Question
You are configuring a RAID 4 array for a high-traffic database server. One of the data disks fails. What happens to the system's performance during this disk failure?1.0 Marks The system switches to read-only mode.System performance remains unaffected.System performance degrades significantly.The system automatically shuts down.System performance improves.
Solution
The system's performance degrades significantly. RAID 4 uses a dedicated parity disk to store parity information, which allows for data recovery in case of a disk failure. However, when a disk fails, the system has to reconstruct the lost data from the parity information, which puts a significant load on the system and degrades performance. This is especially noticeable in a high-traffic environment like a database server.
