Detailed Server Description 15

The server has the following dimensions:

• Depth: Defined by cable management constraints to fit into a standard 36-inch deep rack:

25.5 inches from front rack column to PCI connector surface

26.7 inches from front rack column to core I/O card connector surface

30 inches overall package dimension, including 2.7 inches protruding in front of the front
rack columns

• Width: 17.5 inches, constrained by EIA standard 19-inch racks

• Height: 17 U (29.55 inches), constrained by package density

The mass storage section located in the front enables access to removable media drives without
removal of the bezel. The mass storage bay accommodatestwo 5.25-inchremovable media drives
and up to four 3.5-inch hard disk drives. The front panel display, containing LEDs and the system
power switch, is located directly above the hard drive media bays.

Below the mass storage section and behind a removable bezel are two PCI-X power supplies.
Each PCI-X power supply powers both I/O partitions. Two PCI-X power supplies offer a N+1
configuration.

Enclosed with protective finger guards are nine front online replace (OLR) fan modules.

The bulk power supply is partitioned by a sealed metallic enclosure located in the bottom of the
server. This enclosure houses the N+1 fully redundant bulk power supplies. Install these power
supplies from the front of the server after removing the front bezel. The power supply is 2.45 X

5.625 X 20.0 inches.

16 HP Integrity rx8640 and HP 9000 rp8440 Server Overview

The PCI card bulkhead connectors are located at the rear top.

The PCI X OLR fan modules are located in front of the PCI cards. They are housed in plastic
carriers.

The 12 rear OLR fans attached outside the chassis house 120-mm exhaust fans.

The cell boards are located on the right side of the server behind a removable side cover. For
rack mounted servers on slides, the rack front door requires removal if it is hinged on the right
side of the rack. Removal will allow unrestricted access to server sides after sliding server out
for service..

The two redundant core I/O cards are positioned vertically end-to-end at the rear of the chassis.

Redundant line cords attach to the AC power receptacles at the bottom rear. Two 20-amp cords
are required to power the server. Two additional line cords provide redundancy.

Access the system backplane by removing the left side cover. The system backplane hinges from
the lower edge and is anchored at the top with a single large jack screw assembly.

The SCSI ribbon cable assembly also routes across and fastens to the backside of the system
backplane near the connectors that attach the core I/O boards.

The blue deployment handles hinge outward for manual lift. When server is slide mounted, they
retract against chassis to enable slide action without obstruction.

Front Panel

Front Panel Indicators and Controls

The front panel, located on the front of the server, includes the power switch. Refer to Figure 1-5.

Enclosure Status LEDs

The following status LEDs are on the front panel:

• Locate LED (blue)

• Power LED (tricolor)

• Management processor (MP) status LED (tricolor)

• Cell 0, 1, 2, 3 status (tricolor) LEDs

Figure 1-5 Front Panel LEDs and Power Switch

Cell Board

The cell board, illustrated in Figure 1-6, contains the processors, main memory, and the CC
application specific integrated circuit (ASIC) which interfaces the processors and memory with
the I/O. The CC is the heart of the cell board, providing a crossbar connection that enables
communication with other cell boards in the system. It connects to the processor dependent
hardware (PDH) and microcontroller hardware. Each cell board holds up to four processor
modules and 16 memory DIMMs. One to four cell boards can be installed in the server. A cell
board can be selectively powered off for adding processors, memory or maintenance of the cell
board, without affecting cells in other configured partitions.

Detailed Server Description 17

Figure 1-6 Cell Board

The server has a 48 V distributed power system and receives the 48 V power from the system
backplane board. The cell board contains DC-to-DC converters to generate the required voltage
rails. The DC-to-DC converters on the cell board do not provide N+1 redundancy.

The cell board contains the following major buses:

• Front side buses (FSB) for each of the four processors

• Four memory buses (one going to each memory quad)

• Incoming and outgoing I/O bus that goes off board to an SBA chip

• Incoming andoutgoing crossbar busses that communicate tothe crossbar chips on the system
backplane

• PDH bus that goes to the PDH and microcontroller circuitry

All of these buses come together at the CC chip.

Because of space limitations on the cell board, the PDH and microcontroller circuitry reside on
a riser board that plugs at a right angle into the cell board. The cell board also includes clock
circuits, test circuits, and decoupling capacitors.

