Planning a Deployment Remotely Storing Files from an Active/Active Exchange Cluster The Feature Pack supports one active/active Exchange cluster, as shown in Figure 1.7. In the supported configuration, both Exchange servers in the cluster are active and access the Windows Storage Server computer at the same time. If one of the cluster nodes fails, the storage group operations of the failed node are handled by the other node, thereby preventing loss of service. A dedicated Gigabit Ethernet connection is recommended between each Exchange 2003 server and the Windows Storage Server computer. A dedicated Gigabit Ethernet connection is either a direct point-to-point connection, or is implemented through a switch that supports virtual LANs (VLANs). A separate connection to the public network is required for access to Active Directory and, optionally, to provide client access for general-purpose file sharing. Figure 1.7 Topology with One 2-Node Active/Active Exchange Server Cluster Planning for Security Moving Exchange databases and transaction logs to a Windows Storage Server computer requires the Exchange server to access its data over a network connection. It is therefore important to verify the security of that connection. A dedicated Gigabit network for Exchange traffic is strongly recommended to help prevent network sniffing of Exchange data. Additionally, the Server Message Block (SMB) share used to host the Exchange databases and transaction logs on the Windows Storage Server computer must be locked down to ensure data security. Limiting access to this share to the minimum number of administrators, backup operators, and Exchange servers required is strongly recommended. Important SMB shares that are created using the Win32 user interface grant Read permissions to the Everyone group by default. To ensure data security, this permission setting must be removed on shares that are used to host the Exchange databases and transaction logs.
