Executive Summary
QLogic has carried out a comparative I/O performance and scalability study of commercially available 4Gb Fibre Channel (FC) HBAs. Microsoft Exchange was chosen as an application of choice for the benchmarking exercise because e-mail is the most business critical application today. According to The Radicati Group, the average e-mail data volume per user increased by 53% between 2003 and 2004. The growth of e-mail in business use has been disruptive with corporate e-mail usage expected to jump 38.49% from 439 million mailboxes in 2005 to 608 million mailboxes in 2009. Similarly, consumer e-mail usage is expected to jump approximately 70% from 926 million mailboxes in 2005 to 1576 million mailboxes in 2009. Microsoft Exchange has the dominant market share with 32% of the Installed base in 2005 which is expected to climb to 37% of the Installed base in 2009.
