Consider the following breakdowns of the power consumption of a server:

CPU, 50%; memory, 23%; disks, 11%; networking/other, 16%
CPU, 33%; memory, 30%; disks, 10%; networking/other, 27%

a. Assume a dynamic power range of 3.0
for the CPU (i.e., the power consumption of the CPU at idle is one-third that of its power consumption at peak).
Assume that the dynamic range of the memory systems, disks, and the networking/
other categories above are, respectively, 2.0, 1.3, and 1.2. What is the overall dynamic range for the total system for the two cases?

b. What can you learn from the results of part (a)? How would we achieve better energy proportionality at the system level
