Fault Tolerance Techniques

A storage system uses erasure coding with 10 data segments and 2 coding segments. Each segment is written to a different drive.

What is the maximum number of drive failures this configuration can withstand without data loss?

Explanation

Two coding segments provide redundancy for up to two lost segments. Because every segment resides on a separate drive, the configuration can tolerate failure of two drives without losing data.