PDH Riser Board

The server PDH riser board is a small card that plugs into the cell board at a right angle. The
PDH riser interface contains the following components:

• Microprocessor memory interface microcircuit

• Hardware including the processor dependant code (PDH) flash memory

• Manageability microcontroller with associated circuitry

The PDH obtains cell board configuration information from cell board signals and from the cell
board local power module (LPM).

18 HP Integrity rx8640 and HP 9000 rp8440 Server Overview

Central Processor Units

The cell board can hold up to four CPU modules. Each CPU module can contain up to two CPU
cores on a single die. Modules are populated in increments of one. On a cell board, the processor
modules must be the same family, type, and clock frequencies. Mixing of different processors
on a cell or a partition is not supported. See Table 1-1 for the load order that must be maintained
when adding processor modules to the cell board. See Figure 1-7 for the locations on the cell
board for installing processor modules.

NOTE: Unlike previous HP cell based systems, the server cell board does not require that a
termination module be installed at the end of an unused FSB. System firmware is allowed to
disable an unused FSB in the CC. This enables both sockets of the unused bus to remain
unpopulated.

Memory Subsystem

Figure 1-8 shows a simplified view of the memory subsystem. It consists of four independent

access paths, each path having its own address bus, control bus, data bus, and DIMMs . Address
and control signals are fanned out through register ports to the synchronous dynamic random
access memory (SDRAM) on the DIMMs.

Detailed Server Description 19

The memory subsystem comprises four independent quadrants. Each quadrant has its own
memory data bus connected from the cell controller to the two buffers for the memory quadrant.
Each quadrant also has two memory control buses: one for each buffer.

DIMMs

The memory DIMMs used by the server are custom designed by HP. Each DIMM contains DDR-II
SDRAM memory that operates at 533 MT/s. Industry standard modules do not support the high
availability and shared memory features of the server. Therefore, industry standard DIMM
modules are not supported.

The server supports DIMMs with densities of 1, 2, 4, and 8 GB. Table 1-2 lists each supported
DIMM size, the resulting total server capacity, and the memory component density. Each DIMM
is connected to two buffer chips on the cell board.

20 HP Integrity rx8640 and HP 9000 rp8440 Server Overview

Valid Memory Configurations

The first cell must have one DIMM pair loaded in slots 0A/0B. The server can support as little
as 2 GB of main memory using two 1 GB DIMMs installed on one of the cell boards and as much
as 512 GB by filling all 16 DIMM slots on all four cell boards with 8 GB DIMMs.

The following rules explain the memory configuration:

1. DIMMs must be loaded in pairs (same size within a pair).

2. DIMM pairs must be loaded in slot order (0A/0B, 1A/1B, 2A/2B, ...)

3. Largest DIMMs must be loaded first followed by progressively smaller DIMM module sizes.

A paired set of DIMMs is called a rank. DIMMs in a rank must be of the same capacity. See

Table 1-3 and Figure 1-9for DIMM load order and layout on the cell board.

A quad is a grouping of four DIMMs (Figure 1-9). Configurations with 8 or 16 DIMM slots loaded
are recommended. Adding a rank enables a dedicated DDR-II bus on a cell to increase the amount
of usable memory bandwidth available. Available memory is proportional to the amount of
memory installed.

Cells and nPartitions

An nPartition comprises one or more cells working as a single system. Any I/O chassis that is
attached to a cell belonging to an nPartition is also assigned to the nPartition. Each I/O chassis
has PCI card slots, I/O cards, attached devices, and a core I/O card assigned to the I/O chassis.

On the server, each nPartition has its own dedicated portion of the server hardware which can
run a single instance of the operating system. Each nPartition can boot, reboot, and operate
independently of any other nPartitions and hardware within the same server complex.

The server complex includes all hardware within an nPartition server: all cabinets, cells, I/O
chassis, I/O devices and racks, management and interconnecting hardware, power supplies, and
fans.

A server complex can contain one or more nPartitions, enabling the hardware to function as a
single system or as multiple systems.

NOTE: Partition configuration information is available on the Web at:

http://docs.hp.com.

Refer to HP System Partitions Guide: Administration for nPartitions for details.

