The following table represents an 8-drive-wide RAID-RDP volume. The volume is degraded with two failed drives: D1 and D2. Question 1: Write down the order
The following table represents an 8-drive-wide RAID-RDP volume. The volume is degraded with two failed drives: D1 and D2.
Question 1: Write down the order in which data blocks can be recreated.
Question 2: Write down the reconstructed values.
Mark the table with the order, XOR calculation, and reconstructed value. Also enter the answers in the Text Submission box, following the format described in the CS797K How to do RAID Assignments Word document.
