QuestionQ19

Server hardware installation and management

An administrator is diagnosing an application performance problem. The application carries out many small reads and writes during operation. The administrator finds that the underlying storage is currently configured as a general-purpose RAID 5 array. Which action should the administrator consider to provide higher application performance while still maintaining data protection?

Explanation

RAID 10 combines mirroring and striping, so it preserves data redundancy while avoiding the parity-calculation overhead that makes RAID 5 inefficient for frequent small writes. It is therefore better suited to a small, mixed read/write workload than RAID 5 or RAID 6, while RAID 0 provides no fault tolerance.
