Ciena Corporation, a global provider of network solutions, today announced that Zhejiang Unicom, a subsidiary of China Unicom, has selected Ciena's CN 2600 Multiservice Edge Aggregator (formerly known as ONLINE Edge) to support storage area network (SAN) extension for its data center disaster recovery and restoration plans.

Utilizing Ciena's CN 2600 multiservice platform, which delivers service transparency through coarse wavelength division multiplexing (CWDM) technology, Zhejiang Unicom is implementing a distance backup solution to support remote business continuity measures and dramatically improve recovery performance in the event of unplanned downtime. Ciena's storage extension technology plays an important role in this effort by linking Zhejiang Unicom's primary data center to a back-up data center, located more than 80 kilometers away, within the company's SAN architecture.
