  • Page 47 Physically, the memory cards are organized as follows: Within a book, memory is organized in two rows (banks) of four memory cards. Since book memory is organized in up to four Processor Memory Arrays (PMAs) and since one memory card only encompasses half a PMA, eight memory cards are needed for a full book with 128 GB.

  • Page 49 If all or part of the additional memory is enabled for installation use, it becomes available to an active logical partition if this partition has reserved storage defined (see 2.5.1, “Reserved storage” on page 86 for more detailed information). Or, it may be used by an already defined logical partition that is activated after the memory addition.

Storage access is interleaved between the storage cards, which tends to equalize storage activity across the IBM System z9 Enterprise Class Technical Guide...
  • Page 61 cards. Each PMA has two ports that each have a maximum bandwidth of 8 GB per second. Each port contains a control and a data bus, in order to further reduce any contention by separating the address and command from the data bus. The memory cards support store protect key caches to match the key access bandwidth with that of the memory bandwidth.
  • Page 62 ETR Attachment Facility (EEAF) designed to provide a dual External Time Reference (ETR) attachment facility. Two ETR cards are automatically shipped when Coupling Links are ordered and provide a dual path interface to the IBM Sysplex Timers, which are used for timing synchronization between systems in a Sysplex environment. This allows continued operation even if a single ETR card fails.
  • Page 63 Superscalar processor A scalar processor is a processor that is based on a single issue architecture, which means that only a single instruction is executed at a time. A superscalar processor allows concurrent execution of instructions by adding additional resources onto the microprocessor to achieve more parallelism by creating multiple pipelines, each working on their own set of instructions.
  • Page 64 This design simplifies error detection during instruction execution, saving additional circuits and extra logic required to do this checking. The z9 EC servers also contain error-checking circuits for data flow parity checking, address path parity checking, and L1 cache parity checking. IBM System z9 Enterprise Class Technical Guide...
  • Page 65 Processor Branch History Table (BHT) The Branch History Table implementation on processors has a key performance improvement effect. The BHT was originally introduced on the IBM ES/9000® 9021 in 1990 and has been improved ever since. The z9 EC server BHT offers significant branch performance benefits. The BHT allows each CP to take instruction branches based on a stored BHT, which improves processing times for calculation routines.
  • Page 66 The key point is that Java and C/C++ applications tend to use IEEE Binary Floating Point operations more frequently than earlier applications. This means that the better the hardware implementation of this set of instructions, the better the performance of e-business applications will be. IBM System z9 Enterprise Class Technical Guide...
  • Page 67 Hardware Decimal Floating Point Base 10 arithmetic is used for most business and financial computation. Floating point computation used for work typically done in decimal arithmetic has involved frequent necessary data conversions and approximation to represent decimal numbers. This has made floating point arithmetic complex and error prone for programmers using it in applications where the data is typically decimal data.

  • Page 75 Important: The zAAP is a specific example of an assist processor that is known generically as an Integrated Facility for Applications (IFA). The generic term IFA appears in panels, messages, and other online information relating to the zAAP. zAAPs and logical partition definitions zAAP processors can be defined as dedicated or shared processors in a logical partition and are always related to CPs of the same partition.
  • Page 76 Software support zAAPs do not change the model capacity identifier of the z9 EC. IBM software product license charges based on the model capacity identifier are not affected by the addition of zAAPs. z/OS Version 1.6 is the minimum level for supporting zAAPs, together with IBM SDK for z/OS Java 2 Technology Edition V1.4.1.
  • Page 77 Option 4: No Java crossover (IFACROSSOVER=NO) This option specifies that a standard CP will not look for Java work before entering the wait state. This option assures that all Java work is done on a zAAP as long as one is available.
  • Page 78 The total number of On/Off CoD Active zIIPs plus zIIPs cannot exceed the number of On/Off active CPs plus the number of CPs plus the number unassigned CPs on a z9 EC server. IBM System z9 Enterprise Class Technical Guide...

The number of zIIPs in a logical partition can be larger than the number of CPs in that logical partition.
  • Page 80 The z9 EC server comes with two spare PUs system wide. Depending on the model, CP, IFL, ICF, zAAP, zIIP, and SAP sparing is completely transparent and requires no operating system or operator intervention. IBM System z9 Enterprise Class Technical Guide...
  • Page 81 With transparent sparing, the status of the application that was running on the failed processor is preserved and will continue processing on a newly assigned CP, IFL, ICF, zAAP, zIIP, or SAP (allocated to one of the spare PUs) without customer intervention. If no spare PU is available, application preservation is invoked.
