After deploying a new all-flash storage array, which results would best meet the requirements for storage efficiency and latency?

1. Compression 1:1, Deduplication 4:1, Average latency 1.0ms.

2. Compression 1.5:1, Deduplication 1.8:1, Average latency 600us.

3. Compression 1.3:1, Deduplication 3.1:1, Average latency 900us.

4. Compression 1.8:1, Deduplication 2.7:1, Average latency 1.2ms.

The correct answer is: Compression 1.8:1, Deduplication 2.7:1, Average latency 1.2ms.

The chosen option emphasizes balancing both storage efficiency and latency, two crucial factors in an effective storage solution. In this case, compression and deduplication ratios indicate how effectively data is reduced in size, leading to increased storage efficiency. A ratio of 1.8:1 for compression means that for every 1.8 units of data, only 1 unit is stored, which reflects a robust level of data reduction. Similarly, a deduplication ratio of 2.7:1 suggests that for every 2.7 units of data stored, there is substantial reduction by eliminating duplicate copies, which significantly enhances storage capacity. The latency of 1.2 milliseconds, while higher than some of the other options, remains within a competitive range for many applications, particularly when balanced against the significantly improved storage efficiency resulting from the compression and deduplication values. This combination of high compression and deduplication with a manageable latency positions this option well for environments that prioritize both effective resource utilization and performance, meeting organizational needs for streamlined operation and responsiveness in data access.
