What does Pure Storage's Right-Size Guarantee promise?

Pure Storage'sRight-Size Guaranteepromises theeffective capacity of the FlashArray, ensuring that customers receive the logical capacity they expect based on their workload's data reduction profile.

Why This Matters:

Effective Capacity:

Effective capacity refers to the logical capacity available after applying data reduction techniques like deduplication, compression, and pattern removal.

The Right-Size Guarantee ensures that customers achieve the expected effective capacity for their workloads, aligning with Pure Storage's commitment to delivering predictable and reliable storage solutions.

Customer Assurance:

If the actual effective capacity does not meet expectations, the customer can work with their SE to address the issue, potentially adjusting their subscription or configuration.

Why Not the Other Options?

A. The performance of the FlashArray model:

The Right-Size Guarantee does not specifically address performance metrics like latency or IOPS. It focuses on capacity-related assurances.

C. The Data Reduction Rate by workload:

While data reduction contributes to effective capacity, the guarantee is not tied to a specific data reduction rate. Instead, it ensures the overall effective capacity meets expectations.

D. The customer's Total Efficiency Ratio:

The Total Efficiency Ratio combines data reduction and other factors but is not the focus of the Right-Size Guarantee.

Key Points:

Effective Capacity:The guarantee ensures customers receive the expected logical capacity based on data reduction.

Data Reduction Techniques:Deduplication, compression, and pattern removal contribute to effective capacity.

Customer Support:Customers can collaborate with their SE if the guaranteed capacity is not achieved.
