3. [5 pts] Without consulting the IT staff first, company management has purchased a new set of hard disks that it hopes will provide significant speedup of company servers. Specifically, the disks will provide 6 times the performance of the current disks (i.e., 400% faster). Management's hope is that the new overall system performance will be at least 1.8 times the current system performance (i.e., 130% faster overall). What is the maximum amount of time (in %) that the system could spend doing disk I/O and still provide the desired overall system speedup of 130%? (Note: This kind of problem does not appear in the lecture notes or practice problems, but does involve Amdahl's Law. Put on your thinking cap!) 3.

To solve this problem we can use Amdahls Law which relates the speedup of a system to the fraction of the system that is improved Amdahls Law is given by the formula Speedup 1 1 P P S where Speedup is ... View the full answer
