The town of Gilbert Arizona has been a client of N2 Network Solutions for years. In 2009 Gilbert needed an Exchange 2007 solution. N2 discovered, designed, and implemented a turn key Exchange solution. This solution included continuous cluster replication or CCR for redundancy in the mail environment. This gives Gilbert the ability to perform routine maintenance on one server without disrupting the end users. Once this is complete the cluster can be switched to the secondary server so maintenance can be performed on the primary.
