In a server, the processor accounts for 50% of total server power, the memory system accounts for 30%, the disk accounts for 10%, and miscellaneous components account for remaining 10%.  You have a $500 budget to upgrade your server to make it more power efficient.  You plan to either replace your memory module with a new memory module or your disk with a new disk. With the budget you can either purchase a new memory module that consumes 40% less power than your old memory module, or a new disk that consumes 40% less power than the old disk.  which would you choose to purchase if you were only worried with reducing your servers power consumption?
