Founded in 1970 and owned by approximately 60,000 shareholders, Dombivli Nagari Sahakari Bank Ltd. (DNS Bank) is a cooperative bank in Dombivli, India, a suburb of Mumbai.

Business need
The bank wanted a cost-effective and proven disaster-recovery solution to keep its production database online, with negligible downtime during server or database outages. With a limited support staff of three, the bank also needed an easy-to-manage solution. 

An integrated, optimized hardware, software and storage solution minimized downtime from planned activities and unplanned events, such as power outages. A two-node cluster automates switching of users, applications and data from one system to another in case of hardware or software failure. The DB2 HADR feature maintains availability of a secondary node in continuous replication with the primary node.

- 99.99 percent reduction in downtime from days to seconds - 30 to 35 percent savings from the cost of other vendors’ disaster recovery solutions - 25 to 30 percent of Fibre Channel disk space reclaimed with Deep Compression
