xxviii iSeries Handbook

Introduction

The iSeries features a unique design that delivers the benefits of today’s innovative technology without complexity. With V5R1, this design has been extended to take advantage of the latest industry leading technology and new OS/400 capabilities.

In the year 2000, the IBM significantly accent the evolution of the IBM server product line. SStar processors refreshed the iSeries models to run faster than the iStar processors.

With V5R1, there are new, more powerful processor features based on IBM’s industry leading Copper/Silicon on Insulator (SOI) technology, and increased disk and memory capacities provide increased performance and scalability. New Capacity Upgrade on Demand options on the Model 840 allow the activation of processor performance as it is needed.

Storage options are enhanced. The Storage Area Network (SAN) environment is supported using Fibre Channel disk and tape adapters. Faster, less expensive, system-to-system clustering with High Speed Link (HSL) OptiConnect brings increased high availability. With switchable disk clusters, the need for redundant data is reduced.

OS/400 V5R1 provides some of the industry’s foremost application flexibility, with support for Linux, Lotus Domino, Java, Microsoft Windows, Unix, and iSeries applications. High availability is combined with superior workload management and logical partitioning.

OS/400 V5R1 and the iSeries server stand out with robust reliability and scalability for the fast growing open source Linux environment. Users can quickly deploy PowerPC Linux applications while taking advantage of iSeries reliability and scalability.

Up to thirty-two partitions on a single iSeries server and dynamic resource allocation permit different applications to run safely and efficiently side by side. Options for managing windows application serving are greatly enhanced with the new integrated server options. An iSeries server can be attached to up to sixteen direct attach n-way xSeries servers, or up to thirty-two internal Integrated xSeries Servers, and provide SAN functions for these directly attached Windows 2000 servers.

~ iSeries Models 270 and 8xx were introduced to

OS/400 V5R1 includes a broad range of enhancements for e-business and application enablement, OS/400 PASE, XML, Client Access, directory services, IBM HTTP Server (powered by Apache), database, Java, Internet printing, Extreme Support Personalized (ESP) enhancements. These enrichments include:

• Faster processors to boost top performance on Models 270, 820, and 840.

• Three new base processors on the Model 820 designed for compute-intensive

workloads.

Pools (iASP), to provide high availability and redundant data options for integrated file system applications, such as Lotus Domino and Web serving.

• Operations Console with LAN connectivity to deliver more flexibility for distributed and

LPAR environments.

• Fibre Channel Adapters allow attachment to external tape and disk subsystems, and

enhance the iSeries ability to participate in Storage Area Networks (SAN).

• Logical Partitioning (LPAR) is now available on selected uni-iSeries processors,

including the Model 270. LPAR now supports dynamic resource movement, resource sharing and virtual LAN.

• Linux on iSeries brings iSeries integration, scalability, and robust availability to Linux.

Linux enables a new generation of Web based applications with resource sharing and management via Logical Partitions.

• Windows Server Integration is enhanced to allow the connection of external 4-way

xSeries servers with an Integrated xSeries Adapter via HSL, and the ability to run up to 32 Integrated xSeries Servers inside a single iSeries server.

• Lotus Domino Server for iSeries now supports iNotes access for Microsoft Outlook

clients. This allows those iNotes clients to take advantage of the additional functions and reliability of a Domino server running on iSeries. Lotus Domino Server for iSeries is enhanced with support for incremental Domino saves, improved BRMS, EZ-Setup Wizard for Domino, TCP/IP Autostart, and an incremental installer.

• WebSphere Development Studio for iSeries has all the key tools for e-business

development in one “attractively priced” package. It includes the WebFacing Tool as a quick, easy to use tool to convert 5250 applications to Web GUI applications.

• WebSphere Transcoding Publisher to optimize the wireless Web experience. Extend

existing Web content to new devices and markets without re-authoring expenses. Deliver efficient content to a variety of users across wireless networks.

• Connect for iSeries extends business to business capabilities. Plug into

e-marketplaces, integrate into existing back-end systems, take advantage of new trading protocols, and add incremental B2B function to applications.

The new technologies behind iSeries Models 270 and 8xx expand the range for processor power, main storage, DASD storage, and communications speeds far beyond the current range of scalability – to extreme scalability. With this expanded range of scalability, you have the power and flexibility to integrate a variety of modern computing environments, from core business to e-business, in a very cost effective way, without concern for limits within a single server. The broad range of hardware migration support protects the investments you have with the iSeries.

This Handbook provides an overview of both the hardware and software for the newly refreshed iSeries servers. Included are the 9406 250, 270, 820, 830, 840, SB2, and SB3 models. OS/400 V5R1 operating software supports these models.

iSeries Technology in Stride

The iSeries server delivers tremendous capacity growth in its product line. The iSeries Layer (also known as Technology Independent Machine Interface (TIMI)) has made it possible to completely change the underlying hardware with minimum, if any, impact to iSeries applications. TIMI helps condition the iSeries to bring new technology to market.

The first AS/400e models based on the 64-bit RISC PowerPC AS processors were announced in June 1995. The ease with which customers have migrated to these powerful systems is a testimony to the fundamental strength of the server’s architecture.

In 1997, the 12-way AS/400e system was delivered using Power PCA35 microprocessors. Known as Apache technology, the Power PCA35 microprocessors provided a growth of 4.6 times.

In September 1998, the 12-way AS/400e system was delivered using the Power PCA50 microprocessor. Known as code name Northstar, the Power PCA50 microprocessors nearly doubled the high-end capacity. This set of processors provided the fourth generation since the AS/400 system’s inception in 1988 with 64-bit AS/400 Power PCs microprocessors.

The advance in processor technology is shown in the following figure.

Again in 2000, the iSeries lead the industry by delivering the first server with the new “Silicon-on-Insulator” (SOI) technology. SOI represents a fundamental advance in the way chips are built. IBM's unique SOI process alters the design of transistors, essentially “turbo charging” them, so they run faster and use less power. For example, a microprocessor designed to operate at a given speed can instead be built using SOI technology to achieve higher speeds. At the same time, if performance levels are held constant, SOI chips can require as little as one-third the power of today's microchips. Silicon on Insulator is technology used by the iStar processors. The transistors are built within and on top of a thin layer of silicon that is on top of an insulating layer. The insulating layer is fabricated by implanting a thin layer of oxide beneath the primary silicon surface of the wafer.

Pulsar, iStar, and SStar processors use on-chip copper-wiring technology. The Pulsar processors integrate IBM CMOS7S technology. iStar and SStar processors integrate CMOS8S technology. Previously, Northstar technology used aluminum for on-chip wiring. Copper's better conductivity permits thinner wires to be used, which enables the transistors to be packed closer together. The denser new technology permits additional micro-architecture methods to improve performance.

Keeping multiple levels of high speed cache is still necessary to keep the processors busy. Denser processor technology permits more on-chip cache. All this new technology is implemented on the new iSeries servers.

iSeries Architecture: Fundamental Strength of the iSeries

The iSeries servers and supporting software offer important advanced capabilities in such key areas as Java, Web serving, Lotus Domino, integration with Windows NT, managed availability, database, and Business Intelligence solutions. The iSeries solution continues to be a strong performer in such growing areas as data warehousing and the Internet. To gain an appreciation of these technologies and of the particular strength of the iSeries server in delivering them, this chapter provides a summary of each prime element.

With over 650,000 systems shipped worldwide, the iSeries servers have the highest customer satisfaction index in the industry, as measured by IBM internal studies. Ten major factors contributing to this include:

• Offers state-of-the-art 64-bit relational database processing.

• Leads the industry in delivering the first server with Silicon on Insulator (SOI)

technology.

• Allows the deployment of Java, UNIX ported applications, Windows 2000,

Domino-based applications, and Linux on a single server.

• Directly (natively) supports different file structures, such as PC files, UNIX files,

NetWare files, Domino files, ASCII files, and EBCDIC files.

• Can ship with over 200 processor chips under the covers of a “single” large system.

• Can have 32 Windows NT servers in a single system while sharing host systems disk

storage, tape, and CD-ROM resources.

• Its object-based design makes it highly virus resistant.

• Has proven it can deliver over 99.9% availability.

• Its operating system can operate for more than one year without ever requiring a

re-IPL, in hundreds of customer shops.

• Delivers vector coded indexes for Business Intelligence applications offering up to ten

times the improvement in performance.

Why should the system architecture matter to a business person? This section helps you understand why.

Business leaders do not grow their business by simply choosing a computer system. They start by choosing an application to fit their business goals and needs. iSeries customers have tens of thousands of proven business applications worldwide. Because of that, very often the computer system is considered first.

If you compared an application running on an iSeries server to the same application running on a non-iSeries server, you would continue to choose the iSeries. Why? Because, although

iSeries Architecture: Fundamental Strength of the iSeries

two systems can appear to be equivalent today, the accelerating rate of change of both hardware and software technologies necessitates that the server you select is designed with the future in mind. The iSeries accommodates inevitable, rapid, and dramatic technology changes with minimum relative customer effort.

Paradoxically, the characteristic of the most advanced design and technology is that you do not notice it... you are not meant to do so. It accommodates rapidly-changing hardware and software technologies in stride — permitting you to fully exploit the latest technologies.

