2 nPartition Server Hardware Overview

This chapter describes the cell-based HP server models, including system capacities, model
strings, and differences among the cell-based server models.
Both HP 9000 servers and HP Integrity servers are discussed here.
• The HP 9000 series of servers has HP PA-RISC processors.
The cell-based HP 9000 servers include three generations of servers: the first-generation
models, models based on the HP sx1000 chipset, and models based on the HP sx2000 chipset.
• The HP Integrity series of servers has Intel® Itanium® 2 processors.
The cell-based HP Integrity servers either are based on the HP sx1000 chipset or are based
on the HP sx2000 chipset.

sx1000 Chipset for HP Servers

The second generation of cell-based servers is built around the HP sx1000 chipset. The sx1000
chipset supports both single-core and dual-core processors, including both HP PA-RISC and
Intel® Itanium® 2 processors.
The following servers use the HP sx1000 chipset:
• PA-RISC servers — HP rp7420, HP rp8420, HP 9000 Superdome (SD16A, SD32A, and SD64A
models).
• Itanium® 2-based servers — HP rx7620, HP rx7620-16, HP rx8620, HP rx8620-32, HP Integrity
Superdome (SD16A, SD32A, SD64A models).
The HP sx1000 chipset provides a scalable server architecture with high-bandwidth processor,
memory, and I/O busses. The HP sx1000 chipset includes interconnecting components such as
memory buffers, I/O bus adapters and host bridges, and cell controllers, which have built-in
low-level error correction.
One notable administration feature of HP servers built around the HP sx1000 chipset is
management processor (MP) support for access to the server using IPMI over LAN. For details
see "Remote and Local Management of nPartitions" (page

sx2000 Chipset for HP Servers

The third generation of cell-based HP servers is built around the HP sx2000 chipset.
The following servers use the HP sx2000 chipset:
• PA-RISC servers — HP rp7440, HP rp8440, HP 9000 Superdome (SD16B, SD32B, SD64B
models).
• Itanium® 2-based servers — HP rx7640, HP rx8640, HP Integrity Superdome (SD16B, SD32B,
SD64B models).
The HP sx2000 chipset provides a scalable server architecture with high-bandwidth processor,
memory, and I/O busses. The HP sx2000 chipset includes new cell boards with core I/O, new
system and I/O backplanes, new interconneting components, and the addition of a redundant
clock source that is hot-swappable.
HP servers built around the HP sx2000 chipset include management processor (MP) support for
access to the server using IPMI over LAN. For details see
