• Question 296:

  Which of the following statements about reading and writing an N8500 clustered NAS file system mirror and the best practices are correct? (Select three)

  A. Equivalent to RAID 01, Mirrored-stripe is to perform file system mirroring based on striping, A mirror provides data redundancy, and data is distributed across multiple disks.
  B. Mirror is equivalent to RAID 1, Data that needs to be written to a file system is simultaneously written to two mirrors and data is read from the two mirrors based on a round- robin policy (I/Os are evenly distributed to paths in a round-robin manner).
