Notes on Benchmarks and Values
The benchmarks and values shown herein were derived using particular, well configured, development-level computer systems. Unless otherwise indicated for a system, the values were derived using external cache, if external cache is supported on the system. Buyers should consult other sources of information to evaluate the performance of systems they are considering buying and should consider conducting application oriented testing. For additional information about the benchmarks, values and systems tested, contact your local IBM office or IBM authorized reseller or access the following on the Web: TPC Linpack Pro/E SPEC GPC NotesBench Mail VolanoMark STREAM Unless otherwise indicated for a system, the performance benchmarks were conducted using AIX V4.3 or AIX 5L. IBM C Set++ for AIX and IBM XL FORTRAN for AIX with optimization were the compilers used in the benchmark tests. The preprocessors used in some benchmark tests include KAP 3.2 for FORTRAN and KAP/C from Kuck & Associates and VAST-2 v4.01X8 from Pacific-Sierra Research. The preprocessors were purchased separately from these vendors. Other software packages like IBM ESSL for AIX and MASS for AIX were also used in some benchmarks. The following SPEC and Linpack benchmarks reflect microprocessor, memory architecture, and compiler performance of the tested system (XX is either 95 or 2000): SPECintXX - SPEC component-level benchmark that measures integer performance. Result is the geometric mean of eight tests comprising the CINTXX benchmark suite. All of these are written in the C language. SPECint_baseXX is the result of the same tests as CINTXX with a maximum of four compiler flags that must be used in all eight tests. SPECint_rateXX - Geometric average of the eight SPEC rates from the SPEC integer tests (CINTXX). SPECint_base_rateXX is the result of the same tests as CINTXX with a maximum of four compiler flags that must be used in all eight tests. SPECfpXX - SPEC component-level benchmark that measures floating-point performance. Result is the geometric mean of ten tests, all written in FORTRAN, included in the CFPXX benchmark suite. SPECfp_baseXX is the result of the same tests as CFPXX with a maximum of four compiler flags that must be used in all ten tests. SPECfp_rateXX - Geometric average of the ten SPEC rates from SPEC floating-point tests (CFPXX). SPECfp_base_rateXX is the result of the same tests as CFPXX with a maximum of four compiler flags that must be used in all ten tests. SPECweb96 - Maximum number of Hypertext Transfer Protocol (HTTP) operations per second achieved on the SPECweb96 benchmark without significant degradation of response time. The Web server software is ZEUS v.1.1 from Zeus Technology Ltd. SPECweb99 - Number of conforming, simultaneous connections the Web server can support using a predefined workload. The SPECweb99 test harness emulates clients sending the HTTP requests in the workload over slow Internet connections to the Web server. The Web server software is Zeus from Zeus Technology Ltd. SPECweb99_SSL - Number of conforming, simultaneous SSL encryption/decryption connections the Web server can support using a predefined workload. The Web server software is Zeus from Zeus Technology Ltd. SPEC OMP Measures performance based on OpenMP applications. SPECsfs97_R1 - Measures speed and request-handling capabilities of NFS (network file server) computers. Revised May 28, 2003

Notes on Benchmarks and Values (Cont.)
SPECjAppServer200X (where X is 1 or 2) - Measures the performance of Java Enterprise Application Servers using a subset of J2EE APIs in a complete end-to-end Web application. The Linpack benchmark measures floating-point performance of a system. Linpack DP (Double Precision) - n=100 is the array size. The results are measured in megaflops (MFLOPS). Linpack SP (Single Precision) - n=100 is the array size. The results are measured in MFLOPS. Linpack TPP (Toward Peak Performance) - n=1,000 is the array size. The results are measured in MFLOPS. Linpack HPC (Highly Parallel Computing) - solves the largest system of linear equations possible. The results are measured in GFLOPS. STREAM is a simple synthetic benchmark program that measures sustainable memory bandwidth (in MB/s) and the corresponding computation rate for simple vector kernels. Both standard and tuned results may be reported. VolanoMark is a 100% pure Java server benchmark that creates long-lasting network client connections in groups of 20 and measures how long it takes for the clients to take turns broadcasting their messages to the group. The benchmark reports a score as the average number of messages transferred by the server per second. The following Transaction Processing Performance Council (TPC) benchmarks reflect the performance of the microprocessor, memory subsystem, disk subsystem, and some portions of the network: tpmC - TPC Benchmark C throughput measured as the average number of transactions processed per minute during a valid TPC-C configuration run of at least twenty minutes. $/tpmC - TPC Benchmark C price/performance ratio reflects the estimated five year total cost of ownership for system hardware, software, and maintenance and is determined by dividing such estimated total cost by the tpmC for the system. QppH is the power metric of TPC-H and is based on a geometric mean of the 17 TPC-H queries, the insert test, and the delete test. It measures the ability of the system to give a single user the best possible response time by harnessing all available resources. QppH is scaled based on database size from 30GB to 10TB. QthH is the throughput metric of TPC-H and is a classical throughput measurement characterizing the ability of the system to support a multiuser workload in a balanced way. A number of query users is chosen, each of which must execute the full set of 17 queries in a different order. In the background, there is an update stream running a series of insert/delete operations. QthH is scaled based on the database size from 30GB to 10TB. $/QphH is the price/performance metric for the TPC-H benchmark where QphH is the geometric mean of QppH and QthH. The price is the five-year cost of ownership for the tested configuration and includes maintenance and software support. Revised February 6, 2004