Internal Disk Devices

Figure 1-10 (page 22) shows the top internal disk drives connect to cell 0 through the core I/O

for cell 0, in a server cabinet. The bottom internal disk drives connect to cell 1 through the core
I/O for cell 1.

The upper removable media drive connects to cell 0 through the core I/O card for cell 0 and the

System Backplane

The system backplane board contains the following components:

• Two crossbar chips (XBC)

• Clock generation logic

• Preset generation logic

• Power regulators

• Two local bus adapter (LBA) chips that create internal PCI buses for communicating with
the core I/O card.

The backplane also contains connectors for attaching the cell boards, PCI-X backplane, MP core
I/O cards SCSI cables, bulk power, chassis fans, front panel display, intrusion switches, and
external system bus adapters (SBA) link connectors.

Detailed Server Description 23

The two LBA PCI bus controllers on the system backplane create the PCI bus for the core I/O
cards. You must shut down the partition for the core I/O card before removing the card.

Having the SCSI connectors on the system backplane allows replacement of the core I/O card
without having to remove cables in the process.

System Backplane to Cell Board Connectivity

The system backplane provides four sets of connectors, one set for each cell board.

The system backplane routes the signals from the cell boards to the communication crossbars.
Cell boards 0 and 1 are directly connected to the I/O backplane found in the server. Cell boards
2 and 3 can be connected to a separate I/O expansion chassis connected to the system backplane.

System Backplane to Core I/O Card Connectivity

The core I/O cards connect at the rear of the system backplane through two connectors. SCSI and
LAN on a core I/O are accessed via a PCI-X 66 MHz bus. Two LBA bus controllers located on
the system backplane allow communication to the I/O devices. The LBAs are connected to the
SBA on the PCI-X backplane by single ropes.

The system backplane routes the signals to the various components in the system. The core I/O
signals include the SCSI bus for the system hard drives and the bus for the removable media
devices. Each core I/O card provides SCSI buses for the mass storage devices.

The management processor for the chassis resides on the core I/O card, so the system backplane
also provides interfaces required for management of the system. These interfaces and the
manageability circuitry run on standby power.

You can remove the core I/O cards from the system as long as you shut down the partition for
the core I/O card before removing the card. The hot-plug circuitry that enables this feature is
located on the system backplane near the core I/O sockets.

System Backplane to PCI-X Backplane Connectivity

The PCI-X backplane uses two connectors for the SBA link bus and two connectors for the
high-speed data signals and the manageability signals.

SBA link bus signals are routed through the system backplane to the cell controller on each
corresponding cell board.

The high-speed data signals are routed from the SBA chips on the PCI-X backplane to the two
LBA PCI bus controllers on the system backplane.

Clocks and Reset

The system backplane contains reset and clock circuitry that propagates through the whole
system. The system backplane central clocks drive all major chip set clocks. The system central
clock circuitry features redundant, hot-swappable oscillators.

PCI/PCI-X I/O Subsystem

The cell board to the PCI-X board path runs from the CC to the SBA, from the SBA to the ropes,
from the ropes to the LBA, and from the LBA to the PCI slots as shown in Figure 1-12. The CC
on cell board 0 and cell board 1 communicates through an SBA over the SBA link. The SBA link
consists of both an inbound and an outbound link with a peak bandwidth of approximately 11.5
GB/s at 3.2 GT/s. The SBA converts the SBA link protocol into “ropes.” A rope is defined as a
high-speed, point-to-point data bus. The SBA can support up to 16 of these high-speed
bidirectional rope links for a total aggregate bandwidth of approximately 11.5 GB/s.

There are LBA chips on the PCI-X backplane that act as a bus bridge, supporting either one or
two ropes for PCI-X 133 MHz slots and the equivalent bandwidth of four ropes for PCI-X 266
slots. Each LBA acts as a bus bridge, supporting one or two ropes and capable of driving 33 MHz
or 66 MHz for PCI cards. The LBAs can also drive at 66 MHz or 133 MHz for PCI-X mode 1 cards,

24 HP Integrity rx8640 and HP 9000 rp8440 Server Overview

and at 266 MT/s for PCI-X mode 2 cards installed in mode 2 capable slots. When cell board 2 and
cell board 3 are present, the cell boards attach to their own associated SBA and LBA chips on the
PCI-X board in the Server Expansion Unit.

