Suppose you have multiple disks. You can configure them as a spanned volume, a striped volume with parity, or a mirrored volume. a. Given a specific total disk capacity (for example, four disks that are 4 TB each for a total of 16 TB), the actual usable space for data storage is not the same for each approach. That is, you cannot actually store data files totalling 16 TB in size using all three approaches. List the three approaches in order of actual usable data storage space, from highest to lowest b. How resistant is each approach to drive failures? c. In light of 2a and 2b, how would you decide which of these approaches to use in a given situation? 11:45 PM
