Children's Hospital split its storage clusters, with half at the disaster recovery site and the rest at the main data center downtown. The key to making this work is a very fast, responsive network connection using Ciena's Adaptive WAN products running over a private 2 Gb/s fiber physical layer. The network uses EMC's Symmetrix Remote Data Facility and MirrorView to support synchronous backup of all data to the disaster recovery site, resulting in less than five minutes to fail-over, validate and move on.
