Exchange 2010 indicates an I/O reduction of around 90% when compared Exchange 2003, and 50% against Exchange 2007, while this does not necessarily translate into less disks (due to increased mail volumes, larger mailboxes, and wider usage across Enterprise employee’s as a common part of HR policies to ensure all employee’s have access to email), it does provide the opportunity to deploy a different TYPE of disk.
A report from EMC focusing primarily on their Clariion SAN technology summarises the power consumption of different sized disks with differing performance stats. The following diagram is extracted from the report and demonstrates the significant energy saving of utilising higher capacity drives that can be used for Exchange 2010 as I/O performance requirements are reduced:
increasing email volumes.
Despite the widespread adoption of email by corporate enterprises over a decade ago, the growth of emails sent and received per person per day is still rising sharply. The graph below illustrates how daily email quantities are predicted to continue to grow by a further 30% in the next two 2 years.
While end-users are feeling the Email growth pain, the impact to Enterprise IT Function is compounded by both volume AND complexity. Email is no longer just the sending and receiving of messages, instead Email today relies on a complex Eco-system of messaging and related services that address wide variety of Enterprise requirements to ensure compliance, policy enforcement, security, disaster recovery / business continuity, and long term data retention.
The cost of email isn’t simply accounted for by the sending and receiving of emails, instead it is comprised of a complex email eco-system that typically contains an intertwined web of services for security, archiving, compliance, continuity services, and a plethora of access methods utilised by increasingly mobile workforces, operating in many time zones often outside of core IT hours and local office hours.
Typical Enterprise-scale organisations have multiple messaging systems due to mergers and acquisitions. This presents the opportunity to consolidate, centralise and standardise the messaging platform on to the latest software version to minimise support costs, take advantage of new features and functionality, and integrate with desktop client software refresh programmes.

Memories swiftly returned of spending hours typing in programs from Input magazine back in the '80s, which all started with the simplest of programs to display 'Hello World' on the screen.
