that would brutally kill performance.

That's my main problem.

Another option is emulate an iSCSI storage using iET, run multiple Windows guests and create a cluster between them. However, I don't know if that's a goog choice.

Did anyone create something like that? Does anyone have another idea?

Thanks a lot.
