This IBM® Redpaper™ is one in a series that describes System z® qualified optical Wavelength Division Multiplexing (WDM) vendor products for 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, New York (NY), United States of America (USA).

IBM and Cisco Systems Inc. successfully completed qualification testing of the Cisco ONS 15454 MSTP platform. In this Redpaper publication, we describe the applicable environments, protocols, and topologies that are qualified and supported by System z for connecting to the Cisco ONS 15454 MSTP platform hardware and software at release level 8.5 and 9.0.This paper supersedes all previous versions.
