HP 9000 rp4410 & rp4440
4.38 HP 9000 rp4410 & rp4440
4.38.1 Overview
Time of introduction: 2004
The rp4400 series rp4410 and rp4440 servers are, as their smaller rp3410 and rp3440 siblings, one of
the last PA-RISC-based HP servers. They are driven by up to two (rp4410) or four (rp4440) dual-core
PA-8800 Mako or PA-8900 processors. The rp4400s are based around the Itanium 2/IA64-capable HP
zx1 chipset, and technically very similar to the rp3400’s architecture. The systems can be rack-mounted
(4U) or used stand-alone.
List price at time of introduction: US $21,000 for a (single-CPU, dual-core) rp4440.
4.38.2 Internals
CPU
rp4410
� 1 or 2 dual-core PA-8800 900 MHz-1.0 GHz with 1.5 MB/1.5 MB on-chip I/D L1 cache and
32 MB off-chip L2 cache each
or
� 1 or 2 dual-core PA-8900 800 MHz-1.1 GHz with 1.5 MB/1.5 MB on-chip I/D L1 cache and
64 MB off-chip L2 cache each
rp4440
� 1, 2 or 4 dual-core PA-8800 900 MHz-1.0 GHz with 1.5 MB/1.5 MB on-chip I/D L1 cache and
32 MB off-chip L2 cache each
or
� 1, 2 or 4 dual-core PA-8900 800 MHz-1.1 GHz with 1.5 MB/1.5 MB on-chip I/D L1 cache and
64 MB off-chip L2 cache each
It is probably possible to upgrade the CPUs to Itanium 2/IA64 processors.
Chipset
The systems are based on HP’s zx1 chipset, which consists of three main components — the MIO (memory
and I/O controller), the IOAs (I/O adapters) and the SMEs (scalable memory expanders):
� Pluto zx1 MIO (memory and I/O controller) is the main chipset controller and connects the three
central system buses:
1. Processor bus (6.4 GB/s) for one (rp4410) or two (rp4440) dual-CPU modules
2. Two independent memory buses (each 6.4 GB/s)
3. Eight I/O channels (aggregate 4.0 GB/s, via the IOAs, see below)
� Six zx1 SMEs (scalable memory expanders) attach to two independent zx1 memory buses (each
6.4 GB/s)
