What's so special about this? 160TB per rack isn't that much. With 2TB drives in http://www.supermicro.com/products/chassis/2U/826/SC826TQ-R8... you can get 480TB per rack, and once http://www.supermicro.com/products/chassis/4U/847/SC847E16-R... comes out you'll be able to get 900TB per rack. Though cooling may become a challenge...
