There is an increase in the number of companies and organizations requiring 24 x 365 days of IT uptime. In fact, research indicates that 36% of enterprises indicate they will incur significant revenue loss or other adverse business impact if they have even an hour or less of downtime on their

mission-critical applications. Almost 15% indicate they cannot tolerate any downtime. More and more organizations of all sizes now require applications to be running and data to be always available. The needs of these organizations go far beyond simply recovery, requiring an environment that maintains business continuity during and immediately after a disaster. To make it more interesting, the number and types of applications that require this level of protection is very diverse.
