instead of one pump sucking from the pan, and feeding the engine, you get two pumps. One takes the oil out of the oil pan (sump), causing it to run dry (hence the name). It pumps it into a storage tank. The second pump, takes oil from the tank and pumps it into the engine.
In theory, the sump pump runs faster than the engine pump, so you never run the tank out of oil, and therefor never starve your engine of oil. Also, in a wet-sump system (normal C5/C6) the oil sloshes as you corner/brake, and if the oil is low enough, you could momentarily starve the oil pump and engine of oil. With a dry sump, the oil tank is design so that even as the oil sloshes, the output at the bottom of the tank always has oil readily available.

dry sump moves the oil pan out from under the block. this allows you to drop the engine lower and thus lower center of gravity. cool stuff.
