Erasure Encoding Chunks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

 

Does anybody have any input on what the best ratio + total numbers of Data + Coding chunks you would choose?

 

For example I could create a pool with 7 data chunks and 3 coding chunks and get an efficiency of 70%, or I could create a pool with 17 data chunks and 3 coding chunks and get an efficiency of 85% with a similar probability of protecting against OSD failure.

 

What’s the reason I would choose 10 total chunks over 20 chunks, is it purely down to the overhead of having potentially double the number of chunks per object?

 

Nick
