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.
- AIX stand for Advanced Interactive EXecutive, which is an IBM proprietary UNIX OS family running on IBM own workstations.
- AIX was the first OS with journaling filesystem.
- AIX Version 1, introduced in 1986 for the IBM RT PC workstation, was based on UNIX System V Releases 1 and 2.
- AIX Version 3 (also known as AIX/6000)
- AIX Version 4, introduced in 1994, added symmetric multiprocessing with the introduction of the first RS/6000 SMP servers
- AIX 4.3.3 was introduced in 1999
- P refers to Power series in terms of AIX.
- # oslevel -s –> To see AIX version
- 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.
- ODM Object Database Management –> Keeps LVM metadata, network configuration, etc which is not kept in configurations files.
- Power Processor BOX –> 2 HMC (Health Management Console)
- VIO server –> Multiple LPARs (Logical Partitions)
- Minimum Configuration for LPAR
1GB RAM/256MB RAM
10 GB disk space
1 Ethernet card
- 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.
