What is skew?

• A. Uniform distribution of I/O over storage capacity
• B. Sustained per-port IOPS
• C. Non-uniform distribution of I/O over storage capacity
• D. Bursty per-port IOPS

Answer: C

Explanation:
Skew refers to the non-uniform distribution of I/O over storage capacity. In storage systems, skew isan important factor to consider as it indicates that certain areas of the storage receive more I/O operations than others. This can lead to performance hotspots and affect the overall efficiency of the storage system. Managing skew is essential to ensure balanced performance across the storage array.
