This paper provides a highly resilient Microsoft® Exchange 2013 storage solution for up to 2,500 mailboxes using the validated design described in this study. The solution includes a single Data Availability Group (DAG), and three copies of each database spanning two sites. Dell PowerEdge R730xd servers are used as the mailbox servers for the Exchange mailbox databases. The tested environment simulates up to 2,500 users with a mailbox profile of 5 GB and 150 messages per day, or 0.121 IOPS for every user, including 20 percent headroom.

This is the new, most suitable building block for any mid-size or large business. It delivers enormous storage capacity and IOPS performance in a dense 2U form-factor, enabling larger and more efficient databases and mail servers.
