"AIX"
4/5
What do you like best about IBM AIX?

AIX is a great, secure Unix OS. With smitty it is easy to use even for novices. The IBM Power CPU is a great processor but I wish AIX could run on Intel. Review collected by and hosted on G2.com.

"Solid reliable operating system"
4/5
What do you like best about IBM AIX?

Great for uptime and reliability. The ability to shrink filesystem size live without issue makes it a better LVM than Linux in my opinion. IBM's support is pretty good. The granularity of control of resources with IBM's virtualization is much better than other virtualization options. Review collected by and hosted on G2.com.

What do you dislike about IBM AIX?

Upfront cost is a higher which means most organizations don't pay for enough hardware to be n+1 It's more of a niche operating system which means most software companies don't support it well or port their application to it with little support or missing features.

"AIX Review for running Oracle Products"
3.5/5
What do you like best about IBM AIX?

Well, it's a Unix-like Operating System, nothing new to someone like me. I am an Oracle DBA, a Middleware admin, and I have worked with Linux Red Hat, HPUX, and Oracle Linux. The only advantage I have detected so far is the nmon utility; it's great for monitoring memory, CPU usage among other important metrics. The LPAR reports on CPU and memory are very good, also the filesystem cache feature is great, it puts the most user files on memory cache, using idle memory for this. Review collected by and hosted on G2.com.

What do you dislike about IBM AIX?

I guess it offers the same as its competitors, Power 8 systems run okay, its performance is great. Actually, I guess I have zero complaints about this product. Review collected by and hosted on G2.com.
