The up to 64-way p5-595 server is the new flagship of the product line with nearly three times the commercial performance (based on rperf estimates) and twice the capacity of its predecessor, the IBM Sserver pSeries 690.

  • Page 40: Server Overview

    2.1 Server overview The IBM Sserver p5 590 and 595 provides an expandable, high-end enterprise solution for managing the computing requirements necessary to become an on demand business. With the introduction of the POWER5 architecture, there has been numerous improvements over the previous POWER4 architecture based systems.

  • Page 41: Power4 And Power5 System Structures

    symmetric multi-processor. Going beyond 32 processors with POWER4 architecture could increase interprocessor communication, resulting in higher traffic on the interconnection fabric bus. This can cause greater contention and negatively affect system scalability. Moving the L3 cache reduces traffic on the fabric bus and enables POWER5 processor-based systems to scale to higher levels of symmetric multi-processing.

  • Page 42: Simultaneous Multi-Threading

    Adjustable thread priority Adjustable thread priority lets software determine when one thread should have a greater (or lesser) share of execution resources. The POWER5 processor supports eight software-controlled priority levels for each thread. IBM Eserver p5 590 and 595 System Handbook...

  • Page 43: Dynamic Power Management

    Single threaded operation Not all applications benefit from simultaneous multi-threading. Having threads executing on the same processor does not increase the performance of processor intensive applications or applications that consume all of the chip’s memory bandwidth. For this reason, the POWER5 processor supports the single thread (ST) execution mode.
  • Page 44 SMP scaling requirements dictate a single design to address both environments. POWER5 POWER5 technology is the next generation of IBM 64-bit architecture. Although the hardware is based on POWER4, POWER5 is much more than just an improvement in processor or chip design. It is a major architectural change, creating a much more efficient superscalar processor complex.
  • Page 45 Memory and CPU sharing, a dual clock, and dual service processors with failover capability are examples of the full system design approach for high availability. IBM designed the Sserver p5 system processor, caching mechanisms, memory allocation methods, and full ECC support for buses between chips inside a POWER5 system for performance and availability.

Micro-Partitioning requires the Advanced POWER Virtualization capabilities. 3.2.1 Shared processor partitions The virtualization of processors enables the creation of a partitioning model which is fundamentally different from the POWER4 systems where whole processors are assigned to partitions and are owned by them.

  • Page 82: Power5 Partitioning Concept

  • Page 83 Virtual processors Virtual processors are the whole number of concurrent operations that the operating system can use. The processing power can be conceptualized as being spread equally across these virtual processors. Selecting the optimal number of virtual processors depends on the workload in the partition.

  • Page 85: Uncapped Shared Processor Partitions

    Uncapped partitions An uncapped partition has the same definition of a capped partition, except that the maximum limit of processing capacity limit is a soft limit. That means that an uncapped partition may eventually receive more processor cycles than its entitled capacity.

    A mix of dedicated and shared processors within the same partition is not supported. If you dynamically remove a virtual processor you cannot specify a particular virtual CPU to be removed. The operating system will choose the virtual CPU to be removed. Shared processors may render AIX 5L affinity management useless.

    A mixture of virtual Ethernet connections, real network adapters, or both are permitted within a partition. Virtual Ethernet can only connect partitions within a single system. Virtual Ethernet uses the system processors for all communication functions instead of off loading that load to processors on network adapter cards. As a result there is an increase in system processor load generated by the use of virtual Ethernet.

    This value is the one used to determine how many license entitlements are required for the partition.

    7.1 Service processor functions All IBM Sserver p5 590 and 595 servers are shipped with dual service processor cards. One is considered the primary and the other secondary. They are connected together over the Ethernet ports in the bulk power controller (BPC).

  • Page 193: Platform Initial Program Load

    Since there are dual service processors per CEC, both service processors must be updated when firmware updates are applied and activated using the Apply/Activate command on the HMC. The system power code image (stored on the BPC part of service processor) contains the power code for the frames that house the CEC cages, I/O cages, and clustering switches.

    ASMI sessions can also be opened while partitions are running. It is possible to connect to the service processor using a personal computer as long as the system is connected to the service processor network.
