If SSI could do it, then by all means, I'll accept nostalgia. I'm not
approaching this from a PC person's standpoint. Those that know me know that
I have been a VM'er all the way back to VM/SP 1. And I tested SSI on our
systems back in that day.
VM's great, but this is something that it currently DOES NOT ADDRESS, even
though it exists today in complexes running multiple CECs and interested in
24x7 operations. Being able to move a running image from one VM to another
would address an immediate and pressing need for me. And it¹s one that our
PC brothers hold up as a reason that their solution is ³better² than ours.
They can swap hardware without bringing down the underlying operating
systems. We can¹t. It¹s just that simple, from a needs standpoint.
I realize that the concept¹s implementation is non-trivial. But, it is
something that is needed in order to implement 24x7 support in a world where
applications can¹t really perform in that manner.
