Heightened security concerns and regulatory mandates are forcing large companies to reevaluate their business-continuance and disaster-recovery policies and to seek efficient, fault-tolerant alternatives for transporting their storage. Through its Multiservice over SONET/SDH (MSOS) strategy, Cisco Systems helps enterprises to build reliable storage area network (SAN) Extension models to efficiently interconnect their SAN islands, and achieve their fault-tolerance targets.
With Cisco MSOS, service providers can now offer SAN Extension services, in addition to the traditional time-division multiplexing, OC-n, and Ethernet service, all without extensive equipment upgrades or infrastructure impact. Furthermore, those carriers currently offering managed storage services can migrate to a more-profitable services model by taking advantage of their existing SONET/SDH infrastructure investments to deliver SAN Extension services. The Cisco ONS 15454 SL-Series Multiservice Provisioning Platform Line Card for the Cisco ONS 15454 SONET Multiservice Provisioning Platform (MSPP) offers service providers and enterprises the opportunity to deliver Fibre Channel and IBM Fiber Connection (FICON) over SONET/SDH infrastructures. Line-rate support for 1-Gbps and 2-Gbps Fibre Channel interfaces, flexible interface options, and interoperability with the Cisco MDS Family, allow the ONS 15454 SL-Series to deliver complete, SAN Extension solutions without restrictions.
