Using Flash Cache for Exchange 2010

Free registration required

Executive Summary

Microsoft Exchange 2010 includes several improvements to support larger mailboxes at lower cost. For example, a typical Exchange 2010 mailbox size is expected to be greater than 1GB, while generating ~0.10 Input/output Operations Per Second (IOPS), compared to ~0.30 to 0.40 IOPS for Exchange 2007. This reduced level of I/O operations presents the option to use low-cost SATA disks with Exchange 2010. NetApp Flash Cache (formerly PAM II) reduces costs for storage, power, and rack space by optimizing the performance of random read-intensive workloads such as file services, messaging, virtual infrastructure, and OLTP databases.
