CV0-004 · Question #394
Which of the following does an engineer need in order to calculate the number of IOPS required in a storage resource?
The correct answer is D. Latency. IOPS (Input/Output Operations Per Second) is calculated using the formula: IOPS = 1000 ÷ average latency (in milliseconds). Latency-the time it takes to complete a single I/O operation-is the key variable needed to derive the number of operations the storage can handle per…

Explanation
IOPS (Input/Output Operations Per Second) is calculated using the formula: IOPS = 1000 ÷ average latency (in milliseconds). Latency-the time it takes to complete a single I/O operation-is the key variable needed to derive the number of operations the storage can handle per second. Without latency, you cannot compute throughput capacity. Network capacity (A) is relevant for network I/O, not storage IOPS directly. Block size (B) affects throughput (MB/s) calculations, not raw IOPS. Memory utilization (C) relates to caching efficiency, not storage operation rate.
