Dell EMC Associate – Information Storage and Management v4 — Question 17
In a RAID 6 array with four disks, what is the total usable data storage capacity on the array if the disk size is 200 GB?
Answer options
- A. 200 GB
- B. 400 GB
- C. 600 GB
- D. 800 GB
Correct answer: B
Explanation
In a RAID 6 configuration, two disks are used for parity, which means that the total usable capacity is calculated by taking the total number of disks minus two. Hence, with four 200 GB disks, the usable capacity is (4 - 2) * 200 GB = 400 GB. The other options do not account for the parity disks correctly.
