What is the average time to read or write a 512-byte sector for a typical disk rotating at 45,000 RPM? The advertised average seek time is 2 ms, the transfer rate is 400 MB/sec, and the controller overhead is 0.2 ms. Assume that the disk is idle so that there is no waiting time.
Discuss the concept of RAID (Redundant Array of Independent Disks) configurations and their applications in data storage and fault tolerance.
Question 1 Computer Science Assume updating one block of data to a RAID-5 storage takes c ms. What is the cost for updating two blocks of data to the storage? Give the reasons. • Hint: consider to store the blocks on the same disk, different disks in the same stripe, and different disks in different stripes.
What is the average time to read or write a 512 bytes sector for a disk? The advertised average seek time is 5 ms, the transfer rate is 40 MB/sec, it rotates at 10,000 RPM, and the controller overhead is 0.1 ms. Assume the disk is idle so that there is no queuing delay. In addition, calculate the time assuming the advertised seek time is three times longer than the measured seek time.
Explain RAID (Redundant Array of Independent Disks) and its various levels. When is each RAID level most appropriate?
Discuss the concept of RAID (Redundant Array of Independent Disks) and its different levels.
(b) Assume that a disk can perform a seek to an adjacent cylinder in 1 millisecond and a full-stroke seek over all 5000 cylinders in 18 milliseconds. The total seek times for FCFS is computed to be 65.20, SSTF is 31.52, SCAN is 62.02, LOOK is 40.29, C-SCAN is 62.10 and C-LOOK is 40.42. Which of the algorithms is the fastest? And what is the percentage speedup of the fastest algorithm over FCFS?
What are the implications of "bit rot" in long-term data storage?
Suppose that a magnetic disk has an average seek time of 4 ms, a rotation rate of 5400 RPM, a transfer rate of 50 MB/second, a sector size of 512 bytes, and controller overhead of 2 ms. What is the average amount of time to read a single sector?
Why are "parity bits" important in certain RAID configurations?
Consider a disk with following specifications: 20 surface, 1000 tracks/surface, 16 sectors/track, data density 1 KB/sector, rotation speed 3000 rpm. The operating system initiates the transfer between the disk and the memory sector-wise. Once the head has been placed on the right track, the disk reads a sector in a single scan. It reads bits from the sector while the head is passing over the sector. The read bits are formed into bytes in a serial-in-parallel-out buffer and each byte is then transferred to memory. The disk writing is exactly a complementary process. For parts (c) and (d) below, assume memory read-write time = 0.1 microsecond/ byte, interrupt driven transfer has an interrupt overhead = 0.4 microseconds, the DMA initialization and termination overhead is negligible compared to the total sector transfer time. DMA requests are always granted. (a) What is the total capacity of the disk? (b) What is the data transfer rate? (c) What is the percentage of time the CPU is…
