IBM System z Software Pricing

Hardware Criteria to be considered 'actively coupled':

You must have two or more eligible mainframes that are physically attached via coupling links to a common Coupling Facility. In addition, time synchronization must be provided using either timer links to a common Sysplex Timer or coupling links transporting Server Time Protocol ("STP") timing information in an STP Coordinated Timing Network ("CTN").

Note: If a Coupling Facility is divided into multiple logical partitions (LPARs), all mainframes must be attached to the same Coupling Facility LPAR.

Eligible Mainframes

Eligible Mainframes are listed in the appropriate manufacturer's page on the Mainframe Exhibits section of the System z Software Contracts web site with one of the following notations:

• "PSLC=YES" in the PSLC column
• "PSLC=Aggr. Only" in the PSLC column
• "WLC" or “(A)” in the WLC column

Coupling Facility list

Qualifying Coupling Facilities may be one of the following:

Standalone Coupling Facilities on IBM or other manufacturers' mainframes, as listed in the Machines column of the Standalone Coupling Facilities page (PDF, 14.8KB) of the hardware section of the System z Exhibits website. Amdahl, Comparex, Fujitsu, HDS, Hitachi, and Olivetti machines must have the external coupling link features installed and operational.

Mainframes in which LPARs may be configured to act as Coupling Facilities as listed in the appropriate manufacturer's page on the Mainframe Exhibits section of the System z Software Contracts web site. Mainframes which qualify are designated by the letters "CF" in the Coupling Facility column.

In the case where an LPAR is configured as a Coupling Facility, the following specific conditions apply to the mainframes where the Coupling Facility LPAR exists:

For IBM:

• A machine with an Internal Coupling Facility (ICF), or
• 2817, 2818, 2097, 2098, 2094, 2096, 2084, 2086, 2064, 2066, or 9672 with one or more central electronic complexes (CECs) or logical partitions running the Coupling Facility control code, or
• A 9021 with engineering change 228270 or later installed, and a logical partition running the Coupling Facility control code.

For Amdahl:
A machine with the following installed and operational:

• Amdahl Parallel Sysplex Migration Feature (PSMF), or
• Amdahl Coupling Control Code and external coupling link features, or
• For Millennium machines, Amdahl Internal Coupling Server feature and external coupling link features.

For Comparex:

• A C2000 or M3000 machine, or
• A M2000 machine with the Voyager Coupling Code and external coupling link features installed and operational.

For Fujitsu:
A machine with the following installed and operational:

• Fujitsu Parallel Sysplex Migration Feature (PSMF), or
• Amdahl Coupling Control Code and external coupling link features, or
• for Millennium Global Server machines, Fujitsu Internal Coupling Server feature and external coupling link features.

For HDS and Olivetti:

• A Pilot or Trinium machine, or
• A Skyline machine with the Voyager Coupling Code and external coupling link features installed and operational.

For Hitachi:

• A GP7560 or GP7600 machine, or
• A GP7580 machine with the Voyager Coupling Code and external coupling link features installed and operational.
