Assume you have a system where you need to maintain operability even during the failing, replacing, and rebuilding of a failed disk. Thus, the data in the failed disk must be rebuilt and written to the replacement disk while the system is in operation. Which of the RAID levels yields the least amount of interference between the rebuild and ongoing disk accesses?

RAID level 1 fits the criteria to yield the least amount of interference between the rebuild and ongoing disk accesses.

Explanation:

RAID system can be defined as the process in which hard drives which are connected to the system are been set up in order to help speed up the performance of a computer system disk storage which is why RAID is mostly used on servers and high performance computers system . This RAID as well helps to combines multiple physical disk drive components into various logical units for the aim of increasing system performance.

Therefore RAID level 1 fits the criteria to yield the least amount of interference between the rebuild and ongoing disk accesses. This is because the level 1 of RAID copies just the data from the failed Systems disk mirror during the rebuilding period where as the other levels of RAID copies the whole lot of content of the other disks due to the fact that RAID 1 often requires at least minimum of two physical drives because data is written simultaneously to two places in which the drives are essentially mirror images of one another in which if one fails, the other one can take over and help to provide access to the data that is been stored on that drive.

no. when the asker posts the question they can make a question worth what ever they think is a fair price. although it must be within the limit of the points they currently own. 5 is the minimum number of points a question can be worth. if a question is complicated or has lots of parts to it, it is better to make it worth more because more people will be more willing to answer.

hope this !
