This document provides information on Dell Compellent's storage solution for Microsoft Exchange Server, based the Microsoft Exchange Solution Reviewed Program (ESRP) – Storage program.  

The solution presented here is an Exchange 2013 Mailbox Resiliency solution utilizing 2 Database Availability Group (DAGs) and 2 copies of every database. The tested environment simulates all users in this DAG running on a single Storage Center, or half of the solution. The number of users simulated was 50,000 across 10 servers, with 5,000 users per server. The mailbox size was 2GB per user. Each server has 5 databases, with one copy local and the second copy replicated to the second server. This provides redundancy through hardware and software.
