An example would be the recommendation that the PE (protective earthing) conductor be green with yellow stripes. This requirement is a North American directive and does not override the local code requirements for a country outside North America.

1 Introduction

The hp rp7410 is a member of Hewlett-Packard’s business-critical computing platform family: a mid-range, mid-volume server, positioned as an upgrade to the current N-Class product in the PL-1X product line. It provides increased performance over its predecessor but in a smaller volume. Its shallower depth allows it to fit in a standard rack. In addition to the hp rp7410, Hewlett-Packard offers a series of cost-effective servers based on the hp rp7410 with somewhat less performance. See “hp rp7405 Servers” on page 5.

Introduction

hp rp7405/rp7410 Overview

The hp rp7405/rp7410 is a 10U, 8-way SMP, rack-mount server that accommodates up to 32 GB of memory (64 GB available at a later date); PCI-4X 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 cards and internal disks. It uses the PA8700 PA-RISC processors.

Introduction

hp rp7405/rp7410 Overview

Improvements over its predecessor, N4000, include:

• Better availability and up time

• Depth optimized (shallower, fewer racking issues)

• Performance density increase

• Performance increase

• Internal removable media

• More internal disks

• Optimal power cord quantity (2 min., 4 max)

• Enabled for cell hot-plug, dual-partition, dual and/or redundant MP Core I/O

• More PCI slots (up to 16)

• Upgradeable to PCI-X

• Superset of MP Core I/O functionality

Cell Board

The cell board contains the processors, main memory, and the CC ASIC that interfaces the processors and memory to the off-board I/O. The CC provides a crossbar connection, which allows communication with other cell boards in the system. It connects to the PDH and SINC hardware. Each cell board holds up to 16 DIMMS. There can be one or two cell boards installed in a server. The cell boards have hot-plug capability.

System Backplane

The system backplane comprises the system clock generation logic, the system reset generation logic, DC-to-DC converters, power monitor logic, and two Local Bus adaptor (LBA) link-to-PCI converter ASICs. It also includes connectors for attaching the cell boards, PCI backplane, MP Core I/O MP/SCSI boards, SCSI cables, bulk power, chassis fans, front panel display, intrusion switches, and the system scan card. Unlike Superdome or the rp8400, there are no XBC chips on the system backplane. The “crossbar-less” back-to-back

CC connection increases performance and reduces costs.

There are only two sets of cell board connectors, because the server has only two cells

Also, 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 Backplane.

I/O Subsystem

All of the I/O is integrated into the system by way of the PCI busses. The CC on each cell board communicates with one SBA 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”. SBA can support up to 16 of these high-speed bi-directional links for a total aggregate bandwidth of approximately 4 GB/sec. The LBA acts as a bus bridge, supporting either one or two ropes, and capable of driving either

PCI-2x Turbo (33 MHz x 64 bits) or PCI-4 Twin Turbo (66 MHz x 64 bits) respectively.

Cell Board

The cell board contains the processors, main memory, and the cell controller (CC) ASIC that interfaces the processors and memory to the off-board I/O. Shown in Figure 1-4 is the CC. This is the heart of the cell board. The CC provides a crossbar connection, which allows communication with other cell boards in the system. It connects to the PDH and SINC hardware. Each cell board holds up to 16 DIMMs. There can be one or two cell boards installed in an system. The cell boards have hot-plug capability.

Introduction

Detailed hp rp7405/rp7410 Description

The hp rp7405/rp7410 has a 48V distributed power system and receives the 48V 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 several major buses including:

• Runway buses for each of the four processors

• Two memory buses (one going to each half of the main memory array)

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

• Incoming and outgoing crossbar bus that goes off board to the other cell boards

• PDH bus that goes to the PDH/SINC circuitry

All of these buses come together at the CC chip.

Due to space limitations on the cell board the PDH/SINC circuitry resides on a riser board that plugs at a right angle into the cell board. The cell board also includes clock circuits, test circuits and de-coupling capacitors.

Figure 1-6 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 SDRAMs on the DIMMs.

Data transferred between the CC and SDRAM passes through custom VLSI circuits (M2) that are bit-sliced; four form one 72-bit CC memory data bus. These circuits perform speed and width conversion between the SDRAM and MID busses. They also perform the write (tag update) portion of a read-modify-write (RMW) access. The CC memory data busses are bi-directional and run at 250 MT/s (million transfers per second). These links are self-clocked in that a pair of clock strobes is passed along with the data so that phase realignment can be done by the receiver.
