Exchange Server 2010 Design and Architecture at Microsoft

The most important benefits that Microsoft IT achieved with the production rollout of Exchange Server 2010 included:

·         A reduction in input/output per second (IOPS) of 70 percent since Microsoft Exchange Server 2007. The database optimizations of Exchange 2010 provide better performance and reduced storage costs. This results in a savings of more than 50 percent in the total cost of ownership (TCO) of storage.

·         An increased Mailbox size of 5 GB for all mailboxes in the organization.

·         Increased mailbox migration velocity over Exchange Server 2007, which enabled Microsoft IT to migrate the entire company much more quickly.

·         Elimination of backups, which saves millions of dollars per year.
