N4000 Server Functionality
This section describes 11i functionality to enable HP 9000 models HP
N4000 mid-range servers. Related operating system changes can be
found in the following sections of this document:
• “Changes to System Administration Manager (SAM)(updated for
June 2001)” on page 142
• “Improved ioscan(1M) Description Field for PCI Devices” on page 154
• “ttytype(1) Support for the N4000 Console” on page 62
• “New stty(1) Options” on page 63
• “SCSI Interface Driver scsi_c720” on page 54
• “Guardian Service Processor (GSP)” on page 55
With the exception of some new system build options, changes to HP-UX
11i for the N4000 servers will have little, if any, bearing on customers
using legacy PA-RISC systems.
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 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. New
kernel interfaces and platform modules are being provided to support all
current platforms, whether PA-based, IA-64-based, or hybrid.
Subsequent sections describe the following new platform architecture
components:
• Platform Support Modules (PSM)
The PSMs control specific hardware or functions of a given platform.
PSMs designed for the new functionality include the following:
— PAT PSM
— SBA PSM
— SAPIC PSM
