N4000 and rp7400 Server Functionality
This section describes 11i functionality to enable HP 9000 model’s HP N4000 and rp7400
mid-range servers. Related operating system changes can be found in the following
sections of this document:
•“Changes to System Administration Manager (SAM)” on page 168
•“Improved ioscan Description Field for PCI Devices” on page 176
•“ttytype Support for the N4000 and rp7400 Console” on page 73
•“New stty Options” on page 74
•“SCSI Drivers scsi3 and c720” on page 64
•“Service Processor (GSP or MP)” on page 67
With the exception of some new system build options, changes to HP-UX 11i for these
servers will have little, if any, bearing on customers using legacy PA-RISC systems.
NOTE For the purpose of this document, all systems prior to N4000 are termed “legacy”
(including B-, C-, and D-Class low-end systems, K-Class mid-range systems, and T- and
V-Class high-end systems).
Platform Infrastructure
The HP N4000 and rp7400 servers are the first HP systems based on PA-RISC
processors with Itanium Core Electronic Complex (CEC) components. This “hybrid”
system contains a new modular platform infrastructure. Whether PA-based, IPF-based,
or hybrid, new kernel interfaces and platform modules are being provided to support all
current platforms.
Subsequent sections describe the following new platform architecture components:
• Platform Support Modules (PSM)
The PSMs control specific hardware or the functions of a given platform. PSMs
designed for the new functionality include the following:
— PAT PSM
— SBA PSM
— SAPIC PSM
• Context Dependent I/O module (CDIO)
Because of the hierarchal dependency requirements of some platform modules, not
all new platform code is handled by PSMs. The following CDIOs are included in
HP-UX:
— CB CDIO
— LBA CDIO
— PCI CDIO
— PCItoPCI CDIO
