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 133
• “Improved ioscan Description Field for PCI Devices” on page 140
• “ttytype Support for the N4000 and rp7400 Console” on page 57
• “New stty Options” on page 57
• “SCSI Drivers scsi3 and c720” on page 49
• “Service Processor (GSP or MP)” on page 51
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 IA-64 Core Electronic Complex (CEC) components. This “hybrid” system
contains a new modular platform infrastructure. Whether PA-based, IA-64-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
