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 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 can include GDPS and non-GDPS applications. GDPS qualification testing is conducted at the IBM Vendor Solutions Connectivity (VSC) Lab in Poughkeepsie, NY.
