Summary of Contents for Compaq 112726-001 - ProLiant - 6500

  • Page 1 Intel’s 32-bit Pentium® II Xeon™ processor, as well as ECG Technology Communications improvements to the ProLiant 7000’s PCI bus architecture. Compaq has fulfilled its promise to extend the functionality of the ProLiant 7000 by providing an upgrade path to four or eight Pentium II Xeon processors.
  • Page 2 BUSINESS INFORMATION), EVEN IF COMPAQ HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. The limited warranties for Compaq products are exclusively set forth in the documentation accompanying such products. Nothing herein should be construed as constituting a further or additional warranty.
  • Page 3 N T R O D U C T I O N In today’s business environment, customers require powerful servers with fault-tolerant features to keep their businesses running 24 hours a day, 7 days a week. The Compaq ProLiant 7000 Server provides breakthrough high-performance and high-availability technologies that keep the server up and running in the most demanding 7x24 environments.
  • Page 4 ECHNOLOGY RIEF (cont.) Larger Cache Sizes The Pentium II Xeon processor supports larger L2 caches than previous Intel processors. Pentium II Xeon processors are initially available in 512-KB and 1-MB configurations with future plans for a 2-MB cache. In contrast, the Pentium Pro processor has a maximum 1-MB cache. The larger data cache provides a significant performance boost, especially in symmetric multiprocessing (SMP) configurations and systems used in memory-intensive applications, such as on-line transaction processing.
  • Page 5 (cont.) Pentium II Xeon Performance Compaq tested performance of Pentium II Xeon processors in the ProLiant 7000 server using two industry-standard benchmarks: the TPC-C benchmark test and the TPC-D version 1.3.1 benchmark test. The TPC-C benchmark measures performance in an on-line transaction...
  • Page 6 (cont.) Thermal Design Compaq has designed an innovative thermal cooling solution for the Pentium II Xeon processor that contributes to increased system reliability and future performance scalability to 8-way architectures. Heat pipes transfer heat away from the Slot 2 cartridge thermal plate to cooling fins mounted atop the cartridge (Figure 1).

  • Page 8 64-bit adapters work in the 32-bit expansion slots. In addition, the two extended PCI slots allow the Smart Array 3100ES Controller to route three SCSI buses to the I/O For more information on Compaq’s memory technology, see technology brief Memory Technology Evolution, document number 518A/0697.
  • Page 9 ECHNOLOGY RIEF (cont.) board (slot 10/11 SCSI ports 1, 2, and 3) where the buses are cabled to the three internal drive cages. This eliminates cabling between the controller and I/O board. Slots 5 and 6 on PCI Bus 2 are shared with an embedded dual-channel SCSI controller (SCSI ports 2 and 3).
  • Page 10 (cont.) Standard Peripheral Board The Standard Peripheral Board (Figure 5) contains ASICs (among them four Compaq-designed ASICs) to provide connections for all system management and legacy components. This includes connectors for the mouse, keyboard, IDE CD-ROM, diskette drive, video, parallel devices, SCSI devices, and Integrated Management Display (IMD).

  • Page 11: Redundant Hot-Plug Fans

    Thus, the end-user can have continuous service and the administrator can greatly reduce both planned and unplanned downtime. Note: Software that supports a redundant NIC configuration is available on the Compaq Support Software CD that ships with the server.
  • Page 12 If the internal air temperature exceeds the second trip point, the OS initiates a controlled shutdown of the server. Simultaneously, a warning message is sent to the IMD and Compaq Insight Manager. The server restarts automatically when it has cooled sufficiently.

  • Page 13: Redundant Hot-Plug Power Supplies

    2.0 V and the voltage for the cache is 2.5 V. Compaq PPMs are programmable and support all current and future versions of Slot 2 processors. Each PPM module has redundant circuitry. If a failure occurs in one circuit of the module, the other circuit automatically takes over the task of regulating power to the processor.
  • Page 14 ECHNOLOGY RIEF (cont.) The microcontroller performs the following functions: Self-test - The intelligent power supplies perform their own power-on self-test that checks temperature, RAM integrity, ROM version, analog-to-digital conversion accuracy, and non- volatile memory integrity of the power supply. Auto Line Sensing - Because the power supplies are rated for both 750W (at 220V) and 500W (at 110V), a line-sensing feature automatically recognizes which line voltage is connected.
  • Page 15 Graceful Shut Down - A 10-second delay counter begins as a message warning of an imminent power-down goes to Compaq Insight Manager and the IMD. Because of the communication between the microcontroller and the OS, the OS can delay the power down until all running applications have properly closed.

  • Page 16: Hot-Plug Hard Disk Drives

    When a power supply is hot swapped, the microcontroller governs the power-up and power-down sequences, enables the health drivers to calculate redundancy “on the fly,” and informs the health drivers of changes in load. Compaq hot-plug power supplies are readily identifiable by their port- colored bezel, as shown in Figure 11.

  • Page 17: Pci Hot Plug Technology For Pci Adapters

    Compaq’s implementation of PCI Hot Plug differs from implementations by other vendors whereby several slots are powered down at once or an entire PCI bus is powered down. Compaq incorporated electronics into the server to control each PCI Hot Plug slot individually, so that a single slot can be powered down without affecting the operation of the other slots.

  • Page 18: Management Technologies

    Alternatively, these same operations can be performed by using the PCI Hot Plug software application. Mechanical Design Compaq designed the ProLiant 7000 system chassis for safe and easy installation and removal of PCI adapters. The ProLiant 7000 has nine PCI Hot Plug slots—five 64-bit slots and four 32-bit slots.

  • Page 19: Integrated Management Display

    The administrator has the ability to access the server, perform diagnostics, reset the system, watch the reset process remotely, and view reset sequences, regardless of whether the OS is functional. For more information about IRC, refer to the Compaq technology brief Remote Server Management with Integrated Remote Console, document number 582A/1096.
  • Page 20 ECHNOLOGY RIEF (cont.) same as the current configurations, the system will boot normally. The OS selection may be changed during subsequent reboots. E R VI C E A B I L I T Y E A T U R E S By providing easy access to server components, the ProLiant 7000 design further reduces the downtime associated with upgrades and field maintenance.

  • Page 21: Power Supplies

    MHz bus it supports create more power and thermal load than the current Pentium Pro-based systems. In planning for the Pentium II Xeon processor and 4-way requirements, Compaq engineered the ProLiant 7000 power supplies and chassis with “headroom” to accommodate this additional load.

  • Page 22: Chassis Design

    SEC cartridge and its associated heat sink are larger than the Pentium Pro PGA and require significantly more room in the chassis. When designing the ProLiant 7000 chassis, Compaq included enough room to accommodate the new Pentium II SEC cartridge form factor and up to eight processors.
  • Page 23 Figure 16: I/O panel inserts can be replaced to upgrade server. O N C L U S I O N As business requirements become more demanding, Compaq will continue to deliver servers that meet those requirements and that can be expanded to meet future needs as well. The ProLiant 7000 offers many hot-plug and redundant technologies that allow virtually continuous uptime for all key server components.