• Customers typically decide on the required application software first and then select

an environment in which to run it. The iSeries models have tens of thousands of business applications worldwide of which thousands are client/server applications. These applications are written by thousands of IBM Business Partners across the globe. In addition, the iSeries server provides excellent platforms for Windows NT and Lotus Domino applications. iSeries models have national language support for over 50 languages, available in 140 countries. Support across the world is provided by an impressive network of global partners.

iSeries Architecture

Technology Independent Machine Interface

The iSeries servers are atypical in that they are defined by software, not by hardware. In other words, when a program presents instructions to the machine interface for execution, it “thinks” that the interface is the system hardware. But it is not! The instructions presented to that interface pass through a layer of microcode before they are “understood” by the hardware itself.

This comprehensive design insulates application programs and their users from changing hardware characteristics. When a different hardware technology is deployed, IBM rewrites sections of the microcode to absorb the fluctuations in hardware characteristics. As a result, the interface presented

to the customer remains the same

This interface is known as the iSeries Layer, or Technology Independent Machine Interface (TIMI). The microcode layer is known as the System Licensed Internal Code (SLIC).

Many of the frequently-executed routines run in SLIC. Supervisory resource management functions

Programs

in SLIC include validity and authorization checks. On a customary system, these routines reside in the operating system. Because SLIC is closer to the

TIMI

silicon, routines performed there are faster than routines placed “higher” in the machine.

SLIC

The brilliance of this design was dramatically illustrated when the AS/400 system changed its processor technology from Complex Instruction Set

64-bit RISC Hardware

Computing (CISC) processors to 64-bit Reduced Instruction Set Computing (RISC) processors in

1995. With any other system, the move from CISC to RISC would involve recompiling (and possibly some rewriting) of programs. Even then, the programs would run in 32-bit mode on the newer 64-bit hardware.

This is not so with the iSeries server, because of TIMI. Customers were able to programs off their CISC AS/400 systems, and

Hierarchy of Microprocessors

The iSeries servers are designed for business computing. One of the fundamental characteristics of that environment is that it is I/O-intensive, rather than compute-intensive. In addition to outstanding performance in the business environment, the microprocessor hierarchy design gives the iSeries server an elegant method of integrating diverse environments into a single, harmonious customer solution.

The microprocessors that look after a particular I/O device are accommodated on I/O cards that fit into slots on the system buses. One of these cards may be the Integrated xSeries Server. This is a PC on a card, which enables the iSeries to run a Windows NT server, for example.

The following figure shows a range of iSeries processors dedicated to a particular input/output (I/O) device type.

A single large iSeries configuration can have well over 200 processors. The main system processor complex (can be comprised of 24 separate processors) can encounter a request for data to be read from or written to any I/O device. That request for data is delegated to the particular microprocessor dedicated to that I/O device. Meanwhile, the main system

iSeries Architecture: Fundamental Strength of the iSeries

processor continues executing another application program. Nanoseconds (10-9 second) is the unit of time used to measure main storage access times. I/O operations are measured in

-3

milliseconds (10

second).

The previous figure shows a high-level overview of the structure of the iSeries 840 model. Central in the figure is the extremely high speed memory-processor-I/O interconnect switch at 43.2 GB/sec. This allows for data transfers between components connected to the switch to proceed at a very high rate. Separate connections to the switch are provided for each group of six processors, each of four banks of memory, and two connections for I/O traffic. These independent paths result in much superior performance than previous designs with a single common shared memory bus path, for which all components contended.

With the new design, there are many paths to the high speed switch, which can operate separately. Its high bandwidth characteristics allow for connecting source and destination quickly and efficiently to allow for significant benefit in overall processor speed and system performance enhancement. This design provides the iSeries server with outstanding performance in the commercial, transaction-based environment.

Single-level Storage

Application programs on an iSeries server are unaware of the underlying hardware characteristics, because of the iSeries Layer (or TIMI) (see “Technology Independent Machine Interface” on page 13). Applications are also unaware of the characteristics of any storage devices on the system because of single-level storage.

As with TIMI, the concept of single-level storage means that the knowledge of the underlying characteristics of hardware devices (in this case, main storage and disk storage) reside in the SLIC. All of the storage is automatically managed by the system. No user intervention is ever needed to take full advantage of any storage technology. Programs work with objects (see “Object-based” on page 18). Objects are accessed by name, not by address.

The iSeries server address size is vast. iSeries models can address the number of bytes that

64 bits allows it to address. The value 2

is equal to 18,446,744,073,709,551,616. Therefore, the iSeries models can address 18,446,744,073,709,551,616 bytes, or 18.4 quintillion bytes. To put this into more meaningful terms, it is twice the number of millimeters in a light year. Light travels at approximately 6,000,000,000,000 miles in one year.

Single-level storage also enables another extremely important iSeries customers benefit,

object persistence

. Object persistence means that the object continues to exist in single-level storage (unless purposely deleted by the customer). Memory access is extremely fast. A customary machine requires that information be stored in a separate file system if the information is to be shared or retained for a long time.

Persistence of objects is extremely important for future support of object-oriented databases for data accessibility and recovery. Objects continue to exist even after their creator goes

iSeries Architecture: Fundamental Strength of the iSeries 15

iSeries Architecture: Fundamental Strength of the iSeries

away. The iSeries models are uniquely positioned to exploit this characteristic of object persistence, where customary systems use a less-elegant mechanism that requires them to store their persistent objects in a separate file system, with all the attendant performance implications.

SOI

The Silicon on Insulator (SOI) technology was applied for the first time for the iSeries with OS/400 V4R5. This technology is used by the iStar processors of the iSeries. The transistors are built within and on top of a thin layer of silicon that is on top of an insulating layer. The insulating layer is fabricated by implanting a thin layer of oxide beneath the primary silicon surface of the wafer.

On-chip Copper-wiring Technology

Pulsar, iStar, and SStar processors use on-chip copper-wiring technology. Pulsar processors integrate IBM CMOS7S technology. iStar and SStar processors integrate IBM CMOS8S technology. Northstar technology used in prior AS/400e processors deploys aluminum for on-chip wiring.

Copper's better conductivity permits thinner wires to be used, which enables the transistors to be packed closer together. This new denser technology permits additional micro architecture methods to improve performance. Denser processor technology also permits more on-chip cache. Keeping multiple levels of high speed cache is enables efficient utilization of the processors.

Hot-plugging

The term “hot-plug PCI” is used by the computing industry for a wide range of purposes. Primarily, hot-plug PCI refers to the technology that allows users to install and remove PCI devices while the computer is running. For iSeries servers, “hot-plug” is known as concurrent maintenance.

A method must be in place to inform the operating system of insertion and removal events. Driven by the demand for the highest possible availability, PCI hot-plugging is available beginning with OS/400 V4R5 on all iSeries 8xx models and some of the 270 models. A brief description of how hot-plugging is implemented on the iSeries follows.

16 iSeries Handbook

iSeries Architecture: Fundamental Strength of the iSeries

Hot-plugging in the iSeries is made possible by power control to individual card slots, so that PCI IOPs or IOAs can be added, removed, or replaced while the system remains active. In most cases, IOA configurations can be changed while other IOAs

Beginning in OS/400 V4R5, the interface for hot-plugging actions uses the Hardware Service Manager in the System Service Tools, or a subset of Dedicated Service Tools (depending on which tool you have started). In limited paging environment, Dedicated Service Tools communicates directly with System Licensed Internal Code (SLIC).

Operating System OS/400

One of the single most dramatic points about the iSeries servers is that the operating system, OS/400, is a single entity. This section describes the meaning of this concept.

Once you buy an iSeries server, you do not have to continue shopping for system software components before it is ready to run your business. All of the software components for a relational database, comprehensive security, communications with a broad range of diverse systems, including Internet capabilities, and many more are already there in the operating system. They are all fully integrated into OS/400. By “fully integrated”, we mean fully tested, too. All components and prerequisites for running business applications in the 2000s work together, and are fully tested together. OS/400 operates as a single entity.

A customary machine does not have this approach to its operating system design. A customary operating system, which does the basic system housekeeping, needs a range of software products added before the environment is ready to support modern business applications. Examples of this are software for the relational database, support for various communications environments, software for security, support for an interactive environment, for multimedia, for availability, recoverability, and so on.

iSeries Architecture: Fundamental Strength of the iSeries 17

iSeries Architecture: Fundamental Strength of the iSeries

On a customary machine, many of these software modules are provided by third parties. A customer has to assure that someone integrates all these modules and performs the tests necessary to verify that they all function together. When one of the software components has a new release, a customer again needs to ensure that component is replaced, plus any other software modules on which it depends. The modules need to be at compatible release levels. Should a software malfunction occur, how do you establish precisely which modules are causing it? Can you be certain that multiple third-party software vendors agree with your diagnosis when you blame their software?

OS/400 does not have any of these problems. To achieve the functionality that is standard in OS/400, a customer would need to integrate typically between 10 and 25 different modules of software. OS/400 is installed with all these capabilities as standard. When software is updated, a new release of OS/400 is made available. OS/400 customers do not have to install individual system software components, nor do they have to check that releases can co-exist.

