331 Figure 2 illustrates the four-node, active/passive Exchange Server 2003 cluster. Figure 2 Four-node active/passive Exchange Server 2003 cluster The following sections provide the recommended software, hardware, and storage requirements for an Exchange Server 2003 active/passive four-node cluster. 332 Software Recommendations In this scenario, all four nodes in the cluster are running Windows Server 2003, Enterprise Edition and Exchange Server 2003, Enterprise Edition. Additionally, each node is connected to a DNS server configured for dynamic updates. Hardware Recommendations In this scenario, the following hardware configurations are recommended. Server hardware  Four 1 gigahertz (GHz), 1 megabyte (MB) or 2 MB L2 cache processors  4 gigabytes (GB) of Error Correction Code (ECC) RAM  Two 100 megabits per second (Mbps) or 1000 Mbps network interface cards  RAID-1 array with two internal disks for the Windows Server 2003 and Exchange Server 2003 program files 333  Two redundant 64-bit fiber Host Bus Adapters (HBAs) to connect to the Storage Area Network Local area network hardware  Two 100 Mbps or 1000 Mbps network switches (full duplex) Storage Area Network hardware  Redundant fiber switches  106 disk spindles (Ultra Wide SCSI) with spindle speeds of 10,000 RPM or greater  256 MB or more read/write cache memory Storage Configuration Recommendations In this scenario, the following storage configurations are recommended: Storage groups and databases  Three storage groups per Exchange Virtual Server 334  Five databases per storage group Disk drive configuration Table 2 lists the recommended disk drive configuration. For more information about this and other disk drive configurations, see "Drive Letter Configurations" in the guide Planning an Exchange Server 2003 Messaging System (http://go.microsoft.com/fwlink/?LinkId=47584) Table 2 Disk drive configuration for a four-node active/passive cluster containing three Exchange Virtual Servers Node 1 (EVS1 active) Node 2 (EVS2 active) Node 3 (EVS3 active) Node 4 (passive) Disk 1: SMTP/MTA Disk 8: SMTP Disk 15: SMTP Disk 22: Quorum Disk 2: SG1 databases Disk 9: SG1 databases Disk 16: SG1 databases Disk 3: SG1 logs Disk 10: SG1 logs Disk 17: SG1 logs 335 Node 1 (EVS1 active) Node 2 (EVS2 active) Node 3 (EVS3 active) Node 4 (passive) Disk 4: SG2 databases Disk 11: SG2 databases Disk 18: SG2 databases Disk 5: SG2 logs Disk 12: SG2 logs Disk 19: SG2 logs Disk 6: SG3 databases Disk 13: SG3 databases Disk 20: SG3 databases Disk 7: SG3 logs Disk 14: SG3 logs Disk 21: SG3 logs Storage Area Network disk configuration  SMTP/MTA drives RAID-(0+1) array consisting of four spindles. (3 EVSs × 4 disks = 12 disks.) 336  Storage group log drives RAID-1 array consisting of two spindles. (3 EVSs × 3 storage groups × 2 disks = 18 disks.)  Database (.edb and .stm files) drives RAID-(0+1) array consisting of eight spindles. (3 EVSs × 3 storage groups × 8 databases = 72 disks.)  Quorum disk resource drive RAID-1 array consisting of two spindles (2 disks). Total shared disk spindles is 104. Deploying a New Exchange Server 2003 Cluster This section provides information about how to deploy a new Exchange Server 2003 cluster in your organization. The procedures referenced this section are applicable for any cluster configuration, from an active/passive cluster with two to eight nodes to a two-node active/active cluster with one or two nodes. Specifically, this section will guide you through the following steps: 1. Preparing Active Directory for Exchange Server 2003. 337 2. Installing Exchange Server 2003 on each node. 3. Creating the Exchange Virtual Servers. Step 1: Preparing Active Directory for Exchange Server 2003 Preparing Active Directory for a cluster installation resembles preparing Active Directory for non-clustered servers. Step 1 includes the following tasks: 1. Run ForestPrep. 2. Run DomainPrep. Running ForestPrep Before you install Exchange Server 2003 anywhere in the forest, you must extend the Windows Active Directory schema. To accomplish this task, you must run ForestPrep. 338 Note: Running ForestPrep is required only if you are installing Exchange Server 2003 for the first time in your organization. If you already installed Exchange Server 2003 in your organization, you do not have to run ForestPrep. For detailed steps about how to run ForestPrep, see How to Run Exchange Server 2003 ForestPrep. Note: During the ForestPrep process, you will enter the name of the user or group who is responsible for installing Exchange Server 2003. This account must be a domain account that includes local administrator privileges on the cluster nodes. The account you specify will also have permission to use the Exchange Delegation Wizard to create all levels of Exchange Server 2003 administrator accounts. Running DomainPrep You must run DomainPrep for each Windows 2000 or Windows Server 2003 domain in which you want to install Exchange Server 2003. 339 However, before you can run DomainPrep, ForestPrep must finish replicating the schema updates. Note: Running DomainPrep is required only if you are installing Exchange Server 2003 for the first time in your domain. If you already installed Exchange Server 2003 in your domain, you do not have to run DomainPrep. For detailed steps about how to run DomainPrep, see How to Run Exchange Server 2003 DomainPrep. Step 2: Installing Exchange Server 2003 on Each Node After you extend the schema with ForestPrep and prepare the domain with DomainPrep, you are ready to install Exchange Server 2003 on the first cluster node. Step 2 includes the following tasks: 1. Make sure that the Cluster service is running on each node. 2. Install and enable the required Windows services. 340 3. Install Microsoft Distributed Transaction Coordinator (MSDTC). 4. Run Exchange Server 2003 Setup. However, before you perform these tasks, familiarize yourself with the requirements necessary for installing Exchange Server 2003 on cluster servers (Table 3). .
