Unix VIO vs Dynamic LPAR

Can you have a Dynamic LPAR without VIO and if yes is there a benefit to having both? I am attempting to implement VIO and Resource pooling at my company and want to understand the limitations.

Also, I have been told the managing and allocation of the Logical Volumes is a time consuming task as they have to be managed at the SAN level as well as the VIO partion, is this correct as well?

Thank you in advance

libroar - RoarAudio sound library roarvio - RoarAudio virtual IO layer SYNOPSIS
#include <roaraudio.h> struct roar_vio_calls; DESCRIPTION
The RoarAudio VIO interface is RoarAudio's IO abstraction layer. It provides basic IO functions such as read and write independing on the underlaying IO. For Example can you open a plain or a gziped file via the VIO layer. After a successful open both objects behave the same, libroar takes care about the compression in the gzip case. TUTORIALS
Tutorials can be found in roartutvio(7). IMPORTANT FUNCTIONS
There are several important functions. This is a small list of the most important ones. Opening roar_vio_open_file(3), roar_vio_open_fh(3), roar_vio_open_stdio(3), roar_vio_open_dstr(3), roar_vio_open_proto(3). While there are a lot functions important for opening files the most important one is roar_vio_open_dstr(3). It opens a stream based on URLs that can point to local files or files on remote machines. It also can handle compression and encryption. Closing roar_vio_close(3), roar_vio_shutdown(3) Reading and writing roar_vio_read(3), roar_vio_write(3) Seeking and positioning roar_vio_lseek(3) Non-Blocking and Asyncron IO roar_vio_nonblock(3), roar_vio_sync(3), roar_vio_select(3) Networking and Sockets roar_vio_accept(3) String handling roar_vio_printf(3) BUGS
