    If a vendor is really saying things like "you'll never see over 250Mbps with iSCSI" then that vendor is crazy.  Our old fiber channel vendor told us we'd never be able to exceed 250MB/s which, assuming only a single array and two paths is probably true.  Of course my counter point was that I didn't need to exceed 250MB/s in my environment to achieve my performance goals so why should I pay for more than that?  They didn't seem to understand that point.
