I should post this to the Linux list also, but I'll start with the

On a VM system hosting Linux guests,
I can think of one or two reasons why one might
want to use EDEV instead of direct SAN connections.
There are also some reasons why one would NOT want to.
Can any of you think of reasons you would go one way or the other?
Given a Linux guest on z/VM using SAN,
should it go direct or go via EDEV? If direct, why? If EDEV, why?
Thanks.
I hope to add a slide to my SHARE pitch on this topic.
How are the performance implications in 5.3? I know in 5.2 EDEV was
much slower.
If performance is adequate, *I* think it's tons easier to let VM
manage that; then you have to deal with SAN ugliness in only *one*
place.
