Microsoft Exchange is a mission-critical infrastructure staple in organizations of all sizes. As an application which demands high levels of the "-abilities" (availability, reliability, scalability, etc.) and stringent resource demands, the sizing process is critical to ensuring a healthy production environment. Sizing Exchange 2010, which introduces a new replication and resiliency model (DAGs), a personal archive and enterprise archiving capabilities, as well as dramatic I/O reductions, radically changes the approach to storage design. Enhancements and new functionality hosted in the client access server, support for role consolidation on a single server and optimization for Software + Services models bring similar challenges when designing servers. This session addresses sizing and performance tuning methodology, and a time-tested approach for applying this methodology to your environment. The session covers key enabling hardware advancements, such as x64 architectures, multi-core processors, SATA, SAS and SSD disk technology, and how these technologies will play a key role moving forward with Exchange 2010. Finally, the session provides rules of thumb, for sizing the key server roles and technologies associated with typical deployments of Exchange 2010.
