Converged infrastructure for enterprise exchange environment

Email messaging has always been a part of enterprise IT environment but today, Enterprise messaging is viewed as a business-critical application that needs a highly reliable and scalable infrastructure to meet the information growth and data availability requirements of an enterprise. It is therefore, very important to create a scalable, capacity and performance optimized infrastructure to host the enterprise messaging solution. Converged Infrastructure Solution aims at addressing the infrastructure requirements of business-critical applications by providing a pre-validated application-oriented integrated suite of compute, network and storage solutions that can reduce infrastructure complexity provide seamless scalability and resiliency with minimized business disruption. This paper outlines the key requirements of an enterprise Exchange environment and discusses the converged infrastructure sizing considerations for Microsoft Exchange 2010 environment. The paper also provides reference architectures for hosting small (3000 users), medium (10000 users) and large (20000 users) Exchange configurations on converged infrastructure solutions.