Object-based

An object is a container. Everything the system uses—user and system data structures—is packaged in one of these containers. The objects are encapsulated, which means that you cannot see inside. Inseparable from an object is the list of valid ways in which that object can be used.

There are two important consequences of an object-based design. The first is that a system built around an object model supports machine independence. This means that technology changes can be made in the environment without affecting application programs. The second consequence is that an object-based design delivers a high level of system integrity and security.

All objects are structured with a common object header and a functional portion dependent on object type. Therefore, on the iSeries servers, instructions work on only what they are supposed to work. Data cannot be treated as executable code (so that the processor tries, for example, to execute someone's shoe size). Executable code cannot be treated as data (by having something written into the middle of it).

Certain instructions apply to all objects, while other instructions work only on specific types of objects. It is not possible to misuse an object, unlike the situation that exists for non-iSeries systems without an object-based approach.

Java

Java is a key application development environment for the iSeries server. AS/400 Developer Kit for Java supports Sun's Java 2. The Java Virtual Machine, which resides below the iSeries Layer, enables fast interpretation and execution of Java code on the iSeries servers. In addition, a type of static compiler is available called a

class transformer

, to generate RISC

18 iSeries Handbook

iSeries Architecture: Fundamental Strength of the iSeries

machine code from Java byte codes. This Java transformer enables the direct execution of Java on the system without the overhead of interpretation.

High-performance Garbage Collection is provided by OS/400 to improve the performance and scalability of Java. An advanced Garbage Collection algorithm allows Java to scale to the large numbers of objects expected when running enterprise applications on the server. Over time, Java is planned to become even more integrated with, and tuned for, OS/400 to meet the requirements of performance and scalability on the server without compromising the cross-platform portability of the rich language.

Other technology included in the AS/400 Developer Kit for Java allows GUI applications to run on the system without modification. This support is called Remote Abstract Windowing Toolkit (AWT). It intercepts GUI requests coming from a Java program and re-routes the requests to an attached workstation running its own Java Virtual Machine (JVM). Server programs with graphical interfaces for configuration or tuning run on the system without modification.

Java objects on the iSeries servers can be full-fledged system objects that allow them to be persistent, shared, secure, backed up, and restored. iSeries server single-level-storage technology permits Java objects to be stored in their object form without the performance and maintenance overhead of two-level-store operating systems.

Java Deployment Tools are aimed at simplifying the deployment, management, and tuning of Java applications on the system. IBM has tested InstallShield's Java Edition product. InstallShield allows Java application developers to create packages that will install natively on the iSeries server. This is the common method used to package and install applications on other platforms, such as Windows NT. InstallShield on the iSeries server makes it easier to port applications to the system that are currently targeted for other platforms. A number of Qshell enhancements and utilities are provided to support zip or unzip of Java packages. To aid in performance analysis and tuning of Java applications on iSeries, support is provided to convert data collected by Performance Explorer into standard formats used by popular Java performance analysis tools such as Javation and Hyperprof.

Java applets and applications that access iSeries and programs and data from client workstations (or a Java-enabled server) can be written using the AS/400 Toolbox for Java. Java classes on the client can be used to access existing iSeries applications and data using low-level APIs. The AS/400 Toolbox for Java can be used on a client to access iSeries servers running OS/400 V3R2, V3R7, or V4R1 and later. The ability to run Java applications on the AS/400e requires OS/400 V4R2 or later and V4R5 on the iSeries. The Toolbox requires Java Virtual Machine (JVM) 1.1.6 or later. At V4R4, the AS/400 Toolbox for Java was enhanced to support the Java Database Connection (JDBC) 2.0 specification. Secure Sockets Layer (SSL) specification enable support for data between the workstation and system to be encrypted and the server authenticated.

iSeries Architecture: Fundamental Strength of the iSeries 19

iSeries Architecture: Fundamental Strength of the iSeries

Java is the environment of choice for programming in today's network computing environment. It allows true portability of applications between platforms without modification or recompilation. The iSeries servers are uniquely positioned to leverage Java as it evolves from its current Web focus to a full commercial application environment. The strengths of the iSeries server will be combined with Java's object-oriented, network computing technology to provide solutions in the new millennium.

See “Java for iSeries (5722-JC1 and 5722-JV1)” on page 602 for more information.

Web Serving

An iSeries server can access a vast network of computers as if they are a single entity. Everyone and everything can access and distribute information, applications, and services provided by the network. For Web serving with the iSeries servers, network computing is supported with HTTP Server for iSeries and HTTP Server Powered by Apache for iSeries.

HTTP servers are the core foundation of technology at the heart of all e-business applications. They handle the communication with the client (typically browsers or XML-rendering devices such as palm pilots) and provide the entry point into server resources. These resources can range from simple HTML and GIF files, to e-business and e-commerce applications, all the way to full-blown business-to-business, collaborative enterprises.

iSeries HTTP support includes the Apache HTTP server. Apache, a freeware HTTP server, is open-source software that implements the industry standard HTTP/1.1 protocol with a focus on being highly configure capable and easily extendable. See “HTTP Server for iSeries (5722-DG1)” on page 506 and “HTTP Server for iSeries (5722-DG1)” on page 506.

OS/400 contains a complete set of base products and features that can be used to create a Web presence. Included are TCP/IP, Java, Virtual Private Networking, Cryptographic Services, Secure Socket Layer, Certificate Management, HTTP Server, Apache Server, and many more. The WebSphere family of products offered by IBM for the iSeries server allows you to build a complete e-business Web Site that is secure, easy to develop and maintain, and scale based on your needs.

See “WebSphere and e-business” on page 567 and “WebSphere Development Studio for iSeries (5722-WDS)” on page 611 for more information.

Lotus Domino

Domino for AS/400 is the leading groupware solution available for the iSeries server. It provides unparalleled capability for iSeries customers to use their business data in collaborative e-business solutions, both within their organizations and with their partners over

20 iSeries Handbook

iSeries Architecture: Fundamental Strength of the iSeries

the Internet. Domino for AS/400 provides a critical foundation as companies begin to move from “information overload” into organizational learning and knowledge management. No competitive product offers the ease of use, low cost of ownership, tight integration, and positioning for the future that Domino for AS/400 delivers. Domino for AS/400 is offered with familiar iSeries and AS/400e terms and conditions for purchase, services, and support. See “Lotus Domino Server for iSeries (5769-LNT)” on page 633.

The iSeries Dedicated Server for Domino is specifically designed to deliver outstanding price performance and value when serving a variety of Lotus Domino workloads on a single server. Because the iSeries 270 and 820 models are used as the base models, the iSeries Dedicated Server for Domino is fully configured with all of the same expandability currently available on the iSeries servers 270 and 820.

Refer to “iSeries Dedicated Server for Domino” on page 135 and “AS/400e Dedicated Server for Domino Positioning” on page 45 for more information.

iSeries Integration with the Windows NT Server

Consolidating Servers Inside an iSeries Server

Currently, most companies deploy PC servers by function or service, with each server dedicated and tuned to an individual application such as file, print, or Web serving.

iSeries Integration with Windows NT Server enables Microsoft Windows NT Server Version

4.0 or Windows 2000 to be installed on the Integrated xSeries Server for iSeries. In this single combination server, customers can run their mission critical business applications on the iSeries solution, while also running Windows NT Server or Windows 2000 for file, print, personal productivity, and other applications. Improved hardware control and availability with reduced maintenance costs and simplified user administration and server operations are possible on a combined server.

iSeries is enhanced with additional Windows server integration facilities. These enhancements enable iSeries to support larger and more complex Windows applications and offer additional tools to help reduce the cost of managing Windows server environments.

Attachment of N-way xSeries Servers – New with V5R1

iSeries supports the attachment of external n-way xSeries servers via the High Speed Link. With the new Integrated xSeries Adapter, selected xSeries servers running a Windows 2000 Server can be used to extend Windows application scalability, while retaining the storage consolidation and systems management advantages of the Integrated xSeries Server.

iSeries Architecture: Fundamental Strength of the iSeries 21

iSeries Architecture: Fundamental Strength of the iSeries

Enhancements for the new Integrated xSeries Server include support for up to 32 servers on selected iSeries models. See “iSeries Integration with Windows Server (Base 5722-SS1 as 5722-WSV)” on page 502.

Benefits of Server Consolidation on the iSeries Server

Server consolidation on the iSeries allows you to:

• Consolidate PC server hardware and operations so you can run up to 32 Windows NT

servers in a single server.

• Increase business recovery protection with high-speed backup of the combined iSeries

server and Windows NT systems.

• Improve server uptime and error recovery using highly reliable iSeries disk drives with

RAID-5 and mirroring options. Use a spare Integrated xSeries Server to replace a failed server without reloading Windows NT.

• Maximize I/O investments by balancing iSeries servers and Windows NT disk

resources from a single pool. Switch user data disks between servers. Share the iSeries tape and CD-ROM drives.

Logical Partitioning (LPAR)

Logical Partitioning enhances the role of the iSeries as a consolidated server. LPAR is of value to customers who need server consolidation, business unit consolidation, mixed production, and a test environment, as well as integrated clusters. With LPAR, companies have both the power and flexibility to address multiple system requirements in a single machine.

