Scalable Hosted Exchange Architecture

Scalable Hosted Exchange Architecture

Through the introduction of new server roles, Microsoft Exchange Server 2007 setup and deployment has been re-engineered to improve the administrative experience. Exchange Server 2007 provides five distinct server roles that align with the way messaging systems are typically deployed and distributed.

A server role is a unit that logically groups the features and components that are required to perform a specific function in the messaging environment. Each server role includes features that support its function together with related configuration and security settings and a list of predefined tasks for managing and configuring those features.

Tiered Support for Specific Customers

The reference architecture is designed to support a tiered approach to implementation of services. The architecture is designed to support those hosters entering the market with plans to grow their services offers on pace with the growth of the business.

The architecture targets three design points:

• Entry Tier - MAPI subscriber base from 1 - 5000
• Middle Tier - MAPI subscriber base from 5000 - 20,000
• Upper Tier - MAPI subscriber base from 20,000 - 100,000

The solution design defines the number of servers required for each design point with a set of formulas as part of the solution to provide the tools service providers can use to grow their service from one design point to the next.
