Problem1 when file systems replicate files they do not, Ask an Expert

Engineering

Problem

1. When file systems replicate files, they do not normally replicate all files. Give an example of a kind of file that is not worth replicating.

2. A file is replicated on 10 servers. List all the combinations of read quorum and write quorum that are permitted by the voting algorithm.

3. With a main memory file server that stores files contiguously, when a file grows beyond its current allocation unit, it will have to be copied. Suppose that the average file is 20K bytes and it takes 200 nsec to copy a 32-bit word. How many files can be copied per second? Can you suggest a way to do this copying without tying up the file server's CPU the entire time?
