1.4 [20/10/20] Figure 1.23 presents the power consumption of several com- puter system components. In this exercise, we will explore how the hard drive affects power consumption for the system. a. [20] Assuming the maximum load for each component, and a power supply efficiency of 80%, what wattage must the server's power supply deliver to a system with an Intel Pentium 4 chip, 2 GB 240-pin Kingston DRAM, and one 7200 rpm hard drive? b. [10] How much power will the 7200 rpm disk drive consume if it is idle roughly 60% of the time? c. [20] Given that the time to read data off a 7200 rpm disk drive will be roughly 75% of a 5400 rpm disk, at what idle time of the 7200 rpm disk will the power consumption be equal, on average, for the two disks? 1.5 /10/2015>e critical factor power a sefer farm is cooling If heat Are roydon the Aputy effcien, hefs vivond any do Va compu not oldir . y will box at he difft ign si aft ct theces y cools, and thus the rice, of a system.
