rp8400 Server Model
HP rp8400 servers scale from one to four cells and include complete
support for hard partitions (nPartitions).
Figure 1-3 on page 39 shows an overview of the HP rp8400 server
hardware architecture.
You can configure a single nPartition using some or all cells, or can
configure up to two separate nPartitions within an HP rp8400 server
complex.
In a multiple-partition HP rp8400 complex, you would use cell 0 and its
core I/O in one nPartition, and use cell 1 and its core I/O in the other
nPartition. Any other cells (cells 2 and 3) could be assigned to either of
the two nPartitions, or could be unassigned.
The HP rp8400 server model includes these features:
• A single server cabinet that includes all cells, I/O chassis, processors,
memory, PCI cards, and core I/O.
• From one to four cells. Each cell has up to four PA-RISC processors
and up to 16 DIMMs.
• Two PCI I/O chassis that share the same chassis hardware.
One I/O chassis is connected to cell 0, the other is connected to cell 1.
Each I/O chassis has 8 PCI card slots, numbered from 1 to 8.
• Up to two core I/O devices, one connected to cell 0, and the other
connected to cell 1.
• A total server complex capacity of: 4 cells, 16 processors, 64 DIMMs,
and 16 PCI card slots.
• The model string for HP rp8400 servers is 9000/800/S16K-A.
HP rp8400 servers include a single server cabinet that can be
rack-mounted or stand-alone.
