Question 2: Consider a disk with the following characteristics (these are not parameters of any particular disk unit): Block size B=512 bytes, Number of blocks per track =20, Number of tracks per surface =400. A disk pack consists of 15 double-sided disks. A. What is the total capacity of a track? B. How many cylinders are there? C. What is the total capacity of a cylinder? D. What is the total capacity of a disk pack? E. Suppose the disk drive rotates the disk pack at a speed of 3000rpm (revolutions per minute): i. What is the transfer rate in bytes/msec? ii. What is the block transfer time (btt) in msec? iii. What is the average rotational delay (rd) in msec? F. Suppose the average seek time is 30msec. How much time does it take (on the average) in msec to locate and transfer a single block given its block address? G. Calculate the average time it would take to transfer 20 random blocks and compare it with the time it would take to transfer 20 consecutive blocks
