HP-UX 11i provides new hardware enablement, additional software functionality,
and various HP-UX applications bundled into an Operating Environment. It
is the recommended next-level enterprise release for all HP-UX systems
currently running HP-UX 10.x or 11.0. Installing or updating to HP-UX 11i will require at least
a 4GB root disk and a minimum of 64MB of memory. See the HP-UX 11i Installation and Update Guide, part no. B2355-90703,
for complete information. 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.
For more information on Operating Environments, see the next section. The HP-UX 11i Operating Environments provide numerous benefits. These
include 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, the Operating Environments 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 Operating Environment (OE) | |
Beginning with HP-UX 11i, the operating system is delivered as
part of the HP-UX Operating Environment (OE). An Operating Environment
is 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 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: drivers for the PCI RAID card (64-bit OS) FDDI-00: FDDI drivers (32-bit OS) GigEther-00: 10/100/1000Base Ethernet drivers
See “Network Drivers
(new)” in Chapter
5 for a list of the selectable drivers. OnlineDiag which provides HP-UX 11.0 Online Diagnostics, B.11.11. CDE-English: CDE language such as for English or alternate languages.
The following lists each 11i Operating Environment available
for HP 9000 servers: HP-UX 11i OE which is the standard
Internet server environment for HP-UX systems. It includes Java,
the Apache Web Server, Netscape Communicator, WebQoS, and other
applications. This OE is included without additional charge. HP-UX 11i Enterprise OE which 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. HP-UX 11i Mission Critical OE which 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
Workload Manager.
All products included with each OE are described in Chapter
4. Some applications may require post-installation configuration;
see the HP-UX 11i Installation and Update Guide,
part no. B2355-90703, for details. For HP 9000 Technical Workstations and Technical ServersThe following is the 11i Operating Environment available for
HP 9000 technical workstations and technical servers: HP-UX 11i Technical Computing OE which
contains the HP-UX 11i OE and additional applications to enable
a technical workstation or technical server. The other OEs listed
above are all supported on technical servers only and not on technical
workstations.
All products included with this OE are described in Chapter
4. Some applications may require post-installation configuration;
see the HP-UX 11i Installation and Update Guide,
part no. B2355-90703, for details. |
