Which of the following statements about the erasure code N+M redundancy by Huawei OceanStor 9000 is false?

  • Different data protection levels can be set different directories and files.
  • Data written to an OceanStor 9000 is divided into chunks at a size of 4GB.
  • The erasure code algorithm calculates M parity chunks for every N consecutive chunks.
  • The utilization rate of storage space is about N/(N+M), and reliability is determined by M, where a larger value of M results in higher reliability.
