I heard rumors that VIO is that CPU expensive and that I/O is that fast nowadays, that it is VIO is not worth the extra CPU anymore.
Therefor I have been thinking about abandoning VIO, but I can't make a good calculation. I could make the calculation for the SAS WORK file, which can be in VIO or in HIPERSPACE. The latter is cheaper, as is stated by SAS and it is easy to switch to Hiperspace with a simple installation parameter. Does anyone has some figures on other use of VIO?

The nasty answer to "what happened to VIO?" is "nothing". :-) :-( Seriously, it remains as before but implemented in central storage rather than expanded. With the improved economics of memory it's worth looking at again - but only if memory is available to support it.
