How does the Tiger system cope with a large number of clients all requesting the same movie at random times?

What will be an ideal response?

If they arrive within a few seconds of each other, then they can be placed sufficiently close together in the schedule to take advantage of caching in the cubs, so a single disk access for a block can service several clients. If they are more widely spaced, then they are placed independently (in an empty slot near the disk holding the first block of the movie at the time each request is received). There will be no conflict for resources because different blocks of the movie are stored on different disks and cubs.