The server supports two internal SBAs. Each SBA provides the control and interfaces for eight
PCI-X slots. The interface is through the rope bus (16 ropes per SBA). For each SBA, the ropes
are divided in the following manner:

• A single rope is routed to support the core I/O boards through LBAs located on the system
backplane.

• A single rope is routed to an LBA on the PCI backplane to support a slot for PCI and PCI-X
cards (slot 8).

• Six ropes are bundled into double ropes to three (3) LBAs. They support slots 1, 2, and 7 for
PCI and PCI-X mode 1 cards.

• Eight fat ropes are bundled into quad ropes to four (4) LBAs. They support slots 3, 4, 5, and
6 for PCI and PCI-X mode 2 cards.

NOTE: PCI-X slots 1-7 are dual rope slots while slot 8 is a single rope slot. A rope is defined as
a high-speed, point-to-point data bus.

Each of the 16 slots is capable of 33 MHz/66 MHz PCI or 66 MHz/133 MHz PCI-X. Four slots in
PCI-X support 266 MHz. All 16 PCI slots are keyed for 3.3 V connectors (accepting both Universal
and 3.3 V cards). The PCI-X backplane does not provide any 5 V slots for the I/O cards. Table 1-8
summarizes the PCI-X slot types.

The PCI-X backplane is physically one board, yet it behaves like two independent partitions.
SBA 0 and its associated LBAs and eight PCI-X slots form one I/O partition. SBA 1 and its
associated LBAs and eight PCI-X slots form the other I/O partition. One I/O partition can be reset
separately from the other I/O partition but cannot be powered down independently.

26 HP Integrity rx8640 and HP 9000 rp8440 Server Overview

IMPORTANT: Always refer to the PCI card's manufacturer for the specific PCI card performance
specifications. PCI, PCI-X mode 1, and PCI-X mode 2 cards are supported at different clock
speeds. Select the appropriate PCI-X I/O slot for best performance.

speed cards into slow speed slots will cause the card to be driven at the slow speed.

2 Slot is driven by a single rope and has a maximum speed of 66 MHz.

PCIe Backplane

The 16–slot (8 PCI and PCI-X; 8 PCI-Express) mixed PCI-X/PCI-Express (“PCIe”) I/O backplane
was introduced for the Dual-Core Intel® Itanium® processor 9100 Series release and is heavily

leveraged from the PCI-X backplane design. Only the differences will be descibed here. See

“PCI/PCI-X I/O Subsystem” (page 24) for common content between the two boards..

The PCI-Express I/O backplane comprises two logically independent I/O circuits (partitions) on
one physical board.

• The I/O chip in cell location zero (0) and its associated four PCI-X ASICs, four PCIe ASICs,
and their respective PCI/PCI-X/PCIe slots form PCI-Express I/O partition 0 plus core I/O.

• The I/O chip in cell location one (1) and its associated four PCI-X ASICs, four PCIe ASICs,
and their respective PCI/PCI-X/PCIe slots form PCI-Express I/O partition 1 plus core I/O.

Detailed Server Description 27

Each PCI/PCI-X slot has a host-to-PCI bridge associated with it, and each PCIe slot has a
host-to-PCIe bridge associated with it. A dual slot hot swap controller chip and related logic is
also associated with each pair of PCI or PCIe slots. The I/O chip on either cell location 0 or 1 is a
primary I/O system interface. Upstream, the I/O chips communicate directly with the cell controller
ASIC on the host cell board via a high bandwidth logical connection known as the HSS link.When
installed in the SEU chassis within a fully configured system, the ASIC on cell location 0 connects
to the cell controller chip on cell board 2, and the ASIC on cell location 1 connects to the cell
controller chip on cell board 3 through external link cables.

Downstream, the ASIC spawns 16 logical 'ropes' that communicate with the core I/O bridge on
the system backplane, PCI interface chips, and PCIe interface chips. Each PCI chip produces a
single 64–bit PCI-X bus supporting a single PCI or PCI-X add-in card. Each PCIe chip produces
a single x8 PCI-Express bus supporting a single PCIe add-in card.

The ropes in each I/O partition are distributed as follows:

• One PCI-X ASIC is connected to each I/O chip with a single rope capable of peak data rates
of 533Mb/s (PCIX-66).

