Validating Microsoft Exchange 2010 on Cisco and NetApp FlexPod with the F5 BIG-IP System

Updated October 05, 2012

Introduction

As organizations begin virtualizing Tier I, mission-critical applications, they face the significant challenge of pre-validating a data center platform to support their scale and performance requirements. FlexPod, a validated data center design built on NetApp and Cisco technologies, fills this crucial gap by enabling certified NetApp and Cisco partners to design, build, and provide a pre-validated platform for their enterprise customers seeking to deploy Tier I applications in a virtualized environment.

As FlexPod data center solutions enable customers to efficiently deploy virtualized applications by providing a pre-validated design from the storage, compute, and Layer 2 networking perspective, the F5® BIG-IP® system provides the application delivery services, availability, and security necessary to fully deploy an application. When they deploy the BIG-IP system in concert with FlexPod validated data center designs, enterprises will realize a dramatically improved return on their investment by maintaining application availability, simplifying business continuity and application security, and improving the end user experience.

As enterprises around the world transition to increasingly virtualized environments, many must also upgrade their Microsoft Exchange deployments. Deploying Exchange 2010 in a virtualized environment comes with challenges, but FlexPod pre-validated data center designs, together with F5 application delivery technologies, address many of them in a complete application solution. To explore this, F5 built out a joint FlexPod and Exchange 2010 solution in partnership with Scalar Decisions and Avnet Canada.

How FlexPod and F5 Technologies Enable a Scalable and Secure Exchange 2010 Deployment

Performance and Scale of Exchange 2010

Moving to a virtualized Exchange 2010 environment from an Exchange 2007 environment requires a substantial degree of infrastructure planning. The Exchange 2010 Infrastructure and Design Guide strongly recommends that organizations use hardware load balancers to direct access to Client Access Servers. FlexPod validated data center designs provide a comprehensive platform for a virtualized Exchange 2010 deployment; adding F5 BIG-IP Application Delivery Controllers (ADCs) to the solution ensures that organizations experience better application availability and performance. BIG-IP features such as SSL offload, connection pooling, and adaptive compression can improve end user access to Exchange 2010 mailboxes, overall end user experience, and overall satisfaction with their Exchange 2010 deployment.

Advanced Data Protection

NetApp snapshot and replication technologies in FlexPod data center platforms provide users with a comprehensive, disk-based data protection suite. NetApp SnapManager for Microsoft Exchange Server ensures not only data protection, but that the application state is maintained so data and application recovery can occur when necessary. This becomes even more critical in a virtualized deployment of multiple applications.

F5 ADC acceleration technologies are instrumental in a cost-effective disaster recovery and business continuity strategy. F5 BIG-IP® WAN Optimization Manager™ (WOM) ensures rapid and reliable mailbox replication so organizations can meet their SLAs and provide superior replication performance. Additionally, BIG-IP WOM has been validated to accelerate NetApp SnapMirror replication operations to address customers who have WAN links with high latency, packet loss, or limited WAN capacity budgets.

Maintain Availability of Exchange 2010

With the advanced monitoring capabilities of BIG-IP® Local Traffic Manager™ (LTM), administrators know they can maintain application availability whether the environment is virtualized or physical. F5 advanced monitoring capabilities ensure that users can scale their Exchange virtualized infrastructure to support thousands of users simultaneously.

Rapidly Deploy a Fully Virtualized Infrastructure

Enterprises seeking to realize the substantial benefits of full virtualization can dramatically shorten the planning and deployment phase of their initiatives. FlexPod pre-validated data center platforms are pre-configured to support the scale and performance characteristics of any enterprise. Certified F5, Cisco, and NetApp technology partners, such as Scalar Decisions, ensure that a combined F5 and FlexPod solution is pre-validated to suit a given environment.

F5 iApps™ is a powerful set of features in the BIG-IP system that enables organizations to rapidly deploy complex application delivery services for both upgrades and new deployments of Exchange 2010. With iApps, organizations can effectively deploy crucial ADC technologies into a FlexPod virtualized environment.

Simplified, Secure Remote Access

Organizations’ increasingly mobile and distributed workforces present the significant challenge of providing simplified access to Exchange without compromising security. F5 BIG-IP® Access Policy Manager® (APM) provides secure single sign-on (SSO) authentication to Microsoft Outlook or Outlook Web Access (OWA) whether the user is on a traditional laptop, smart phone, or other mobile device.

Review of Environment Setup and Deployment

To demonstrate the simple integration between F5 and FlexPod pre-validated data center designs, F5 deployed Exchange 2010 on its VIPRION® chassis with FlexPod providing the storage, compute, and layer 2 networking. This test scenario revealed several benefits of adding F5 to FlexPod architectures for secure access and traffic management to an Exchange 2010 environment. F5 validated this solution in partnership with Scalar Decisions, a leading F5 and NetApp technology partner, in an Avnet Labs environment in Mississauga, Ontario.

F5 provisioned a VIPRION 2400 device, running version 11.2 of the BIG-IP system, to provide application traffic management for an Exchange 2010 deployment, with the aim of optimally configuring the VIPRION appliance to support the Exchange 2010 deployment on a pre-validated FlexPod data center solution. The solution included both a Nexus switch configuration and the F5 BIG-IP LTM networking setup and configuration for F5 vCMP® (Virtual Clustered Multiprocessing), a virtualization solution designed to scale ADC instances across the BIG-IP platform. It also used F5 iApps for Exchange 2010 to streamline the BIG-IP deployment, which in turn supported a Microsoft Exchange 2010 deployment on a FlexPod platform. For more information about F5 iApps, a powerful solution for configuring, managing, and deploying application delivery services across multiple BIG-IP appliances both on- and off-premises, read the F5 white paper, F5 iApps: Moving Application Delivery Beyond the Network.
