Every day, companies around the world rely on the features of Microsoft Exchange for their business-critical applications like email, calendaring, contacts, mobile support, web-based information accessing and data storage support. While we’ve discussed the importance of maintaining Microsoft Exchange high availability and steps to simpler Exchange HA, we thought this would be a good opportunity to share a case study from one of our customers.

Connecting Employees, Vendors and Customers Without Interruption

A large U.S. furniture retailer was becoming increasingly dependent on Microsoft Exchange 2003 for internal communication and collaboration, and for communication with both vendors and customers. Since the retailers primary revenue-generating activities relied on e-mail, downtime would have resulted in serious consequences. As a result, Exchange protection became a requirement and top priority for senior leaders.

everRun –An Alternative to Clustering

The IT staff had previous experience with traditional clustering and was looking for an easier, more robust solution. They selected everRun and implemented a solution using a pair of IBM servers with local boot disks and a fibre channel SAN for the datastore. Currently, the system supports close to 1200 users.

No Exchange Failures = Increased Competitive Advantage

In over a year of operation, they have not experienced a single unplanned disruption of their Exchange system. In turn, this has allowed them to keep their revenue-generating activities operating at full speed. As a result, they are currently looking at adding the everRun SplitSite option to allow geographical separation of their systems for additional protection.

Do you have a story when protecting Exchange would have been a better option than what resulted? How did it affect you or your company?
