1 Overview
The HP 9000 rp7420 server is a member of the HP business-critical computing platform family.
It is a mid-range, mid-volume server, positioned as an upgrade to the HP 9000 rp7410 server in
the PL-1X product line. The HP 9000 rp7420 server shares the same hardware as the HP 9000
rp7410 server with changes to the cell board, CPU modules, core I/O, and the PCI-X backplane.
The HP 9000 rp7420 server provides increased performance over its predecessor.
Introduction
The HP 9000 rp7420 server is a 10U, 8-socket symmetric multi-processing, rack-mounted server
that accommodates up to 64 GB of memory; PCI-X I/O, and internal peripherals, including disks
and DVD/tape.Its high availability features include N+1 hot-pluggable fans and power, redundant
power cords, and hot-pluggable PCI-X cards and internal disks. It currently uses dual core,
PA-RISC processors.

Introduction 17
Figure 1-2 HP 9000 rp7420 server (without front bezel)
System Backplane
The system backplane is comprised of the system clock generation logic, the system reset
generation logic, DC-to-DC converters, power monitor logic, and two Local Bus Adapter (LBA)
link-to-PCI converter ASICs. It also includes connectors for attaching the cell boards, the PCI-X
backplane, Management Processor (MP) Core I/O MP/SCSI boards, SCSI cables, bulk power,
chassis fans, the front panel display, intrusion switches, and the system scan card. Unlike the
Superdome or rp8400 servers, there are no Crossbar Chips (XBC) on the system backplane. The
“crossbar-less” back-to-back Cell Controller (CC) connection increasesperformance and reduces
costs.
Only half of the MP Core I/O board set connects to the system backplane. The MP/SCSI boards
plug into the backplane, while the LAN/SCSI boards plug into the PCI-X backplane.
18 Overview
Figure 1-3 System Backplane Block Diagram
System Backplane to PCI-X Backplane Connectivity
The PCI-X backplane uses two connectors for the System Bus Adapter (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 CC 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 central clocks drive all major chip set clocks. Therefore, these circuits represent a
system-wide single point of failure.
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 seen in Figure 1-4. The CC on cell
board 0 and cell board 1 each communicate with individual SBAs over the SBA link. The SBA
link consists of both an inbound and an outbound link with an effective bandwidth of
approximately 1 GB/sec. 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
bi-directional rope links for a total aggregate bandwidth of approximately 4 GB/sec. Each LBA
acts as a bus bridge, supporting either 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 cards.
Introduction 19
Figure 1-4 PCI-X Board to Cell Board Block Diagram
NOTE: PCI-X slots 1 through 7 are dual rope slots, while slot 8 is a single rope slot.
The PCI-X backplane is the primary I/O interface for HP 9000 rp7420 servers. It provides sixteen
64-bit, hot-plug PCI/PCI-X slots. Fourteen of the slots have dual ropes connected to the LBA
chips. The remaining two slots have a single rope connected to each LBA chip. Each of the sixteen
slots are capable of 66 MHz/33 MHz PCI or 133 MHz/66 MHz PCI-X. All sixteen PCI slots are
keyed for 3.3-volt connectors (accepting both Universal and 3.3-V cards). The PCI-X backplane
does not provide any 5-volt slots for the I/O cards. For more details, see Table 1-1.
The PCI-X backplane is physically one board but behaves like two independent partitions. SBA
0 and its associated LBAs and eight PCI-X slots form one I/0 partition. SBA 1 and its associated
LBAs and eight PCI-X slots form the other I/0 partition. One I/O partition can be powered down
separate from the other I/O partition.

