment.• You install Microsoft Exchange Server 2003 Service Pack 2 (SP2) or later.• You configure Exchange Server 2003 as a stand-alone server, not as part of a Windows cluster.• You install the Microsoft Virtual Machine PCI SCSI Controller driver on the guest operating system.• You do not enable the virtual hard disk Undo feature.Guide ScenarioThe scenario for the Guide includes three physical servers that provide infrastructure and application services.Figure 1 shows the initial environment.Figure 1: Initial environment.You will deploy virtual machines to replace these physical servers. This enables you to use Virtual Server toaddress cost, reliability, management, and performance issues.The virtualization solution uses three virtual machines (domain controller, file server, and email server) whichwill run on the FT Server.Figure 2 shows the target virtual environment.
