Regulatory compliance, heightened awareness of the risks associated with inadequate disaster recovery plans, and the quest for more efficient utilization of storage assets are factors driving the interconnection of storage area networks (SANs).

Nortel Networks has created solutions, which focus the power and proven capabilities of SONET and SDH on the current and pressing business problem of extending mainframe and open system traffic across WAN distances.