Cell Board
The cell board contains several hardware blocks connected by several data buses. The major
hardware blocks are the Central Processor Units (CPUs), the Cell Controller, the Memory
Controllers, and the Memory. Minor hardware blocks include Clock Distribution, Power
Distribution, Reset Circuit, and Platform Dependent Hardware (PDH) Riser BoardInterface. The
buses include two Front Side Buses (FBS0 and FBS1), a Memory (MID) bus, a Crossbar (XB) bus,
and an I/O bus. All these blocks come together at the CC chip.
Figure 1-6 Cell Board
The HP 9000 rp7420 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.
Because of space limitations on the cell board, the PDH/PDHC circuitry resides on a riser board
that plugs into the cell board at a right angle. The cell board also includes clock circuits, test
circuits, and de-coupling capacitors.
Figure 1-7 shows a simplified view of the memory subsystem. It consists of two independent
access paths, each path having its own address bus, control bus, data bus, and DIMMs . In practice,
the CC runs the two paths 180 degrees out of phase with respect to each other to facilitate
pipelining in the CC. Address and control signals are fanned out through register ports to the
synchronous dynamic random access memory (SDRAM) on the DIMMs.
22 Overview
Figure 1-7 Memory Subsystem
PDH Riser Board
The Platform Dependant Hardware Riser board is a daughter card for the cell board. It contains
a micro-processor memory interface microcircuit, processor-dependent hardware including the
processor-dependent code (PDC), flash memory, and a manageability microcontroller, called
the PlatformDependant Hardware Controller(PDHC) with associated circuitry. The PDH obtains
cell board configuration information from cell board signals and from the LPM on the cell.
The PDH riser board contains circuitry that the cell board requires to function and, therefore,
each cell board must have a PDH riser installed before it is added to a server.
Central Processor Units
The cell board can hold up to eight (four dual-core) CPUs and can be populated with CPUs in
increments of two CPUs. On a cell board, the processors must be the same type and speed. Two
CPUs is the minimum configuration allowed on the HP 9000 rp7420 server. There are two
Frontside Buses (FBS), one for sockets 0 and 1, and one for sockets 2 and 3. Each FBS must have
either a CPU or a terminator at the end of the bus or the board does not operate properly. There
cannot be a terminator board in socket 1 or socket 3 locations. For the CPU load order that must
be maintained when adding CPUs to the cell board, see Table 1-2. For the locations on the cell
board for installing CPUs, see Figure 1-8.

DIMMs
Custom designed by HP, each DIMM contains 36 x 4 SDRAM memory components similar to
PC-133 memory, but qualified to run at 125 MHz. They have a low-voltage TTL interface. The
CEC does not support traditional DRAMs.
The HP 9000 rp7420 server supports DIMMs with 256 MB, 512, MB, 1 GB, and 2 GB capacity.
Table 1-3shows each DIMM supported with its associated capacity, the resulting total system
capacity, and the memory component density.
DIMMs mustbe loaded in sets of two at specific locations. For best performance, HP recommends
loading sets of eight DIMMs.

24 Overview
Main Memory Performance
Latency to main memory is an important parameter in determining overall system performance.
With memory buses running at 125 MHz, the latency for a page hit is 8.5 cycles (68 ns), the latency
for a page closed is 11.5 cycles (92 ns), and the latency for a page miss is 14.5 cycles (116 ns).
Valid Memory Configurations
The HP 9000 rp7420 server is capable of supporting as little as 0.5 GB of main memory using two
256 MB DIMMs installed on a single cell board and as much as 128 GB by filling all 16 DIMM
slots on both cell boards with 4 GB DIMMs.
DIMMs must be loaded in sets of two at specified locations on the cell board. Two DIMMs are
called a rank; two ranks would be equivalent to four DIMMs, three ranks would be six DIMMs,
and so on. The DIMMs must be the same size in a rank. The DIMMs across all cells in a partition
should have identical memory loaded. Figure 1-9 shows the DIMM slot layout on the cell board.
For DIMM load order, see Table 1-4.
A quad seen in Figure 1-9 is a grouping of four DIMMs. Configurations with 8 or 16 DIMM slots
loaded are recommended. The DIMM sizes in a quad can be different but the DIMMs in a rank
must be the same size.