• Three PCI-X ASICs are connected to each I/O chip with dual ropes capable of peak data
rates of 1.06Gb/s (PCIX-133).

• Four PCIe ASICs are connected to each I/O chip with dual fat ropes capable of peak data
rates of 2.12Gb/s (PCIe x8).

In addition, each I/O chip provides an external single rope connection for the core I/O.

Each PCI-Express slot on the PCIe I/O board is controlled by its own ASIC and is also
independently supported by its own half of the dual hot swap controller. All PCIe slots are
designed to be compliant with PCIe Rev.1.0. The PCI-Express I/O backplane will provide slot
support for VAUX3.3, SMB*, and JTAG.

PCIe Slot Boot Paths

PCIe slot boot paths are directly leveraged from the PCI-X backplane. See Table 1-6 (page 25)
and Table 1-7 (page 25) for more details.

28 HP Integrity rx8640 and HP 9000 rp8440 Server Overview

NOTE: The differences between the PCI X backplane and the PCIe backplane are as follows:

• Twelve ropes are bundled in two rope pairs to 6 LBAs to support 6 slots for PCI and PCI-X
cards instead of 14. These ropes are capable of 133MHz.

• Sixteen ropes are bundled into dual fat ropes to 8 LBAs to support 8 additional slots for
PCIe cards. These ropes are capable of 266MHz.

1 Each slot will auto select the proper speed for the card installed up to the maximum speed for the slot. Placing high

speed cards into slow speed slots will cause the card to be driven at the slow speed.

2 Slot is driven by a single rope and has a maximum speed of 66 MHz.

Core I/O Card

Up to two core I/O cards can be plugged into the server. Two core I/O cards enable two I/O
partitions to exist in the server. The server can have up to two partitions. When a Server Expansion
Unit with two core I/O cards is attached to the server, two additional partitions can be configured.

A core I/O card can be replaced with standby power applied. The system power to the core I/O
is handled in the hardware the same way a hot-plug PCI/PCI-X card is handled. Standby power
to core I/O is handled by power manager devices to limit inrush current during insertion.

Detailed Server Description 29

Core I/O Boot Paths

The servers internal I/O devices are located on the core I/O. The following table outlines the paths
assigned to the hard disk and removable media disk bays located on the front of the server
chassis. Core I/O card 0 refers to the core I/O located in the upper slot at the rear of the system.
Core I/O card 1 refers to the core I/O located in the lower slot at the rear of the system. Core I/O

Electrical Specifications

This section provides electrical specifications for the HP Integrity rx8640 and the HP 9000 rp8440
servers. These servers share common specifications. The exceptions are separate system power
as well as power dissipation and cooling requirements. The associated data can be found in (xrefs
here).

Grounding

The site building shall provide a safety ground and protective earth for each AC service entrance
to all cabinets.

34 System Specifications

Install a protective earthing (PE) conductor that is identical in size, insulation material, and
thickness to the branch-circuit supply conductors. The PE conductor must be green with yellow
stripes. The earthing conductor described is to be connected from the unit to the building
installation earth or if supplied by a separately derived system, at the supply transformer or
motor-generator set grounding point.

Circuit Breaker

The Marked Electrical for the server is 15 amps per line cord. The recommended circuit breaker

Environmental Specifications

This section provides the environmental, power dissipation, noise emission, and air flow
specifications for the server.

Temperature and Humidity

The cabinet is actively cooled using forced convection in a Class C1-modified environment. The
recommended humidity level for Class C1 is 40 to 55% relative humidity (RH).

Operating Environment

The system is designed to run continuously and meet reliability goals in an ambient temperature
of 5° C–32° C at sea level. The maximum allowable temperature is derated 1° C per 1,000 feet of
elevation above 3,000 feet above sea level up to 25° C at 10,000 feet. For optimum reliability and
performance, the recommended operating range is 20° C to 25° C. This meets or exceeds the
requirements for Class 2 in the corporate and ASHRAE standard. See Table 2-9 (page 37) for an
example of the ASHRAE thermal report.

Typical configuration

Environmental Temperature Sensor

To ensure that the system is operating within the published limits, the ambient operating
temperature is measured using a sensor placed on the server backplane. Data from the sensor is
used to control the fan speed and to initiate system overtemp shutdown.

