Product Description
The Compaq ProLiant DL760 is a high-density data center server with 8-way scalable
performance intended for use in 24x7 multiserver rack environments. The server is based on the
ProFusion 8-Way architecture and is packaged in a dense, 7U form factor design.
Performance is maximized with up to 8 Pentium III Xeon processors and 16GB of ECC SDRAM
memory. Eight 64-bit PCI-X slots, three 64-bit PCI slots an integrated Smart Array Controller
and Ultra3 hard drives, enhance input/output performance.
The Compaq ProLiant DL760 has the following standard high availability features:
 PCI Hot Plug slots
 Redundant hot pluggable power supplies and fans
 Redundant processor power modules and network interface controllers
 Smart Array 4200 controllers
 Error checking and correcting (ECC) memory
 Disk System Tracking and Disk Drive Fault Tolerance
 Automatic Server Recovery (ASR2).
In addition to a new Intel Pentium III Xeon 900 MHz processor, the ProLiant DL760 ships
standard with PCI-X technology and ROM-Based-Setup-Utility (RBSU).
New Models
Three new server models are shown in the following table. The number of processors, size of
cache, memory capacity and processor speed vary according to model. The following features are
common to each model:
 Pentium III Xeon processors
 ECC protected 100MHz SDRAM DIMM memory
 PCI and PCI-X I/O busses
 Integrated Smart Array controller
NOTE: The integrated Smart Array controller is implemented using RAID on a Chip (ROC)
which is physically embedded in the system I/O board. A small jumper board called the Array
Enabler routes the ROC signals to the hard drives. This board can be replaced with a bypass cable
assembly (Integrated Array Bypass) to allow an optional controller such as the Compaq 4200
Array Controller to run the internal drives.
Processors Speed Cache Memory Part Number
2 700MHz 1MB 1GB 177656-xx1
4 700MHz 2MB 2GB 177657-xx1

New Features
PCI-X technology leverages the wide acceptance of the PCI bus and provides an evolutionary
I/O upgrade to conventional PCI. PCI-X technology increases bus capacity to more than eight
times the conventional PCI bus bandwidth — from 133 MB/s with the 32-bit, 33-MHz PCI bus to
1066 MB/s with the 64-bit, 133-MHz PCI-X bus.
PCI-X enhances the PCI protocol to develop an industry-standard interconnect that exceeds a raw
bandwidth of 1 gigabyte per second (GB/s) and will meet upcoming bandwidth needs of
enterprise computing systems.
PCI-X provides backward compatibility with the PCI bus at both the expansion board and system
level.
ROM–Based Setup Utility (RBSU) will automatically configure the system based on the
operating system selected. RBSU supports a wide range of customizable configuration features.
RBSU replaces the System Configuration Utility feature.
Faster Intel Pentium III Xeon processors are supported on the ProLiant DL760 server. The
server is capable of supporting up to eight processors and eight Processor Power Modules. Each
processor requires an associated Processor Power Module. Each Processor Power Module has
two identical power circuits on it to provide redundancy for its processor. A ninth Processor
Power Module is always present to provide processor bus termination power.
NOTE: The server will NOT boot if the Intel Pentium III Xeon processors are NOT the same
speed.
Understanding PCI-X
PCI-X is an evolutionary bus architecture based on the prevalent PCI bus. PCI-X technology
leverages the wide acceptance of the PCI bus and provides an evolutionary I/O upgrade to
conventional PCI.
PCI-X technology increases bus capacity to more than eight times the conventional PCI bus
bandwidth — from 133 MB/s with the 32-bit, 33-MHz PCI bus to1066 MB/s (1GB/s) with the
64-bit, 133-MHz PCI-X bus as summarized in the table below:
PCI-X Bus Performance
64-bit card 133 MHz 1066 MB/s
The 64-bit, 133-MHz interconnect protocol achieves this performance through the use of a
register-to-register design that allows higher clock frequencies and new protocol enhancements
such as the attribute phase and split transactions that allow more efficient use of the bus.
PCI-X technology is backward compatible with conventional PCI systems at the system, device
driver, and the adapter level. Conventional PCI adapters will operate in PCI-X systems, and vice
versa; however, when a PCI-X adapter is placed on a conventional PCI bus, it is limited to
conventional PCI speeds.

Compaq ProLiant DL760 5

Rev.1.21 Page 5 of 12
A PCI-X system automatically switches between conventional PCI and PCI-X mode, depending
on the type of adapters installed on the bus segment. If a PCI-X bus segment includes any
conventional PCI adapters, that segment must operate in conventional PCI mode.
Just as with conventional PCI, the operating frequency is adjusted to match that of the slowest
device on the bus. If the bus includes a 33-MHz adapter, the bus must operate at 33 MHz. If only
conventional 66-MHz devices are present, a PCI bus optionally operates in conventional 66-MHz
or 33-MHz mode. The table below illustrates several possible combinations of system and adapter
frequencies:
Understanding RBSU
RBSU is an updateable, "intelligent" configuration utility that is embedded in the server ROM.
The purpose of RBSU is to help you configure certain server hardware settings and prepare your
server for operating system (OS) installation. Like its predecessor, SCU, RBSU allows you to
view and establish server configuration settings during initial system startup, as well as modify
them after the server has been configured.
The Configuration Options table describes some of the configuration options that may be
available through RBSU.
Option Description
System Select or configure system specific options such as OS,
COM ports, LPT ports, standard boot order, NUMLock
PCI devices View installed PCI devices and configure IRQs for
these devices.
Date and time View and change system date and time
Automatic Server Recovery (ASR) View and configure ASR settings
Server passwords Set and change server passwords
System identification Set the server asset tag and text displayed on the IMD
Boot controller order View and change the controller order. All mass storage
devices are included in this selection.
Advanced options Configure options normally set by default and not user-
modified, such as MPS/APIC mode, Hot-Plug
Reservation, and CPU correction marking.

