The use of this information or the implementation of any of these techniques is a customer responsibility and depends on the customer's ability to evaluate and inte­ grate them into the customer's operational environment. While each item may have been reviewed by IBM for accuracy in a specific situation, there· is no guarantee that the same or similar results will be obtained elsewhere. Customers attempting to adapt these techniques to their own environments do so at their own ris.k. Reference to PTF numbers that have not been released through the PUT process does not imply general availability. The purpose of including these reference numbers is to alert IBM CPU customers to specific information relative to the implementation of the PTF when it becomes available to each customer according to the normal IBM PTF distribution rules. Performance data contained in this document was determined in a controlled environ­ ment; and therefore, the results which may be obtained in other operating environ­ ments may vary significantly. Users of this document should verify the applicable data for their specific environment.

It is intended for IBM and Customer personnel ·who have planning responsibilities for the installation of any of these processors. The overall design of this document is to provide information about each of the processors and the operating systems and major products that support these processors. This document is structured into seven major chapters: Family Comparisons, Logical Components, Software Considerations, Installation Topics, Partitioning Topics, Virtual Storage Considerations and Bibliography. A brief description of each chapter follows: 1. Family Comparisons - This chapter contains a single page on each of the processors in the IBM 3090 family listing the standard and optional features of each. Also included are comparison summaries of the various models. 2. Logical Components - This chapter focuses on the logical components of the IBM 3090 processor family. A description of each of these components and how they are implemented in each member of the IBM 3090 processor family is provided. The unique implementations include: uniprocessor (120E, 150, 150E, 180, 180E), two-way (dyadic) processor (200, 200E), three-way (triadic) processor (300E), four-way processor (400, 400E), and six-way processor (600E). 3. Software Considerations - This chapter contains an overview of the sup­ porting software for the 3090 family. It describes the changes incorporated into MVS/XA 2.1.3, MVS/XA 2.1.7, MVS/XA 2.2.0, MVS/370 1.3.5, VM/XA Systems Facility, VM/High Performance Option, VM/XA System Product, and the major supporting products (JES, EREP, IOCP, and RMF). 4. Installation Topics - This chapter focuses on the major installation consider­ ations that are pertinent to all models of the IBM 3090 family. 5. Partitioning Topics - This chapter contains considerations that are primarily applicable to the "partitionable" processors in the 3090 family. These are the Models 400, 400E, and 600E. 6. Virtual Storage Assessment - This chapter provides considerations for the use of virtual storage, why it is important not to run out, some recommendations for the current use of virtual storage, a list of IBM products that provide Virtual Storage Constraint Relief (VSCR), and the highlights of the amount of relief expected from some of these products. 7. Bibliography - This chapter contains a bibliography for the 3090 family of processors. There is a description of each document that should assist the reader in choosing which documents should be used for specific points of ref­ erence. Abstract iii iv IBM 3090 Reference Preface The primary intent of this document is to serve as a composite source of plan­ ning and installation reference material for IBM 3090 Processors. The document does not obsolete previously available Systems Center technical bulletins on 3090 processors. Information contained in this document consists of original material and material obtained from other sources, including technical bulletins, flashes, and standard IBM publications. The approach taken by the authors in the preparation of this document was to provide a handy reference for 3090 processor planning and installation informa­ tion that would suffice for most situations. If additional detail on a particular topic is required, then existing Systems Center technical bulletins and standard IBM publications should be used. A list of such documents is provided in Chapter 7, Bibliography.
