Clarification of Parallel Sysplex Pricing Terms and Conditions

January 13, 1998
Announcement Letter Number: A98-0009


Document's Table of Contents:


OVERVIEW

IBM is clarifying requirements that determine whether or not customers qualify for aggregated Parallel Sysplex License Charge Pricing. Qualifying criteria that define the "actively coupled" requirement have been added to the Parallel Sysplex License Charge Exhibit.

Customers that do not meet the qualifying criteria will not get the advantage of aggregating MSUs in calculating PSLC prices.

Planned Availability Date: January 13, 1998

AT A GLANCE

IBM is clarifying requirements to qualify for aggregated Parallel Sysplex License Charge pricing. The clarification of the criteria is intended to provide customers with a more detailed definition of actively coupled so they may more easily determine when they achieve active coupling and qualify for aggregated Parallel Sysplex License Charge pricing.

INTENDED CUSTOMERS

All customers that are currently receiving aggregated Parallel Sysplex pricing, and customers who have outstanding aggregated Parallel Sysplex pricing proposals. This announcement does not affect PSLC charges for single systems or MVS V5 customers not yet on Parallel Sysplex pricing.

DESCRIPTION

The PSLC Exhibit and the Attachment for Parallel Sysplex License Charges require that customer's machines be operating in an "actively coupled" environment to qualify for aggregated PSLC pricing. The criteria clarifies what it means to meet that requirement. Refer to the Notice to Customer section in the Customer Letter for criteria for processors to be considered "actively coupled".

NOTICE TO CUSTOMER

Customer Notification Letter

Notice to IBM Customers January 13, 1998 Clarification of S/390 Parallel Sysplex Pricing Terms and Conditions. IBM is clarifying requirements that determine whether or not customers qualify for aggregated Parallel Sysplex License Charge Pricing. Qualifying criteria that define the "actively coupled" requirement have been added to the Parallel Sysplex License Charge (PSLC) exhibits. For Processors to be considered "actively coupled" the following criteria must be met: 1) All Processors in the Parallel Sysplex must be physically attached via coupling links to a common Coupling Facility from Group B of the PSLC Exhibit and via timer links to a common sysplex timer. Note: If a Coupling Facility is divided into multiple logical partitions (LPAR's), all processors must be attached to the same Coupling Facility LPAR. 2) All OS/390 and MVS/ESA V5 images that are running on the processor in the Parallel Sysplex must have at least one common systems enablement function activated to use the Coupling Facility. Eligible systems enablement functions are listed below: -Application Data Sharing including: -- IMS TM: with IMS DB or DB2 -- CICS: with IMS DB or DB2 or VSAM RLS -- TSO and DB2 data sharing -- An eligible Independent Software Vendor's Data Base from Group C of the PSLC Exhibit. -GRS Star Implementation -JES2 Checkpoint in the coupling facility -RACF database caching -SmartBatch multisystem processing -Automated tape sharing and switching -VTAM Generic Resources -VTAM MULTINODE Persistent Sessions -System logger SYSLOG (OPERLOG) -System logger LOGREC -System logger Resource Recovery Services 3) The configuration and operating modes described in the Exhibit must be the normal mode of operation for the processors. The OS/390 and MVS image(s) running the above eligible Systems enablement function(s) must account for at least 50% of the total OS/390 and MVS workload on each processor. A processor can only be in one Parallel Sysplex for pricing purposes. If the processor is partitioned, and the partitions are in different qualifying Parallel Sysplexes, you may select which Parallel Sysplex the processor will be included in for billing. You must notify your IBM representative when you qualify for aggregated PSLC pricing under these criteria for each sysplex. This announcement does not affect PSLC charges for single systems or MVS V5 customers not yet on Parallel Sysplex pricing. If you already meet this definition of "actively coupled" please confirm this by completing and returning the attached letter to us by March 31, 1998. If you are currently receiving aggregated PSLC pricing and do not meet this definition of "actively coupled", please contact your IBM Representative, who will grant you a grace period in which to take action to meet the criteria. The grace period will vary depending on a number of factors, among them the number of processors and the complexity of the sysplex function you are implementing. If you do not meet the criteria at the end of the grace period you will lose the benefit of aggregated Parallel Sysplex pricing. If you install a new Parallel Sysplex after January 13, 1998, you will receive aggregated PSLC pricing when you notify IBM in writing that this clarified criteria has been met. You may add or upgrade a processor to your existing sysplex for a current workload and continue to receive aggregated PSLC pricing during the grace period. If you add a processor to an existing sysplex for a new workload, this processor will qualify for aggregated PSLC when you meet the criteria. IBM may request verification of Parallel Implementation via RMF or equivalent reports. If you require additional information, please contact your IBM Representative.