Key Features
The features that make RBSU an efficient and flexible configuration tool include:
•Familiar Interface. RBSU retains the look, feel, and functionality of SCU to ease
transition for customers accustomed to using SCU. Only a few menu and navigation
differences are noticeable.
•Flexible User Control. RBSU allows you to select between a default configuration or
create your own, customized configuration settings.
•ROM-Embedded Location. Because it is housed in the system ROM, RBSU can be
accessed by pressing the F9 function key during the system startup process. This feature
allows you to change your settings without having to depend on a SmartStart and Support
Software CD or startup diskette.
•"Silent" Conflict Resolution. Rather than allow configuration conflicts to occur, RBSU
automatically avoids any settings that would create hardware and software conflicts.
RBSU checks each setting as it is made and immediately resolves possible conflicts
without issuing an audible warning message.
•Virtual Presence. Because RBSU is embedded in the system ROM, system administrators
can use the Compaq Remote Insight Lights-Out Edition to remotely access and configure
the system in a totally unattended fashion. (When these tools are used in combination
with the SmartStart Scripting Toolkit, multiserver configurations can also be performed
remotely in a silent command line mode.)
NOTE: A reboot is required to enable the Remote Insight Board to access the ROM.
•Automated Language Selection. RBSU is available in English, French, Italian, German,
Spanish, or Japanese. RBSU allows you to change your language selection at any time
and it automatically updates the keyboard mappings to match the standard keyboard for
the language you select.
•Machine-Specific Settings. RBSU is customized to each server, based on the unique
hardware and software environment of the server. Because RBSU contains only the
information relevant to a single machine, it is smaller and runs faster than traditional
configuration utilities.
•Replication Support. RBSU is designed to work with ConRep to create an editable script
file containing the configuration settings of the server. This script file can then be
deployed across multiple servers with similar hardware and software components.
•System Restore Capability. RBSU uses the Compaq Intelligent Manageability tools to
backup system settings to a configuration file. These settings can be saved for a quick
system restore in a server recovery situation.
•Easy to Update. You can quickly install the latest version of RBSU on an already
configured server by flashing the system ROM using the latest version of ROMPaq.
•Does Not Require or Use the System Partition. RBSU can be installed as part of the
configuration process onto the system partition, if desired. However, unlike SCU, RBSU
does not automatically create the system partition – SmartStart will create the system
partition if it finds no data on the disk.
For more information, see the ROM Based Setup Utility User Guide at www.compaq.com.

Service Considerations
New I/O Module PCI/PCI-X Slot Information
I/O Board Slot Descriptions
The new I/O module has 11 slots divided into 3 buses. The Primary bus (slots 7 through 9) is
keyed (1) for 64-bit 5V PCI boards or 64-bit PCI universal boards.
The Secondary bus (slots 1 through 6) and the Tertiary bus (slots 10 through 11) are keyed (2) for
64-bit 3.3V PCI/PCI-X boards or 64-bit universal PCI/PCI-X boards.
This is a change from the previous I/O module, where the Secondary bus (slots 1 through 6)
supported 64-bit 5V PCI boards.
I/O Expansion Board Descriptions
The Primary bus will accept a 64-bit 5-V PCI board (1) or a 64-bit universal PCI board (3).The
Secondary and Tertiary buses will accept a 64-bit 3.3-V PCI/PCI-X board (2) or a 64-bit

PCI Hot-Plug I/O Expansion Boards
The ProLiant DL760 server supports PCI Hot Plug. PCI Hot Plug and the server’s operating
system work together to allow the following hot-plug actions:
•Hot replacement of expansion boards–This feature allows you to replace a failed
expansion board with an identical expansion board without powering down the server.
• Hot addition of expansion boards–This feature allows you to install new PCI/PCI-X
expansion boards in previously empty slots without powering down the server under
some operating systems.
• Hot upgrade of expansion boards–This feature allows you to replace an expansion
board with a different expansion board without powering down the server.
PCI Hot Plug is backward compatible, although system components fit into one of two
categories; hot-plug aware or non-hot-plug aware. The following three components are required
in the server for complete PCI Hot Plug capability:
• PCI Hot Plug system hardware (available in this server)
• Operating system with PCI Hot Plug support (currently Microsoft Windows 2000,
Microsoft Windows NT, Novell NetWare, and SCO UNIX – support level varies)
• PCI Hot Plug device drivers (available from operating system vendors, Compaq
SmartStart CD, and some individual hardware vendors)
IMPORTANT: If any of the three required components are not hot-plug aware, the system is
fully functional, but not PCI Hot Plug-capable. For further information about PCI Hot Plug
consult the ProLiant DL760 Servers User Guide First Edition (March 2001) Part Number
173774-001
IMPORTANT: Hot addition is not supported under Windows NT 4.0. Empty slots are powered
up at boot and opening the slot release lever will cause the slot to be powered off. If you add a
board in this manner, you will not be able to power up the slot. Windows NT 4.0 does, however,
support hot replacement of identical I/O expansion boards. See the Compaq QuickSpecs for the
Compaq ProLiant DL760 servers at www.compaq.com for a list of supported I/O expansion
boards.
