HP 9000 rp4410 and rp4440 were 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, released by HP in 2004.

rp44x0 are technically very similar to HP 9000 rp3410 and rp3440 servers, based on the same zx1 architecture and PA-RISC processors. The systems can be rack-mounted in 4U or be used stand-alone.

HP 9000 rp4410 were introduced in 2005
HP 9000 rp4440 were introduced in 2004 for $21,000

Architecture

Chipset

HP 9000 rp44* are based on an HP zx1 Itanium 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
