This document describes a mid-range Exchange 2010 storage solution for 16,000 mailboxes on the IBM System Storage DS3512 dual-controller storage system. The solution utilizes two DS3512 storage systems, with each system including a dual-controller DS3512 and seven EXP3512 expansion units for a total of 96, 2-TB NL-SAS disk drives. The two separate DS3512 storage subsystems and associated disks are required to provide DAG redundancy and failover capability. This system could scale out by adding additional controller subsystems to support larger environments. IBM has recently added 3-TB NL-SAS drives for use in the DS3512 storage system.
