NEW QUESTION # 36
Question:
A company is experiencing slow write performance on its RAID 6 array. What is the most likely cause of this performance bottleneck?
- A. Insufficient storage on the RAID controller
- B. Write penalty associated with dual parity calculations
- C. Increased network latency between the server and the storage array
- D. High read I/O load on the array
Answer: B
Explanation:
RAID 6 uses dual parity to provide fault tolerance, which requires additional calculations during write operations. This introduces a write penalty, as the system must compute and write two sets of parity data for each write operation, leading to slower write performance compared to other RAID levels.
* Insufficient storage on the RAID controller:Would affect storage capacity, not write performance.
* High read I/O load on the array:Impacts read performance, not write performance.
* Increased network latency:Affects data transfer times but not the internal write operations of the RAID array.
* Write penalty associated with dual parity calculations:The most likely cause of slow write performance in RAID 6.