LPAR lets you run multiple independent OS/400 instances or partitions (each with its own processors, memory, and disks) in an n-way symmetric multiprocessing AS/400e 6xx, Sxx, or 7xx and uni or n-way on 270 and 8xx models. Address multiple system requirements in a single machine to achieve server consolidation, business unit consolidation, mixed production/test environments, and integrated clusters.

Partitions have different system names and may have a different primary or secondary national language, or they may operate using different time zones. Each partition's system values can be set independently. This flexibility is ideal for banks and other multinational companies to centralize operations in a single location, yet retain the national characteristics of each system. Logical partitions are ideal for companies to run mixed interactive and server workloads on a single iSeries. Logical partitions allow the interactive performance of an iSeries to be flexibly allocated between partitions.

22 iSeries Handbook

iSeries Architecture: Fundamental Strength of the iSeries

With OS/400 V5R1, LPAR is significantly enhanced to allow dynamic movement of processor, memory, and interactive performance between partitions. Up to four OS/400 V5R1 partitions per processor with a maximum of 32 partitions is supported.

Virtual LAN support establishes multiple high speed TCP/IP communication connections between partitions. Additional communication hardware is not required.

Linux is now supported in a logical partition.

You can find more details on LPAR in “Logical Partitions (LPAR)” on page 473.

Virtual LAN

Virtual LAN is new with OS/400 V5R1. Virtual LAN provides 16 independent high speed internal bus-to-bus communication paths between logical partitions and supports TCP/IP protocol.

Virtual LAN provides the additional granularity to set up high speed communications between partitions by being selective on which partitions or applications within a partition are allowed to communicate with other logical partitions on the system. More importantly, it allows high speed bus-to bus communication between OS/400 partitions and Linux partitions. It will be possible to select multiple communications paths between partitions and potentially tie in each of these paths to a specific application.

The enablement and set up of Virtual LAN is easy and does not require an IPL or any special hardware or software. Once a virtual communications port is enabled for a given partition, a communication resource (CMNxx) is created for that partition. The user can then create a high speed 1 GB Ethernet line description over this resource and set up TCP/IP configuration appropriately to start communicating to another partition. A maximum of 16 virtual ports can be enabled for high speed communications per partition.

Virtual LAN does not require any additional software or hardware. It provides the ability to provide multiple communication paths between applications that are executed in each of the partitions.

Extended Adaptive Cache

Extended Adaptive Cache is an advanced read cache technology that improves both the I/O subsystem and system response times by reducing the number of physical I/O requests that are read from disk. Extended Adaptive Cache operates at the disk subsystem controller level. It does not affect the system processor.

iSeries Architecture: Fundamental Strength of the iSeries 23

iSeries Architecture: Fundamental Strength of the iSeries

Management of the cache is performed automatically within the I/O adapter. It is designed to cache data by using a predictive algorithm. The algorithm considers how recently and how frequently the host has accessed a predetermined range of data.

The design of Extended Adaptive Cache is based on specific data management strategies of the iSeries server. To explain, whether the disks are device parity protected, mirrored, or unprotected, the data stored on the disks has a tendency to occur in bands. This means that there are physically contiguous areas of disk storage that fall under one of the following categories:

• Areas where the data is actively read

• Areas of data that are both actively read from and written to

• Areas that are frequently written to

• Areas of storage that are not frequently accessed

The goal is to cache bands characterized as read or write and read-only. A band that is characterized as write-only, while cached in the storage subsystem write cache, remains largely unaffected by Extended Adaptive Cache. Extended Adaptive Cache is designed to not harm the performance of large blocks of data that are either sequentially written or sequentially read. In this case, the pre-fetch capability of the disks, as well as other caches in the system, ensures a quick response time.

Using Extended Adaptive Cache improves the performance of database-read actions and all read actions. This includes read actions that are generated by other system components such as the Integrated xSeries Server. It also works effectively in storage subsystems that have device parity protection or mirroring.

Extended Adaptive Cache Simulator Restrictions and Considerations

• A storage controller capable of supporting Extended Adaptive Cache is required for

Extended Adaptive Cache Simulator. This includes the #2748, #4748, #2778, or #4778.

• The Simulator is enabled and disabled by the user through AS/400 Operations

Navigator, Management Central, or Collection Services.

• Performance Tools LPP is required for Extended Adaptive Cache Simulator.

• Activating the Extended Adaptive Cache Simulator does not actually improve your

system's performance. It gathers statistical information to predict the performance improvement that Extended Adaptive Cache could offer.

• Extended Adaptive Cache Simulator and Extended Adaptive Cache cannot be active

at the same time on the same I/O adapter.

OS/400 Portable Application Solutions Environment

The OS/400 Portable Application Solutions Environment (OS/400 PASE) is a technology designed to expand the iSeries solutions portfolio. OS/400 PASE is an integrated runtime that provides simplified porting of selected solution provider UNIX applications.

The broad base of iSeries server applications are continually enhanced by new applications coming to the platform from a variety of sources. Until recently, the iSeries servers’ Integrated Language Environment (ILE) accounted for the majority of C or C++ applications ports, many originating on UNIX systems. Other applications have UNIX system-specific requirements or are designed for highly compute intensive demands that favor a UNIX runtime. With the latest addition of OS/400 PASE, ISVs can rapidly port UNIX applications to the iSeries and take advantage of the extensive iSeries architecture.

OS/400 PASE provides a broad set of AIX interfaces, in a runtime that allows selected UNIX application binaries to run directly on the PowerPC processor of the iSeries server.

Refer to “PASE (Portable Application Solutions Environment) (5722-SS1 Option 33)” on page 494. You can also find more information on the Web at:

http://www.iseries.ibm.com/developer/factory/pase/index.html

Reliable, Managed Availability

The iSeries server has a reliable history of designing key functions into the hardware and software. High availability is one reason to select a managed availability approach. Other reasons include minimal disruptive backup solutions and the ability to non-disruptively install and pre-test new versions, releases, or software fixes to make optimum use of all company and system resources.

Hallmarks of iSeries availability include redundant internal hardware features, such as RAID-5 and mirroring. The robustness and stability of OS/400 extends into its multiple, subsystem support (batch, interactive, multi-language, applications). The iSeries server offers managed availability to ensure that it is ready to do business when you are.

iSeries managed availability software is also called

cross-system mirroring

• The ability to have one system act as a “hot” backup system to one or more primary

systems. The primary and secondary systems do not have to be the same size or model.

• A rapid switchover to the secondary machine in the event of an emergency.

• System backup that allows data from the primary system to be completely backed up

after only a few minutes of down time. While the secondary system has a “static” copy of the “primary” system’s data, the primary system continues to operate. Changes are

. It provides:

iSeries Architecture: Fundamental Strength of the iSeries 25

iSeries Architecture: Fundamental Strength of the iSeries

transmitted to the secondary system and applied when the backup is complete, therefore, providing continuous protection.

• The secondary system can be used for other activities, for example, business

intelligence or application development, while it concurrently provides backup to the primary system. The secondary system can also be used to “load balance”, to offload work of the primary system.

• Selection of which items on the primary system to dynamically protect by the

secondary system. This can minimize disk capacity on the secondary system or allow a smaller model to be used to “cross-system mirror” the larger system.

• Cross-protection among two or more systems, hundreds of miles apart. Data integrity

is maintained in both directions. Backups can be performed at the remote site.

• New software versions and releases (OS/400 and associated software), or fixes on the

secondary system can be applied while the primary system continues to function. Testing can occur on the secondary system before non-disruptively updating the primary system.

iSeries servers offers superior technology, service, and support in each of five critical components of availability:

• Single system reliability: Architecture and baseline design make the iSeries server one

of the most reliable servers in the world. The iSeries serves the small business customer with minimal skill or resource to manage complex environments. From its inception, the iSeries architecture inherits a design where reliability and availability are equal parameters to features like processor speed, memory capability, and number of disk arms.

iSeries design and development resources enable high levels of availability in a single system environment. This highly reliable design is useful for unplanned outages by the iSeries customer. The single-system iSeries remains the core building block to repeat and extend functions into other areas of the business.

• Single-system availability management: iSeries servers have high-availability

facilities that are fast, automated, and easy to use. Best availability practices are accessible to help reduce the duration of planned and unplanned outages. These high availability practices include facilities such as:

– Save-while-active – Parallel save and restore – Backup Recovery and Media Services (BRMS) for iSeries – RAID-5 disk parity protection – Disk mirroring protection – Automated journal management – Access path protection

26 iSeries Handbook

iSeries Architecture: Fundamental Strength of the iSeries

• Clusters: Cluster technology is implemented to reduce downtime due to planned

outages and site disasters. System availability during planned outages contributes to an increase of unplanned outage coverage.

iSeries clustering took a major step forward with the introduction of Cluster Resource Services (APIs) as part of OS/400 V4R4. OS/400 handles the complexity of managing systems in a cluster and keeps track of data and applications. Simple cluster management is provided with the Simple Cluster Management GUI, which is part of Operations Navigator in V5R1. Advanced cluster management and enhanced data resilience applications are available from cluster middleware business partners to complete the total high availability solution.

