Re: IBM i vs VIOS for Host Partition

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

VIO Server can run with both internal and external storage as can IBM i 
hosting.  I don't have partitions that are big enough to stress them 
out, but customers have done both IBM i hosting and VIO  Server 
hosting.  Neither one seems to outrun the other in the workloads they 
have (10K transactions/hour with plenty of DASD arms), but there is a 
big difference in the management of them.  VIO Server might be slighly 
more flexible and has a few features IBM i hosting does not, IBM i 
hosting is much simpler to set up and requires a much lower learning 
curve.    I think the  larger the environment the more VIO Server tends 
to be the better choice, but that is very arguable.
