How to vMotion during tape backup

I need to figure out a solution for a VMs that are connected to a tape backup.  Currently the solution uses a physical server with a scsi connection another physical server uses a usb connection to a tape backup.

For example - for the USB connected tape backup - if I install a usb-over-ip hub - would that work?  Will it allow the Vm to connect to the IP and be able to vmotion without making the backup job fail?  If not is there a better solution?

For the scsi connected tape backup - is there a similar or better solution?

I want the Vm to be able to move among all physical servers in the cluster and be able to restart on any new server.  I don't want to have to hardwire the VM to scsi passthrough on any single physical server.

Thanks for your ideas!
