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 thataccommodatesupto64GBofmemory;PCI-XI/O,andinternalperipherals,includingdisks andDVD/tape.ItshighavailabilityfeaturesincludeN+1hot-pluggablefansandpower,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-backCellController(CC)connectionincreasesperformanceandreduces 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 approximately1GB/sec. TheSBAconvertstheSBAlinkprotocolinto“ropes.”Aropeisdefined 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.

Detailed HP 9000 rp7420 Server Description

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,ResetCircuit,andPlatformDependentHardware(PDH)RiserBoardInterface.The busesincludetwoFrontSideBuses(FBS0andFBS1),aMemory(MID)bus,aCrossbar(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 requiredvoltagerails.TheDC-to-DCconvertersonthecellboarddonotprovideN+1redundancy.

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 accesspaths,eachpathhavingitsownaddressbus,controlbus,databus,andDIMMs.Inpractice, 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

ThePlatformDependantHardwareRiserboardisadaughtercardforthecellboard. Itcontains a micro-processor memory interface microcircuit, processor-dependent hardware including the processor-dependent code (PDC), flash memory, and a manageability microcontroller, called thePlatformDependantHardwareController(PDHC)withassociatedcircuitry.ThePDHobtains 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.

Cells and nPartitions

A cell board that has an I/O link to a bootable device and a console (usually supplied by an MP coreI/Ocard)isapotentialbootcell. ThecellthatcontainsthebootconsoleI/Opathisthecalled therootcell.Bothcellsarepotentialrootcells.TheprimaryordefaultrootcellinasinglenPartition 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).

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.

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 aremovablemediadeviceisrequiredonthemassstoragebackplane.Themassstoragebackplane incorporates a circuit that enables power to the internal removable media device to be programmatically cycled.