Significant new capabilities with V5R1 include Independent Auxiliary Storage Pools (IASPs), which allow access to Integrated File System data that is independent of the System ASP and other User ASPs. Refer to “Clustering” on page 479.

• Applications - ClusterProven: A high availability solution for the iSeries server

involves the active participation of cluster middleware business partners. The partners provide advanced cluster management and data resiliency tools. Solution developers design applications to maintain the state of an application across an outage.

• Availability services and support: As a world leading enterprise computing vendor,

IBM has a collection of products and services to assist the customer to develop and maintain a high availability environment.

Linux for iSeries

IBM supports your choice of platform and operating systems, a commitment now extended to include Linux, the open-source operating system. Linux can enable a new stream of e-business applications to complement the strengths of the iSeries as an integrated core business solution. Linux inherits important strengths and reliability features of the iSeries architecture.

iSeries is enhanced to support Linux running in a secondary logical partition. The primary partition runs OS/400 V5R1. Up to 31 Linux partitions are supported depending on the iSeries model. See “Linux for iSeries” on page 477 for more details.

High Speed Links (HSL)

A new bus structure using High Speed Links (HSL) provides a faster data transportation mechanism for the iSeries 270 and 8xx models. These new systems have faster processors, more on-chip cache, a faster memory bus, a super fast cross-bar switch complex (with speeds

AS/400e to iSeries 400

Clustering with Switchable DASD and IASP

OS/400 V5R1 and HSL OptiConnect provide switchable disk capability. Independent Auxiliary Storage Pools and switched disk clusters provide the ability to access content on a set of disk units from a second system. Support for both planned and unplanned outages is improved when the system currently using a switchable disk experiences an outage. Operations are continued on a system even when an isolated controller or disk unit fails.

Data availability is improved with Independent Auxiliary Storage Pools or switched disk clustering. Within a cluster, users can be switched to an alternate node in the cluster (another iSeries server) upon an outage. Integrated file system data residing in an IASP can be switched to another iSeries server without an IPL. This enables one iSeries to take over data and I/O controller in a disk tower from another iSeries.

Option 41 of OS/400 V5R1 is required to enable independent ASPs and switched disk clusters. It is a chargeable feature.

The primary function in the early stages of clustering is to offer coverage for planned upgrades and maintenance on the production system without affecting users accessing data from the switched disk towers, for the User Defined File System only. Cluster management middleware software, shipped as part of OS/400 option 41, manages the switchover. For high availability purposes, it ensures that no two systems access the disks (data) at the same time.

28 iSeries Handbook

iSeries Architecture: Fundamental Strength of the iSeries

A properly designed switch disk cluster can offer advantages over a data replication cluster. Because a switch disk cluster does not use data replication, there is less overhead on the systems and, therefore, more resource available to process transactions. A switched disk cluster can be simpler to operate. Domino 5.0.7 is the first application to take advantage of this support and uses the switched disk architecture to attain ClusterProven specification. Switched disks do not remove the requirement to have application resiliency. The application is critical to the design of a true continuously available environment.

In this first release of Independent ASP, IFS files only are supported. For V5R1, IFS applications such as Lotus Domino or many Web serving applications are supported. This is useful in situations where workstations or communication lines are associated with the IFS data and the associated application is being switched. Planning and setup work are required to make sure the resources being switched are named identically on both servers.

Note: All I/O, not just the disk in the I/O tower, is switched. Any LAN, WAN, workstation controllers, etc. in the I/O tower are switched at the same time.

Fibre Channel Adapters

With V5R1, the iSeries can attach external disk and tape subsystems via high speed fibre channel disk and tape adapters. This enhances the iSeries’ ability to participate in Storage Area Networks (SAN). Storage Area Networks (SANs) may be defined as a combination of technologies – including hardware, software, and networking components – that provides any-to-any interconnection of server and storage elements. Fibre Channel technology is often used in many of the more flexible topologies and is gaining popularity and usage.

Without other components, a Fibre Channel cable runs directly from an iSeries Fibre Channel adapter to a Fibre Channel adapter in a tape drive or IBM ESS (Shark). The cable can be up to 500 meters long. If more than 500 meters is needed, a pair of hubs or switches is added to the configuration, allowing up to 10,000 meters (10 km) distance. The iSeries supports a specific managed hub. A managed hub is a hybrid, a limited switch, but smarter than a plain, regular hub. The iSeries also supports a regular switch in QuickLoop mode.

Refer to “V5R1 System Unit Hardware (PCI)” on page 292 for information on the Fibre channel adapters. See “Peripherals” on page 399 for information on hubs and switches. You can refer to “Removable Storage Media Devices” on page 353 and “Removable Storage Media Devices” on page 353 for tape drive information.

Database

DB2 UDB for iSeries offers state of the art database functions and open systems, standards based technology, while providing the maturity, stability, and ease of use that has become the trademark of the iSeries server. DB2 Universal Database (UDB) for iSeries is fully integrated into the OS/400 operating system software. It is not a separate product.

DB2/400 has been enhanced over the years to include many new and emerging standards. The integrated database is a full function database with features competitive to other widely used databases. The fact that the DB is integrated allows the operating system to control some of its management functions and makes it easier to maintain than competitive DB from other vendors reducing the need for a dedicated Database Administrator. Its security functions are integrated into the operating system. These functions allow a better security model than other DB where additional tools may need to be purchased to provide these functions.

The SQL Client Integration API allows providers of gateways and client/server solutions to integrate their products with DB2 UDB for iSeries. Many iSeries customers have the need for applications that not only access DB2 UDB for iSeries data, but also access data on other databases platforms such as Oracle or Sybase.

See “DB2 Universal” on page 455.

iSeries Business Intelligence Solutions

What is Business Intelligence?

Business Intelligence (BI) turns corporate data into meaningful business information. It can help you understand business trends and make better forecasting decisions. It can be used to bring better products to market in a more timely manner. It can be used to analyze daily sales information and make snap decisions that can significantly impact your company's performance. Business Intelligence provides a means for you to become familiar with who your customers are.

Business Intelligence turns corporate data into decision support information. Business Intelligence solutions have become much more affordable due to new innovations in software and hardware. One of these key technologies is data warehousing. Data warehouses provide the plumbing for Business Intelligence applications. The advent of data warehouse technology and industry specific Business Intelligence applications have made implementations meaningful and cost effective.

iSeries Enabling Technology

The iSeries servers offer state-of-the-art 64-bit relational database processing. The system has been optimized for a Business Intelligence environment with customized hardware (iSeries servers) and optimized software (DB2/400, SMP for DB2/400, DB2 Multi-System, and Data Propagator Relational). These hardware and software functions combine to make a powerful Business Intelligence server that is easy to install, manage, and use.

With iSeries server open interfaces, hundreds of tools can be used to provide Business Intelligence solutions accessing DB2/400 data transparently. Such tools include desktop analysis tools (Business Objects, for example) and sophisticated multi-dimensional analysis (commonly referred to as OLAP) tools (Essbase/400, for example), with no special programming required.

SMP for DB2/400

provides parallel query processing. This allows multiple processors in a single server to collectively work on a single query, which can improve query performance by as much as 400%.

DB2 Multi-System

support provides clustering for the iSeries and allows up to 32 servers to be “clustered” together into a single system. This clustering provides almost unlimited scalability and unparalleled performance for customers. The combination of all of these advanced features has dramatically improved system performance so much that customers using UNIX systems, PC servers, and even large specialized parallel servers have converted from these machines to iSeries servers.

Data replication is an important technology to facilitate the automated loading of data warehouses while cleaning up or summarizing data for integrity and performance purposes. DataPropagator/400 provides asynchronous data movement between OLTP systems and

iSeries Architecture: Fundamental Strength of the iSeries 31

iSeries Architecture: Fundamental Strength of the iSeries

Business Intelligence systems. Data Propagator allows fields to be summarized, derived, or aggregated into the data elements necessary in your data warehouse.

Data mining is a Business Intelligence application that uses mathematical algorithms to scan potentially large amounts of data to find the golden nuggets of information. Intelligent Miner for AS/400e provides the most advanced data mining application for iSeries customers. It offers optimized computer models to “discover” data relationships previously unknown. The models include algorithms for clustering, information classification, predictions, associations, sequential pattern recognition, and time sequence patterns. This analysis provides executives with insight that can truly be a competitive advantage.

Business Intelligence Solutions

Industry-specific Business Intelligence solutions allow customers to implement off-the-shelf industry applications that are designed for their business. These applications provide a range of functions that are specific to an industry and generally provide users with instant functional application templates that can be customized to meet each businesses unique needs.

Business Intelligence Tools and Applications

Virtually every major Business Intelligence tool is supported on the iSeries servers. That includes such tools as Data Mirror and ETI Extract for moving and cleansing data, and tools for organizing data into a multi-dimensional and relational format as Essbase/400 and DataTracker. It also supports such multi-dimensional analysis tools as Analyzer, Business Objects, and Cognos Powerplay. These tools allow customers unlimited flexibility in building their own Business Intelligence applications. They also allow applications to use OS/400 and non-OS/400 data.

