How does RAID2 work please explain in simple language?

Question

RAID

Hello! I'm learning about RAIDs and I came across this definition as RAID2, so how do I understand this "Hamming Code Fault Tolerant Array"? The rest of the RAIDs (0, 1) have already figured out how they work, but I can't reason with RAID2.

Answer 1

In telecommunication, Hamming codes are a family of linear error-correcting codes that generalize the Hamming(7,4)-code, and were invented by Richard Hamming in 1950. Hamming codes can detect up to two-bit errors or correct one-bit errors without detection of uncorrected errors.

In raid1, if data is corrupted, you won't know about the corrupted data.

Answer 2

Separators are needed . For example ideone.com/ETpApj
