FC != Ethernet and IP doesn't run over FC.

So no this won't work.

You could look at setting up the CentOS box as a FC initiator to  
connect to the fiber storage and bypass the whole storage server mess.

We got rid of MSSS at my work due to it's unreliable performance, and  
the fact that it needed a reboot monthly for security updates which is  
a pain when you have a cluster and a bunch of virtualization hosts  
running off it. The reboot was like power downing 50% of the network  
once a month!

Switched to CentOS as the storage server and didn't look back.
