EKEY01: Next Generation Messaging
Tony Redmond
Microsoft Exchange 2007 is very different to the generations of Exchange that have gone before and forces administrators to consider new ways of deploying the Exchange ecosystem onto a Windows 64-bit platform. All we can guarantee about technology is that change will continue to occur or even accelerate as new hardware and software technologies influence the design decisions that groups like the Exchange engineering team make as they work on new versions of Exchange to appear in the 2010-2015 timeframe. This session discusses some of the technology directions that may influence the way that Exchange evolves, including virtualization, mobility, information lifecycle management, unified communications, automation, and software as a service.

This session will show you some common pitfalls and problems and give you the knowledge to successfully navigate them.

EXC22: Exchange Storage Sizing and Hardware Exposed
Jim McBee
Have you accurately estimated the amount of storage that you require in the past? Do get a sharp pain in your chest when you think about I/O capacity and IOPS? Do you blindly nod when your SAN engineer tells you what he is going to provide you? Do you know a megacycle from a megaflop? When did sizing an Exchange server get so darned complicated? This session is designed to help demystify the process of picking the right amount of RAM, CPU capacity, and storage capacity. The session is targeted towards Exchange administrators and system engineers that must plan, deploy, and support Exchange servers with 100 to 20,000 mailboxes and that need to know the right answers to the “storage people’s” questions. We will look at not only disk capacity planning but also ensuring that the disk subsystem is sized appropriately for the amount of disk I/O that the user community will require. This topic will include using basic performance monitoring tools to examine your existing capacity requirements.

EXC18: Getting Run Over by Exchange 2007
