ASB Bank improves the resiliency of their email system to increase uptime with Microsoft Exchange Server 2010.

Bank Restores E-Mail Service in Seconds, Builds a Base for Communication and Collaboration

asbASB in New Zealand wanted to improve the resiliency of the e-mail system it relied on for business processes. It could take 30 minutes or more to restore service after an outage, and routine maintenance had to be performed when users were offline. The bank also wanted to explore capabilities such as archiving and unified messaging. It decided to meet its goals by implementing Microsoft Exchange Server 2010. To improve uptime, ASB installed a Database Availability Group to automate recovery and can now restore service within 30 seconds. The bank expects to use low-cost SATA storage and cut support overtime costs. It also plans to simplify compliance and improve the user experience with built-in archiving and compliance capabilities.
