First, is there a real need for 10GbE? Have you measured an I/O bottleneck at the network layer?
Second, if your budget is tight enough to be considering a $1000 10GbE desktop switch, have you budgeted for the ports and cables? We paid $600 each just for the 10GbE adapters from HP and then even using the cheap twinax SFP+ cables, they are another $300 a pop. So you are looking at close to $2000 per host (2 adapters + 2 cables) not even factoring in the switch. You probably can't afford to to 10Gb right, so I wouldn't.
Just on the surface, unless you have pressing needs for 10GbE that override stability, I would not run a production IP SAN on a desktop switch.
