AIX 5L安装的基本配置（英文）

Recommended configuration for a basic AIX 5L installation

 

When installing your AIX 5L system, it is important to understand the basic usage
of the system. This enables you to adequately design a system capable of
handling its workload.
Consider the following list of recommendations for a basic installation:
 Hard disks
Use at least two physical volumes (PV) to be used by rootvg. Each of the
volumes needs to be able to handle the operating system on its own. These
physical volumes need to be mirrored. The operating system is not more than
3 GB in size, but 5 GB advised for future growth, maintenance upgrades, and
fixes.

 

 File systems
Some applications use root file systems as their root for binaries, and this can
be hard coded. Try to isolate the binaries from the root file system by using a
separate file system with a mount point pointing to a root file system. For
example, if an application uses a directory such as /usr/tivoli, create a file
system with a mount point of /usr/tivoli. In doing that, /usr becomes a file
system and /usr/tivoli another file system.

 

 Paging space
This is controlled mainly by the applications running on the system. For
example, some applications require that your paging space be three to four
times the size of your real memory. AIX 5L provides the following default sizes
based on your initial configuration.
Paging space can use no less than 16 MB, except for hd6, which can use no
less than 64 MB in AIX Version 4.3 and later. Paging space can use no more
than 20% of total disk space. If real memory is less than 256 MB, paging
space is twice the real memory. If real memory is greater than or equal to 256
MB, paging space is 512 MB.

 

 System dump device
After system installation, use the sysdumpdev -e command to estimate the
size of the system dump device. AIX 5L Version 5.3 isolates the dump device
from the default hd6 to lg_dumplv. Make sure that dumpcheck is activated in
cron. It periodically estimates the size of the system dump and compares it
with the size of the dump device. It will notify the administrator when the dump
device becomes too small.

 

 Memory
This depends on the application. The more the memory you have, the more
chances of improving performance. This is only a subset of performance
factors.

 

 Network
If possible, we recommend two or more physical adapters for both
redundancy and load balancing. You might need a separate adapter to run
backups.
