This IBM® Redpaper™ is one in a series that describes System z®-qualified optical Wavelength Division Multiplexing (WDM) vendor products for Geographically Dispersed Parallel Sysplex™ (GDPS®) solutions with Server Time Protocol (STP). The products that we describe in this series are also the IBM-supported solutions for non-GDPS applications. Non-GDPS applications include the protocols that are needed for cross-site connectivity of a multisite Parallel Sysplex® or one of the remote copy technologies that we describe in this paper. GDPS qualification testing is carried out at the IBM Vendor Solutions Connectivity (VSC) Lab in Poughkeepsie, NY, USA.

IBM and Ciena Communications Inc. successfully completed qualification testing of the Ciena CN 4200 platform. In this Redpaper, we describe the applicable environments, protocols, and topologies that are qualified and supported by System z for connecting to the Ciena CN 4200 platform hardware and software at release level 6.0.1 and 6.0.2. This paper supersedes all previous versions.
