Step by step
Solved in 2 steps
- 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.On disk, operating systems endeavor to store files in sequentially arranged blocks. The usage of magnetic disks appears superfluous for this operation.Do you suppose SSDs are required if you do not use them? Exists a justification for this occurrence?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.
- On a 16 GB hard disk drive (HDD), each cluster consists of 32 sectors and each sector has a fixed size of 512 bytes. A text file with a size of 150,000 bytes is to be stored. a. i.What is the size of the slack space, in bytes, once the file has been stored?01. Consider a disk pack with 16 surfaces, 128 tracks per surface and 256 scctors per track 312 bytes of data are stored in a bit serial manner in a sector. The capacity of the disk pack and the number of bits roquired to specify a particular sector in the disk are respectivelyCalculate how much disk space (in whole sectors and tracks) will be required to store 1GB (230 bytes) of data if a disk is single-zoned with 512 bytes/sector and 1024 sectors/track. Ignore any file header record(s) and track indices.
- 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.The disk specification in Figure 7.15 gives a data transfer rate of 60MB per second when reading from the disk, and 320MB per second when writing to the disk. Why are these numbers different? (Hint: Think about buffering.)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?CPU with interrupt-driven I/O is busy servicing a disk request. While the CPU is midway through the disk service routine, another I/O interrupt occurs. Q.) Is it a problem?There is sequence of disk track requests: 75, 62, 99, 144, 50, 162, 110, 26, 198. Assume that the disk head is initially positioned over track 100, and is moving in the direction of decreasing track number. For SCAN algorithm A)What is the tracking order? B) What is Average Track Length?
