Installing Exchange Server 2007 • Chapter 2 27 Enterprise Edition So what extra benefi ts will you get out of deploying an Exchange 2007 Enterprise edition in your environment? The Enterprise edition of Exchange Server 2007 has been designed for large enterprise corporations. The Enterprise edition has support for: ■ 50 Storage Groups ■ 50 databases ■ No database storage limit ■ Local Continuous Replication (LCR) ■ Exchange 2007 Clustering ■ Single Copy Clusters (SCC) using MSCS ■ Cluster Continuous Replication (CCR) using MSCS Exchange Server 2007 Client Access Licensing Exchange 2003 and earlier versions offered only one type of Exchange Client Access License (CAL), but with Exchange 2007 we now have two types: a Standard CAL and an Enterprise CAL. Standard CAL In addition to the features of Exchange 2003 CAL, the Exchange 2007 Standard CAL provides us with the following: ■ Org-wide policy management ■ Cross-org mailbox search ■ Continuous Replication Technologies ■ Mail-fl ow rules ■ Server roles Enterprise CAL In addition to the features of Exchange 2007 Standard CAL, the Enterprise CAL provides us with the following: ■ Unifi ed messaging ■ Per-user journaling ■ Exchange Hosted Services Filtering ■ Forefront Security for Exchange Server (Microsoft’s antivirus product, formerly known as Antigen) 28 Chapter 2 • Installing Exchange Server 2007 Exchange 2007 Prerequisites Before you begin installing Exchange Server 2007, you should make sure that the computer on which you are installing the product meets the recommended hardware and software requirements. In addition, you should make sure that the Active Directory domain in which you are installing Exchange Server 2007 is confi gured with the correct functional level. The minimum Windows Active Directory functional level for Exchange 2007 is Windows 2000 native mode. If you are installing Exchange Server 2007 into an existing Exchange organization, it is also important to note that the organization should be running in native mode; however, since the purpose of this chapter is to show you how to install Exchange Server 2007 into a clean Active Directory forest, you really don’t need to worry about this now. NOTE Before you get too involved in planning the budget for a transition to Exchange 2007 in your organization, you should be aware of one very important thing. Many of you who have Exchange 2003 deployed in your organizations might very well be aware of the fact that each Exchange 2003 CAL included the right to install Outlook 2003 on the devices for which these CALs were obtained. You probably think this hasn’t changed a bit with Exchange 2007 CALs. Think again, because Exchange Server 2007 Standard or Enterprise does not include the right to install Outlook on devices for which CALs are obtained! This means that your organization might have to wait to make the transition to Exchange 2007 until you’re ready to deploy Offi ce 2007 as well. To read more about this Exchange 2007 CAL change, visit www.microsoftvolumelicensing.com/ userights/ProductPage.aspx?pid=111. IMPORTANT The Exchange Server 2007 32-bit evaluation version is meant to be used in a test environment only and should never be used in a production environment, because it is not supported by Microsoft. The only Exchange Server 2007 component you may use in a production environment is the Exchange 2007 Management Tools (more specifi cally, the Exchange Management Console, the Exchange Management Shell, the Exchange Help fi le, and the Exchange Best Practices Analyzer tool). These can be installed on a 32-bit machine running either Windows 2003 Server with Service Pack 1 (SP1) or Windows XP Professional with Service Pack 2 (SP2). Although the hardware and software requirements are the same, this chapter does not cover how to install an Exchange server into an existing Exchange organization. It also does not go into detail on how you transition from Exchange 5.5, 2000, or 2003 to Exchange 2007. Instead, these topics are covered in Chapter 10. Installing Exchange Server 2007 • Chapter 2 29 Hardware Requirements The hardware requirements for a production Exchange 2007 server are described in the following sections. Processor Exchange Server 2007 exists in both 32- and 64-bit versions, but only the 64-bit version is supported in a production environment. This means that the server hardware on which you plan to install Exchange Server 2007 must have one of the following 64-bit processor types installed: ■ x64 architecture-based processor that supports Intel Extended Memory 64 Technology (Intel EM64T) ■ x64 architecture-based computer with AMD 64-bit processor that supports AMD64 platform Note that the Intel Itanium IA64 processor is not listed, since it is not supported by Exchange Server 2007. NOTE If you are planning to use Exchange Server 2007 for either testing or evaluation purposes, you can use the 32-bit evaluation