Chris,

iASPs showed up in V5R3 and are for the most part software. They can,
perhaps even should, be on separate RAID cards (for performance) but you
can take a single drive and make it an iASP. There are two 'flavors'
one that holds only IFS objects and one that holds it's own database. It
even gets a name in WRKRDBDIRE and you connect to it with SQL CONNECT.
You can also use it with traditional RPG etc with SETASPGRP making that
iASP available to your job.

iASPs can be mirrored to another iASP without a SAN both locally and
remotely.

I need to learn more about these iASP's. What iSeries hardware level do
you need to be at to create iASP's within your system? What can be put
onto an iASP? What version of OS400, excuse me, i5OS is required to
support iASP's?

Can an iASP be mirrored to some remote SAN in near real time?

Chris:

By using iASP you would not have to create partitions. You would of
course need the mirror software (PowerHA or option 41) to do it.
