I'm surprised
That the redundant VIOS for IBM i has only just made it out of the door.
For AIX, it has been possible to have 2 VIO servers providing multiple paths to your storage for at least 3 years, and it was being talked about when AIX 5.3 was announced, whenever that was. But I guess that the UNIX market place is a bit more aggressive, and AIX needed more of an advantage to leverage sales.
Wonder when they will get the partition mobility support.
