Note: It is the customer’s responsibility to ensure that the installation of the drawer in the preferred rack or cabinet results in a configuration that is stable, serviceable, safe, and compatible with the drawer requirements for power, cooling, cable management, weight, and rail security. 1.6.1 IBM RS/6000 7014 Model T00 Enterprise Rack The 1.
1.6.2 IBM RS/6000 7014 Model T42 Enterprise Rack The 2.0-meter (79.3-in) Model T42 is the rack that will address the special requirements of customers who want a tall enclosure to house the maximum amount of equipment in the smallest possible floor space. The features that differ in the Model T42 rack from the Model T00 include the following: 42 EIA units (42U) of usable space AC power support only Weight: – T42 base empty rack: 261 kg (575 lb) – T42 full rack: 930 kg (2045 lb) 1.6.
Any remaining space in the rack can be used to install other systems or peripherals, provided that the maximum permissible weight of the rack is not exceeded and the installation rules for these devices are followed. Before placing a p5-570 into the service position, it is essential that the rack manufacturer’s safety instructions regarding rack stability have been followed. Special consideration must be taken to avoid a flange on the top of the rack to clear the front bezel.
Hardware Management Console 7310 Model CR2 The 7310 Model CR2 is a 1U, 19-inch rack-mountable drawer supported in the 7014 Model T00 and T42 racks. The 7310 Model CR2 provides one serial port, two integrated Ethernet ports, and two additional PCI slots. The HMC 7310 Model CR2 has USB ports to connect USB keyboard and mouse devices.
1.7 Statement of direction IBM plans to extend the capabilities of the IBM Sserver p5 product line by introducing support for the i5/OS™ operating system. This support is planned for selected IBM Sserver p5 570 and future high-end IBM Sserver p5 models. i5/OS support will provide additional flexibility for large-scale server consolidation where AIX 5L™ and/or Linux is the primary operating system. i5/OS support will be limited to one processor on selected p5-570 models.
18 p5-570 Technical Overview and Introduction
2 Chapter 2. Architecture and technical overview This chapter discusses the overall system architecture represented by Figure 2-1, with its major components described in the following sections. The bandwidths that are provided throughout the section are theoretical maximums used for reference. You should always obtain real-world performance measurements using production workloads.
2.1 The POWER5 chip The POWER5 chip features single-threaded and multi-threaded execution, providing higher performance in the single-threaded mode than its POWER4 predecessor provides at equivalent frequencies. POWER5 maintains both binary and architectural compatibility with existing POWER4 systems to ensure that binaries continue executing properly and that all application optimizations carry forward to newer systems.
2.1.1 Simultaneous multi-threading As a permanent requirement for performance improvements at the application level, simultaneous multi-threading (SMT) functionality is embedded in the POWER5 chip technology. Developers are familiar with process-level parallelism (multi-tasking) and thread-level parallelism (multi-threads).
POWER5 chips extensively use a fine-grained, dynamic clock-gating mechanism. This mechanism gates off clocks to a local clock buffer if dynamic power management logic knows that the set of latches that are driven by the buffer will not be used in the next cycle. This allows substantial power saving with no performance impact. In every cycle, the dynamic power management logic determines whether a local clock buffer that drives a set of latches can be clock-gated in the next cycle.
2.1.4 CMOS, copper, and SOI technology The POWER5 processor design is a result of a close collaboration between IBM Systems and Technology Group and IBM Microelectronics technologies that enables IBM Sserver p5 systems to give customers improved performance, reduced power consumption, and decreased IT footprint size through logical partitioning. The POWER5 processor chip takes advantage of IBM leadership technology. It is made using IBM 0.13-µm-lithography CMOS.
Figure 2-5 Processor card with DDR1 memory socket layout view There are two system backplanes in the p5-570 system. A GX+ bus planar, which docks vertically into the system planar, is always present in the system. The processor cards dock directly into this backplane from the front. A horizontal backplane exists below the CPU cards that is co-planar with the I/O backplane. This backplane routes the vertical fabric bus between the processor cards.

The processor card running at 1.
2.3 Memory subsystem The p5-570 memory controller is internal to the POWER5 chip. It interfaces to either two (DDR1) or four (DDR2) SMI-II buffer chips and 8 pluggable DIMMs per processor card, as described in 2.2, “Processor cards” on page 23. The minimum memory for a p5-570 processor-based system is 2 GB. The maximum installable memory is 512 GB (using DDR1 memory DIMM technology). The p5-570 total memory depends on the number of available processor cards. Figure 2-7 shows memory slot availability. 2.3.

must remain empty. All GX+ cards are hot-pluggable. The RIO-2 ports are used for I/O expansion to external I/O drawers. The supported I/O drawers are the 7311 Model D10, 7311 Model D11, and 7311 Model D20. The Remote I/O expansion card must be installed starting with the first p5-570 building block. 2.4.2 SP bus In addition to the processor drawer interconnect cable (described in 2.2.
The PCI-X slots in the p5-570 system support hot-plug and Extended Error Handling (EEH). In the unlikely event of a problem, EEH-enabled adapters respond to a special data packet that is generated from the affected PCI-X slot hardware by calling system firmware, which examines the affected bus, allows the device driver to reset it, and continues without a system reboot. 64-bit and 32-bit adapters IBM offers 64-bit adapter options for the p5-570 as well as 32-bit adapters.

