HP released recently this great solution brief which provides an HP 3PAR StoreServ 7400 storage solution for Microsoft Exchange Server 2010 (Exchange), based on the Microsoft Exchange Solution Review Program (ESRP) – Storage Program.

This brief describes a tested configuration for deploying Exchange in a 60,000 user mailbox resilient environment. The performance results and best practices outlined in this document provide tested guidelines for configuring Exchange with the HP 3PAR StoreServ 7400 and HP ProLiant BL460c Gen8 BladeSystem Servers in a SAN solution.

This solution used two DAGs to support 60,000 mailboxes, each with a 2 GB mailbox capacity and a 0.14 IOPS workload per user. To provide mailbox resiliency, there are three copies of each database; two copies located in the primary site and one copy located in the disaster recovery site. The primary site hosts all 60,000 mailboxes during normal operations. The performance results are from the testing of the disaster recovery site.
