On an AS/400 or Iseries machine the only way to run Linux is in a LPAR (Logical Partition of hardware resources). And Linux or other OSses like AIX and OS/400 can run together several times on such a machine with a virtual IP-lan between the different partitions. However, the main OS always must be OS/400, so this means high costs. The IBM and alike guys ask a lot money for their machines because of the high software and maintanance costs.
The original mentioned new Linux feature have a something to do with clustering. You can cluster two Linux partitions on a single box, the availability gets higher because when there is a software failure the second partition takes it over.
