This IBM® Redpaper™ publication is one in a series that describes IBM z Systems qualified Dense Wavelength Division Multiplexing (DWDM) vendor products for IBM Geographically Dispersed Parallel Sysplex™ (IBM GDPS®) solutions with Server Time Protocol (STP). The protocols that are described in this paper are used for IBM supported solutions that require cross-site connectivity of a multisite Parallel Sysplex or remote copy technologies, which may include GDPS and non-GDPS applications. GDPS qualification testing is conducted at the IBM Vendor Solutions Connectivity (VSC) Lab in Poughkeepsie, NY.

IBM and Huawei successfully completed qualification testing of the Optix OSN 8800 and Optix OSN 6800 platforms.
