IBM AIX

You can plan for an IBM AIX computer system.

Page space allocation policy
AIX, by default, implements a late page space allocation policy, but you can change this default setting.
Asynchronous I/O
AIX® supports both kernelized asynchronous I/O to raw devices or Veritas Quick I/O devices and threaded asynchronous I/O to filesystem files (e.g., JFS). With KAIO, the Oracle process queues I/O requests in the kernel and are notified of I/O completion by an interrupt. In contrast, threaded asynchronous I/O uses multiple threads with each thread issuing a synchronous I/O to simulate the asynchronous I/O.
Auto-negotiation
You can review your auto-negotiation settings.
