    Title

    RISC System/6000 7024 Model E20 Server

    Abstract


    The IBM RISC System/6000 Model E20 is a workgroup server which is well suited for customers requiring distributed computing and interoperability. It can be used as a stand-alone multi-user server, workgroup server or data base server and has the connectivity to participate in most currently installed UNIX(1) and PC networks. The Model E20 is designed to allow for system growth in memory, disk, and media devices as needs grow.

    The 7024-E20 is a powerful and expandable server designed to combine the following attributes:

    The result is an affordably priced entry server which supports the broad range of applications currently available to the RS/6000 family of servers running under the AIX Version 4.1.4(R) operating system.

    The E20 uses a modular processor card design implementing a PowerPC 604 processor running at 100 MHz. The modular design allows for an upgrade to future, faster processors following the PowerPC roadmap.

    The E20 integrates key reliability and availability attributes previously only available on higher priced commercial servers such as:

    The I/O expansion buses supported are the industry standard, high performance PCI bus in addition to the traditional Industry Standard Architecture (ISA) bus. Adapters being offered have all undergone thorough testing to verify system compatibility.

    The E20 is packaged in an 8x8 (8 I/O slot, 8 disk/media bay) floor standing tower which is attractive, compact, and quiet. The system is designed for easy installation by users. The E20 is shipped with the ordered internal adapters and devices already configured and installed, and the software can be pre-installed if desired.

    All of this provides a computer platform of exceptional value capable of handling demanding applications today as well as tomorrow.

    The IBM RISC System/6000 Model E20 system features the popular Peripheral Component Interface (PCI) bus technology but also supports Industry Standard Architecture (ISA) and Small Computer System Interface (SCSI) technology.

    Compatible with AIX Version 4.1 Applications

    Customers with applications currently installed on RISC System/6000 processors can enjoy binary compatibility by installing AIX Version 4.1.4 on their IBM RISC System/6000 Model E20 systems. This provides the ability to further distribute applications on low-cost servers without having to maintain different operating systems and applications. This permits efficient, rapid exportation to multiple remote sites requiring the power of a server.

    PowerPC Growth Path

    The IBM RISC System/6000 Model E20 system exploits the power of the PowerPC 604 microprocessor operating at 100MHz and incorporates a synchronous 512KB Level 2 (L2) cache to further increase performance. As the PowerPC family of microprocessors evolves, the IBM RISC System/6000 Model E20 is designed to be upgradable to additional performance levels.

    Reliability Availability and Serviceability (RAS)

    IBM continues to apply RAS experience to the RISC System/6000 servers from many decades of building mission critical mainframe computers. RAS characteristics such as error detection, fault tolerance, reliable hardware components, high availability, fault management, concurrent or on-line diagnostics, which were initially available only on mainframe computers, are now implemented on RISC System/6000 servers.

    RAS is an integral part of the RISC System/6000 and AIX Version 4 design philosophy. It starts with the development of the architecture and flows through the design, development, and manufacturing process. But RAS doesn't stop there, it affects the way that IBM can offer service on RISC System/6000 products to keep systems operational.

    Product Positioning

    The IBM RISC System/6000 (TM) Model E20 is a low priced, high performing, commercial deskside server. By combining AIX 4.1.4 reliability and functionality with industry standard bus architectures, the E20 offers exceptional value for multi-user applications. At 8 slots and 8 bays, the E20 is the entry server model in the RISC System/6000 server product line.

    The E20 is a 100 MHz PowerPC 604 commercial server with a 512KB L2 cache and up to 512MB of memory. In can be configured with 5 PCI slots, 2 ISA slots and 1 PCI or ISA slot, as well as 8 storage bays. The E20 offers more performance, more slots, more media bays, and larger L2 cache than the 43P as well as offering server RAS characteristics such as ECC memory. The E20 should be the server of choice for the Model 43P clients. In addition, the E20 offers superior price performance to the C10 and C20 servers, when micro channel support is not required and when PCI and ISA capability is needed. It may also offer better price performance than the 370, 380 and 390 servers when floating point is not required.

    Micro Channel(TM) models of the RISC System/6000 family are appropriate when specific device support is required, when higher performance is required, when applications only available on AIX Version 3.2.5 are required, or if specific features such as floating point are required.

    Hardware Requirements

    Either an ASCII terminal with attachment cable or a graphics display with attachment cable and graphics adapter is required for initial set up and must be available locally for service. If an ASCII terminal is uesd, it must be attached through serial port S1.

    If a graphics adapter is installed console messages (IPL progress/error information/system management information) will be directed to the graphics adapter. The system does not detect if a display is attached to the adapter. The user may attach any supported device to either serial port.

    If a graphics adapter is not installed console messages (IPL progress/error information/system management information) will be directed to serial port S1. The system does not detect if an ASCII display is attached to serial port S1, use of any device other than an ASCII display on serial port S1 will result in lost messages and unpredictable results on that device.

    Boot Devices

    The system may be booted from CD-ROM, internal or external hard disk, or network booted using Ethernet (Feature 2985 or 2987) or Token Ring (Feature 2979) adapters.

    Software Requirements

    AIX Version 4.1.4 or later ordered separately.

    AIX Version 4.1.4 is offered for Servers and for Clients. Some I/O and functions are only supported with AIX 4.1.4 for Servers.

    The X.25 adapter requires AIXLINK X.25 (5696-926) LPP ordered separately.

    Limitations

    AIX Version 4.1.4 Limitations

    There are some functions of AIX Version 4.1.4 that are hardware dependent. The following limitation applies on IBM RISC System/6000 Model E20.

    Compatibility

    SCSI Limitations

    Tape Limitations

    The 4GB/8GB 4MM internal tape drive (Feature 6142) may be mounted in bay number 8 only. This insures adequate air flow required for proper operation. A second tape drive may be installed in bay 6 if bay number 7 remains empty. Mounting in other bays may cause over heating and lead to data errors.

    There can be a maximum of one graphics adapter installed on the system.

    Disk Limitations

    Only disk drives with a one inch height are supported for internal use. Disk drives with a 1.6 inch height are not supported. Installation of any 1.6 inch high drives may result in overheating of the system.

    Installation of the AIX operating system is limited to the following methods: installation by manufacturing with the initial order, CDROM with the AIX installation CD, or via a restore tape made with the AIX command 'mksysb' and a supported 4mm tape drive.

    E20 systems shipped before March 31, 1996, may require a chargeable hardware upgrade in order to operate Windows NT 3.51 (PowerPC Edition). See RPQ 8A1027 for details.