planning has been given to any operating-system-related disk layout, such as the AIX Logical Volume Manager, when using disk hot-swap capabilities. For more information, see Problem Solving and Troubleshooting in AIX 5L, SG24-5496. Note: It is recommended that you follow this procedure, after the disk has been deconfigured, when removing a hot-swappable disk drive: 1. Release the tray handle on the disk assembly. 2. Pull out the disk assembly a little bit from the original position. 3.
2.7 External I/O subsystems This section describes the external I/O subsystems, which include the 7311 I/O drawers and the external storage solutions that p5-570 supports. 2.7.1 I/O drawers As described in Chapter 1, “General description” on page 1, the p5-570 system has six internal PCI-X slots.

Each RIO-2 port can operate at 1 GHz in bidirectional mode and is capable of passing data in each direction on each cycle of the port. Therefore, the maximum data rate is 4 GBps per I/O drawer in double barrel mode. There is one default primary RIO-2 loop in any p5-570 building block. This feature provides two Remote I/O ports for attaching up to four 7311 Model D10, 7311 Model D11, or 7311 Model D20 I/O drawers to the system in a single loop.
the p5-570 system. If you have more than one I/O drawer, you continue the loop, connecting the next drawer (or drawers) with the same rule.
IBM 7133 Serial Disk Subsystem (SSA) The p5-570 system supports the Advanced Serial RAID adapter (FC 6230), to attach the IBM 7133 Serial Disk Subsystem Model D40, if migrated from a pSeries system. The IBM 7133 Serial Disk Subsystem Model D40 provides a 4U highly available storage subsystem for pSeries servers and is a good solution for providing disks for booting additional LPARs. Disks are available from 18.2 GB to 72.8 GB at the time this publication was written.
2.8 Dynamic logical partitioning The logical partition (LPAR) was introduced with the POWER4 processor product line and the AIX 5L Version 5.1 operating system. The technology offered the capability to divide a pSeries system into separate systems, where each LPAR runs an operating environment on dedicated attached devices, such as processors, memory, and I/O components.
The Advanced POWER Virtualization feature includes: Firmware enablement for Micro-Partitions Installation image for the Virtual I/O server software that supports: – Ethernet adapter sharing – Virtual SCSI Server Partition Load Manager – Automated CPU and memory reconfiguration – Real-time partition configuration and load statistics – Graphical user interface Micro-Partitioning technology POWER5-based servers introduces an enhanced partitioning model that is based on the partitioning concepts of a sta

Note: The Shared Ethernet adapter and Virtual SCSI server functions are provided in the Virtual I/O Server that is included in the Advanced POWER Virtualization feature (FC 7942), an additional feature of p5 systems. Partition Load Manager The Partition Load Manager (PLM) is part of the Advanced POWER Virtualization feature. It provides automated processor and memory distribution between dynamic LPAR and Micro-Partitioning capable logical partition running AIX 5L.

