Dell Compellent Storage Center (SC8000) 2,500 Mailbox Exchange 2010 Resiliency Storage Solution

The Mailbox Resiliency features of Microsoft Exchange 2010 have greatly enhanced the availability of Exchange 2010, while also improving I/O performance. The solution presented here is a Mailbox Resiliency solution utilizing 1 Database Availability Group (DAG) and 2 copies of every database. The tested environment simulates all users in this DAG running on a single Storage Center. The number of users simulated was 2,500 across 2 servers, with 1,250 users per server. The mailbox size was 2GB per user. Each server has 2 databases, with one copy local and the second copy replicated to the second server. This provides redundancy through hardware and software.

The testing shows the scalability and performance of the Dell Compellent Storage Center (SC8000). This is a redundant controller pair, with redundant front-end and back-end connections. The front-end connections were fiber-channel based, over redundant fabrics, with 2 ports per server, and 4 ports per controller.
