Answer the following regarding RAID levels.a. Before adding the redundancy data, our RAID drive has 4 disk drives. If we choose RAID 1, how many extra drives do we need to add to store redundancy? RAID 5? RAID 6?b. We decide to use RAID 0 because we want our RAID drive to support multiple accesses as much as possible (that is, multiple different processes accessing disk simultaneously). Should we use small stripes or large stripes? Explain.c. RAID 4 is not used, why not? What RAID level would we use in place of RAID 4?
Which of the following statements about RAID 1 are correct? Check all that apply.
Group of answer choices
a. Increased fault tolerance compared to a single disk or RAID 0
b. Reduced cost per GB
c. Increased write performance compared to a single disk
d. Increased read performance compared to a single disk
You have a report of a customer with a Hard Disk Drive with bad sectors on /dev/sdr, what would you do to confirm the serial number and identify the disk with bad sectors? If it was in a Linux RAID, what commands would you run to remove it from the array and add a new disk?
