Overview

The HP 9000 servers rp4410 and rp4440 were, like their smaller rp3410 and rp3440 siblings, part of the last PA-RISC-based HP servers. They are driven by up to two or four dual-core PA-8800 or PA-8900 processors, based around the Itanium 2/IA64-capable HP zx1 chipset, technically very similar to the rp3400s. The systems can be rack-mounted in 4U or be used stand-alone.

System

CPU

The rp4410 (rp4410-4) supports 2-way multi-processing (SMP), the rp4440 (rp4440-8) up to 4-way multi-processing (SMP).

Dual-core PA-8800 900 MHz-1.0 GHz with 3 MB on-chip L1 and 32 MB off-chip L2 cache
Dual-core PA-8900 800 MHz-1.1 GHz with 3 MB on-chip L1 and 64 MB off-chip L2 cache
There probably was an upgrade path to Itanium 2/IA64 processors.

Chipset

The systems are based on the HP zx1 chipset with three main components — the MIO memory and I/O controller, the IOAs I/O adapters and the SMEs scalable memory expanders.

Pluto is the zx1 MIO memory and I/O controller and connects the system buses:
1. Processor bus of 6.4 GB/s for one or two dual-CPU modules
2. Two independent memory buses with each 6.4 GB/s
3. Eight I/O channels with aggregate 4.0 GB/s
Six zx1 SMEs scalable memory expanders attach to two independent zx1 memory buses
Six Mercury zx1 IOAs I/O adapters connect the PCI-X slots
1. PCI-X 64/133 I/O slot on two channels — 1.0 GB/s
2. PCI-X 64/133 I/O slot on two channels — 1.0 GB/s
3. Two PCI-X 64/66 I/O slots on one channel — 0.5 GB/s
4. Two PCI-X 64/66 I/O slots on one channel — 0.5 GB/s
5. Core I/O adapters like SCSI, Ethernet etc. on two channels — 1.0 GB/s
Dual-channel Ultra320 SCSI controller

Buses

An interesting aspect of the rp4400’s bus setup is that the same 6.4 GB/s processor bus is shared between up to two CPUs on the rp4410 and up to four CPUs on the rp4440.

Itanium 2/zx1 processor bus 6.4 GB/s
Two independent zx1 memory buses, 200 MHz, each 6.4 GB/s
Eight zx1 I/O channels/buses, aggregate 4.0 GB/s
Two PCI-X 64/133 I/O buses
Two PCI-X 64/66 I/O buses
SCSI-3 Ultra320 LVD storage I/O bus
IDE secondary storage I/O bus

Memory

PC2100 parity ECC DDR CL2 SDRAM DIMMs
16- or 32-DIMM carrier board
1 GB minimum memory
128 GB maximum memory
12.8 GB/s memory bandwidth
105ns memory latency

Expansion

Two PCI-X 64-bit/133 MHz slots, each on an independent bus, hot-plug
Four PCI-X 64-bit/66 MHz slots, on two shared buses, hot-plug
All PCI slots are 3.3 V

Drives

Two bays for 3.5″ Ultra320 LVD SCSI hard drives, hot-plug
Slimline bay for optional IDE CD or DVD drive

External

Three Serial RS232C DB9 for local console, remote console, general purpose
Two USB 2.0 ports
Two Gigabit Ethernet, TP/RJ45
Two Ultra320 SCSI ports
HP Integrated Lights Out iLO system management card with Fast-Ethernet Web console

Operating systems

HP-UX 11i v1, 11i v2, 11i v3
Linux could be a possibility, as the similar rp3400s are supported, albeit unofficially
