A company needs a media server set up that provides the highest availability with a minimum requirement of at least 10TB. The company purchased five HDDs, each with a 4TB capacity. Which of the options would provide the highest fault tolerance and meet the requirements?
正解:C
RAID 6 is a RAID level that uses disk striping with two parity blocks distributed across all member disks. It can tolerate the failure of up to two disks without losing any dat a. RAID 6 can provide a minimum of 10TB of usable storage space with five 4TB disks, as the formula for calculating the RAID 6 capacity is (n-2) x Smin, where n is the number of disks and Smin is the smallest disk size. In this case, the RAID 6 capacity is (5-2) x 4TB = 12TB.
