You could swing this if they are FC attached hosts (decent array required). This is going to pretty much be determined by your storage system and it's connectivity. iscsi/nas is ethernet, which MIGHT burst that high, but rarely (I've never actually seen or heard of it sustaining anything over about 45% of link capacity). Whereas FC does this fairly easily (depending on your system).

Can you do it? Yes. Depends on what you have. It may be that your setup does not support it, not every server is better off virtualized, simply because it might be cheaper to do it physically (it would certainly be cheaper to build a local server with the prerequisistes to complete this task than it would to be buy an array and fc network if you did not already own it--if it was for a single instance).

I may be misunderstanding what you are asking for, if I am, please direct further.
