Storage Network Design

An engineer needs to create a Cisco UCS storage disk group policy that delivers high redundancy, fault tolerance, and enhanced read performance. The configuration must maintain data integrity if as many as two disks fail, use at least four disks and dual parity blocks, and optimize for greater read bandwidth to improve application performance. Which RAID level must be selected to meet this objective?

  • A RAID 5
  • B RAID 6
  • C RAID 10
  • D RAID 50
Explanation

RAID 6 stripes data across at least four disks and maintains two parity blocks, so it preserves data integrity through up to two disk failures. Its striping also allows reads to be distributed across the disks, increasing read bandwidth.
