The HP 9000 rp4410 and rp4440 were, like the HP 9000 rp3410 and rp3440, some of the last PA-RISC-based HP servers, based on up to four dual-core PA-8800 or PA-8900 processors and HP zx1 chipset, technically very similar to the rp3400s. The systems can be rack-mounted in 4U or be used stand-alone.

System architecture

Processors

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
Dual-port Gigabit Ethernet
USB2.0 controller
IDE controller

System 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 slots

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

Storage

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

External ports

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