2.11 Boot process From the earlier RS/6000 systems, through the previous pSeries systems, the boot process passed through several enhancements. With the implementation of the POWER5 technology, the boot process is enhanced to accommodate the flexibility that the POWER5 processor-based hardware features. Depending on the customer’s needs, a system may or may not require the use of an HMC to manage the system.
– Boot to open firmware prompt – Boot to System Management Service (SMS) to further select the boot devices or network boot options Boot to server firmware – Select the state for the server firmware: Standby or Running. – When the server is in the server firmware standby state, partitions can be set up and activated. 2.11.2 Hardware Management Console Depending on the model, the HMC provides several native serial ports and Ethernet ports. One serial port may be used to attach a modem for Service Agent.
– When the Partition Standby power-on is completed, the operator panel on the managed system displays LPAR..., indicating that the managed system is ready for you to use the HMC to partition its resources and, possibly, activate them. – When a partition is activated, the HMC requires you to select the boot mode of the single partition. System Profile The System Profile option powers on the system according to a predefined set of profiles.
– To enhance the flexibility to use the system within several different logical configurations, a System profile could be defined to collect more than one Partition profile to provide requested system behavior. 2.11.5 Hardware requirements for partitioning To implement partitioning on a POWER5-based system, resource planning is important to ensure that you have a base configuration and enough flexibility to make desirable changes to the running logical partitions.
The p5-570 (or the logical partition) must be equipped with either a graphic adapter that is connected to a graphics display, keyboard, and mouse device, or an ASCII display terminal that is connected to one of the native serial ports or the attached HMC to use the SMS menus. You can view information about the system (or the single logical partition) and perform tasks such as set a password, change the boot list, and set the network parameters.
partition displays the SMS menus, all of the necessary tests have been performed and the machine is scanning the bus for a boot source. Most system backplanes are designed such that the drive in the first slot spins up immediately after power-on, and other drives will wait for the operating system to send a command before spinning up. Disk drive bays 1 and 4 are hard-wired to spin up immediately.
available to the specific partition, using mksysb, for example. SCSI disk, and Virtual SCSI disk The more common method of booting the system is to use a disk situated in one of the hot-swap bays in the front of the machine. However, any external SCSI-attached disk could be used if required. As described in previous sections, Virtual SCSI devices are also available to a logical partition. SSA disk The p5-570 supports booting from an SSA disk either as an AIX system disk or as a RAID LUN.
IBM periodically releases maintenance packages for the AIX 5L operating system. These packages are available on CD-ROM (FC 0907) and can be downloaded from the Internet at: http://techsupport.services.ibm.com/server/fixes You can also get individual operating system fixes and information about obtaining AIX 5L service at this site. AIX5L Version 5.3 has the suma command, which helps the administrator to automate the task of checking and downloading operating system downloads.
3 Chapter 3. Capacity on Demand, RAS, and manageability The following sections provide more detailed information about IBM Sserver p5 design features that help lower total cost of ownership (TCO). This chapter includes several features that are based on the benefits that are available when using AIX 5L. Support of these features using Linux can vary. © Copyright IBM Corp. 2004. All rights reserved.
3.1 Capacity on Demand p5-570 systems can be shipped with non-activated resources (processors and memory), which may be added as they are needed. Processors and memory can be brought online to meet increasing workload demands without affecting system operations. The CoD is supported on p5 Model 570 when the 1.65 GHz and 1.9 GHz Power5 processors are used.
Capacity Upgrade on Demand In Capacity Upgrade on Demand (CUoD), processors are shipped to the customer as installed in the p5-570, and can be activated later in increments of one processor. Additional options deliver the possibility to temporarily use the processor resources that are installed in the server. All processor cards are 2-way, with 0-way active. In an initial order of the p5-570 system, at least two processors must be activated by ordering the appropriate activation features.
On/Off Capacity on Demand The On/Off memory enablement feature is ordered and the associated enablement code is entered into the system. On/off usage must be reported to IBM at least monthly. This information, which is used to compute your billing data, is then provided to the sales channel, which will place an order for a quantity of On/Off Memory day billing features. One FC 7957 should be ordered for each billable day and for each 1GB increment of DDR1 memory.
Using e-mail 3.1.4 Trial Capacity on Demand Customers with CUoD featured systems must purchase the activation codes from IBM before the non-activated CUoD resources can be activated to meet the increased workload. However with the Trial Capacity on Demand feature, customers can activate the required non-activated CUoD resources immediately and, after that, proceed to purchase those resources from IBM or not. The HMC calls this feature Activate Immediate.
3.2.2 First Failure Data Capture If a problem should occur, the ability to diagnose it correctly is a fundamental requirement upon which improved availability is based. The p5-570 incorporates advanced capability in start-up diagnostics and in run-time First Failure Data Capture (FDDC) based on strategic error checkers built into the chips.
operating system has lost control. Mutual surveillance also enables the operating system to monitor for service processor activity and can request a service processor repair action if necessary. Environmental monitoring Environmental monitoring related to power, fans, and temperature is performed by the System Power Control Network (SPCN). Environmental critical and non-critical conditions generate Early Power-Off Warning (EPOW) events.
(dynamic bit-steering). Memory scrubbing is the process of reading the contents of the memory during idle time and checking and correcting any single-bit errors that have accumulated by passing the data through the ECC logic. This function is a hardware function on the memory controller chip and does not influence normal system memory performance. 3.2.
If the output shows CPU Guard as disabled, enter the following command to enable it: chdev -l sys0 -a cpuguard='enable' Cache or cache-line deallocation is aimed at performing dynamic reconfiguration to bypass potentially failing components. This capability is provided for both L2 and L3 caches. Dynamic run-time deconfiguration is provided if a threshold of L1 or L2 recovered errors is exceeded.

It reports detected errors, assuming that they meet certain criteria for criticality, to IBM for service with no customer intervention. It is an enhanced version of Service Director™ with a graphical user interface.
checks the current customer service status from the IBM entitlement database; if this reveals that you are not under warranty or MA, then the service call is refused and posted back using e-mail. Service focal point Service Focal Point is used by service technicians to start and end their service calls. It provides service representatives with event, Vital Product Data (VPD), and diagnostic information.
3.4 Cluster 1600 Today's IT infrastructure requires that systems meet increasing demands while offering the flexibility and manageability to rapidly develop and deploy new services. IBM clustering hardware and software provide the building blocks, with availability, scalability, security, and single-point-of-management control, to satisfy these needs.
Some customers expanded the use of their dedicated systems and consequently model more business processes. This often caused an increased number of dedicated systems that were used and a stronger demand on flexibility. In addition, the life cycle of these systems differed extremely. Renaming, removal, and deletion became more and more common system administration tasks. In 2001, the pSeries hardware technology with logical partitioning was generally available.