Non-Operating Environment

The system is designed to withstand ambient temperatures between -40° C to 70° C under
non-operating conditions.

Cooling

Internal Chassis Cooling

The cabinet incorporates front-to-back airflow across the system backplane. Nine 120-mm fans
mounted externally on the front chassis wall behind the cosmetic front bezel push air into the
unit. Twelve 120-mm fans housed in cosmetic plastic fan carriers and mounted externally to the
rear chassis wall pull air through the unit.

Each fan is controlled by a smart fan control board embedded in the fan module plastic housing.
The smart fan control board receives fan control input from the system fan controller on the
system backplane and returns fan status information to the system fan controller. The smart fan
control board also controls the power and the pulse width modulated control signal to the fan
and monitors the speed indicator back from the fan. The fan status LED is driven by the smart
fan control board.

Bulk Power Supply Cooling

Cooling for the bulk power supplies (BPS) is provided by two 60-mm fans contained within each
BPS. Air flows into the front of the BPS and is exhausted out of the top of the power supply
though upward facing vents near the rear of the supply. The air is then ducted out of the rear of
the chassis.

PCI/Mass Storage Section Cooling

Six 92-mm fans located between the mass storage devices and the PCI card cage provide airflow
through these devices. The PCI fans are powered off of housekeeping power and run at full
speed at all times. The air is pulled through the mass storage devices and pushed through the
PCI card cage. Separation is provided between the PCI bulkheads to allow adequate exhaust
ventilation and to help reduce the localized airflow dead spots that typically occur at the faceplate
tail of each PCI card.

Standby Cooling

Several components within the chassis consume significant amounts of power while the system
is in standby mode. The system fans will run at a portion of full speed during standby to remove

38 System Specifications

the resulting heat from the cabinet. The fans within the power supply will operate at full speed
during standby.

The air-conditioning data in Table 2-10 are derived using the following equations.

• Watts x (0.860) = kcal/hour

• Watts x (3.414) = Btu/hour

• BTU/hour divided by 12,000 = tons of refrigeration required

NOTE: When determining power requirements, you must consider any peripheral equipment
that will be installed during initial installation or as a later update. Refer to the applicable
documentation for such devices to determine the power and air-conditioning that is required to
support these devices.

Acoustic Noise Specification

The acoustic noise specification for the servers is 55.6 db (sound pressure level at bystander
position). It is appropriate for dedicated computer room environments, not office environments.
The LwA is 7.4 Bels. Care should be taken to understand the acoustic noise specifications relative
to operator positions within thecomputer room or when adding servers to computer rooms with
existing noise sources.

Air Flow

The recommended server cabinet air intake temperature is between 20° C and 25° C (68° F and
77° F) at 960 CFM.

Figure 2-1 illustrates the location of the inlet and outlet airducts on a single cabinet. Air is drawn

into the front of the server and forced out the rear.

A Templates

This appendix contains blank floor plan grids and equipment templates. Combine the necessary
number of floor plan grid sheets to create a scaled version of the computer room floor plan.

Figure A-1 illustrates the overall dimensions required for the servers.

Figure A-1 Server Space Requirements

Equipment Footprint Templates

Equipment footprint templates are drawn to the same scale as the floor plan grid (1/4 inch = 1
foot). These templates show basic equipment dimensions and space requirements for servicing.
Refer to Figure A-2 (page 42).

The service areas shown on the template drawings are lightly shaded.

Use the equipment templates with the floor plan grid to define the location of the equipment
that will be installed in your computer room.

NOTE: Photocopying typically changes the scale of drawings copied. If you copy any templates,
then you must also copy all templates and floor plan grids.

Computer Room Layout Plan

Use the following procedure to create a computer room layout plan:

1. Remove several copies of the floor plan grid (Figure A-3).

Equipment Footprint Templates 41

2. Cut and join them together (as necessary) to create a scale model floor plan of your computer
room.

3. Remove a copy of each applicable equipment footprint template (Figure A-2).

4. Cut out each template selected in step 3; then place it on the floor plan grid created in step

2.

5. Position pieces until you obtain the desired layout, then fasten the pieces to the grid. Mark
locations of computer room doors, air-conditioning floor vents, utility outlets, and so on.

NOTE: Attach a reduced copy of the completed floor plan to the site survey. HP installation
specialists use this floor plan during equipment installation.