Cells and nPartitions
A cell board that has an I/O link to a bootable device and a console (usually supplied by an MP
core I/O card) is a potential boot cell. The cell that contains the boot console I/O path is the called
the root cell. Both cells are potential root cells. The primary or default root cell in a single nPartition
system is the bottom cell (cell 1).
An nPartition (also called a Protection Domain) is a cell or cells running the same operating
system and sharing processes and memory space among the components. Each nPartition must
have one root cell and can contain both cells. The HP 9000 rp7420 server has only two possible
nPartition configurations: single or dual. The additional cell that can be part of the nPartition
does not require I/O links or MP core I/O cards.
In the single nPartition case, if two cells are present, either cell can be the root cell, assuming
both cells have MP core I/O functionality present. If only one cell is present, that cell is the root
cell (and should be cell 1).
In the dual nPartition case (two cells required), each nPartition consists of one cell, and each cell
must be a root cell. The ability to interconnect two cells in one nPartition or isolate the cells in a
dual nPartition system provides system configuration flexibility. System partitioningis configured
by the system MP.
NOTE: Partition configuration information is available on the HP website at http://
docs.hp.com. For more detail, see the HP Systems Partition Guide: Administration for
nPartitions.
Internal Disk Devices for the HP 9000 rp7420 server
In an HP 9000 rp7420 server, the top internal disk drives connect to cell 1 through the core I/O
for cell 1. Both of the bottom disk drives connect to cell 0 through the core I/O for cell 0.
The CD/DVD/DAT drive connects to cell 1 through the core I/O card for cell 1.
26 Overview
Figure 1-10 Internal Disks
MP/SCSI MP Core I/O Board
The HP 9000 rp7420 server accommodates two sets of MP Core I/O functionality. Each MP/SCSI
core I/O board set consists of a MP/SCSI board and a Procurium LAN/SCSI board. At least one
MP/SCSI board is required (independent of partitions). An additional MP/SCSI board can be
added as well (and is required in a dual partition system). Both MP/SCSI boards are oriented
vertically and plug into the system backplane. The MP/SCSI board incorporates a dual channel
Ultra160 SCSI controller.
Procurium LAN/SCSI Board
At least one Procurium LAN/SCSI board is required for the minimum system configuration; two
are required in a dual partition system. The Procurium board is a standard PCI form factor card
with PCI card edge connectors. The PCI-X backplane has one slot location reserved for the
required Procurium board and another that can accommodate either a Procurium board or any
other supported add-in PCI-X card. The Procurium board is hot-pluggable.
Mass Storage (Disk) Backplane
Internal mass storage connections (to disks) are routed on the mass storage backplane, having
connectors and termination circuitry. All disks are hot-pluggable. The HP 9000 rp7420 server
accommodates one internal, removable media device. Therefore, only one power connector for
a removable media device is required on the mass storage backplane. The mass storage backplane
incorporates a circuit that enables power to the internal removable media device to be
programmatically cycled.

Server Description
Dimensions
The dimensions of the HP 9000 rp7420 server are as follows:
• Width: 44.45 cm (17.5 inches), constrained by EIA standard 19 inch racks
• Depth: Defined by cable management constraints to fit into standard 36-inch deep racks
(Rittal/Compaq, Rosebowl I):
25.5 inches from front rack column to PCI connector surface
26.7 inches from front rack column to MP Core I/O connector surface
30 inches overall package dimension, including 2.7 inches protruding in front of the front
rack columns
• Height: 10U – 0.54 cm = 43.91 cm (17.287 inches). This is the appropriate height for a product
that consumes 10U of rack height while allowing adequate clearance between products
directly above and below this product. Fitting four server units per 2 m rack and upgrade
of current 10U height products in the future are the main height constraints.
System Chassis
The mass storage section located in the front enables access to removable mass storage devices
without removal of the bezel (not shown). This is especially helpful when the system is mounted
in the lowest position in a rack. The mass storage bay accommodates one 5.25-inch removable
media device and up to four 3.5-inch hard drives. The front panel display board, containing
LEDs and the system power switch, is located directly above the 5.25-inch removable media bay.
Below the mass storage section and behind a removable bezel are two PCI DC-to-DC power
converters.
The BPS section is partitioned by a sealed metallic enclosure located in the bottom of the package.
This enclosure houses the N+1 fully redundant BPS.
28 Overview

The PCI-X card section, located toward the rear, is accessed by removing the top cover.
The PCI OLR fan modules are located in front of the PCI-X cards. These six 9.2-cm fans are housed
in plastic carriers. They are configured in two rows of three fans.
The MP/SCSI MP core I/O boards are positioned vertically at the rear of the chassis.
The PCI-X card bulkhead connectors are located in the top rear portion of the chassis.
Four OLR system fan modules, externally attached to the chassis, are 15-cm (6.5-inch) fans. Two
fans are mounted on the front surface of the chassis and two are mounted on the rear surface.
The two hot-pluggable N+1 redundant BPS provide a wide input voltage range. They are installed
in the front of the chassis, directly under the front fans.
A cable harness that connects from the rear of the BPSs to the system backplane provides DC
power distribution.
Access the system backplane by removing the left side cover. The system backplane inserts by
a guide/insertion mechanism using a single large jack screw assembly.
SCSI ribbon-cable assemblies route from the mass storage area to the backside of the system
backplane and to the Procurium PCI MP core I/O card.
Access the cell boards from the right side of the chassis behind the removable side cover.
