BYu calculate M check blocks (N=+M) by Erasure code algorithm for every N consecutive data blocks

CThe system stores N + M data blocks in parallel on different hard disks

DIn re-Erasure Code storage mode, the system supports up to N hard disk failure

N+M, huh? Sounds like a new math equation I need to learn. Maybe I can get bonus points if I solve for X while I'm at it.

Alright, let's focus here. The key is understanding the principle of Erasure code N+M. I think the correct answer is D, since the system should support up to N hard disk failures, not just M.

Haha, 'wong'? I think the person who wrote this question needs to brush up on their English. Maybe they're trying to be funny, but it's a bit cringeworthy.

Okay, let me think this through. If the system stores N+M data blocks in parallel, then it should be able to tolerate up to M disk failures, not just N. That must be the 'wong' statement.

So, the statement saying the system supports up to N hard disk failure is wrong.

Wait, isn't Erasure code supposed to be more reliable than RAID? Why would the question say the statement about N+M is 'wong'? I'm a bit confused.

Hmm, I see your point. But I still think A) makes more sense because it's about how the data is initially written.
