I am now confused. Is somebody trying to save power by adding an i/o coprocessor? (with it's own power overhead for memory, i/o, etc) To me it is simple: 1) If you have an infinite power budget (big box), you might as well let the main cpus do the raid stuff. If you are short on power (embedded), you cannot afford to power an extra processor (+memory and stuff). 2) If you have rich customers (big box), let them pay for a bigger main cpu to do the raid, if you want to be cheap (embedded, appliance), you cannot afford to plop an extra cpu (+support chips) on your custom pcb. -- Konstantin Olchanski Data Acquisition Systems: The Bytes Must Flow!
