Abstract

There exists data in a customer environment that must be optimized for faster writes (such as airline reservation centers or similar applications). A need exists to leverage Solid State Drives for this purpose in a cost efficient manner. As Sub-LUN optimization and other automatic tiering algorithms advance, such a leveraged system would have increased value.
