Data mapping for a RAID Level 0 array is shown. Following the working principles of RAID Level 1 array, how you would like to fill the following physical disks from the stripes available in logical disk in the given diagram
COMPUTER ORGANIZATION AND ASSEMBLY LANGUAGE (plzz no chegg answer) Data mapping for a RAID Level 0 array is shown. Following the working principles of RAID Level 1 array, how you would like to fill the following physical disks from the stripes available in logical disk in the given digram:
A certain moving arm disk storage, with one head, has the following specifications. Number of tracks/recording surface = 200 Disk rotation speed = 2400 rpm Track storage capacity = 62,500 bits The average latency of this device is P msec and the data transfer rate is Q bits/sec. Write the value of P and Q.
There are many parameters that could be used to describe disk performance; among them are: number of bits per track disk capacity (in bits) number of disk surfaces rotational speed rotational latency transfer rate tracks per surface sectors per track blocks per track sectors per block seek time speed of disk arm block-read time number of blocks Some of these parameters are independent, and others are (approximately) linearly related. That is, doubling one doubles the other. Decide which of these parameters are linearly related. Then, select from the list below, the relationship that is true, to within a close approximation. Note: none of the statements may be true exactly, but one will always be much closer to the truth than the other three. Also note: you should assume all dimensions and parameters of the disk are unchanged except for the ones mentioned. a) If you divide tracks into half as many blocks, then you double the read time for a block.…

In a RAID 5 configuration of four 1TB solid state disks, the total available storage is ___ TB. Enter the number in TB only, e.g., 7.
Calculate 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.
Put a checkmark in the column if the address for that row falls on the boundary type for the column.
