Hi again,<br />
<br />
A simple question, I now what HEA are, but not sure what's IVE. Are they the same? <br />
<br />
In my case I have 4 HEA ports, I have a LPAR with lhea port1 assigned working properly, but I dont know why HEA ports are grouped in two. See image attached.<br />
<br />
Thanks.<br />

HEA vs IVE on power6.

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
