Introduction to IBM AIX OS ?

IBM AIX is a very reliable, wide Operating system. I can’t explain everything about this OS.

However we can look at its small introduction point wise.

For further understanding, please check out the wiki page and IBM support website for AIX.

1. AIX stand for Advanced Interactive EXecutive, which is an IBM proprietary UNIX OS family running on IBM own workstations.
2. AIX was the first OS with journaling filesystem.
3. AIX Version 1, introduced in 1986 for the IBM RT PC workstation, was based on UNIX System V Releases 1 and 2.
4. AIX Version 3 (also known as AIX/6000)
5. AIX Version 4, introduced in 1994, added symmetric multiprocessing with the introduction of the first RS/6000 SMP servers
6. AIX 4.3.3 was introduced in 1999
7. P refers to Power series in terms of AIX.
8. # oslevel -s –> To see AIX version
9. VRMF- Version, Release, Modification, Fixes :- Is the way how an AIX OS is named to tell us the OS version, release, modification level, and fixes level.
10. ODM Object Database Management –> Keeps LVM metadata, network configuration, etc which is not kept in configurations files.
11. Power Processor BOX –> 2 HMC (Health Management Console)
12. VIO server –> Multiple LPARs (Logical Partitions)
13. Minimum Configuration for LPAR
    1GB RAM/256MB RAM
    10 GB disk space
    1 Ethernet card
    1 Processor
14. 1/10 in P7 –> 10 virtual Processors can be created in 1 Physical Power Processor.
    1/20 in P8 –-> 20 virtual processors can be created under 1 physical power processor.  If P8 has 20 processors, we can create at max 20*20 = 400 Virtual processors.
