It should be clear that disk striping can improve data transfer rate when the strip size is small compared to the I/O request size. It should also be clear that RAID 0 pro- vides improved performance relative to a single large disk, because multiple I/O re- quests can be handled in parallel. However, in this latter case, is disk striping necessary? That is, does disk striping improve I/O request rate performance com- pared to a comparable disk array without striping?

For a computer with 56-bit physical addresses and a 8-way set associative cache of 64 KB where each cache line has the capacity of holding 32 words. Assume the word size is 3 and the architecture is byte-addressable. Answer the questions below: a.How many bits are needed for tag, index, word offset, and byte offs. Show your derivations and assumptions. b.What are the start and end physical addresses, in hex as discussed in class, for cache line 300? Cache line count starts from 0. c.What is the total size, in KB, of this cache? d.What is the tag value, in hex, of address 0xABCDEF98765432?

Go out the concept of wear leveling and elaborate on why it's so important for SSDs. We've shown that wearleveling is fundamental for the ongoing refresh of virtual memory pagefiles. Why does wearleveling exacerbate the problem with pagefiles?

It is given that on a system, on average, an instruction executes in 1 nano second. Suppose that it takes 20 micro seconds of processor time for page fault. While, it takes 300 micro seconds of disk time for reading and writing a single page. Suppose that on average 1/3 of the pages that need to be paged out are modified. What is the average number of instructions between page faults that would cause the disk to be busy doing page transfers all the time?
