N4000 and rp7400 Server Functionality
This section describes 11i functionality to enable 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 190
• “Improved ioscan Description Field for PCI Devices” on page 199
• “ttytype Support for the N4000 and rp7400 Console” on page 90
• “New stty Options” on page 91
• “SCSI Drivers scsi3 and c720” on page 82
• “Service Processor (GSP or MP)” on page 84
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,
Itanium-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