The following graphics benchmarks reflect the performance of the microprocessor, memory subsystem, and graphics adapter: SPECxpc results - Xmark93 is the weighted geometric mean of 447 tests executed in the x11perf suite and is an indicator of 2D graphics performance in an X environment. Larger values indicate better performance. SPECplb results (graPHIGS) - PLBwire93 and PLBsurf93 are geometric means of literal and optimized Picture Level Benchmark (PLB) tests for 3D wireframe and 3D surface tests, respectively. Larger values indicate better performance. SPECopc results - Viewperf 7 (3dsmax-01, DRV-08, DX-07, Light-05, ProE-01, UGS-01) and Viewperf (AWadvs-04, DRV-07, DX-06, Light-04, medMCAD-01, ProCDRS-03) are weighted geometric means of individual viewset metrics. Larger values indicate better performance. The following graphics benchmarks reflect the performance of the microprocessor, memory subsystem, graphics adapter and disk subsystem. SPECapc Pro/Engineer 2000i2 results - PROE2000I2_ was developed by the SPECapc committee to measure UNIX and Windows workstations in a comparable real-world environment. Larger numbers indicate better performance. The NotesBench Mail workload simulates users reading and sending mail. A simulated user will execute a prescribed set of functions 4 times per hour and will generate mail traffic about every 90 minutes. Performance metrics are: NotesMark - transactions/minute (TPM). NotesBench users - number of client (user) sessions being simulated by the NotesBench workload. $/NotesMark - ratio of total system cost divided by the NotesMark (TPM) achieved on the Mail workload. $/User - ratio of total system cost divided by the number of client sessions successfully simulated for the NotesBench Mail workload measured. Total system cost is the price of the server under test to the client, including hardware, operating system, and Domino Server licenses. Application Benchmarks SAP - Benchmark overview information: Benchmark White Paper September, 2000; PeopleSoft - To get information on PeopleSoft benchmarks, contact PeopleSoft directly or the PeopleSoft/IBM International Competency Center in San Mateo, CA. Oracle Applications - Benchmark overview information: Baan - The Baan benchmark demonstrates the scalability of Baan ERP solutions. The test results provide the number of Baan Reference Users (BRUs) that can be supported on a specific system. BRU is a single on-line user or a batch unit workload. These metrics are consistent with those used internally by both IBM and Baan to size systems. To get more information on Baan benchmarks, go to J.D.

Notes on Performance Estimates
rPerf rPerf (Relative Performance) is an estimate of commercial processing performance relative to other pSeries systems. It is derived from an IBM analytical model which uses characteristics from IBM internal workloads, TPC and SPEC benchmarks. The rPerf model is not intended to represent any specific public benchmark results and should not be reasonably used in that way. The model simulates some of the system operations such as CPU, cache and memory. However, the model does not simulate disk or network I/O operations. rPerf estimates are calculated based on systems with the latest levels of AIX 5L and other pertinent software at the time of system announcement. Actual performance will vary based on application and configuration specifics. The IBM ~ pSeries 640 is the baseline reference system and has a value of Although rPerf may be used to approximate relative IBM UNIX commercial processing performance, actual system performance may vary and is dependent upon many factors including system hardware configuration and software design and configuration. All performance estimates are provided "AS IS" and no warranties or guarantees are expressed or implied by IBM. Buyers should consult other sources of information, including system benchmarks, and application sizing guides to evaluate the performance of a system they are considering buying. For additional information about rPerf, contact your local IBM office or IBM authorized reseller. Revised June 28, 2004

Organizations must adjust to unpredictable demands effectively. IBM pSeries on demand technology is fundamentally about flexibility. From an enhanced functionality perspective, the capacity on demand offerings announced in May and October of are exactly what the market needs. And, our dynamic LPAR capabilities will be expanded through unique virtualization capabilities. UNIX systems today are often underutilized. IBM pSeries is enabling customers to improve this situation today with dynamic LPAR. For example, customers can set up virtual servers immediately for quick application deployment. They can dynamically increase or decrease resources whenever necessary without disrupting the business. Dynamic LPAR essentially allocates the processing power where it’s needed in a flexible and efficient manner like never before. And tomorrow IBM plans for virtualization to improve significantly with POWER5-based technology. POWER5 itself is a virtualization enabler designed to allow uncapped partitions in shared processor pools, and up to 10 logical partitions per processor with a potential total of 254 partitions in a single system. Virtual I/O, LAN and storage will represent complete virtual integration that’s changing the definition of workload flexibility.