There are many technical advantages of using the iSeries server for your Business Intelligence server. The main reason why customers choose the iSeries server is the combination of its power and simplicity. The system provides a full range of tools, applications, and hardware in a single integrated platform that helps to make rapid implementation a reality. Large and small businesses alike agree that this is the ideal Business Intelligence server.

iSeries servers provide outstanding database technology that supports rapid access to large amounts of data. OS/400 supports a wide range of Business Intelligence solutions including small departmental applications, and very large Business Intelligence environments. The benefits of this application are measured by the more informed decisions that can be made as a result of having better information and information in a format to support the decision-making processes of a company.

e-business

Success in business today depends on one thing: meeting customer needs, which are unique to each organization. To meet those needs, the best option is to build a computer to do business the way each organization does. That means a server that is flexible, versatile, and can deliver customized solutions, all in a cost effective manner.

The iSeries server has always been designed for business. By tightly integrating hardware, software, middleware, and the operating system. The iSeries servers provide a combination of power and flexibility that organizations can rely on to help them in their business. This design also makes it possible for the system to help ensure that they move with technology as it changes.

The latest iSeries hardware enhancements are the iSeries 270 and 8xx models. The newest version of the operating system is OS/400 V5R1. OS/400 is engineered to provide the performance and tools needed to help to obtain a quicker return on a business’ investment in such critical areas as e-business, enterprise resource planning, Business Intelligence, and server consolidation.

e-businesses require hardware and software solutions with cost-effective computing power. However, more importantly, they need solutions that scale well as workloads grow larger and more complex. To scale well means the computer system grows in capacity to accommodate business growth without changing the customer's applications, hardware, or system software investment. The iSeries has always been known for its scalability and meeting the needs of a dozen to several thousand users with the same architecture and operating system. The recent outstanding performance of iSeries as a Domino server in an independent NotesBench audit (10,400 concurrent light mail users on a single iSeries server) demonstrates that the iSeries scales just as well with new, advanced e-business applications as it does with a core line-of-business applications.

Characteristics of a Successful e-business

IBM has effectively branded and marketed the term have a general sense of what e-business means. But an expanded explanation with better examples is necessary. The topics that follow describe the successful e-business:

• Fully exploiting the latest IT tools and techniques

• Delivering a broad spectrum of applications

• Reaching a broad spectrum of users

These defining actions sound familiar to anyone who knows the fundamentals of using information technology (IT) to achieve competitive advantage. e-business does not change the fundamental rules, but represents a dramatic shift in a typical company’s ability to cost-effectively exploit IT on a broad scale. Simply stated, a wide range of affordable tools is

In V5R1, the Information Center installation provides a wizard to install the Information Center to an intranet server from the iSeries. The wizard can even configure your HTTP server and set up search on the intranet.

XML Enablers

eXtensible Markup Language (XML) is one of the key technologies fueling growth of e-business and mobile e-business solutions. XML is becoming the standard way to represent data in a portable, reusable format for use in a number of solutions ranging from business-to-business (B2B) solutions that link together trading partners to pervasive computing applications, which connect mobile devices such as cell phones to core business solutions.

IBM and iSeries are committed to supporting XML. This support is demonstrated by the suite of XML application enablers delivered with OS/400 in V5R1, providing a core of XML services for applications to build on.

The XML application enablers provided in V5R1 include:

• XML parsers for use with Java and C++ applications. XML parsers are a common

building block that XML-based solutions use to work with data in XML format.

• XML parsing interfaces for procedural languages such as RPG, COBOL, and C. These

interfaces open the realm of XML to existing solutions, providing an easy path to extend these solutions with XML support.

• An Extensible Stylesheet Language (XSL) processor used to apply XSL stylesheets to

transform an XML document into another markup language format. XSL stylesheets are the standard way to convert data between two XML document types and are commonly used to convert XML data to HTML for presentation in a Web browser environment.

Security

The many levels of security available with OS/400 ease the job of system security management. The five levels of security range from minimal to an enhanced level that

36 iSeries Handbook

iSeries Architecture: Fundamental Strength of the iSeries

enables the iSeries servers to operate at the C2 level of trust as defined by the United states government. Security at V5R1 has been enhanced with:

• Enhanced system integrity with digital signature and object signing

• Easier to use Digital Certificate Manager

• Enhanced password protection

See “Security” on page 453.

Summary

iSeries servers offer a brilliant architecture that is not found on simply any business computing system. There are many examples of where the system architecture has delivered on its promise of making the most advanced technology readily and continuously available to its customers. For example, the iSeries servers have enabled their customers to:

• Provide Internet access to existing iSeries applications. Through a product known as

HTML Gateway (which resides within OS/400), Internet users can access and run iSeries applications.

• Integrate diverse environments (such as Microsoft Windows NT and Lotus

Notes/Domino) onto the iSeries server. All customer solutions require a range of hardware and software products from a variety of vendors. The iSeries server, through integrating these mixed environments, simplify the task of managing them.

• Change to the on-chip copper-wiring processor technology or to Silicon on Insulator

technology for the medium and high end servers.

• Implement PCI hot-plugging technology for higher availability, and use other

performance boosting innovations such as the High Speed Link and new high speed LAN adapters.

Commercial Processing Workload

When the AS/400 system was announced in 1988, the Relative Performance Rating (RPR) or Relative System Performance (RSP) of different models was measured using a RAMP-C workload. This workload is representative of general commercial processing. RPR figures for AS/400 models have been expressed relative to the 9404 Model B10, which was the initial entry model for the AS/400 range in 1988. It had a RPR rating of 1.0.

iSeries

The AS/400e product line continues to grow in power with the PowerPC RISC processors and 24- and 12-way processors. With the increased processing power and more applications using vital technologies, such as Web serving, client/server, and multimedia, the point was reached when RAMP-C was no longer a valid means for measuring relative performance. Therefore, RAMP-C was replaced by a workload measurement called Commercial Processing Workload (CPW) in the second half of 1996.

Relative performance measurements are derived from commercial processing workload on the AS/400e. CPW is representative of commercial applications, particularly those that do significant database processing in conjunction with journaling and commitment control.

CPW contains a number of advantages over RAMP-C for measuring the iSeries and AS/400e servers, such as:

• Inclusion of a batch component

• Increased numbers of transaction types

• Support for journaling and commitment control

• Increased path lengths

• More complex file and terminal I/O

These enhancements mean that CPW exercises hardware and software paths that more closely match the paths exercised by our customers' current installations.

Workload and Performance

CPW values have been calculated for all previous AS/400e models. The summary table for most of the models, shown in “Summary of Earlier AS/400, AS/400e, and iSeries Models” on page 745, includes the CPW figures as well as RAMP-C figures. For processors announced since August 1997, CPW values are issued. No further RAMP-C figures are provided.

Note: Throughout this document, both RAMP-C and CPW performance figures are described

as Relative System Performance (RSP). This is done to ensure consistency and to identify what is being referred to. RAMP-C or CPW is used to identify to which RSP the figures apply.

CPW figures are not based relative to a single model, as was the case with RAMP-C. CPW values give a relative performance rating of all iSeries and AS/400e processors.

CPW can be used as a quick means of comparing performance. However, a more detailed analysis should always be done using BEST/1 for OS/400. The performance users see that their AS/400 depends on many factors. Some of these factors include: the type and number of disk devices, the number of workstation controllers, the amount of memory, the system model and processor, the application being run, and other factors.

IBM Workload Estimator for AS/400

The IBM Workload Estimator for AS/400 is a Web-based estimation tool that automates the manual calculations previously required from paper sizers. The Estimator tool allows the user the option to enter data for multiple workloads, from which a machine recommendation is made that best fits overall system needs.

Disk Arm Requirements

The disk configuration can be a major contributor of performance bottlenecks. It is important to size an iSeries and AS/400e server with an appropriate number of disk arms, to provide for the best obtainable disk subsystem performance, and, therefore, improve overall system performance.

A physical disk drive (and the processing through the disk controller) performs a specific number of disk accesses each second. Newer disk arms and controllers provide better performance than previous drives. Therefore, fewer disk drives (disk arms/actuators) can typically be used, yet provide comparable performance.

42 iSeries Handbook

Workload and Performance

To help size the minimum number of disk arms required for a given AS/400e processor, refer to the AS/400 Disk Arm Requirements based on the

ISV and other application solution providers also have recommendations for a minimum configuration.

iSeries Model 270 and 8xx Performance

The iSeries Model 270 and 8xx servers are significant steps in the evolution of the AS/400e server product line. iSeries Models 270, 820, 830, and 840 are configured to meet a wide range of performance requirements. Whether the system is running mostly back-office applications, newer e-business applications, or a mixture of both, the performance can be customized on the new servers to match business needs. Each model includes a base processor and interactive performance feature. Optional processor and interactive performance features can be selected to balance the server's performance for a given workload. Increasing performance on installed servers is done simply and with little disruption.

Note: Please note the following terms:

Processor Feature: Used to indicate the feature code by which the processor is

•

ordered.

Interactive Feature: The feature code by which interactive performance is ordered.

•

Processor Feature Code: Used by OS/400.

•

System Processor Feature: Used by SLIC to indicate the same function.

•

iSeries Models 270, 820, 830, and 840 offer two CPW ratings to allow customizing of performance for a given workload:

Processor CPW: Represents maximum relative performance running commercial

•

processing workloads for a processor feature. Use this value to compare relative performance between various processor features. Processor CPW is known as Client/Server CPW in prior releases.

