A prospect provides the following details for sizing active working set based on their existing...

To calculate the minimum amount of required SSD storage for the active working set:

Determine the active working set size:

The data growth pattern shows an increase of 1TB per month.

Considering the most recent data point (May: 14TB), the active working set can be approximated as the difference between the highest and the lowest value in the given period.

Consider the read/write ratio:

Average Read/Write Ratio: 75/25

Typically, write operations require more SSD space for better performance.

SSD storage calculation:

Given the active working set and growth pattern, a prudent estimate would be to ensure sufficient SSD space to handle peak loads and ensure performance.

Based on the pattern and industry best practices, 6TB of SSD storage would be a reasonable minimum to accommodate the active working set and ensure performance.
