HP-UX 11i provides new hardware enablement, additional software
functionality, and various HP-UX applications bundled into Operating
Environments. HP-UX 11i is the recommended next-level enterprise
release for all HP-UX systems currently running HP-UX 10.x or 11.0. See the HP-UX 11i Installation and Update Guide,
part number 5185-6511, for information on disk and memory requirements. Performance Considerations | |
The performance of HP 9000 servers and applications with the
HP-UX 11i Operating Environments is as good or better as compared
to HP-UX 11.0 installed in the same configuration. It must be kept
in mind, however, that in the vast majority of cases, HP-UX is likely
to be installed as part of one of the predefined HP-UX 11i Operating Environments. The HP-UX 11i Operating Environments provide numerous benefits,
including lower cost as well as simplification of product ordering,
installation, integration, and support. While the HP-UX 11i Operating
Environments provide these desirable benefits, they all involve
more software components and daemons than a base HP-UX 11.0 or HP-UX
11i operating system. Because of this, an Operating Environment may
have somewhat greater system overhead compared to a base operating
system installation. This increase in system overhead, while modest,
can nevertheless make it erroneously appear that system and application
performance are degraded with HP-UX 11i as compared to HP-UX 11.0.
In fact, performance with HP-UX 11i is generally better than HP-UX
11.0 when the software configurations are the same. While not recommended, one of the options for installing HP-UX
11i is as a base operating system only, without an Operating Environment.
Installing HP-UX 11i as a base operating system will give the greatest
performance and the lowest system overhead but eliminates the advantages
provided by the HP-UX 11i Operating Environments. The HP-UX 11i Operating Environments
(OE) | |
Beginning with HP-UX 11i, the operating system is delivered
as part of an HP-UX Operating Environment (OE), an integrated and
tested software solution containing the operating system and selected
applications. The following software bundles are always delivered with an
Operating Environment. Thus, if you do a minimum install, these
bundles, plus the HP-UX applications within each OE, will be loaded: HPUXBase32 or HPUXBase64, which consist of operating system commands and libraries
bundled for either 32- or 64-bit systems. HPUXBaseAux, which includes system manageability software
such as Software Distributor (SD) and the Partition Manager (parmgr).
This additional required core software is also referred to as the
Auxiliary OS. Network and I/O drivers, installed by default, that
are required by the operating system and other selectable drivers.
The default drivers include: FibrChanl-00: drivers for the PCI Fibre Channel HB adapter
(64-bit OS) RAID-00: driver for the PCI RAID controller (64-bit OS) FDDI-00: FDDI drivers (32-bit OS) GigEther-00: 1000Base-T/SX (Gigabit Ethernet) drivers GigEther-01: 1000Base-T/SCSI driver added to pre-enable future
systems (64-bit only)
(See “Selectable Network Drivers ” in Chapter 4 “HP-UX 11i Operating Environment Applications” for a list of the selectable
drivers.) OnlineDiag, which provides HP-UX 11i Online Diagnostics. CDE-English: CDE language (such as for English or alternate
languages).
Operating Environments for HP Commercial ServersThe following lists each 11i Operating Environment available
for HP servers. These Operating Environments are supported on all
HP 9000 servers, including technical servers. They are not supported
on technical workstations. HP-UX 11i OE is the standard Internet
server environment for HP-UX systems. It includes Java, the Apache
Web Server, Netscape Communicator, WebQoS, and other applications.
[2] This
OE is included without additional charge. HP-UX 11i Enterprise OE contains the HP-UX 11i OE
and additional applications to enable an enterprise-level server.
Products include OnLineJFS 3.3, GlancePlus, MirrorDisk/UX, and other
applications.[2] HP-UX 11i Mission Critical OE contains both the
HP-UX 11i OE and the HP-UX 11i Enterprise OE plus applications to
enable a mission-critical server, such as MC/ServiceGuard and HP-UX
Workload Manager.[2]
| | | |  | NOTE: The 11i, Enterprise, and Mission Critical OEs are also
supported on technical servers. (They are not supported on technical
workstations, however.) | | | | |
Operating Environments for HP Technical Workstations
and Technical Serversupdated for
June 2001The following are the 11i Operating Environments available
for HP 9000 technical workstations and technical servers: HP-UX 11i Minimal Technical OE (new
for June 2001) contains all the base functionality that is common
to the other four OEs, including the base 32/64 bit HP-UX Operating
System, network drivers, and other always-installed functionality. However,
it includes only a sparse set of high-demand applications so as
not to increase purchase costs, support costs, or license costs
over the base OE.[2] HP-UX 11i Technical Computing OE contains applications
to enable a technical workstation or technical server.[2]
