A customer has purchased an N8500 clustered NAS storage system configured with SATA and NL-5AS disks. To balance RAID reliability with read/write performance, which of the following configuration plans is recommended?

  • A 11-disk RAID 5 and one hot spare disk
  • B 11-disk RAID 6 and one hot spare disk
  • C 4-diskRAID10
  • D 9-disk RAID 5
Explanation

For SATA and NL-SAS drives, an 11-disk RAID 6 group with one hot spare provides dual-disk fault tolerance and allows rebuilding to begin immediately after a disk failure. This delivers stronger protection than RAID 5 while preserving more usable capacity and generally better efficiency than RAID 10.
