If the Airbus A380 and the space shuttle had a love child, it would be both large and fast. Thatís the 8420. It is fast, with a 2.8 Ghz processor, dual gigabit interfaces, and SATA drives. It has a huge capacity, with a 3.2 Terabyte maximum array for 680 DVDs, or four thousand CDs. This huge capacity does not take up a great deal of space: the 8420 comes in a 2u package, easily accomodated in your data rack. Your optical network problems are solved. You can go on to the next problem.
