Microsoft Exchange Server 2016 is a leading enterprise messaging system that delivers email, calendar, voice mail and contacts to users on a variety of devices through the Outlook client. Exchange Server 2016 provides reliable, scalable, enterprise-class email with compliance and e-discovery features integrated with Microsoft SharePoint and Skype for Business. Exchange Server 2016 supports people and organizations as their work habits evolve from a communication focus to a collaboration focus. The database design in Exchange 2016 reduces the storage I/O requirements, thereby optimizing Exchange for cost-effective, low-speed storage. Exchange deployment must be appropriately sized to meet not only specific message profile requirements, but also growth and high availability requirements.

This Design Guide describes the design principles and solution components for Dell EMC Ready Bundle for Microsoft Exchange suited for very large scale deployment. The solution uses DSS 7500 sleds on a DSS 7000 chassis as a building block, as it can support large volumes of data. The design is explained with a sample implementation of 100,000 mailboxes. Customers needing larger implementations can also use the building blocks to scale out as per their business needs.
