Compaq ProLiant 5000

The Compaq ProLiant 5000 is the first in a new generation of the Compaq

ProLiant family of high performance servers. The ProLiant 5000 includes

new features and design to achieve performance advantages and use unique

characteristics of Intel Pentium Pro processors and PCI bus architecture.

The ProLiant 5000 server design includes the following new features:

■ Support for the Intel Pentium Pro processors and the Intel 82450GX

chip set.

❏ 166 MHz processors, each with 16KB Level 1 cache and an

integrated 512KB Level 2 cache.

❏ 200 MHz processors, each with an integrated 16KB Level 1

cache and an integrated 256KB Level 2 cache.

■ Optimization for enhanced PCI performance.

■ Support for dual-peer PCI buses.

❏ Primary PCI Bus

❏ Secondary PCI Bus

■ Supports a bridged EISA bus off the primary PCI bus.

■ Support for DIMM memory technology.

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Optimizing PCI and EISA Devices

Compaq has conducted extensive testing to determine optimal

configurations for achieving high performance and ease of use at the initial

installation of a ProLiant 5000 system. These test include integrating the

ProLiant 5000 with network operating system software, such as Windows

NT Server, and installing additional peripherals when the need arises.

This section contains Compaq recommendations for configuring the

ProLiant 5000 server to achieve optimal Windows NT Server performance.

The dual-peer PCI buses capabilities of the ProLiant 5000 server provide

high-bandwidth I/O with two buses operating simultaneously. Dual-peer PCI

buses provide an aggregate bandwidth of 267 MB/s. The I/O board has two

Pentium Pro-to-PCI bridge controllers. The controllers connect the primary

and secondary PCI buses to the host bus. The primary and secondary buses

each have assigned functions.

The configuration recommendations presented in this document focus on:

■ Primary and secondary PCI bus configurations

■ Bridged controllers and the implications of adding additional bridged

controllers

Primary PCI Bus

■ Supports dedicated PCI slots 5-8.

■ Supports the EISA bridged bus.

❏ Supports up to three EISA slots (one dedicated, two shared

EISA/PCI).

❏ Supports integrated EISA peripherals (video, timers,

keyboard, mouse).

Secondary PCI Bus

■ Supports PCI on shared slots 2 and 3 and dedicated slot 4.

■ Supports the Integrated 32-Bit Fast-Wide SCSI-2 controller.

4Configuring the Compaq ProLiant 5000 for Microsoft Windows NT Environments

What is a Bridge?

A PCI bridge connects two independent PCI computer buses together and

allows the buses to communicate with each other. By creating hierarchical

PCI buses, the PCI bridge overcomes the electrical loading limits of the PCI

bus.

PCI Bus Numbering

PCI buses are assigned PCI bus numbers beginning with Bus # 0 for the

primary PCI bus (Slots 5-8) and Bus # 1 for the secondary PCI bus (Slots 2-

4).

PCI bus numbering changes depending on how many PCI bridged

controllers are installed (ex: SMART-2/P Controller) and whether they are

installed in the primary or secondary PCI bus, and slot order of each bus.

For example, in the default factory configuration (Table 1), the SMART-2/P

controller is installed in the primary PCI bus (Slot 5), the SMART-2/P is a

PCI bridged controller causing the bus numbering to change. As stated

previously, the default bus numbers for the ProLiant 5000 without any

bridged PCI controllers installed is Bus # 0 for the primary PCI bus and Bus

# 1 for the secondary PCI bus; adding the SMART-2/P controller to the

primary PCI Bus causes the bus numbers to change to Bus # 0 for the

primary PCI bus, Bus # 1 for the SMART-2/P bridged PCI bus, and Bus # 2

for the secondary PCI bus.

Compaq tested the installation and configuration of bridged PCI controllers

and recommends that the configuration tables (Tables 1-6) be utilized to

minimize the possibility of changing the bus numbers and causing device

drivers such as the NETFLX3.SYS to fail when loading. The failure is due to

the initial bus number used while configuring the PCI NetFlex-3 controller

and adding a bridged controller that changes the bus number of the PCI bus

that the NetFlex-3 controller is installed in. Windows NT does not update

the network interface card configuration which causes any network interface

card to fail during device driver initialization.

Any time additional bridged PCI controllers are added or removed from the

primary bus of an existing configuration, the secondary PCI bus number

changes requiring the network interface controllers to be reconfigured

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Following the recommended configuration tables minimizes the possibility

of this occurring and having to reconfigure the NetFlex-3 controller and also

gives the best performance configuration by dividing the bus load.

Factory Configuration

Table 1 describes the factory configuration with one Netelligent 10/100 TX

PCI UTP network interface controller (NIC) installed in the secondary PCI

bus (Slots 2-4) and one SMART-2 SCSI Controller installed in the primary

PCI bus (Slots 5-8).

In Table 6, by adding the SMART-2/P controller to the primary PCI bus

(Slot 7), the PCI bus number of the secondary PCI bus changes causing the

NETFLX3.SYS device driver to fail while attempting to load.

The following steps highlight the process to correct the issue:

■ Double-click the Network icon from the Control Panel, record

pertinent information on the network adapters (IP address, etc.)

■ Close the Network Settings dialog box.

■ Double-click the Compaq Net icon to launch the Compaq Advanced

Network Control Utility from the Control Panel.

❏ Highlight the failing adapter and select the Uninstall option.

❏ Highlight the adapter again and select the Install option.

■ Close the Compaq Advanced Network Control Utility dialog box.

■ Enter the information (IP address, etc.) recorded earlier on the

network interface card being reinstalled in the Network Settings

dialog box..

■ Shutdown and reboot the server.

NOTE: Any time additional bridged PCI controllers are added or removed from the

primary bus of an existing configuration, the secondary PCI bus number changes,

requiring the network interface controllers to be reconfigured.

NOTE: All Compaq device drivers are available on the Compaq Software Support

Diskette (SSD) v1.18 or later, refer the NTREADME.HLP file included on the

SSD for installation instructions.

Hardware Abstraction Layer Multiprocessor

Support

This section provides an overview of the Hardware Abstraction Layer

support for the Compaq ProLiant 5000. The Compaq ProLiant 5000 is a

Multiprocessor Specification-based server and takes advantage of additional

capabilities provided by Intel MPS capable processors. The HAL is a layer

of software that interacts directly with the computers hardware and is one of

the modular components that make up the Windows NT operating system.

The Microsoft Multiprocessor HAL (HALMPS.DLL) included with

Windows NT will function on the Compaq ProLiant 5000 server and

provides basic HAL functionality
