The IBM Redbooks team recently published IBM Redpapers related to IBM System z® qualified Dense Wavelength Division Multiplexing (DWDM) vendor products for IBM Geographically Dispersed Parallel Sysplex™ (IBM GDPS®) solutions with Server Time Protocol (STP). The papers highlight the System z Qualified test process and technical details of the DWDM vendor platforms that were tested.
GDPS is an enterprise-wide continuous availability (CA) and disaster recovery (DR) automation solution that can manage recovery from planned and unplanned outages across distributed servers and System z servers. GDPS can be configured in either a single site or in a multisite configuration. It is designed to manage remote copy configuration between storage subsystems, automate Parallel Sysplex operational tasks, and affect failure recovery.
To obtain this qualification, DWDM vendors acquire licensed IBM patents, intellectual property, and know-how that are related to the GDPS architecture. This licensing provides vendors access to the proprietary IBM protocols and applications that are used in a GDPS environment.
Below depicts the environment that is used for System z qualified testing.
The team members that wrote the papers are subject matter experts from the IBM Vendor Solutions Connectivity (VSC) Lab in Poughkeepsie, New York: Pasquale Catalano and Andrew Crimmins, and Bill White (IBM Redbooks team leader).