Interactive CPW: Represents the relative performance available to perform interactive

•

workloads. The amount of Interactive CPW consumed reduces the available Processor CPW by the same amount. Interactive CPW for a specific processor is changed through the installation of optional Interactive Features.

The interaction of the Processor CPW and Interactive CPW is illustrated in the following figure.

Workload and Performance 43

Workload and Performance

This chart shows the CPW that is available for server workloads as the interactive workload increases. On the left side of the chart, the scale runs from 0 to 100%, which represents the amount of Processor CPW available for server workloads (non 5250-type workload). On the right side of the chart, a similar scale reflects the amount of Interactive CPW used by Interactive workloads (5250 based). Each of the dotted lines dissecting the rectangle represents various levels of Interactive CPW that can be purchased when ordering an interactive feature for 270 and 8xx servers. Interactive features are not available on the Model

250.

At any point, the amount of CPW used to perform interactive workloads reduces the CPW available for server workloads by an equal and proportionate amount. For example, for a system with a processor CPW of 810 and an interactive feature CPW of 240, it is possible to use up to 240 CPW for an interactive workload and still have 570 CPW available for the non-interactive workload. On the other hand, if none of the AS/400e is used for interactive workloads, all of the Processor CPW is available to perform server workloads. No tuning or management is required.

For best performance, all critical system resources should be kept in balance with proper configuration. This includes processors (quantity and speed), number of disk arms, amount of memory, balanced HSL usage and more. For example, high I/O requirements on Optical HSL may be better handled by copper HSL.

Capacity Upgrade on Demand (CUoD)

iSeries Capacity Upgrade on Demand offers the ability to non-disruptively activate one or more additional central processors of specific models of iSeries Models 830 and 840. CUoD adds capacity in increments of one processor, up to the maximum number of On Demand processors built into the Model 840. CUoD has significant value for installations for customers who want to upgrade without disruption.

44 iSeries Handbook

Workload and Performance

There are now six Capacity Upgrade on Demand processor features (#2416, #2417, #2419, #2352, #2353, and #2354) for the Model 840 and one CUoD processor feature (#2351) for the Model 830. Each offers a number of are in “active” status and a set of

On Demand processors (one or more) can be permanently activated by ordering the desired quantity of feature code #1604 for Models 840 or #1605 for the Model 830 as an MES order. Ordering feature #1604 and #1605 generates a CUoD Activation Code, which is then posted on a Web site and mailed to the customer. This activation code must then be entered at the server console.

Planning Guide for Capacity Upgrade On

AS/400e Dedicated Server for Domino Positioning

AS/400e capabilities to support Lotus Domino are firmly established since the announcement of Lotus Domino for AS/400 in January 1998. In mid-1999, IBM and Lotus delivered a first in the industry—the AS/400e Dedicated Server for Domino. Two models and six processor features were added in 2000.

For entry Domino environments, the Dedicated Server adds scalability for disk and memory capacity. For larger Domino environments, enterprise-class scalability and capacity can be achieved. The iSeries and AS/400e server’s reliability, robust subsystem architecture, and ease of operations provide a sound base to develop and deploy rich Web development and serving functions of Domino solutions. Combined with the rock-solid reliability and scalability of iSeries or AS/400e servers, Domino customers can achieve highly effective Web sites with intranet, extranet, and Internet capabilities.

iSeries and AS/400e customers extend their traditional applications and data by adding Lotus Domino solutions to their existing servers, as part of upgrades, or as stand-alone servers for e-mail, groupware applications, and Web sites. Domino customers use Domino partitioning on iSeries or AS/400e servers to consolidate Domino workloads onto one server with a simple, single footprint to deliver e-mail and business applications. Server consolidation offers vertical growth within the processor. Growth is available within the model.

With the availability of Dedicated Servers for Domino, customers choose to deploy Domino solutions on separate servers from other business applications for several reasons:

• Messaging and e-business servers are mission-critical assets. Reliability,

maintenance, and availability requirements differ from other production systems.

• Many organizations employ specialized staff and servers to deliver messaging and

groupware to their businesses, separate from those that support their line-of-business applications.

Workload and Performance 45

Workload and Performance

• Some organizations have remote environments, which require onsite groupware

servers to provide key applications and e-mail to their users.

The price/performance and the increased scalability of the Dedicated Servers enhance the cost advantage for customers who need a mixed workload Domino server. The Dedicated Server for Domino is positioned to compete strongly for Domino placements compared to multiple Intel-based servers.

Consider Dedicated Server for Domino for:

• New Lotus Domino solutions on a manageable, reliable, and scalable server.

• Reliability and manageability to support mission-critical Domino applications.

• Consolidation of several servers to a single iSeries or AS/400e servers by employing

the partitioning function of the Lotus Domino Enterprise Server license, multiple Domino servers for e-mail, Domino applications, Web serving, or a combination on segregated Intel servers.

• Groupware applications and messaging with existing system operations and skills.

• Standalone intranet, extranet, or Internet servers using Lotus Domino.

• Reliable servers to support Domino in remote locations where administration staff is

not available.

The iSeries Dedicated Server for Domino Model 820 is the ideal model server for customers who require scalability or capacity beyond what the Model 270 Dedicated Domino #2424 processor provides.

Customers who require scalability or capacity beyond what the Dedicated Server for Domino 820 provides should pursue iSeries Models 830 or 840 servers, or to deploy multiple servers for their Domino applications.

Upgradability: Processor feature conversions are supported within each Dedicated

Releases supported: Support is offered for Lotus Domino Release 5.01 or later. The

•

AS/400e Dedicated Server for Domino does not support Domino 4.6 or earlier.

The iSeries Dedicated Server for Domino is priced to be most competitive in these situations:

• Versus multiple single-function Intel Domino servers

• When reliability, manageability, and availability are a critical requirement in new or

current Domino implementations

The Dedicated Domino processors are tuned specifically for Lotus Domino workloads. They provide sufficient capacity for non-Domino workloads, such as remote DB2 access, file serving, Integrated xSeries Server for iSeries, and TCP/IP, which support a Domino environment.

Lotus Domino workloads: Defined as out-of-the-box functions such as:

•

– E-mail – Calendars and scheduling – Web serving – Standard Lotus Domino template applications (for example, discussion database,

workflow, and so on) and custom developed applications written with Domino Designer that perform no external program calls, relational database access, or Java integration.

Non-Domino workloads: For customers planning significant use of non-Domino

•

workloads, Dedicated Server for Domino should not be proposed. Instead, consider iSeries Model 270 or 8xx with standard processor features.

Considerations for non-Domino workloads include:

Workload and Performance 47

Workload and Performance

– Any and all workloads not designated as Domino workloads are considered to be

non-Domino workloads. They should be managed to a maximum of 10 to 15% of the

CPU. – Stand-alone Java, RPG, COBOL, or C applications are non-Domino workloads. – Applications can work alongside Domino on the same AS/400e. An example is a

Domino server that uses the *MSF SMTF Services option along with the QMSF task

to process Internet mail through the OS/400 SMTP server. The OS/400 SMTP server

and QMSF task are non-Domino work. – Domino applications using application integration functions, such as DB2 Universal

Database access or external program calls, are considered non-Domino workloads.

System administration: iSeries Dedicated Server for Domino can be effectively

• managed when there is no Interactive CPW (Interactive CPW = 0) available for application workloads. Interactive CPW is an approximate value reflecting the portion of Processor CPW that can be used for workloads performing interactive-based tasks (5250). The zero interactive CPW is intended to support a single interactive job for system administrative functions, that is:

– Any job started from a console (green screen) to perform system administration

only

functions is not considered interactive work if it is the

interactive job running

(single interactive job exception). – Any system administration job submitted to batch is not considered interactive work. – Any use of Operations Navigator (GUI administration functions) is not considered

interactive work.

Interactive workloads: Any task started through a 5250 session (5250 device or 5250

• emulation) where the user waits for a response is considered to be interactive work.

– Application processing that uses 5250 interfaces is not supported on the iSeries

Dedicated Server for Domino.

– 5250 print is not supported on the iSeries Dedicated Server for Domino.

Relative performance measurements are derived by performing various monitored and measured workloads on iSeries and AS/400e servers. The results can be used to compare relative performance characteristics of processor features offered for servers.

Simple Mail Users (SMU): This relative performance measurement is derived by

• performing high-volume Lotus Domino mail workloads on Dedicated Domino processors. SMUs are representative of mail applications, particularly those that do not perform any database related tasks. SMUs represent the estimated number of concurrent light mail users for the Dedicated Domino processors. Reported values reflect 70% processor utilization.

48 iSeries Handbook

Workload and Performance

• Mail and Calendaring Users (MCU): This relative performance measurement is derived by performing mail and calendaring functions. This workload is considerably more complex than Simple Mail Users. The MCU workload represents users on a Notes client who are reading, updating, or deleting documents in an e-mail database, as well as lookups in the Domino directory and scheduling appointments and invitations. Reported values reflect 70% processor utilization.

