2. What’s new in Exchange Server 2010? • Elevation of Client Access Server (CAS) role • All client connections, regardless of protocol, are with CAS servers • CAS servers rely on ADC for high-availability CAS is critical

3. Exchange 2010 Architecture Enterprise Network Phone system (PBX or VoIP) Hub Transport Routing and policy Edge Transport Routing and AV/AS External SMTPservers Unified Messaging Voice mail and voice access Mailbox Storage of mailbox items Mobile phone Client Access Client connectivity Web services Web browser Outlook (remote user) Line of business application Outlook (local user)

4. What’s new in Exchange Server 2010? ADC for highest availability • Elevation of Client Access Server (CAS) role • All client connections, regardless of protocol, are with CAS servers • CAS servers rely on ADC for high-availability CAS is critical • Microsoft recommends hardware load balancing for every Exchange 2010 deployment • ADC recommended over NLB • Includes multi-role Exchange server installations • Includes installations with Microsoft clustering services

5. The F5 Solution for Exchange Server 2010 • Prevent these pains • Dropped sessions  re-authentication, reconnection • Failed network connections  retries, delay • Slow response  trapped users • These capabilities • Health monitoring and intelligent load-balancing • Client persistence • Server off-load • Availability of servers, arrays and sites

6. What’s new in Exchange Server 2010? HWLB for highest availability All clients need BIG-IP • Elevation of Client Access Server (CAS) role • All client connections, regardless of protocol, are with CAS servers • Microsoft recommends hardware load balancing over NLB • Multi-role Exchange server installations • Installations with Microsoft clustering services Technical white paper on the MS internal Exchange design: http://technet.microsoft.com/en-us/library/ff829232.aspx

7. The F5 Solution for Exchange Server 2010 • High-availability and superior user response • Site resilience • Reduced time and cost to replicate mail store • SPAM filtering and web client security

9. Configuration - we have a template for that

10. Availability • Health monitoring • Port/protocol requests • Real-time in memory connection tables • Intelligent load-balancing • BIG-IP always knows the most available server • Least connection method • See application template • Cross site availability • Site level health • Prioritized decision tree

11. Persistence • Also known as affinity, or sticky sessions, persistence can help enhance a user’s application experience • Different types of persistence: • Source IP • Cookie • SSL ID • Each Exchange client connection type has a recommended persistence method

12. Configuring persistence profiles in BIG-IP LocalTrafficProfilesPersistenceCreate Source IP and SSL ID Cookie

13. Performance - SSL termination • Reduce cost and overhead of managing certificates by moving them to BIG-IP • BIG-IP is designed with dedicated chipset for encryption/decryption calculations • Increase Exchange server CPU utilization and network connections per second

14. Security • Bi-directional proxy • Secure remote access • Pre-authentication • Application layer security for web clients • SPAM filtering

15. Multi-datacenter considerations • Multiple datacenters provides additional options for redundancy and load-balancing • Load-balancing and Failover across locations • DNS management • Secure, accelerated application data synchronization • Seamless integration with systems management tools • Key enabling functionality • BIG-IP LTM – GTM communication • iSessions • iControl • F5 PRO-Enabled Management Pack

16. Summary • Highest availability through intelligent, hardware-based load-balancing of client connections to CAS servers • Dramatically increased server processing power through off-loading of SSL, caching, compression and client connection isolation. • F5 enables cross-site availability and resilience • Pre-authenticate users in the perimeter network • F5 devices can be controlled using PowerShell and Management Packs