IBM ~ p5 550 Reliability Availability and Serviceability

Reliability Availability Serviceability (RAS)
Fault avoidance - designed to avoid downtime Diagnose failures if they happen Resolve intermittent faults with no intervention Deallocate system resources if necessary Utilize system redundancies Online parts replacement Keep the system operational! Online firmware updating

Reliability Availability Serviceability*
RAS enhancements available on POWER5 servers Applications remain operational while IBM system firmware is updated for most operations (planned for 4Q04) ECC has been extended to inter-chip connections for the Fabric/processor busses (data, address, control) Partial L2 cache deallocation L3 cache line deletes improved from two to ten for better self-healing capability *Note: some RAS functions may not be available at the same time on Linux SLES 9 and RHEL 3.3

A Self-diagnosing Server
First Failure Data Capture is key to a self-diagnosing system and is an IBM exclusive! Critical parts of system can provide real-time machine status information if faults occur Error data is continually being monitored by system in order to take appropriate actions Many errors can be self-corrected or functions varied offline while server remains available Server has capability to determine which part or component needs repair and can phone IBM Service to provide precise parts for maintenance at a time acceptable to client

Reliability Availability Serviceability
24x7 Fault Avoidance Fault Masking Resource Deallocation Concurrent Maintenance N+1 Redundancy Service Productivity First Failure Data Capture Self- Healing

Capture Error Causes in Real-time
First Failure Data Capture Cornerstone that is basis of pSeries RAS technology First Failure Data Capture provides error information in real-time and makes it possible to determine parts necessary to fix problem Trying to recreate intermittent errors at a later time can be extremely time consuming, ineffective, and sometimes impossible

First Failure Data Capture Technology
Old Failure Recreate Strategy Run diagnostic test cases during service call Repair based on test case symptom Questionable correlation to original problem Development focus on improved test cases Open service action plan if failure not recreated Test cases used to try to isolate failures and verify correct operation First Failure Data Capture: an IBM Exclusive Specialized hardware designed to capture failure data at time of failure Repair based on root-cause analysis Direct correlation to original client problem Engineering focus on built-in error detection and capture Service action plan driven by captured failure information Test cases used to only to verify correct operation CPU L1 Cache L2/L3 Cache Memory Disk Error Checkers Fault Isolation Register (FIR) (unique fingerprint of each error captured) Service Processor Log Error Nonvolatile RAM Reliably identify each failing component, reducing costly downtime

Start Off With Quality-based Design
Fault Avoidance Designing extra quality into system to keep errors from ever happening Mainframe-inspired components and technologies - Designed for reduced power consumption, cooler operating temperatures and increased reliability

An Active Server Immune System
Self- Healing Bit-steering to redundant memory in event of failed memory module to keep server operational Single bit error correction via ECC without reaching error thresholds for main, L2 and L3 cache memories L3 cache line deletes extended from two to ten for additional self healing ECC extended to inter-chip connections on fabric/processor busses Soft-error scrubbing to help prevent memory faults

.... X ECC Memory Integrity and Availability X Chipkill
Memory scrubbing for soft single-bit errors that are corrected in the background while memory is idle, to help prevent multiple-bit errors. Dynamically reassign memory I/O via bit-steering if error threshold is reached on same bit Failing memory bit steered to spare memory bit Chipkill .... X Spare memory bits X Scatter memory chip bits across four separate ECC words for Chipkill recovery Bit-scattering allows normal single bit ECC error processing, thereby keeping system running with a Chipkill failure. Bit-steering allows memory lines from spare memory bits to be dynamically reassigned to a memory module with a faulty line to keep system running. If all spare bits are utilized, and threshold is reached, the Service Processor will be invoked to request deferred maintenance at a time acceptable to client.

Built-in Redundancies Designed for Non-stop Operation
Redundancy Use of redundancy to remain operational with full resources Redundant spare memory bits Redundant fans - Fans will speed up to try to compensate for failed fan Redundant power supplies (optional)

Continued Operation and System Integrity
Fault Masking Corrections and retries that don't exceed threshold limits and don't require client or IBM CE intervention CEC bus retry and recovery PCI-X bus recovery ECC Chipkill soft errors

Keep Running With Fewer Resources
Deallocation If threshold reached, resources can be deallocated with system remaining operational, allowing client to plan maintenance at a convenient time Partial L2 cache deallocation PCI-X bus deallocation to the card level Removal and replacement of failed PCI-X cards Upon reboot, failed components will be deconfigured to avoid repeat of errors

X PCI Bus and Card Error Recoveries
PCI-X Controller X Problem with damaged connection results in PCI-X bus error - That particular slot is varied offline by system - All other slots remain active - System stays operational without the slot active - If PCI card is damaged, replace with new one - If slot is damaged, plan for maintenance at client’s convenience

Replacement of Parts While System Runs
Concurrent Maintenance Online hot-plug of defective electromechanical components keeps system operational Disk drives Cooling fans Power subsystems PCI, PCI-X adapter cards

Quicker Service for Client Convenience
Productivity Increasing service productivity means more client uptime Most firmware updates may be made while the server remains operational (planned for 4Q04) Internal LED diagnostics identify components that require service LEDs on I/O provide status of PCI-X slots and disk drives for power, hot-swap and need for service
