Quick guide to disaster recovery in the cloud  Silicon Graphics
has a need for speed. Or, more precisely, some of its customers
do, and those customers also have money to burn.  Supercomputer
maker Appro International launched its HF1 overclocked server
for hedge funds and other financial firms back in October, and

dissipation - financial trading companies and the stock, bond,
