Contents About the Document This document provides design and configuration guidance for site and server load balancing, Secure Sockets Layer SSL offload and WAN optimization in a Microsoft Exchange Server 2. Cisco multisite data center architecture. An overview of the various Microsoft Exchange Server 2. Audience This document is intended for network engineers and architects who need to understand both the basics of a Microsoft Exchange environment and the design and configuration options for providing advanced network services for Microsoft Exchange Server 2. Document Objectives The objective of this document is to provide customers guidance on how to leverage a Cisco multisite data center design to support a Microsoft Exchange Server 2. The document is not meant to introduce the reader to basic Cisco data center design configurations nor is it meant to be a resource to learn the details of Microsoft Exchange Server 2. The reader must be familiar with the basic Cisco data center concepts and products as well as the basics of Microsoft Exchange Server 2. Microsoft Corporation. The prerequisite knowledge can be acquired through many documents and training opportunities available both through Cisco and Microsoft. Below are a few recommended information resources that readers would find useful in these areas of interest Cisco Connection Online Data Center http www. Cisco Solution Reference Network Designs SRND http www. Microsoft Exchange Server 2. Document Format and Naming Conventions User defined properties such as access control list names and policy definitions are shown in ALL CAPS to assist the reader in understanding what is user definable versus command specific. All commands are shown in Courier font. All commands that are applicable to the section covered will be in BOLD. Solution Overview The multisite solution described in this document equally applies across financial, manufacturing, consumer or information based industries interested in constructing and deploying efficient and productive data centers. Data centers house the applications and information critical to the business, whatever that may be. Today, enterprises recognize that a data center is more than racks of compute power, but an asset with the potential to provide a competitive edge. As a result, industries are reevaluating their data center deployments with an interest to consolidate or expand where necessary to address the following New infrastructure including network and compute resources 6. Regulatory compliance typically resulting in expanded security and storage infrastructure Facility space, power, and cooling to support new infrastructure New application environments and performance expectations Disaster recovery The multisite solution described in this document focuses on the expectations of the application of four fundamental design goals Application high availability Application scalability Data and application security Application performance This document highlights network based technologies used within and between data centers to achieve these objectives. Solution Topology Figure 1 depicts the Microsoft Exchange Server 2. Data Center 1 and Data Center 2 are deployed leveraging Ciscos infrastructure design best practices. Note that each site provides local redundancy, scalability, and security for the applications it hosts. A multisite solution should simply extend the functionality of a single site and should not compromise the integrity of either. At each site in Figure 1, the hub and mailbox servers leverage the Layer 2 and 3 services of a well designed access and aggregation layer. The access and aggregation layers consist of the Cisco Catalyst 6. Sup. 72. 0s. In the aggregation layer of each site, a pair of Cisco 7. NPE G2s provide an L2. TPv. 3 tunnel. This tunnel establishes Layer 2 adjacency between sites on a per VLAN basis, efficiently meeting the requirements of our Exchange Server 2. The L2. TPv. 3 tunnel traverses the core layer, which is a high speed Layer 3 fabric consisting of the Cisco Catalyst 6. Sup. 72. 0s. The red lines indicate the use of 1. Gigabit. Ethernet throughout the access, aggregation, and core layers. Figure 1 defines two points of access into the data center for remote users via the WAN or the Internet. The remote branch users in the WAN benefit from the transparent and symmetric application optimization services of the Cisco Wide Area Application Services WAAS. Cisco Wide Area Application Engines WAEs are located at each site and at the remote branch. Users originating from the Internet connect via a DMZ local to each data center site. The DMZ consists of Cisco Catalyst 6. Sup. 72. 0s housing the Cisco Application Control Engine ACE service module, which provides application and security services. The Exchange edge and CAS roles reside in this location. In addition, the Internet edge houses a cluster of Cisco ACE Global Site Selectors GSS, which monitor the state of each data centers Exchange application environment and uses this knowledge to provide intelligent selection between sites. This document discusses each of the areas defined in Figure 1 to provide a better understanding of the application and the network deployed to support it. Figure 1 Solution Topology Cisco Technology Overview This section provides an overview of the main Cisco products and technologies used in this design. The following products are addressed Cisco Application Control Engine ACE Cisco ACE Global Site Selector ACE GSS Cisco Wide Area Application Engine WAE The Cisco ACE provides a highly available and scalable data center solution from which the Microsoft Exchange Server 2. Windows Live Mail Notifier. Currently, the Cisco ACE is available as an appliance or integrated service module in the Cisco Catalyst 6.
