IRIX has available the XLV plexing option:
xlv(7M)
xlv(7M)

NAME
     xlv - logical volume disk driver

SYNOPSIS
     /dev/xlv/*
     /dev/rxlv/*

DESCRIPTION
     XLV devices provide access to disk storage as logical
volumes.  A logical
     volume is an object that behaves like a disk partition,
but its storage
     can span several physical disk devices.

     Using XLV, you can concatenate disks together to create
larger logical
     volumes, stripe data across disks to create logical
volumes with greater
     throughput, and plex (or mirror) disks for
reliability.  In addition, XLV
     enables you to change the configuration of volumes
while the volume is
     actively being used as a filesystem.

Hope this helps,
Dow
