Two-Cell nPartition Server Model

The following cell-based HP servers scale from one to two cells:
• The HP rp7405/rp7410 server has single-core HP PA-RISC processors.
The model string is: 9000/800/rp7410.
• The HP rp7420 server has dual-core HP PA-RISC processors: PA-8800 processors, which
provide two processor cores per processor socket.
The model string is: 9000/800/rp7420.
• The HP rp7440 server has dual-core HP PA-RISC processors: PA-8900 processors, which
provide two processor cores per processor socket.
The model string is: 9000/800/rp7440.
• The HP rx7620 server has Intel® Itanium® 2 processors, either single-processor modules or
HP mx2 dual-processor modules.
Both HP mx2 dual-processor modules and single Itanium 2 processors can exist in the same
complex, but they cannot be mixed in the same nPartition.
The model command output is: ia64 hp rx7620 server.
• The HP rx7640 server has single-core or dual-core Intel® Itanium® 2 processors.
The model command output is: ia64 hp rx7640 server.

On the two-cell HP servers you can configure a single nPartition using one or both cells, or can
configure up to two separate nPartitions within the server complex. In a two-nPartition complex,
you use cell 0 and its core I/O in one nPartition, and use cell 1 and its core I/O in the other
nPartition.
The two-cell HP server models includes these features:
• A single server cabinet that includes all cells, I/O chassis, processors, memory, PCI cards,
and core I/O.
• Either one or two cells. Each cell has up to four processor sockets 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.
