What’s new in Exchange Server 2010?1. 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

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
• 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
ADC for highest availability
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

What’s new in Exchange Server 2010?
1. Elevation of Client Access Server (CAS) role• All client connections, regardless of protocol, are with
CAS servers2. Microsoft recommends hardware load balancing over
NLB• Multi-role Exchange server installations• Installations with Microsoft clustering services

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

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