Commercial Processing Workloads (CPW): CPWs are representative of commercial

• applications, particularly those that do significant database processing in conjunction with journaling and commitment control. The reported values for CPW represent the capacity of a non-Domino workload available to support a Domino environment. The reported CPW may be used by System Resource activities and Domino resource extensions such as database accesses and external program calls. The amount of CPW consumed reduces the available capacity to perform Domino workloads reflected as SMU or MCU.

– Processor CPW is an approximate value reflecting the maximum amount of

non-Domino workload (10 to 15% of CPU) that can be supported.

– Interactive CPW is an approximate value reflecting the portion of Processor CPW that

can be used for application workloads performing interactive-based tasks.

Dedicated Domino Processors

Domino resources

The above figure shows the relationships of the various workloads on the Dedicated Domino Processors. Domino can take any available CPU capacity (even below the line). The CPW workload can never rise above the line, and excessive attempts to use CPW resources do not significantly affect Domino performance. If CPW exceeds its limit, the system will not redirect Domino resources to non-Domino (CPW) work, and the non-Domino performance degradation can be dramatic.

For some Domino solution scenarios, you need to work closely with an IBM, Lotus, or IBM Business Partner representative to determine whether iSeries Model 270 with standard processor features, 8xx servers, or the new Dedicated Server for Domino is most appropriate for the proposed environment. In particular, Domino applications that require some degree of

integration with DB2 Universal Database for AS/400 data or use some external program calls (for example, RPG programs or Java) require careful evaluation.

The resources of Dedicated Server for Domino are focused primarily on the Domino workloads (see the following figure). Their ability to deliver superior Domino price/performance depends on running a workload very close to “pure Domino”. A small percentage of the overall processor capacity (10 to 15%) can be used for non-Domino work, such as routine system administration tasks and non-Domino programs invoked by the Domino application.

Large user community

In evaluating Domino applications that access non-Domino functions, such as DB2/400 integration or program calls, ensure that the non-Domino functions represent a low percentage of the overall system utilization. Once non-Domino work reaches a maximum CPU capability on the Dedicated Server for Domino, no additional processing power will be available for non-Domino workloads. If the proposed Domino application employs any significant DB2 UDB or program integration, a standard iSeries or AS/400e server model is a better choice.

5250 Throughput

The iSeries and AS/400e servers support a family of displays and emulation adapters that are known as the 5250. The supported data stream is known as a 5250 data stream. Throughput considerations for these workstations regard the flow of the character stream, as discussed in the following section.

5250 Express Data Stream

The #2720, #2722, #2746, #4746, and #6180 twinax workstation adapter cards have three major features that can increase throughput:

50 iSeries Handbook

Workload and Performance

• 2X Mode: 2 Mbps versus 1 Mbps throughput of the #6050 workstation controller.

Optimized Mode: The block transfer of data is improved to almost double the

• throughput to or from the attached device.

•

Dual Mode: Means that two ports are polled simultaneously on the #2722, #2746,

#4746, and #6180 workstation controllers. On older controllers (such as the #6050 workstation controller), only one port out of eight is active at any given time.

The enhancement produces nearly four times the throughput when all of the attached devices on a port support 5250 Express Data Stream. All of the IBM devices from the original 5251 up through the 3489 support the Express Data Stream.

Refer to Informational APAR II11804 for additional details regarding workstation considerations when attached devices or cabling do not support 5250 Express Data Stream. Additional information on 5250 Express Data Stream is available on the Web at:

http://www.networking.ibm.com/525/

The IBM 7299 twinax-to-fiber multiplexer fully supports all the new functions of the #2720, #2722, #2746, #4746, and #6180 workstation controllers.

The CPA Toolkit runtime environment is supported for V4R5. Software developers and customers are encouraged to migrate CPA applications to kernel threads, the strategic OS/400 function. Information on migrating from CPA to kernel threads is available at:

http://www.as400.ibm.com/developer/threads/cpa/roadmap.doc.html

• Altered Program Objects: Some application providers and customers alter their program objects. Today you cannot recreate a program object without source code on an iSeries or AS/400 server if observable information, which includes program creation data, has been removed. A future enhancement to OS/400 will retain program creation data when observable information is removed, allowing the program to be recreated at the customer's option. Recreating a program helps ensure its integrity and allows you to take advantage of new hardware or enhancements in translator technology. However, when a program is recreated, alterations made to the program object are not retained. Programs that depend on alterations may fail or behave in an unexpected manner should the customer choose to recreate them. Customers should consult their application providers regarding potential impacts of program re-creation.

Note: IBM recommends against altering program objects because altered programs may

bypass checks made by OS/400 that help ensure system integrity and security.

iSeries Direction 57

iSeries Direction

Statement of Direction

Statements of direction identify the commitment of IBM to direct the iSeries servers toward a given design or technology. Understanding them can provide insight into IBM’s design and technology plans.

As part of the iSeries announcements made in April 2001, IBM announced a commitment to the following direction:

Database File support in independent auxiliary storage pool/switchable disk In a future release, IBM intends to enhance OS/400 support for switching the ownership

of objects between Primary and Secondary Servers through the use of Independent Auxiliary Storage Pool (IASP) and switchable disk technologies by extending the list of possible switched objects beyond Integrated File System (IFS) files. Additions would include objects associated with the DB2 Universal Database for iSeries and other OS/400 library based objects.

Planning Information

Business grows, the information systems needs of a business change, and technology changes to allow more efficient and cost effective methods to solve business problems. As the iSeries and OS/400 are enhanced, new technology is introduced. Other technology reaches a point where no further enhancements, functions, or maintenance is planned. This section helps our customers plan for these changes and to protect their investment as their business needs change.

• AS/400 Models 4xx and 5xx: OS/400 V5R1 is the final release to be supported on

AS/400 Models 400, 436, 40S, 500, 510, 530, 50S, and 53S.

•

Client Access Family: IBM intends to remove support of the Windows 95 operating

system for the Client Access Express for Windows client. Client Access Express for Windows 95 will not be supported beyond V5R1.

This removal of Windows 95 support applies to all of the functions shipped with Client Access Express, including EZ-Setup, Operations Navigator, Management Central, and Operations Console. Client Access Express for Windows will continue to be supported on the Windows 98, NT 4.0, ME, and 2000 Operating systems.

•

AS/400 support for Windows Network Neighborhood: IBM intends to remove the

support of the Windows 95 operating system from AS/400 NetServer. Windows 95 will continue to be supported from AS/400 NetServer in V5R1, but not in subsequent releases. AS/400 NetServer will continue to support the Windows 98, NT 4.0, ME, and 2000 Operating systems.

¼-Inch Cartridge Tape: V5R1 is the final release to support the #6385/#6485 ¼-inch

Cartridge Tape Unit. Customers using these tape units can order a conversion to a 16 GB ¼-inch Cartridge Tape Unit (#4483/#4583/#6383/#6483), a 25 Gb ¼-inch Cartridge Tape Unit (#4486/#4586/#6386/#6486), or a 50 GB ¼-inch Cartridge Tape Unit (#4487/#4587). Customers who use their tape drive primarily for incremental fast backups and need smaller (2.5 GB) capacity tape drive units should consider the #4482/#6382 2 GB ¼-inch tape drive.

Software End of Support Dates

With the high quality and reliability of the current OS/400 software releases, OS/400 users may not recognize the importance of periodic upgrading to stay on a supported release. Every release of OS/400 has a defined Program Services period, with the end date announced with the initial announcement of the release. After the end of that Program Services period, IBM no longer accepts problems for defect analysis.

Communications (WAN) Functions No Longer Supported

The following functions are no longer supported on current iSeries and AS/400e product line WAN hardware (such as the #2609 EIA 232/V.24 Two Line Adapter, the #2610 X.21 Two Line Adapter, and other, older adapters). They are not supported on the #2720 PCI WAN/Twinaxial IOA, the #2721 or #2745 PCI Two-Line WAN IOA, the #2699 Two-Line WAN IOA, or the #9771 Base PCI 2-Line WAN with Modem.

• X.21 switched interface (X.21 leased support)

• X.21 Shorthold mode

• V.25 2 port autocall. This is the protocol used to auto dial on switched connections using modems that require a second port dedicated to the dial function. Do not confuse this with V.25bis, which is the current day autocall protocol that sends dial commands over the same port used for data. V.25 bis itself is supported.

• Asynchronous communication speeds of less than 300 bps.

• Data Rate Select signal on the EIA 232/V.24 interface. This function is used by some, older 2400 bps modems to reduce the speed to 1200 bps.

• LPDA-1 (Link Problem Determination Aids). This is a diagnostic function supported by some (primarily older IBM) modems.

• V.54 local and remote loopback (diagnostic functions supported by some modems).

The type and number of disk devices, the number of workstation controllers, the amount of memory, the system model, other factors, and the application running determine what performance is achievable. With the introduction of the Dedicated Servers for Domino, Simple Mail Users is added as a performance measurement.

running CPW in a client/server environment. Processor capacity is achievable when the commercial workload is not constrained by main storage and DASD. Interactive Performance represents the relative performance available to perform host-centric workloads. The amount of interactive capacity consumed reduces the available processor capacity by the same amount. On the Dedicated Servers for Domino, the Processor CPW is an approximate value reflecting the maximum amount of non-Domino workload (10 to 15% of CPU) that can be supported.
