HP released a new whitepaper for companies who are planning to deploy medium and large Exchange environments on HP infrastructure. All the information is based on the Microsoft Exchange Solution Reviewed Program (ESRP) – Storage program.

This solution implements the Database Availability Group (DAG) mailbox resiliency feature found in Microsoft Exchange Server 2013 (Exchange). This feature is the base component of the high availability and site resilience framework built into Exchange. A DAG is a group of up to 16 mailbox servers that hosts a set of databases and provides database-level recovery from failures that affect individual servers or databases.

This solution brief describes a tested configuration for deploying Microsoft Exchange Server 2013 (Exchange) in a 5,000- user, mailbox-resilient environment. The performance results and best practices outlined in this document provide tested guidelines for configuring Exchange with HP D6000 disk enclosure, HP ProLiant BL460c Gen8 Server Blades, and HP Smart Array P721m controllers in a direct-attached storage (DAS) solution.


This solution uses a single DAG to support 5,000 mailboxes, each with a 5 GB mailbox capacity and a work profile of 200 messages sent and received for each user, each day. Four copies of each database provide mailbox resiliency, with two copies located at the primary site and two copies located at the disaster recovery site.
