Operating Systems AIX What's the difference between VIOS and LPAR? Post 302522610 by petervg on Monday 16th of May 2011 03:39:13 AM

Hi Itik,

Lpars are virtual systems created on POWER systems from IBM. Lpars run their own OS and run independently from other LPARs on the same iron.

A vios is a lpar with a dedicated task: providing virtual storage devices to other LPARs. Depending on your needs you will install at least 1 vios and multiple lpars. Actual applications should normaliter be run in a lpar and not the vios.

Lpars are installed with a system called HMC.
