Nortel Networks and EMC Corp. have released a new joint services offering to help enterprises utilize optical metropolitan area networks and wide area networks for remote mirroring of their data.

The companies said the new offering can help customers determine the optimal storage and connectivity requirements to meet their recovery objectives. It combines EMC’s networked storage systems and remote replication software with Nortel’s dense wavelength division multiplexing technology.

This combination, the companies say, gives enterprises the flexibility to match the right levels of protection and functionality for their various information tiers. In addition, by using EMC’s replication software, customers can improve recovery times.