version. This simply requires an Intel Pentium or compatible 800 megahertz (MHz) or faster 32-bit processor. The Exchange 2007 Evaluation version can be downloaded from www.microsoft.com/exchange. Memory The memory requirements for a 64-bit Exchange 2007 server that is to be deployed in a production environment are 2 gigabytes (GB) of RAM per server. However, bear in mind that those are the minimum requirements. The recommend requirements are: ■ 2GB of RAM per server plus approximately 5 megabytes (MB) of RAM per user mailbox located on the respective server ■ A paging fi le equivalent to the amount of server memory plus 10MB Also be aware that it’s recommended to add additional memory if you’re planning to use more than four storage groups (approximately 2GB per three storage groups). Disk Space Disk space requirements are as follows: ■ At least 1.2GB of disk space on the drive on which Exchange Server 2007 is to be installed ■ 200MB or more of disk space on the system drive 30 Chapter 2 • Installing Exchange Server 2007 When installing the Unifi ed Messaging role on a server, you will also need to allocate an additional 500MB for each Unifi ed Messaging language pack that is installed. Drives A DVD drive isn’t really a requirement, because you can install Exchange 2007 from an attached network drive or even a mounted ISO fi le. Software Requirements In addition to the hardware requirements, Exchange Server 2007 has some software requirements that need to be fulfi lled before you can begin your install. Operating System When planning to install Exchange Server 2007 in a production environment, you will need Microsoft Windows Server 2003 64-bit version with Service Pack 1 or Windows Server 2003 R2 64-bit version. Both Standard and Enterprise Editions are supported by the 64-bit version of Exchange Server 2007, but bear in mind that the Enterprise Edition is required if you are planning on deploying an Exchange 2007 cluster. (This goes for both Single Copy Clusters and Cluster Continuous Replication setups.) If you plan on installing the Exchange 2007 32-bit version (for testing or evaluation purposes), you would need to install the 32-bit version of Microsoft Windows Server 2003 SP1 or Windows Server 2003 R2. SOME INDEPENDENT ADVICE Since Exchange 2007 can be installed on a server running either Windows Server 2003 R2 or Windows Server 2003 SP1 or higher, those of you who deal with Windows 2003 Small Business Server (SBS) are probably wondering whether Exchange 2007 will be supported in the current edition of SBS. Unfortunately, the answer is no. You will have to wait for the next major release of SBS, which will be based on the Windows Longhorn server. Even worse, the next version of SBS won’t be released for approximately six to 12 months after Windows Longhorn server hits the streets. File Format All disk partitions must be formatted with the NTFS fi le system (that’s right, FAT is, fortunately, not supported). This means that all disk partitions holding any fi les or data in the following list should be formatted using NFTS: ■ System partition ■ Partition storing Exchange Server binaries Installing Exchange Server 2007 • Chapter 2 31 ■ Partitions containing transaction log fi les ■ Partitions containing database fi les ■ Partitions containing other Exchange Server fi les Software Required The following software is required for any of the fi ve different Exchange 2007 server roles. Server roles were previously discussed in detail in Chapter 1. ■ Microsoft .NET Framework Version 2.0 ■ Microsoft Management Console (MMC) 3.0 (bear in mind that MMC 3.0 is installed by default when you use Windows Server 2003 R2) ■ Windows PowerShell V1.0 ■ HotFix for Windows x64 (KB904639) NOTE If you haven’t installed .NET Framework 2.0, the MMC 3.0 snap-in, or Windows PowerShell when you launch the Exchange Server 2007 installation program, you will be provided with links to each respective piece of software so that you can install each separately. Required Windows Components Depending on the Exchange 2007 server roles you plan to install, different Windows components are required before doing so. This section lists each role as well as the required Windows components. Mailbox Server The following components are required for the Mailbox server: ■ Enable network COM+ access ■ Internet Information Services ■ World Wide Web Service Client Access Server The following components are required for the Client Access server: ■ World Wide Web Service . Licensing Exchange 2003 and earlier versions offered only one type of Exchange Client Access License (CAL), but with Exchange 2007 we now have two types: a Standard CAL and an Enterprise CAL. Standard CAL In. Server 2003 64-bit version with Service Pack 1 or Windows Server 2003 R2 64-bit version. Both Standard and Enterprise Editions are supported by the 64-bit version of Exchange Server 2007, but bear.
